Dear Fellow Stockholder:

    You are cordially invited to attend the 2003 Annual Meeting of Stockholders
of Minerals Technologies Inc., which will be held on Thursday, May 22, 2003, at
2:00 p.m., in the J. P. Morgan Chase & Co. Building, 11th floor, Room C, 270
Park Avenue (between 47th and 48th Streets), New York, New York 10017.

    At this year's meeting, you will be asked to consider and to vote upon the
election of four directors, including myself. Your Board of Directors
unanimously recommends that you vote FOR the nominees.

    You will also be asked to ratify the appointment of KPMG LLP as our
independent auditors for the 2003 fiscal year. The Board continues to be pleased
with the services KPMG LLP has rendered to Minerals Technologies, and
unanimously recommends that you vote FOR this proposal.

    The two items upon which you will be asked to vote are discussed more fully
in the Proxy Statement. I urge you to read the Proxy Statement completely and
carefully so that you can vote your interests on an informed basis.

    Your vote is important! Whether or not you plan to attend the meeting, and
regardless of the number of shares you own, your representation and vote are
very important and you should vote your shares. Therefore, I urge you to
complete, sign, date and return the enclosed proxy card promptly in the
accompanying postage prepaid envelope. All shareholders of record, and many
street name holders, may also vote by internet, or by touchtone telephone from
the United States and Canada, using the instructions on the proxy card. If you
return a signed proxy without marking it, it will be voted in accordance with
management's recommendations. You may, of course, attend the Annual Meeting and
vote in person, even if you have previously submitted a proxy.

                                                      Sincerely,

                                                      Paul R. Saueracker

    Minerals Technologies Inc. is sending this Proxy Statement and form of proxy

Room C, 270 Park Avenue (between 47th and 48th Streets), New York, New York

even if you do not attend the meeting, your shares will be counted as present at
the meeting and voted as you direct.

    At the Annual Meeting, stockholders will vote on two questions: the election
of directors, and ratification of the appointment of auditors. The Board
unanimously recommends that you vote FOR each of the nominees for director,
Kristina M. Johnson, Michael F. Pasquale, John T. Reid and Paul R. Saueracker,

    Holders of record of common stock of Minerals Technologies at the close of

Company owned 5.5%, and Wellington Management Company, LLP owned 5.3%, of our
common stock. No other person owned of record, or, to our knowledge, owned
beneficially, more than 5% of our common stock.

    If you submit a proxy, you can revoke it at any time before it is voted by
submitting a written revocation or a new proxy, or by voting in person at the
Annual Meeting.

                        ITEM 1 -- ELECTION OF DIRECTORS

    The Board of Directors is divided into three classes. One class is elected
each year for a three-year term. This year the Board has nominated Kristina M.
Johnson, Michael F. Pasquale, John T. Reid and Paul R. Saueracker, who are now
directors of Minerals Technologies, to serve for a three-year term expiring at
the Annual Meeting of Stockholders to be held in 2006.

    The Board expects that the nominees will be available for election. If one
or more nominees should become unavailable, your proxy would be voted for a
nominee or nominees who would be designated by the Board, unless the Board
reduces the number of directors.

    THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR ELECTION OF EACH OF
KRISTINA M. JOHNSON, MICHAEL F. PASQUALE, JOHN T. REID AND PAUL R. SAUERACKER.

                BOARD OF DIRECTORS, COMMITTEES AND COMPENSATION

    The Board of Directors met eight times in 2002. Each of the directors, with
the exception of Mr. Steere, attended 75 percent or more of the meetings of the
Board and committees on which he or she served in 2002.

THE COMPENSATION AND NOMINATING COMMITTEE

    The Compensation and Nominating Committee consists of Mr. Curcio (Chair),
Mr. Meister and Mr. Steere, who are not employees of Minerals Technologies. The
Compensation and Nominating Committee met six times in 2002.

    The Board of Directors has reviewed, assessed the adequacy of and approved a
formal written charter for the Compensation and Nominating Committee.

