Re: IMSCO Technologies, Inc.
    Registration Statement on Form S-8

Gentlemen:

We have acted as  counsel  to you (the  "Corporation")  in  connection  with the
preparation and filing of the above-captioned Registration Statement on Form S-8
(the  "Registration  Statement")  under the  Securities Act of 1933, as amended,
relating to the  proposed  issuance  of up to  1,500,000  shares (the  "Original
Shares")  of the  Corporation's  Common  Stock,  par value  $.001 per share (the
"Common  Stock"),  which may be issued  pursuant to the 1996 Employee  Incentive
Stock Option Plan of the  Corporation  (the "Plan") and such  additional  shares
(the  "Additional  Shares")  as  may be  issued  pursuant  to  the  antidilution
provisions  of the Plan.  You have  represented,  and we have  expressly  relied
thereon,  that no Common  Stock or options to  purchase  Common  Stock have been
issued  under the Plan.  The  Original  Shares  and the  Additional  Shares  are
hereinafter referred to together as the "Shares". This opinion letter is Exhibit
5.1 to the Registration Statement.

We have examined  copies of the Certificate of  Incorporation  and the Bylaws of
the Corporation,  as amended to date, the Registration  Statement (including the
exhibits  thereto),  the Plan,  the minutes of various  meetings of the Board of
Directors of the Corporation,  and the originals,  copies or certified copies of
all such records of the Corporation,  and all such  agreements,  certificates of
public  officials,   certificates  of  officers  and   representatives   of  the
Corporation,  or  others,  and  such  other  documents,   papers,  statutes  and
authorities  as we have  deemed  necessary  to form  the  basis  of the  opinion
hereinafter expressed.  In such examination,  we have assumed the genuineness of
signatures and the conformity to original documents of the documents supplied to
us as copies. As to various questions of fact material to such opinion,  we have
relied upon  statements  and  certificates  of officers of the  Corporation  and
others.

Attorneys  involved in the  preparation of this opinion are admitted to practice
law in the State of New York and we do not  purport to be experts on, or express
any opinion herein  concerning,  any law other than the laws of the State of New
York,  the  federal  laws of the  United  States  of  America  and  the  General
Corporation Law of the State of Delaware.

Based upon and subject to the  foregoing,  we are of the opinion that all of the
Shares  have been duly  authorized  and,  when  issued  under the  circumstances
contemplated in the Registration Statement and the Plan, will be validly issued,
fully paid and nonassessable.

We hereby  consent  to your  filing a copy of this  opinion as an exhibit to the
Registration  Statement.  In giving such consent, we do not admit hereby that we
come within the category of persons whose consent is required under Section 7 of
the  Securities  Act of 1933, as amended,  or the rules and  regulations  of the
Securities and Exchange Commission thereunder.

Very truly yours,

EPSTEIN BECKER & GREEN, P.C.
