                                 PART I

Item 1.  Business
     Minerals Technologies Inc. (the "Company") is a resource- and 
technology-
based company that develops, produces and markets on a worldwide
basis a broad range of specialty mineral, mineral-based and synthetic
mineral products. The Company's principal products are: precipitated
calcium carbonate ("PCC"), used primarily by paper producers in the
alkaline papermaking process; monolithic and shaped refractory materials,
used primarily by the steel, cement and glass industries; and natural
mineral and mineral-based products, used primarily in the building
materials, steel,  paints and coatings, glass, ceramic, polymers, food and
pharmaceutical industries. The Company emphasizes research and development.
The level of the Company's research and development spending as well as its
history of developing and introducing technologically advanced new products
has enabled the Company to anticipate and satisfy changing customer
requirements and create new market opportunities through new product
development and product application innovations. 

PCC Products and Markets

     PCC Products.

     Paper can be produced under either acid or alkaline conditions.
Historically, in North America, paper was primarily produced using acid
technologies.  In the mid-1980's, North American producers of uncoated
wood-free paper encountered significant increases in the cost of wood fiber
and other materials, such as titanium dioxide, which are necessary in
greater quantities in the acid process. In response, these paper producers
sought to convert their paper production to lower-cost alkaline-based
technologies, which permit mineral fillers to be substituted for more
expensive wood fiber and pigments used to increase brightness, resulting in
significant cost savings. As a result of these conditions, the Company
believed that a significant opportunity existed to provide paper producers
with a high performance filler product that could facilitate the transition
to the alkaline papermaking process. The Company's four-year development
effort culminated in the construction of the first commercial satellite PCC
plant at the Wisconsin Rapids paper mill of Consolidated Papers, Inc. in
1986. The Company believes the competitive advantages offered by the
improved economics and superior optical characteristics of the paper
produced using the PCC products manufactured by the Company's satellite PCC
plants resulted in the rapid growth in the number of the Company's
satellite PCC plants among uncoated wood-free paper producers. The Company
has also built satellite PCC plants that replace ground calcium carbonate. 
In addition, the Company has constructed satellites for coating PCC and
more recently satellites for the use of its patented acid-tolerant PCC
technology.  This technology provides higher performance qualities to
manufacturers of groundwood paper like newsprint, magazine and catalogue
papers.  The following table shows the number of satellite PCC plants
operated by the Company at the end of the periods indicated. For
information with respect to the locations of the Company's satellite PCC
plants at December 31, 1997, see "Item 2--Properties" below.

     In 1997, the Company commenced operations at five new satellite PCC
plants 
in five different countries.  These satellite PCC plants are located
in the United States, Slovakia, Indonesia, Finland and South Africa.
     During 1997, the Company signed agreements to construct six new
satellite plants--four of which are now under construction.  The satellite
PCC plants under construction are located in France, Germany and the United
States.

 1


     The Company staffs, operates and maintains all of its satellite PCC
plants and owns the related technology used at its satellite PCC plants.
The Company and its paper mill customers enter into long-term agreements,
generally ten years in length, pursuant to which the Company supplies
substantially all of a customer's precipitated calcium carbonate filler
requirements. The Company is generally permitted to sell to third parties
PCC produced at a satellite plant in excess of the host paper mill's
requirements. The Company's satellite PCC plants and customers are listed
in Item 2 -- "Properties."

     The Company currently manufactures several customized PCC product
forms through proprietary processes at its satellite PCC plants, each
designed to provide optimum brightness, opacity, bulking and/or paper
strength. While focusing on expanding sales at its existing satellite PCC
plants, the Company's research and development and technical service staffs
have pioneered a number of ancillary new technologies. These include
acid-tolerant PCC, which allows PCC to be introduced to the large
wood-containing segment of the printing and writing papers market, and
production of PCC crystal morphologies for coating paper.  The Company
expects that research and development in coating technology will open up a
larger market for PCC that will build slowly as paper companies begin to
include PCC in their proprietary coating formulations.

     The Company also produces a full range of slurry and dry PCC products
sold on a merchant basis. In the paper industry, the Company's merchant PCC
is used as a coating pigment and as a filler in the production of coated
and uncoated wood-free printing and writing papers. The Company sells
surface-treated and untreated grades of PCC to the polymers industry for
use in rigid polyvinyl chloride products (pipe and profiles), thermoset
polyesters (automotive body parts), sealants (automotive and construction
applications), adhesives, printing inks and coatings. The Company's PCC is
used by the food and pharmaceutical industries as a source of bio-available
calcium in tablets and foodstuffs, as a buffering agent in tablets, and as
a mild abrasive in toothpaste. The Company also sells PCC on a merchant
basis to the paints and coatings industry. 

     The Company's PCC product line net sales were $299.9 million, $263.1
million, $226.6 million for the years ended December 31, 1997, 1996 and
1995, respectively.  See "Item 7--Management's Discussion and Analysis of
Financial Condition and Results of Operations."


     Key Markets.

     The principal market for the Company's satellite PCC products is the
paper industry. The Company also produces PCC on a merchant basis for sale
to companies in the polymers, food and pharmaceutical and paints and
coatings industries. 

     Sales of PCC to the paper industry have accounted for a steadily
increasing percentage of the Company's total sales in the past five years,
a trend the Company expects to continue. The Company's sales of PCC have
been 
and are expected to continue to be made to the printing and writing
papers segment of the paper industry. The Company's products are currently
used primarily by paper mills producing uncoated wood-free paper. 

     North American Wood-Free Printing and Writing Papers. In the
mid-1980's, North American producers of uncoated wood-free paper
encountered significant increases in the cost of wood fiber and other
materials.  In response, these paper producers sought to convert their
paper production to lower-cost alkaline-based technologies, thereby
resulting in significant cost savings. Ground chalk has historically been
used by European alkaline-based paper producers as a low-cost substitute
for wood fiber. In North America, however, the use of ground chalk is not
practical as there is no naturally occurring chalk. 

     PCC must compete with other fillers, such as ground limestone and
clay, on a cost-effective basis. PCC costs more to produce than ground
limestone or clay since the production process is inherently more complex.
Limestone is mined, crushed and ground; clay is mined, ground and perhaps
calcined. PCC is manufactured via a chemical process which takes lime
(which itself is produced by calcining a mined product, limestone),
dissolves it, combines it with carbon dioxide and separates the final
product. Drying and transportation can add over $100 per ton to the product
cost.  If shipped wet, additional freight costs would be incurred.  The
Company believes that in many cases this added cost makes PCC from merchant
plants non-cost-competitive with other fillers. 

 2

     In response to these conditions and as a result of a concentrated
research and development effort, the Company developed the satellite PCC
plant concept. The Company's satellite PCC plants have facilitated the
conversion of a substantial percentage of the North American uncoated
wood-free printing and writing paper producers to alkaline papermaking. The
Company estimates that during 1997, more than 80% of North American
wood-free paper was produced employing alkaline technology. 

     Presently, the Company owns and operates 34 commercial satellite PCC
plants located at paper mills that produce wood-free printing and writing
papers in North America.  Based upon its experience, the Company
anticipates that the aggregate volume of PCC used by these 34 paper mills
will increase.  The Company also estimates that a few additional North
American paper mills producing wood-free paper are both suitable for
conversion to the more economical, and in the Company's view, more
ecologically sound, alkaline method and large enough to support a satellite
PCC plant.

     The Company is also placing increased emphasis on the use of PCC to
coat paper.  PCC increases gloss and printability of the sheet while
decreasing paper's cost per ton.  The coating market is large and the
Company believes it will continue to grow at a higher average growth rate
than the uncoated market, and therefore provides a substantial market
opportunity for the Company.  PCC coating products can be produced at
satellite PCC plants.

     Worldwide Wood-Containing Printing and Writing Papers. To date, the
Company's PCC products have primarily  been used in wood-free alkaline
papermaking processes. The wood-containing segments of the paper industry
still generally employ acid papermaking technology. The conversion to
alkaline technology by these segments has been hampered by the phenomenon
of alkaline darkening, the tendency of wood-containing papers to darken in
an alkaline environment. In an attempt to introduce PCC to the
wood-containing segments of the paper industry, the Company has developed
and patented a process for the manufacture of an acid-tolerant form of PCC
(AT[tm] PCC) that provides enhanced brightness and opacity properties
without the undesirable darkening phenomenon.  During 1997, the Company
signed three contracts for the use of its patented acid-tolerant PCC
technology which will enable the Company to expand its sales to makers of
groundwood paper grades.  