    The primary functions of the Compensation and Nominating Committee are:

  To participate in the development of our compensation and benefits policies;

  To establish, and from time to time vary, the salaries and other compensation
  of our employee-directors and other elected officers;

  To participate in top-level management succession planning; and

  To bring forward the names of suitable candidates for election to the Board.

THE AUDIT COMMITTEE

    The Audit Committee consists of Mr. Pasquale (Chair), Mr. Dunham, Mr. Golub
and Dr. Johnson, who are not employees of Minerals Technologies. The Board of
Directors has determined that each of the members of the Audit Committee is
independent and financially literate in accordance with the rules of the New
York Stock Exchange, as well as being independent under the rules of the
Securities and Exchange Commission. The Board has also determined that
Mr. Pasquale, Chair of the Audit Committee, has 'financial expertise' for
purposes of the rules of the New York Stock Exchange.

    The Audit Committee met eight times in 2002.

    The Board of Directors has reviewed, assessed the adequacy of and approved a
formal written charter for the Audit Committee. The full text of the Charter of
the Audit Committee appears as Appendix 1 to this Proxy Statement.

    The primary duties of the Audit Committee are:

  To assist the Board in its oversight of (i) the integrity of the Company's
  financial statements, (ii) the Company's compliance with legal and regulatory
  requirements, (iii) the qualifications and independence of the Company's
  independent auditor; and (iv) the performance of the Company's internal audit
  function and independent auditor; and

  To prepare the report of the Committee that the rules of the Securities and
  Exchange Commission require be included in the Company's annual Proxy
  Statement.

    In addition to its regularly scheduled meetings, the Audit Committee is
available either as a group or individually to discuss any matters that might
affect the financial statements, internal controls or other financial aspects of
the operations of Minerals Technologies.

                                       5


DIRECTOR COMPENSATION

Fees

    Each of the directors, other than directors who are officers or employees of
Minerals Technologies, receives an annual retainer fee of $10,000 for serving as
a director, $1,000 for serving as a member of a committee of the Board, and an
additional $1,000 if serving as a committee chair. Non-employee directors also
receive a fee of $2,000 for each meeting of the Board they attend and $500 for
each committee meeting they attend. Directors also receive compensation under
the plans described below.

Nonfunded Deferred Compensation and Unit Award Plan for Non-Employee Directors

    Under the Nonfunded Deferred Compensation and Unit Award Plan for
Non-Employee Directors, directors who are not employees of Minerals Technologies
have the right to defer their fees. At each director's election, his or her
deferred fees will be credited to his or her account either as dollars or as
units which have the economic value of one share of Minerals Technologies stock.
Dollar balances in a director's account bear interest at a rate of return equal
to the rate of return for the Fixed Income Fund in the Minerals Technologies
Inc. Savings and Investment Plan. If a director elects to have his or her
deferred fees credited to his or her account as units, the number of units
credited is calculated by dividing the amount of the deferred fees by the
closing price of our common stock as of the last business day prior to the date
on which the fees would otherwise be paid.

    Each non-employee director is credited with 500 units upon first joining the
Board and with an additional 500 units each year as of the date of the Annual
Meeting of Stockholders, plus 65 units each year for serving as a member of a
committee of the Board and an additional 15 units for serving as chair of a
committee. In addition, each member receives 15 units for attending any
committee meeting and an additional 10 units for serving as chair of a committee
meeting.

    The units in a director's account are increased by the value of any
dividends on our common stock. In the case of cash dividends, the units are
increased by a number calculated by multiplying the cash dividend per share
times the number of units in the director's account on the related dividend
record date and dividing the result by the closing market price of the common
stock on the day prior to the dividend payment date. In the case of stock
dividends, the units would be increased by a number calculated by multiplying
the stock dividend per share times the number of units in the director's account
on the related dividend record date.

    At the time of the director's termination of service on the Board, the
amount held in his or her account is payable in cash only. Based on the
director's prior choice to accumulate dollars or units as described above, the
director receives either (i) the amount of his or her deferred fees plus accrued
interest, or (ii) an amount determined by multiplying the number of units in his
or her account by the closing market price of the common stock on the last
business day prior to the date of payment. Payments are made in a lump sum or in
installments, at the election of the director.

