Item 5.04

Temporary Suspension of Trading Under Registrant's Employee Benefit Plans.

Effective September 14, 2007, the Minerals Technologies Inc. Savings and Investment Plan (the "Plan") will be transferring recordkeeping and trustee services to New York Life Trust Company. As a result of this change, participants in the Plan will temporarily be unable to direct or diversify investments in their individual accounts, obtain loans from the Plan, or obtain withdrawals or distributions from the Plan. This period, during which participants will be unable to exercise their rights otherwise available under the Plan, is called a "blackout period." Minerals Technologies Inc.'s common stock, par value $0.10 per share, is subject to the blackout period. The blackout period for the Plan began on September 7, 2007, at 4:00 p.m. Eastern time, and is expected to end during the week of September 16, 2007. During this time, participants can determine whether the blackout period has ended, or inquire about the blackout period, by contacting a New York Life Participant Service Center Representative at 1-800-294-3575. Participant Service Center Representatives are available from 9:00 a.m. to 8:00 p.m. Eastern time on any New York Stock Exchange business day. Participants may also forward correspondence relating to the foregoing to New York Life Retirement Plan Services, P.O. Box 447, Norwood, MA 02062-0447.