     The Company believes PCC filler levels for uncoated wood-containing
paper generally will be less than those for uncoated wood-free paper. There
can be no assurance as to the number of producers of wood-containing paper
that will contract with the Company to purchase AT [TM)PCC.

     International Wood-Free Printing and Writing Papers.  The Company
estimates the production of uncoated wood-free printing and writing papers
outside of North America that can be served by its satellite PCC operations
is approximately the same size (measured in tons of paper produced) as the
North American uncoated wood-free paper market currently served by the
Company. A number of factors have influenced the acceptance of the
Company's satellite PCC technology in foreign markets. Although European
wood-free paper producers predominantly use alkaline papermaking processes,
PCC is not in prevalent use in this market. Ground chalk is readily
available in Europe and commonly used as a low-cost filler product in
alkaline systems. In addition, supplies of lime suitable for the
manufacture of PCC generally are not available at attractive prices.
However, the Company believes that the superior brightness and opacity
characteristics offered by its PCC products should allow it to compete with
suppliers of ground chalk and other filler products in certain locations in
this market.   In Latin America and Asia, ground chalk is not readily
available, while supplies of lime suitable for PCC production are generally
available at attractive prices.

Refractory Products and Markets

     Refractory Products.

     The Company offers a broad range of monolithic refractory products as
well as pre-cast monolithic refractory shapes. Product sales are usually
combined with Company-supplied proprietary applications equipment and
on-site technical services support. The Company's proprietary applications
equipment is used to apply refractory materials to the walls of
steel-making furnaces and other high temperature vessels to maintain 
and extend their lives. Robotic-type shooters, including the Company's 
proprietary SEQUAD(R) sprayer, allow for remote-controlled applications 
in steel-making furnaces, as well as in steel ladles and blast furnaces. 
Since the steel-making industry is characterized by intense price 
competition, which results in a continuing emphasis by 

 3

steel mills on increased productivity, the SEQUAD(R) sprayer and the
related technologically advanced blast furnace maintenance materials
developed in the Company's research laboratories have been well accepted by
the Company's customers. These products allow steel makers to improve their
performance through, among other things, the application of monolithic
refractories to furnace linings while the furnace is at operating
temperature, thereby eliminating the need for furnace cool-down periods and
steel-production interruption. This also results in a lower overall
refractory cost to steel makers per ton of steel produced. The Company's
experienced technical service staff and advanced applications equipment
provide greater assurance that the desired productivity objectives of
customers are achieved. In addition, laser measurement of refractory wear
is conducted by the Company's technicians in certain plants. The Company
believes that these services, together with its refractory product
offerings, provide the Company with a strategic marketing advantage. 

     The Company has patented a new technology in the refractory product
line.  The KILNTEQ(R) refractory technology system is a new concept for
lining the interior of lime and cement kilns.  The KILNTEQ(R) system calls
for lining the huge, tube-like kilns with refractory material in a
polygonal shape.  This shape, rather than the circular linings now
generally used, is believed to increase raw material throughput and to
decrease energy use.  
     The Company's refractory products are sold in the following three
product groups:

     Steel Furnace Refractories.  The Company sells gunnable monolithic
refractory products to users of basic oxygen furnaces and electric furnaces
for application on furnace walls to prolong the life of furnace linings. 

     Specialty Products for Iron and Steel. The Company sells monolithic
refractory materials and pre-cast refractory shapes for iron and steel
ladles, vacuum degassers, continuous casting tundishes, blast furnaces and
reheating furnaces. The Company is one of the few monolithic refractory
companies offering a full line of materials to satisfy all continuous
casting refractory applications. This full line consists of gunnable,
sprayable, trowellable and vibratable materials as well as refractory
shapes and permanent linings. 

     The Company uses proprietary processes to produce a number of products
that are technologically enhanced. These include calcium metal,
metallurgical wire and a number of metal treatment specialties. The Company
manufactures calcium metal at its Canaan, Connecticut facility and
purchases calcium in international markets.  Calcium metal is used in the
manufacture of batteries and magnets. The Company sells metallurgical wires
and fluxes for use in the production of steel. The Company's metallurgical
wires are injected into molten steel to reduce imperfections. The steel
produced is used for high-pressure pipeline and other premium-grade steel
applications. The Company's fluxes are mineral products used to help purify
steel.

     Non-Steel Refractory Products. This product line encompasses
refractory shapes and linings that are sold to the glass, cement, aluminum,
petrochemical and other non-steel industries. 

     The Company's refractory net sales were $195.9 million, $192.2 million
and $202.5 million for the years ended December 31, 1997, 1996 and 1995,
respectively. See "Item 7--Management's Discussion and Analysis of
Financial Condition and Results of Operations."


     Key Markets.
 
     The principal market for the Company's refractory products is the
steel industry. For the year ended December 31, 1997, approximately 90% of
the Company's sales of refractory products was to the steel industry. Raw
steel production on a worldwide basis has shown only modest growth in the
past ten years.  However, management believes that certain trends in the
steel-making industry will continue to provide growth opportunities for the
Company. These trends include the development of improved manufacturing
processes such as continuous casting, the need of steel producers for
increased productivity and higher grade refractories as well as a modest
shift toward electric steel making. 

     The use of the continuous casting method, measured in tons of steel
cast on a worldwide basis, has more than doubled in the past ten years. The
need for high quality refractory products for this process has generated
new market opportunities for the Company's refractory products. Product
offerings for continuous casting include 

 4

advanced maintenance coatings and original linings for tundishes and
robotic applications equipment.  The Company believes that the trend toward
electric steel-making mini-mills and away from integrated steel mills has
facilitated the acceptance of new refractory products and technologies.
Mini-mills require a broad line of refractory products and certain
metallurgical products that are also produced by the Company. 
Processed Mineral Products and Markets

     The Company mines and processes natural mineral products, limestone
and talc, and manufactures lime, a mineral-based product.  The Company also
produces a number of technology-based products, including pyrolytic
graphite. 

     Over 60% of the Company's sales of limestone in 1997 were filler-grade
material, i.e., limestone having sufficient purity and color to enable it
to be utilized as a pigment and filler in building materials, paints and
coatings, polymers and joint compounds. The other component of this product
line represents sales of limestone aggregate, a commodity business.

     Talc is mined, beneficiated and processed at the Company's Barretts
site, located near Dillon, Montana, and is sold worldwide in finely ground
form for paints and coatings, ceramics and polymers applications. Because
of the exceptional chemical purity of the Barretts ore, virtually all of
the automotive catalytic converter ceramic substrates manufactured in the
United States, Japan and Western Europe utilize the Company's Barretts
talc.  

     Limestone and talc are mined, crushed, screened and beneficiated and,
on occasion, subjected to surface chemical modification.

     Lime, a mineral-based product, is sold commercially to the steel and
chemical industries and used as a raw material for the manufacture of PCC
at the Company's Adams, Massachusetts, facility. 

     The Company's net sales of processed mineral products were $106.5
million, $100.7 million and $95.4 million for the years ended December 31,
1997, 1996 and 1995, respectively. See "Item 7--Management's Discussion and
Analysis of Financial Condition and Results of Operations."

     In March 1998, the Company entered into a Memorandum of Understanding
with another company for the sale of its Limestone Midwest business.  Based
at the Port Inland mine in Gulliver, MI, Limestone Midwest is the Company's
only business unit competing for sales of limestone aggregate, a commodity
business.

     The Company's natural mineral products are supported by the Company's
limestone reserves, which the Company believes are strategically located in
the western and eastern parts of the United States, and talc reserves,
which the Company believes are of outstanding quality. The Company
estimates these reserves, at current usage levels, to be from 40 to over 70
years at its limestone production facilities and in excess of 40 years at
its talc production facilities.