Stock Award and Incentive Plan

    Directors are eligible under the Minerals Technologies Stock Award and
Incentive Plan to receive options to purchase common stock, at the same time and
on the same basis as across-the-board options are granted to Minerals
Technologies' U.S.-based employees.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

    Mr. Steere, who is a director of Minerals Technologies, is a director and
former Chairman and Chief Executive Officer of Pfizer Inc. Dr. Valles, who is a
director and former Chairman and Chief Executive Officer of Minerals
Technologies, is a member of the Board of Directors of Pfizer Inc. During 2002,
Pfizer Inc. made a series of purchases of precipitated calcium carbonate from
Minerals Technologies totaling approximately $1.7 million. These transactions
were entered into by Minerals Technologies pursuant to arm's-length negotiations
in the ordinary course of business and on terms that we believe to be fair.

    Mr. Golub, a director of Minerals Technologies, is Managing Director of
Lazard Freres & Co. LLC. Minerals Technologies has engaged Lazard Freres to
provide investment banking services from time to time with respect to a variety
of financial matters. In addition, Lazard Freres acts as our broker in
connection with our ongoing program of repurchases of a portion of our
outstanding common stock. To obtain this business, Lazard Freres, in an
arm's-length transaction, agreed to meet a competitive bid structured as a fixed
commission on each share repurchased.

OPTION GRANTS IN LAST FISCAL YEAR

    This table provides information on options granted to the named executive
officers on January 24, 2002. The last two columns of the table show the
potential realizable value of the options in each of two hypothetical cases. The
first case assumes that the price of the stock increases at a rate of five per
cent per year over the term of the options, which would result in a price of
approximately $75.95 per share in 2012 and an increase in aggregate shareholder
value of approximately $592 million. The second case assumes that the price of
the stock increases at a rate of ten per cent per year over the term of the
options, which would result in a price of approximately $120.93 per share in
2012 and an increase in aggregate shareholder value of approximately $1,500
million. The actual market value of the stock at any future date may or may not
correspond to any of these hypothetical cases.

LONG-TERM INCENTIVE PLAN AWARDS IN LAST FISCAL YEAR

    The following table gives information concerning the participation of the
named executive officers in a long-term compensation plan adopted by the Company
in 2002. Under this plan, the named executive officers and certain other
executives were awarded the right to earn units which are equal in value to the
price of our common stock, except that the value of a unit may not be greater
than 125%, and may not be less than 75%, of the price of our common stock at the
beginning of the performance measurement period. Actual payouts of these units,
if any, will be in cash, and will be determined by a non-discretionary formula
which measures our performance over a three-year period using performance goals
that were determined by the Compensation and Nominating Committee and approved
by the Board. The formula is based on two performance criteria: a target return
on equity percentage over the three-year period, and total shareholder return
(including reinvestment of dividends) over the period relative to the S&P Midcap
400 Materials Index. If our performance in both measures is below the threshold
level set forth in the plan, then no units will be earned. To the extent the
Company's performance on either or both measures exceeds the threshold
performance level, a varying amount of units up to the maximum will be earned.
The plan is also discussed in the Report of the Compensation and Nominating
Committee below.



                                                                                 ESTIMATED FUTURE PAYOUTS UNDER

(1) The actual number of units that will be paid out at the end of the
    performance period, if any, cannot be determined because the units earned by
    the named executive officers will be based partly upon the Company's future
    return on equity and partly upon its future performance compared to the
    future performance of the S&P Midcap 400 Materials Index.

(2) If the Company's performance in both measures is below the established
    threshold performance levels, then no units will be earned. To the extent
    the Company's performance on either or both measures exceeds the threshold
    performance level, a varying amount of units up to the maximum will be
    earned.

             REPORT OF THE COMPENSATION AND NOMINATING COMMITTEE ON
                             EXECUTIVE COMPENSATION

    The following report of the Compensation and Nominating Committee of the
Board sets forth the Committee's policies applicable to the executive officers
of Minerals Technologies.

        This report is provided by the Compensation and Nominating Committee
    of the Board of Directors. The members of the Compensation and
    Nominating Committee, whose names follow this report, are independent
    outside directors who are not employees of Minerals Technologies, and
    none serves as a member of the compensation committee of any company
    that has an executive officer who also serves as a director of Minerals
    Technologies.

        In 2002, the Compensation and Nominating Committee adhered to its
    policy that compensation programs should reward the achievement of the
    short-term and long-term goals and objectives of Minerals Technologies,
    and that compensation should be related to the value created for its
    stockholders. The Committee sets high performance targets and rewards
    their achievement with total cash compensation that is above the average
    and heavily weighted towards short term incentives based on Company
    performance, but within the range of compensation of similarly placed
    executives in manufacturing firms of comparable size. Consistent with
    this policy, each elected corporate officer's annual compensation is
    determined by reviewing the previous year's compensation and, if
    appropriate, applying a market and performance driven adjustment, and an
    incentive payment opportunity, determined as stated below in this
    report.

                                    BASE PAY

        Each employee of Minerals Technologies receives an annual
    performance rating. The performance rating of the Chairman, President
    and Chief Executive Officer is assigned by the Compensation and
    Nominating Committee and approved by the Board. The performance ratings
    of the other elected corporate officers, including those named in the
    Summary Compensation Table appearing in this proxy statement (the
    'principal executives'), are assigned by the Chairman, President and
    Chief Executive Officer and reviewed by the Compensation and Nominating
    Committee.

        Based on Minerals Technologies' performance, general business
    outlook and industry compensation trends, management each year sets a
    guideline corporate-wide average percentage compensation adjustment for
    all employees for the coming year. The percentage increase received by a
    particular employee is determined on the basis of the employee's
    performance rating and current compensation level within the range
    established for the employee's position. The adjustment may range from
    no increase to up to twice the corporate-wide average adjustment
    referred to above, depending upon individual performance.

                          SHORT-TERM INCENTIVE PAYMENT

        The Committee has continued the format of the executive compensation
    program for 2002 under which a large portion of an executive's total
    compensation is placed at risk dependent on the annual performance of
    the Company, and a lesser portion of compensation is dependent on the
    achievement of longer-term goals. Short-term incentive payments are
    expressed as a percentage of base compensation. Depending upon the
    extent to which the company's performance during the year meets targets
    established by the Board early in the year, a bonus payment ranging from
    0% (for performance of less than 85% of targets) up to 150% of base
    compensation (for performance greater than 120%) is available to the
    Chief Executive Officer. The bonus payments can range from 0% up to 120%
    of base compensation for other principal executives. These payments,
    which are made in the following year, are shown as the Bonus for each
    principal executive in the year to which they are attributable in the
    Summary Compensation Table included in this proxy statement. This
    incentive program is intended to more closely link the principal
    executives' pay to the growth of the company and the value created for
    stockholders in the preceding year. For 2002, this was measured by net
    income

                                       13


    growth as compared to target, on a corporate and divisional basis. At
    the beginning of each year, the Board establishes a target for these
    factors and sets up a scoring system to measure at year-end the extent
    to which the targets are met. At year-end, a formula is applied to the
    scores to determine the level of the incentive payment to be received by
    the principal executive. The Compensation and Nominating Committee then
    considers whether there are other factors that should also be taken into
    consideration in establishing the overall level of compensation of each
    principal executive. It will, for example, take into consideration
    actions that have been taken by management to benefit shareholders in
    the longer term that may have a negative impact on the factors and
    annual targets established. During 2002, Minerals Technologies did not
    fully achieve its targets on a corporate basis, but did exceed target in
    certain divisions. This resulted in incentive payments that were below
    established targets. The formula produced a payment of $200,063 for Mr.
    Saueracker, and the Compensation and Nominating Committee agreed that he
    should receive that amount as his 2002 incentive payment, to be paid in
    2003.