Marketing and Sales

     The Company principally relies on its worldwide direct sales force to
market its products. The direct sales force is augmented by worldwide
technical service teams, employees who are familiar with the industries to
which the Company markets its products, and several regional distributors.
The Company's sales force works closely with the Company's technical
service staff to solve technical and other issues faced by the Company's
customers. The Company's technical service staff assists North American
paper producers in their conversion to alkaline papermaking and provides
post-conversion assistance to customers. In addition, the Company's
technical service personnel advise with respect to the use of monolithic
refractory materials and, in many cases, apply the refractory materials to
the customers' furnaces and other vessels pursuant to service agreements.
Continued use of skilled technical service teams is an important component
of the Company's business strategy. 

     The Company works closely with its customers to ensure that the
customers' requirements are satisfied and often trains and supports
customer personnel in the use of the Company's products.  The Company
conducts domestic marketing and sales from its headquarters in New York and
from regional sales offices in the eastern and western United States.  The
Company's international marketing effort is directed from Brussels,
Belgium; 

 5

Tokyo, Japan; and Singapore. The Company believes its refractory
manufacturing facilities are strategically located to satisfy the stringent
delivery requirements of the steel industry. The Company also believes that
its worldwide network of sales personnel and manufacturing facilities
facilitates the international expansion of its satellite PCC operations. 


Raw Materials 

     The Company uses lime in the production of PCC, and is a significant
purchaser of lime in North America.  Generally, lime is purchased from
unaffiliated suppliers located in close geographic proximity to the
Company's satellite PCC plants, pursuant to long-term contracts, and to a
lesser extent, supplied by the Company from its Adams, Massachusetts,
facility.  If there were to be an interruption in the supply of lime from
any particular lime supplier to the Company, the Company believes that it
would be able to obtain suitable lime from alternate sources, but at an
increased cost (resulting primarily from increased transportation costs).
Pursuant to the Company's contracts with its paper mill customers, this
increased cost would be effectively assumed by the host paper mills.
Accordingly, the Company believes that alternative sources of lime will be
available in the event of supply interruptions at effectively the same cost
to the Company. In Europe, supplies of lime suitable for the manufacture of
PCC are generally available but not at prices that are as attractive as
those prevailing in North America. 

     The principal raw materials used in the Company's monolithic
refractories products are refractory-grade magnesia and various forms of
aluminosilicates. The Company also purchases calcium metal, calcium
silicide, graphite, calcium carbide and various alloys for use in the
production of metallurgical wires and uses lime and aluminum in the
production of calcium metal. The Company purchases a significant portion of
its magnesite requirements from sources in the People's Republic of China. 
During 1994, the Ministry of Foreign Trade and Economic Cooperation of the
People's Republic of China instituted a system under which Chinese
exporters must purchase, through competitive bidding, licenses to export
specified commodities, including magnesia.  The exporters holding such
licenses generally attempt to pass the cost of the license fee on to their
customers.  This license fee was increased significantly as of January
1995, resulting in turn in increased worldwide prices for Chinese magnesia. 
The Company had initiated price increases in refractory products and had
located lower-cost alternative sources of supply of magnesia.  However, the
price increases were not sufficient to fully offset the higher cost of
magnesia, and thus far alternative sources of supply of magnesia have been
limited.   Since the second half of 1996, worldwide prices of Chinese
magnesia have decreased from peak prices and appear to have stabilized.

     Except as noted above, the Company believes that it could obtain
adequate supplies from alternate sources in the event of supply
interruptions of its raw material requirements. 

Competition 
     The Company is continually engaged in efforts to develop new products
and technologies and refine existing products and technologies in order to
remain competitive and, in certain circumstances, to position itself as a
market leader. 

     With respect to its PCC products, the Company competes for sales to
the paper industry based in large part upon technological know-how, patents
and processes that allow the Company to deliver PCC that the Company
believes imparts superior brightness and opacity properties to paper on an
economical basis. The Company is the leading manufacturer and supplier of
PCC to the North American paper industry. It competes with certain
companies both in North America and abroad that sell PCC or offer
alternative products for use in paper filling and coating applications. 
Competition with respect to the Company's PCC sales is based upon price,
availability of materials and optical characteristics such as brightness,
opacity and paper strength. 

     With respect to the Company's refractory products, competitive
conditions vary by geographic region. Competition is based upon price, the
performance characteristics of the product (including strength, quality and
consistency and ease of application) and the availability of technical
support. The Company competes with different companies in different
geographic areas and in separate aspects of its product line. 

 6

     The Company competes in sales of its limestone and talc based
primarily upon product quality and the geographic location of the
purchaser. 


Research and Development 

     Many of the Company's product lines are technology-based, and the
Company's business strategy for continued growth in sales and profitability
depends, to a large extent, on the continued success of its research and
development activities. Among the significant achievements of the Company's
research and development effort have been the satellite PCC plant concept,
acid-tolerant PCC, production of PCC crystal morphologies for coating paper
and the SEQUAD(R) sprayer, the KILNTEQ(R) system and numerous new
refractory products.

     The Company maintains its main research facilities in Bethlehem and
Easton, Pennsylvania, with more than 170 employees engaged in research and
development.  It also has smaller research and development facilities in
Finland, Ireland and Japan.  Expertise in inorganic chemistry,
crystallography and structural analysis, fine particle technology and other
aspects of materials science applies to and supports all of the Company's
product lines. 

     For the years ended December 31, 1997, 1996 and 1995, the Company
expended approximately $20.4 million, $19.7 million and $19.7 million,
respectively, on research and development. The Company believes, based upon
its review of publicly available information regarding the reported
research and development spending of certain of its competitors, that its
investment in research and development as a percentage of net sales exceeds
comparable industry norms. The Company's research and development spending
for 1997 approximated 3.4% of net sales.


Patents and Trademarks 

     The Company owns or has the right to use approximately 390 patents and
approximately 700 trademark registrations related to its business. The
Company believes that its rights under its existing patents, patent
applications and trademarks are of value to its operations, but no one
patent, application or trademark is material to the conduct of the
Company's business as a whole.


Insurance

     The Company maintains liability and property insurance and insurance
for business interruption in the event of damage to its production
facilities and certain other insurance covering risks associated with its
business. The Company believes such insurance is adequate for the operation
of its business. From time to time various types of insurance for companies
in the specialty minerals business have been very expensive or, in some
cases, unavailable. There is no assurance that in the future the Company
will be able to maintain the coverage initially obtained or that the
premiums therefore will not increase substantially. 


Employees
 
     At December 31, 1997, the Company employed approximately 2,250
persons, of whom approximately 650 were employed by the Company outside the
United States.   The Company believes its relationships with its employees
are good.

Environmental, Health and Safety Matters

     The Company's operations are subject to federal, state, local and
foreign laws and regulations relating to the environment and health and
safety. Certain of the Company's operations involve and have involved the
use and release of substances that are classified as toxic or hazardous
substances within the meaning of these laws and regulations. Environmental
operating permits are, or may be, required for certain of the Company's
operations and such permits are subject to modification, renewal and
revocation. The Company regularly monitors and reviews its operations,
procedures and policies for compliance with these laws and regulations. The
Company believes its operations are in substantial compliance with these
laws and regulations and that there are no violations which should have a
material effect on the Company. Despite these compliance efforts, some risk
of environmental and other damage is inherent in the operation of the
business of the Company, as it is with other companies engaged in similar
businesses, and there can be no assurance that material damage will not
occur in the future. The cost of compliance with these laws and regulations
is not expected to have a material adverse effect on the Company. However,
future events, such as changes in or modifications of interpretations of
existing laws and regulations or enforcement policies or further
investigation or evaluation of the potential health hazards of certain
products may give rise to additional compliance and other costs that could
have a material adverse effect on the Company. The Company has a right of
indemnification for certain potential environmental, health and safety
liabilities under agreements entered into between the Company and Pfizer
Inc ("Pfizer") or Quigley Company, Inc. ("Quigley"), a wholly-owned
subsidiary of Pfizer, in connection with the reorganization.  See "Certain
Relationships and Related Transactions" in Item 13.


Cautionary Factors That May Affect Future Results

     The disclosure and analysis set forth in this report contains certain
forward-looking statements, particularly statements relating to future
actions, performance or results of current and anticipated products, sales
efforts, expenditures, and financial results.  From time to time, the
Company also provides forward-looking statements in other publicly-released
materials, both written and oral.  Forward-looking statements provide
current expectations or forecasts of future events such as new products,
revenues and financial performance, and are not limited to describing
historical or current facts.  They can be identified by their use of words
such as "plans," "expects," "anticipated," "will" and other words and
phrases of similar meaning.

     Forward-looking statements are necessarily based on assumptions,
estimates and limited information available at the time they are made.  A
broad variety of risks and uncertainties, both known and unknown, as well
as the inaccuracy of assumptions and estimates, can affect the realization
of the expectations or forecasts in these statements.  Consequently, no
forward-looking statement can be guaranteed.  Actual future results may
vary materially.

     The Company undertakes no obligation to update any forward-looking
statements.  You should refer to the Company's subsequent filings under the
Securities Exchange Act of 1934 for further disclosures.

     As permitted by the Private Securities Litigation Reform Act of 1995,
the Company is providing the following cautionary statements which identify
factors that could cause the Company's actual results to differ
materially from historical and expected results.  It is not possible to
foresee or identify all such factors.  You should not consider this list an
exhaustive statement of all potential risks, uncertainties and inaccurate
assumptions.

- --    Historical Growth Rate
      Continuance of the historical growth rate of the Company depends upon
a number of uncertain events, including the outcome of the Company's
strategies of increasing its penetration into geographical markets such as
Asia, Latin America and Europe; increasing its penetration into product
markets such as the market for paper coating pigments and the market for
groundwood paper pigments; increasing sales to existing PCC  customers by
increasing the amount of PCC used in each ton of paper produced; and
developing, introducing and selling new products.   Difficulties, delays or
failures of any of these strategies could cause the future growth rate of
the Company to differ materially from its historical growth rate.

 8

- --   Contract Renewals
     The Company's sales of PCC are predominantly pursuant to long-term
agreements, generally ten  years in length, with paper mills at which the
Company operates satellite PCC plants.  The terms of many of these
agreements have been extended, often in connection with an expansion of the
satellite PCC plant.  To date, the Company's experience with extensions and
renewals of its satellite PCC agreements has been favorable.  There is no
assurance, however, that this will continue to be the case.  Failure of a
number of the Company's customers to renew existing agreements could cause
the future growth rate of the Company to differ materially from its
historical growth rate, and could have a substantial adverse effect on the
Company's results of operations.

 --  Litigation; Environmental Exposures
     The Company's operations are subject to international, federal, state
and local environmental, tax and other laws and regulations, and
potentially to claims for various legal, environmental and tax matters. 
The Company is currently a party to various litigation matters, including
the Eaton litigation which has previously been disclosed in the
Management's Discussion and Analysis sections of the Company's most recent
filings under the Securities Exchange Act of 1934.   While the Company
carries liability insurance which it believes to be appropriate to its
businesses, and has provided reserves for such matters which it believes to
be adequate, an unanticipated liability arising out of such a litigation
matter or a tax or environmental proceeding could have a material adverse
effect on the Company's financial condition or results of operations.

- --   New Products
     The Company is engaged in a continuous effort to develop new products
in all of its product lines.   Difficulties, delays or failures in the
development, testing, production, marketing or sale of such new products
could cause its actual results of operations to differ materially from
expected results.

- --   Competition; Protection of Intellectual Property
     Particularly in its PCC and Refractory product lines, the Company
competes based in part upon proprietary knowledge, both patented and
unpatented.  The Company's ability to achieve anticipated results depends
in part on its ability to defend its intellectual property against
inappropriate disclosure as well as against infringement.  In addition,
development by the Company's competitors of new products or technologies
that are more effective or less expensive than those the Company offers
could have a material adverse effect on the Company's financial condition
or results of operations.

- --   Risks of Doing Business Abroad
     As the Company expands its operations overseas, it faces the increased
risks of doing business abroad, including inflation, fluctuations in
interest rates and currency exchange rates, nationalization, expropriation,
limits on repatriation of funds, unstable governments and legal systems,
and other factors.  Adverse developments in any of these areas could cause
actual results to differ materially from historical and expected results.

- --   Availability of Raw Materials
     The Company's ability to achieve anticipated results depends in part
on having an adequate supply of raw materials for its manufacturing
operations, particularly lime and carbon dioxide  for PCC operations and
magnesia for refractory operations, and on having adequate access to the
ore reserves at its mining operations.  Unanticipated changes in the costs
or availability of such raw materials, or in the Company's ability to have
access to its ore reserves, could adversely affect the Company's results of
operations.

(1) Leased by the Company. The facilities in Cork, Ireland are operated
    pursuant to a 99-year lease, the term of which commenced in 1963.     
    The Company's headquarters and sales offices in New York, New York are
    held under a lease which expires in 2010.
(2) This plant is leased through a joint venture.
(3) This plant is owned through a joint venture.
(4) This plant is leased to another company.
(5) In March 1998, the Company entered into a Memorandum of Understanding
    for the sale of this facility.

 11

          The Company believes that its facilities, which are of varying
ages and are of different construction types, have been satisfactorily
maintained, are in good condition, are suitable for the Company's
operations and generally provide sufficient capacity to meet the Company's
production requirements.  Based on past loss experience, the Company
believes it is adequately insured in respect of these assets, and for
liabilities which are likely to arise from its operations.


Item 3.  Legal Proceedings 

         The Company and its subsidiary, Specialty Minerals Inc., are
defendants in a lawsuit, captioned Eaton Corporation v. Pfizer Inc,
Minerals Technologies Inc. and Specialty Minerals Inc. which was filed on
July 31, 1996 and is pending in the U.S. District Court for the Western
District of Michigan.  The suit alleges that certain materials sold to
Eaton for use in truck transmissions were defective, necessitating repairs
for which Eaton seeks reimbursement.  While all litigation contains an
element of uncertainty, the Company and Specialty Minerals Inc. believe
that they have valid defenses to the claims asserted by Eaton in this
lawsuit, are continuing to vigorously defend all such claims, and believe
that the outcome of this matter will not have a material adverse effect on
the Company's consolidated financial position or results of operations.

         The Company and its subsidiaries are not party to any other
material pending legal proceedings, other than ordinary routine litigation
incidental to their business.  


Item 4.  Submission of Matters to a Vote of Security Holders

         No matters were submitted to a vote of security holders during the
fourth quarter of 1997.

Overview of 1997 and Outlook

In 1997, the Company adhered to its strategy of expanding its Precipitated
Calcium Carbonate ("PCC") product line.  The Company commenced operations
at five new satellite PCC plants in five different countries (Indonesia,
Slovakia, the United States, Finland and South Africa) and signed
agreements for construction of six new satellite plants --four of which are
now under construction.  These satellite PCC plants are located in France,
Germany and the United States, and together have production capacity
equivalent to approximately seven "satellite units."  (A satellite unit is
equivalent to annual production capacity of between 25,000 and 35,000 tons
of PCC.)  The Company has signed three contracts for the use of its
patented acid-tolerant PCC technology.  This will enable the Company to
expand its sales to makers of groundwood paper grades.  In addition, the
Company expanded several satellite plants at various locations around the
world.  As a result, sales of PCC as a percentage of the Company's total
net sales, which were 37.4% in 1992, had risen to 49.8% by 1997.  The
Company expects this trend to continue as sales and volume growth of PCC
continues to outpace such growth in the Processed Minerals and Refractory
product lines.

Presently, the Company operates or has under construction 53 satellite PCC
plants in 14 countries worldwide. The Company is optimistic that volume
growth will continue in 1998. The Company expects additional expansions at
existing satellite PCC plants to occur in 1998 and also expects to sign
contracts for additional satellite PCC plants in the United States and
abroad.

In 1998, the Company plans to continue its focus on the following growth
strategies for the PCC product line:

- --   Continued efforts to increase market penetration in North America,
     Europe, Latin America, the Pacific Rim and elsewhere.
- --   Continued expansions of the capacity of existing satellite PCC plants
     in response to increased demand, which is resulting from either
     increased PCC filler levels in paper or the installation of new paper
     machines.
- --   Continued research and development and marketing efforts of acid-
     tolerant PCC, coating PCC and other products. 

However, there can be no assurance that the Company will achieve success in
implementing any one or more of these strategies.  

The Company's sales of PCC are predominantly pursuant to long-term
agreements, generally ten years in length, with paper mills at which the
Company operates satellite PCC plants.  The terms of many of these
agreements have been extended, often in connection with an expansion of the
satellite PCC plant.  To date, the Company's experience with extensions and
renewals of its satellite PCC agreements has been favorable.  There is no
assurance, however, that these contracts will be renewed prior to or at
their respective expiration dates.

The Company will continue to emphasize specialty products in its Refractory
product lines and commercialize products, processes and equipment through
research and development efforts.  

As the Company continues to expand its operations overseas, it faces
inherent risks of doing business abroad, including exchange rate
fluctuations, nationalization, expropriation, limits on repatriation of
funds and other factors.  In addition, the Company's performance depends to
some extent on that of the industries it serves, particularly the paper,
steel and construction industries.  

 16

The recent exchange rate movements and economic problems in Southeast Asia
are an indication of foreign business risks experienced by multinational
corporations.  However, the Company's Asian operations are a minor part of
its overall business.  In 1997, they represented approximately 7% of total
sales, while Japan and Australia accounted for about 70% of total Asian
sales. 
Continued uncertainties in Thailand, Indonesia and South Korea
could have adverse repercussions in other parts of Asia and conceivably in
Europe and North America.

     Results of Operations 

     Net Sales
     In Millions             1997     Growth     1996     Growth     1995 
                            ------    ------    ------    ------    ------
     Net sales              $602.3     8.3%     $556.0     6.0%     $524.5
     

     Worldwide net sales in 1997 increased 8.3% over the previous year to
$602.3 million.  Higher volumes in the PCC, Processed Minerals, and
Refractory product lines were responsible for the increase in sales growth. 
The stronger U.S. dollar had an unfavorable impact of approximately $11.3
million (or 2 percentage points) on sales growth.   In 1996, worldwide net
sales increased 6.0% over the prior year to $556.0 million.  This increase
was primarily attributable to growth in the PCC and Processed Minerals
product lines.

Worldwide net sales of PCC in 1997 increased 14.0% to $299.9 million from
$263.1 million in the prior year.  This increase was primarily attributable
to the commencement of operations at five new satellite PCC plants, located
in Indonesia, Slovakia, the United States, Finland and South Africa.  In
addition, a full year of operations at several satellite PCC plants that
began operating in 1996 and volume increases generated by the Company's
long-standing satellite PCC plants also contributed to the sales growth in
1997.  Foreign exchange had an unfavorable impact of approximately $4.3
million on sales growth.  PCC sales in 1996 increased 16.1% to $263.1
million from $226.6 million in 1995.  This increase was primarily
attributed to the start-up of operations at six new satellite plants that
began operations during 1996 and expansion of production capacity at
several locations.

Net sales of Processed Minerals increased 5.8% to $106.5 million in 1997
and rose 5.6% to $100.7 million in 1996.  The sales growth in both years
was primarily attributable to higher volumes.

Net sales of Refractory Products in 1997 increased 1.9% to $195.9 million
from $192.2 million in the prior year.  Excluding the impact of foreign
exchange, sales growth was 5.6%.  Strategic replacement of commodity
products with specialty products and systems dramatically increased the
profitability of this product line.  In 1996, net sales of Refractory
Products decreased 5.1% from the prior year while profitability increased
significantly due to continued emphasis on higher margin specialty
products.  The decrease in Refractory product sales was primarily
attributable to volume declines and unfavorable foreign exchange rates.
Net sales in the United States in 1997 increased 8.2% to $414.4 million
from $383.0 million in 1996.  This increase was attributable to the growth
in the PCC and Processed Minerals product lines.  Foreign sales in 1997
increased 8.7% to $187.9 million, primarily as a result of the continued
international expansion of the Company's PCC product line.  In 1996, net
sales in the United States were 6.3% higher than in the prior year due to
growth in the PCC and Processed Minerals product lines.  Foreign sales in
1996 were 5.3% higher than in the prior year, primarily due to the
international expansion of the Company's PCC product line. 



 Operating Costs and Expenses 
 In Millions                   1997     Growth     1996    Growth    1995 
 -----------                  ------    -------   ------   -------  ------
 Cost of goods sold           $424.6     7.1%     $396.3     5.5%   $375.7
 Marketing, distribution 
   and administrative         $ 77.1     6.4%     $ 72.5     2.9%   $ 70.5
 Research and development     $ 20.4     3.3%     $ 19.7     0.4%   $ 19.7

     Cost of goods sold was 70.5% of sales.  This ratio was lower than the
prior year and was primarily attributable to improved profitability in the
Refractory product line.   Cost of goods sold in 1996 was 71.3% of sales
which was slightly lower than the prior year. This was also attributable to
the improved profitability of the Refractory product lines.

Marketing, distribution and administrative costs increased 6.4% to $77.1
million and were 12.8% of sales, a slight reduction  from the 1996 ratio.  
In 1997, the Company recorded a $1.6 million provision for loss as
guarantor of indebtedness of a company which was the subject of an
involuntary bankruptcy petition under Chapter 7 of the U.S. Bankruptcy
Code.  In addition, the Company recognized a gain of approximately $1.4
million related to the sale of property in Japan.  Such non-recurring items
are included in marketing, distribution and administrative expenses.  In
1996, marketing, distribution and administrative costs increased 2.9% to
$72.5 million and were 13.0% of sales.


 17


Research and development expenses during 1997 increased 3.3% to $20.4
million and represented 3.4% of sales, a slight reduction from the 1996
ratio. This reduction reflects a more efficient use of resources due to the
increasing worldwide infrastructure which allows the Company to support
trials and new plants at a lower cost while continuing its commitment to
research, particularly in the PCC product line. In 1996 and 1995 research
and development spending was $19.7 million.

 Income from Operations
 In Millions                   1997     Growth     1996    Growth    1995

 Income from operations       $80.2      19.0%    $67.4     14.9%   $58.7

     Income from operations in 1997 increased 19.0% to $80.2 million from
$67.4 million in 1996.  This increase was due primarily to solid growth in
the PCC product line and improved profitability in the Refractory product
lines.  This profitability occurred because of the successful
implementation of the Company's strategy of introducing high-value,
innovative products.  Operating profits were negatively impacted by startup
costs associated with the five new satellite PCC plants and some weakness
in the Processed Minerals product line, specifically in talc products.  In
1996, income from operations rose 14.9% to $67.4 million from $58.7 million
in 1995.  This growth was achieved through higher sales volumes in the PCC
product line, greater profitability in the Refractory product lines and an
overall decrease in costs and expenses.  Operating profits in 1996 were
negatively impacted by the higher cost of magnesia and startup costs
associated with the six new satellite PCC plants.

 Non-Operating Deductions
 In Millions                   1997     Growth     1996    Growth    1995

     Non-operating deductions in 1997 increased due to foreign exchange
losses and higher net interest expense which resulted from a reduction in
capitalized interest costs.  These deductions were partially offset by
higher interest income.  The  reduction in capitalized interest was due to
lower levels of capital spending in the first nine months of 1997.  Gross
interest expense decreased 2.6% from the prior year to $8.2 million.  The
foreign exchange losses were approximately $1.7 million and occurred
primarily in the joint ventures in Thailand, Indonesia and Korea.  Interest
expense increased in 1996 primarily as a result of higher interest costs
associated with additional borrowings.  Interest income and other income
were significantly higher in 1995 due to higher levels of cash-on-hand and
foreign exchange gains, respectively.

 Provision for Taxes on Income

     The effective tax rate was 32.0% in 1997.  In 1996, higher depletion
and utilization of foreign tax credits decreased the effective tax rate to
31.1%; down 1.4 percentage points from the effective tax rate in 1995.

     Although the Company's consolidated joint ventures reflected
profitable income from operations, they reported a net loss in 1997 due
primarily to the aforementioned foreign exchange losses in Thailand,
Indonesia and Korea.  In 1996, foreign exchange had a minimal impact on
these joint ventures.

     Net income increased 16.7% in 1997 to $50.3 million.  In 1996, net
income increased 9.0% to $43.1 million. 

Liquidity and Capital Resources

     The Company's financial position remained strong during 1997.  Cash
flows in 1997 were provided principally from operations and were primarily
applied to fund $77.3 million of capital expenditures.  In addition, the
Company remitted its required per annum principal payment of $13 million
under the Company's Guarantied Senior Notes due June 11, 2000 and reduced
its short-term debt.  The Company also retired $7.3 million of Industrial
Development Bonds due 2009.  Cash provided from operating activities was
the primary source of liquidity and amounted to $120.6 million in 1997,
$69.9 million in 1996 and $58.3 million in 1995.

The Variable Fixed Rate Industrial Development Revenue Bonds due April 1,
2012 are tax-exempt 15-year instruments and were issued on April 1, 1997 to
finance the construction of a PCC plant in Jackson, Alabama.  The bonds
bear interest at either a variable rate or fixed rate, at the option of the
Company.  Interest is payable semi-annually under the fixed rate option and
monthly under the variable rate option.  The Company has selected the
variable rate option on these borrowings and the average interest rate was
approximately 4%.

On August 4, 1997, the Company redeemed $1,455,000 of the Variable/Fixed
Rate Industrial Development Revenue Bonds due April 1, 2012.  This
represented the unused portion of the original bond issuance proceeds
received on April 1, 1997 to finance the construction of a PCC plant in
Jackson, Alabama.

The Variable/Fixed Rate Industrial Development Revenue Bonds due August 1,
2012 are tax-exempt 15-year instruments that were issued on August 1, 1997
to finance the construction of a PCC plant in North America.  The bonds
bear interest at either a variable rate or fixed rate, at the option of the
Company.  Interest is payable semi-annually under the fixed rate option and
monthly under the variable rate option.  The Company has selected the
variable rate option on these borrowings and the average interest rate was
approximately 4%.

On July 24, 1996, through a private placement, the Company issued $50
million of 7.49% Guaranteed Senior Notes due July 24, 2006.  The proceeds
from the sale of the notes were used to refinance a portion of the short-
term commercial bank debt outstanding.  No required principal payments are
due until July 24, 2006.  Interest on the notes is payable semi-annually.

On February 26, 1998, the Company's Board of Directors authorized a $150
million stock repurchase program.  The stock will be purchased on the open
market from time to time.

In March 1998, the Company entered into a Memorandum of Understanding with
another company for the sale of its Limestone Midwest business.  Based at
the Port Inland mine in Gulliver, MI, Limestone Midwest is the Company's
only business unit competing for sales of limestone aggregate, a commodity
business.  Sales for Limestone Midwest were approximately $20.8 million in
1997.  The Company does not expect any significant gain or loss to result
from the sale of these operations.

The Company has also entered into a long-term lease of its Pima County,
Arizona limestone facility with the Georgia Marble Company.  Sales for this
facility in 1997 were approximately $1.5 million.

The Company has available approximately $110 million in uncommitted, short-
term bank credit lines, none of which were in use at December 31, 1997.  
The 1996 interest rate on the $12.0 million borrowed from these short-term
bank credit lines was 6.93%.  The Company anticipates that capital
expenditures for 1998 will be approximately $90 million, principally
related to the construction of satellite PCC plants, expansion projects at
existing satellite PCC plants and other opportunities that meet the
strategic growth objectives of the Company.   The Company expects to meet
its long-term financing requirements from internally generated funds, the
aforementioned uncommitted bank credit lines and, where appropriate,
project financing of certain satellite plants.

     Prospective Information and Factors That May Affect Future Results
     The Securities and Exchange Commission encourages companies to
disclose forward-looking information so that investors can better
understand a company's future prospects and make informed investment
decisions.  This annual report contains such forward-looking statements
that set out anticipated results based on management's plans and
assumptions.  Words such as "anticipate," "estimate," "expects,"
"projects," and words and terms of similar substance used in connection
with any discussion of future operating or financial performance identify
these forward-looking statements.

 19

The Company cannot guarantee that any forward-looking statement will be
realized, although it believes it has been prudent in its plans and
assumptions.  Achievement of future results are subject to risks,
uncertainties and inaccurate assumptions.  Should known or unknown risks or
uncertainties materialize, or should underlying assumptions prove
inaccurate, actual results could vary materially from those anticipated,
estimated or projected.  Investors should bear this in mind as they
consider forward-looking statements.  Discussion of certain risks,
uncertainties and assumptions follow and are discussed under the heading
entitled "Cautionary Factors That May Affect Future Results" in Item 1.

     Inflation
     Historically, inflation has not had a material adverse impact on the
Company.  The contracts pursuant to which the Company constructs and
operates its satellite PCC plants generally adjust pricing to reflect
increases in costs resulting from inflation.

     Recently Issued Accounting Standards
     In the fourth quarter of 1997, the Company adopted the provisions of
Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per
Share," which established standards for computing and presenting earnings
per share (EPS).  The Statement simplifies the standards for computing EPS,
replaces the presentation of primary EPS with a presentation of basic EPS
and requires dual presentation of basic and diluted EPS on the face of the
income statement.  This Statement required restatement of all prior-period
EPS data presented and did not have a material impact on previously
reported EPS data.  

In 1998, the Company will adopt SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information."  The Company does not expect adoption of these
standards to have a material impact on its Consolidated Financial
Statements.

     Year 2000 Conversion
     Management has initiated an enterprise-wide program to improve the
capability of the current information systems and to prepare the Company's
computer systems and applications for the year 2000.  The Company is
presently in the midst of installing systems which are year 2000-compliant
and will replace the majority of the legacy information technology systems
and applications.  It is anticipated that such systems will be installed by
the middle of 1999.  The Company does not expect the total cost of the year
2000 conversion to have a material adverse effect on the Company's future
results of operations and financial condition.

        MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

             Summary of Significant Accounting Policies 

     Basis of Presentation 
The accompanying consolidated financial statements include the accounts of
Minerals Technologies Inc. (the "Company") and its wholly and majority
owned subsidiaries.  All intercompany balances and transactions have been
eliminated in consolidation.  

     Use of Estimates
     The Company employs accounting policies that are in accordance with
generally accepted accounting principles in the United States and require
management to make estimates and assumptions relating to the reporting of
assets and liabilities and the disclosure of contingent liabilities at the
date of the financial statements.  Actual results could differ from those
estimates.

     Business
The Company is a resource - and technology-based company that develops,
produces and markets on a worldwide basis a broad range of specialty
mineral, mineral-based and synthetic mineral products.  The Company's
products are used in manufacturing processes of the paper and steel
industries, as well as by the building materials, polymers, ceramics,
paints and coatings, glass and other manufacturing industries.

     Cash Equivalents
The Company considers all highly liquid investments with maturities of
three months or less at the date of purchase to be cash equivalents.  Cash
equivalents amounted to $8.6 million and $6.0 million at December 31, 1997
and 1996, respectively.

     Inventories 
Inventories are valued at the lower of cost or market. Cost is determined
by the first-in, first-out (FIFO) method. 

     Property, Plant and Equipment 
Property, plant and equipment are recorded at cost.  Significant
improvements are capitalized. In general, the straight line method of
depreciation is used for financial reporting purposes and accelerated
methods are used for U.S. and certain foreign tax reporting purposes.  The
annual rates of depreciation are 4%-5% for buildings, 8%-12% for machinery
and equipment and 8%-12% for furniture and fixtures.

Depletion of the mineral and quarry properties is provided on a
unit-of-extraction basis as the related materials are mined for financial
reporting purposes and on a percentage depletion basis for tax purposes. 

Mining costs associated with waste gravel and rock removal in excess of the
expected average life of mine stripping ratio are deferred.  These costs
are charged to production on a unit-of-production basis when the ratio of
waste to ore mined is less than the average life of mine stripping ratio.

    Foreign Currency 
The assets and liabilities of most of the Company's international
subsidiaries are translated into U.S. dollars using current exchange rates
at the respective balance sheet date.  The resulting translation
adjustments are recorded in the currency translation adjustment account in
shareholders' equity.  Income statement items are generally translated at
average exchange rates prevailing during the period.  Other foreign
currency gains and losses are included in net income.

     International subsidiaries operating in highly inflationary economies
translate nonmonetary assets at historical rates, while net monetary assets
are translated at current rates, with the resulting translation adjustments
included in net income. 

     Income Taxes 
     Income taxes are provided for based on the asset and liability method
of accounting pursuant to Statement of Financial Accounting Standards No.
109, "Accounting for Income Taxes" ("SFAS 109").  Under SFAS 109, deferred
tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective
tax bases. Deferred tax assets and liabilities are measured using enacted
tax rates in effect for the year in which those temporary differences are
expected to be recovered or settled. Under SFAS 109, the effect on deferred
tax assets and liabilities of a change in tax rates is recognized in income
in the period that includes the enactment date.

           MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
               NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The accompanying financial statements generally do not include a provision
for U.S. income taxes on international subsidiaries' unremitted earnings
which, for the most part, are expected to be reinvested overseas. 

     Stock-Based Compensation
     The Company has adopted Statement of Financial Accounting Standards
No. 123, "Accounting for Stock Based Compensation" ("SFAS 123"), which
requires expanded disclosures of stock-based compensation arrangements with
employees.  SFAS No. 123 establishes an alternative method of accounting
for stock-based compensation awarded to employees which provides for the
recognition of compensation cost to be measured based on the fair value of
the equity instrument awarded.  The Company, however, has elected to
continue to recognize compensation cost based on the intrinsic value of the
equity instrument awarded as promulgated in Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees."  The Company
has disclosed below under "Capital Stock -- Stock and Incentive Plan" the
pro forma effect of the fair value method on net income and earnings per
share.

     Postretirement Benefits
The Company accrues the cost of postretirement benefits during the
employee's active working career as required by Statement of Financial
Accounting Standards No. 106, "Employers' Accounting for Postretirement
Benefits other than Pensions" ("SFAS 106").

     Earnings Per Share
     The Company has adopted Statement of Financial Accounting Standards
(SFAS) No. 128, "Earnings per Share," which established standards for
computing and presenting earnings per share (EPS).  The statement
simplifies the standards for computing EPS, replaces the presentation of
primary EPS with a presentation of basic EPS and requires a dual
presentation of basic and diluted EPS on the face of the income statement.

     Basic EPS are based upon the weighted average number of common shares
outstanding during the period. 

     Diluted EPS are based upon the weighted average number of common
shares outstanding during the period assuming the issuance of common shares
for all dilutive potential common shares outstanding.

Income Taxes

     Income before provision for taxes, by domestic and foreign source is
as follows: 

  Thousands of Dollars                1997        1996       1995

The major elements contributing to the difference between the U.S. federal
statutory tax rate and the consolidated effective tax rate are as follows:

A valuation allowance for deferred tax assets has not been recorded since
management believes it is more likely than not that the existing net
deductible temporary differences will reverse during periods in which the
Company generates net taxable income.

Net cash paid for income taxes was $14.2 million, $15.4 million and $11.0
million for the years ended December 31, 1997, 1996 and 1995, respectively.

Foreign Operations

     The Company has not provided for U.S. federal and foreign withholding
taxes on $57.0 million of foreign subsidiaries' undistributed earnings as
of December 31, 1997 because such earnings, for the most part, are intended
to be reinvested overseas.  To the extent the parent  company has received
foreign earnings as dividends, the foreign taxes paid on those earnings
have generated tax credits which have substantially offset related U.S.
income taxes.  On repatriation, certain foreign countries impose
withholding taxes.  The amount of withholding tax that would be payable on
remittance of the entire amount of undistributed earnings would approximate
$1.7 million.

Net foreign currency exchange gains (losses), included in other income
(deductions) in the Consolidated Statement of Income, were $(1,721,000),
$296,000 and $1,620,000 for the years ended December 31, 1997, 1996 and
1995, respectively.

Financial Instruments and Concentrations of Credit Risk

The following methods and assumptions were used to estimate the fair value
of each class of financial instrument:

Cash and cash equivalents, accounts receivable and payable, and accrued
liabilities:
The carrying amounts approximate fair value because of the short maturity
of these instruments.

Available-for-sale securities:
The available-for-sale securities are presented in accordance with SFAS No.
115, "Accounting for Certain Investments in Debt and Equity Securities." 
The fair values are based on quoted market prices and are as follows:

                         1997                     1996

of Dollars      Value    Holding Gains  
- ----------     ------  ----------------
Common Stock     $427              $231

The unrealized holding gains, net of taxes, were $113,000, $163,000 and
$111,000, respectively, at December 31, 1997, 1996 and 1995 and are
included as a separate component of shareholders' equity.

Short-term debt and other liabilities:
The carrying amounts of short-term debt and other liabilities approximate
fair value because of the short maturity of these instruments.

Long-term debt:
The fair value of the long-term debt of the Company is estimated based on
the quoted market prices for that debt or similar debt which approximates
the carrying amount.
Forward exchange contracts:
The fair value of forward exchange contracts (used for hedging purposes) is
estimated by obtaining quotes from brokers.

The Company enters into forward exchange contracts to hedge foreign
currency transactions on a continuing basis for periods consistent with its
committed exposures. It does not engage in speculation. The effect of this
practice is to delay on a rolling basis the impact of foreign exchange rate
movements on the Company's operating results. The Company's foreign
exchange contracts do not subject the Company to risk from exchange rate
movements because gains and losses on these contracts offset losses and
gains on the assets, liabilities and transactions being hedged.  There were
no open forward exchange contracts outstanding at December 31, 1997.   At
December 31, 1996, the Company had open forward exchange contracts to sell
$1.1 million of foreign currencies.  The difference between these contract
values and the fair value of these instruments was not significant  at
December 31, 1996. 

Credit risk:
Substantially all of the Company's accounts receivable are due from
companies in the paper, construction and steel industries. Credit risk
results from the possibility that a loss may occur from the failure of
another party to perform according to the terms of the contract. The
Company regularly monitors the credit risk exposures and takes steps to
mitigate the likelihood of these exposures resulting in actual loss. 

The Company's extension of credit is based on an evaluation of the
customer's financial condition and collateral is not required. Credit
losses are provided for in the financial statements and consistently have
been within management's expectations.

Benefits under defined benefit plans are generally based on years of
service and the employee's career earnings. Employees become fully vested
after five years. 

The Company's funding policy for U.S. plans generally is to contribute
annually into trust funds at a rate that is intended to remain at a level
percentage of compensation for covered employees. The funding policy for
the international plans conforms to local governmental and tax
requirements.  The plans' assets are invested primarily in stocks and
bonds. 

   Savings and Investment Plans
   The Company maintains a voluntary Savings and Investment Plan for most
non-union employees in the U.S. Within prescribed limits, the Company bases
its contribution to the Plan on employee contributions. The Company
contributions amounted to $3.1 million, $3.0 million and $3.0 million for
the years ended December 31, 1997, 1996 and 1995, respectively.

   Postretirement Benefits
   The Company provides postretirement health care and life insurance
benefits for substantially all of its U.S. retired employees. Employees are
generally eligible for benefits upon retirement and completion of a
specified number of years of creditable service. The Company does not
pre-fund these benefits and has the right to modify or terminate the plan
in the future.

The components of the net periodic postretirement benefit cost are as

The weighted average discount rate used in determining the accumulated
postretirement benefit obligation was 7.25% and 7.75% at December 31, 1997
and 1996, respectively.  Compensation levels are assumed to increase at a
rate of 4.25% and 4.75%, respectively, at December 31, 1997 and 1996.

For measurement purposes, a health care cost trend rate of approximately
10.5% for pre-age-65 benefits and 8.5% for post-age-65 benefits was used. 
This trend rate will decrease to 5.3% in the year 2005 and thereafter.

A 1% increase in this annual trend rate would have increased the
accumulated postretirement benefit obligation at December 31, 1997  by
approximately $110,000 and the aggregate of the service and interest cost
components of net periodic postretirement benefit cost for the year then
ended by approximately $9,000.  

Leases

   Rent expense for the years ended December 31, 1997, 1996 and 1995,
amounted to approximately $4.2 million, $4.2 million and $4.3 million,
respectively. Total future minimum rental commitments under all
noncancellable leases for the years 1998 through 2002 and thereafter are
approximately $2.1 million, $2.0 million, $1.8 million, $1.8 million, $1.5
million and $16.7 million, respectively.

The Company has entered into a long-term direct financing lease of its Pima
County, Arizona limestone facility with another company.  Total future
minimum payments to be received under direct financing leases for the years
1998 through 2002 and thereafter are approximately $0.1 million, $0.2
million, $0.2 million, $0.2 million, $0.2 million and $3.3 million,
respectively.

Litigation

   Under the terms of certain agreements entered into in connection with
the reorganization prior to the initial public offering of the Company's
common stock in October 1992,  Pfizer and its wholly owned subsidiary,
Quigley Company, Inc. ("Quigley") agreed to indemnify the Company against
certain liabilities being retained by Pfizer and its subsidiaries
including, but not limited to, pending lawsuits and claims and any lawsuits
or claims brought at any time in the future alleging damages or injury from
the use, handling of or exposure to any product sold by Pfizer's specialty
minerals business prior to the closing of the initial public offering. 

   Pfizer and Quigley also agreed to indemnify the Company against any
liability arising from on-site remedial waste site claims and for other
claims that may be made in the future with respect to wastes disposed of
prior to the closing of the initial public offering.  Further, Pfizer and
Quigley agreed to indemnify the Company for 50% of the liabilities in
excess of $1 million up to $10 million that may arise or accrue within ten
years after the closing of the initial public offering with respect to
remediation of on-site conditions existing at the time of the closing of
the initial public offering. The Company will be responsible for the first
$1 million of such liabilities, 50% of such liabilities in excess of $1
million up to $10 million, and all such liabilities in excess of $10
million. Further, Pfizer and Quigley agreed to indemnify the Company for
non-remedial environmental claims resulting from activities or conditions
occurring or existing prior to the closing of the initial public offering
that are in excess of $10,000 and that were received within two years after
the closing of the initial public offering, exclusive of compliance costs
and consequential damages.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


The transfer by Quigley of certain real property in New Jersey to the
Company pursuant to the reorganization, including the former Quigley
facility in Old Bridge, triggered certain obligations under the New Jersey
Environmental Cleanup Responsibility Act ("ECRA").  Quigley retained
liability for compliance with ECRA including the assessment and, if
necessary, remediation of the Old Bridge property.  Quigley's obligations
under ECRA are embodied in an Administrative Consent Order with the New
Jersey Department of Environmental Protection and Energy ("NJDEPE") that
requires Quigley to perform any necessary remediation and to provide
financial assurance of its ability to cover the costs of remediation as
estimated by NJDEPE with no obligation to the Company.

The Company and its subsidiary, Specialty Minerals Inc., are defendants in
a lawsuit, captioned Eaton Corporation v. Pfizer Inc, Minerals Technologies
Inc. and Specialty Minerals Inc. which was filed on July 31, 1996 and is
pending in the U.S. District Court for the Western District of Michigan. 
The suit alleges that certain materials sold to Eaton for use in truck
transmissions were defective, necessitating repairs for which Eaton seeks
reimbursement.  While all litigation contains an element of uncertainty,
the Company and Specialty Minerals Inc. believe that they have valid
defenses to the claims asserted by Eaton in this lawsuit, are continuing to
vigorously defend all such claims, and believe that the outcome of this
matter will not have a material adverse effect on the Company's
consolidated financial position or results of operations.


Capital Stock

   The Company's authorized capital stock consists of 100 million shares of
common stock, par value $.10 per share, of which  22,540,385 shares and
22,599,859 shares were outstanding at December 31, 1997 and 1996,
respectively, and 1 million shares of preferred stock, none of which were
issued and outstanding.

   Cash Dividends
   Cash dividends of $2.3 million or $.10 per common share were paid during
1997.  In January 1998, a cash dividend of approximately $565,000 or $ .025
per share, was declared, payable in the first quarter of 1998.

   Preferred Stock Purchase Rights
   Under the Company's Preferred Stock Purchase Rights Plan, each share of
the Company's common stock carries with it one preferred stock purchase
right.  Subject to the terms and conditions set forth in the plan, the
rights will become exercisable if a person or group acquires beneficial
ownership of 15% or more of the Company's common stock or announces a
tender or exchange offer which would result in the acquisition of 30% or
more thereof.  If the rights become exercisable, separate certificates
evidencing the rights will be distributed, and each right will entitle the
holder to purchase from the Company a new series of preferred stock,
designated as Series A Junior Preferred Stock, at a predefined price.  The
rights also entitle the holder to purchase shares in a change-of-control
situation.  The preferred stock, in addition to a preferred dividend and
liquidation right, will entitle the holder to vote on a pro rata basis with
the Company's common stock.

The rights are redeemable by the Company at a fixed price until 10 days, or
longer as determined by the Board, after certain defined events or at any
time prior to the expiration of the rights on October 26, 2002 if such
events do not occur.

   Stock and Incentive Plan
   The Company has adopted a Stock and Incentive Plan (the "Plan") which
provides for grants of incentive and nonqualified stock options, stock
appreciation rights, stock awards or performance unit awards.  The Plan is
administered by the Compensation Committee of the Board of Directors. Stock
options granted under the Plan have a term not in excess of ten years. The
exercise price for stock options will not be less than the fair market
value of the common stock on the date of the grant, and each award of stock
options will vest ratably over a specified period, generally three years.  

In 1995, the Shareholders approved an amendment to the Plan to increase the
number of shares of common stock available under the Plan by an additional
one million.

In 1996, the Company adopted the disclosure provisions of SFAS No. 123,
"Accounting for Stock Based Compensation."  There were no stock options
granted in 1997.  The weighted-average fair value per option at the date of
grant for options granted during 1996 was $9.64.  The fair value was
estimated using the Black-Scholes option pricing model, modified for
dividends, and the following weighted-average assumptions:

Expected life (years)                      5
Interest rate                            6.20%
Volatility                              21.53%
Expected dividend yield                  0.33%

Pro forma net income and earnings per share reflecting compensation cost
for the fair value of stock options awarded in 1996 were as follows:

Independent Auditors' Report

   The Board of Directors and Shareholders
   Minerals Technologies Inc.:

     We have audited the accompanying consolidated balance sheet of
Minerals Technologies Inc. and subsidiary companies as of December 31, 1997
and 1996 and the related consolidated statements of income, shareholders'
equity and cash flows for each of the years in the three-year period ended
December 31, 1997.  These consolidated financial statements are the
responsibility of the Company's management.  Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated
financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall consolidated financial statement presentation.  We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
Minerals Technologies Inc. and subsidiary companies as of December 31, 1997
and 1996 and the results of their operations and their cash flows for each
of the years in the three-year period ended December 31, 1997 in conformity
with generally accepted accounting principles.

Management's Responsibility for Financial Statements and System of Internal
Control


   The consolidated financial statements and all related financial
information herein are the responsibility of the Company's management.  The
financial statements, which include amounts based on judgments, have been
prepared in accordance with generally accepted accounting principles. 
Other financial information in the annual report is consistent with that in
the financial statements.

The Company maintains a system of internal control over financial reporting
which it believes provides reasonable assurance that transactions are
executed in accordance with management's authorization and are properly
recorded, that assets are safeguarded, and that accountability for assets
is maintained.  Even an effective internal control system, no matter how
well designed, has inherent limitations and, therefore, can provide only
reasonable assurance with respect to financial statement preparation.  The
system of internal control is characterized by a control-oriented
environment within the Company which includes written policies and
procedures, careful selection and training of personnel, and audits by a
professional staff of internal auditors.

The Company's independent accountants have audited and reported on the
Company's consolidated financial statements.  Their audits were performed
in accordance with generally accepted auditing standards.

The Audit Committee of the Board of Directors is composed solely of outside
directors.  The Audit Committee meets periodically with our independent
auditors, internal auditors and management to review accounting, auditing,
internal control and financial reporting matters.  Recommendations made by
the independent auditors and the Company's internal auditors are considered
and appropriate action is taken with respect to these recommendations. 
Both our independent auditors and internal auditors have free access to the
Audit Committee.