                              LONG-TERM INCENTIVE

        The long-term incentive plan, first introduced in 2001, allows for
    the grant of performance units vesting at the end of three years
    according to the achievement of pre-established goals. For the first
    three-year period (2001 through 2003) the goals are based 70% on
    cumulative earnings per share targets and 30% on the total shareholder
    return compared to the S&P Midcap 400 Materials Index at the end of the
    period. For the second three-year period (2002 through 2004) the goals
    are based 70% on return on equity targets and 30% on total shareholder
    return compared to the S&P Midcap 400 Materials Index at the end of the
    period. No performance units vest if the achievement against both goals
    is less than 80%. Between 80-120% performance on either goal, units vest
    ratably between 50-150% of the target number. Performance units are
    equal to the price of MTI stock except that they cannot exceed 125% of
    the price at the beginning of the period and they cannot be less than
    75% of that price. For the first three-year plan, the Board approved
    5,000 target performance units for Mr. Saueracker, for which he will be
    eligible at the end of 2003. Mr. Saueracker's target range of units is
    from 2,500 to 7,500 depending upon the company's performance against the
    pre-established goals. For the second three-year plan, the Board has
    again approved 5,000 target performance units for which he will be
    eligible at the end of 2004. The target range of units is from 2,500 to
    7,500 depending upon the company's performance against the
    pre-established goals.

                                  STOCK AWARDS

        The Compensation and Nominating Committee grants options to purchase
    Minerals Technologies common stock to the principal executives on a
    regular basis. In addition, special grants may be made to reflect
    extraordinary achievements or in connection with important promotions.
    In addition to making grants to key executives, Minerals Technologies
    believes that, where practical and economical, all employees should have
    the opportunity to participate in the future growth of the firm through
    equity participation.

        In 2003 the Committee approved a deferred, restricted stock award to
    Mr. Massimine in the amount of 255 shares. The shares vest three years
    from the date of award.

                    DISCRETIONARY AUTHORITY OF THE COMMITTEE

        The Compensation and Nominating Committee believes that the
    application of the procedures described above will generally result in
    fair and adequate compensation to each principal executive. However, the
    Compensation and Nominating Committee also believes that no arbitrary
    formula is an adequate substitute for individual judgments in all cases,
    particularly in determining the value of a principal executive's
    contribution to the success of the company. Therefore, the Compensation
    and Nominating Committee may from time to time use its discretion in
    deviating from the above procedures (including, possibly, modifying the
    factors

                                       14


    discussed above or varying their weighting) to set compensation levels
    for the principal executives and others that best serve the interests of
    the company and its stockholders.

                      INTERNAL REVENUE CODE SECTION 162(M)

        Internal Revenue Code Section 162(m) and regulations thereunder,
    which limit the deductibility of certain executive compensation in
    excess of $1,000,000, did not result in any disallowance of a deduction
    for compensation payments made by Minerals Technologies for the 2002
    fiscal year. However, the Compensation and Nominating Committee has
    determined that, in order to retain the discretion referred to in the
    previous paragraph, it reserves the right to make compensation payments
    that in part may not qualify for a tax deduction because of the
    limitations of Internal Revenue Code Section 162(m).

COMPENSATION AND NOMINATING COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    The Compensation and Nominating Committee is composed of Mr. Curcio (Chair),
Mr. Meister and Mr. Steere. None of the members of the Committee is or has ever
been an officer or employee of Minerals Technologies or any of its subsidiaries.
During 2002 no executive officer of Minerals Technologies served as a director
or a member of the compensation committee of another entity, any of whose
executive officers served as a member of the Compensation and Nominating
Committee. In addition, no executive officer of Minerals Technologies served as
a member of the compensation committee of another entity, any of whose executive
officers served as a director of Minerals Technologies.

           EMPLOYMENT, TERMINATION AND CHANGE-IN-CONTROL ARRANGEMENTS

EMPLOYMENT AGREEMENTS

    In March 2001, Minerals Technologies entered into employment agreements with
the following individuals for the indicated terms and for not less than the
annual base salaries indicated: Mr. Saueracker, 24 months, $500,000; Mr. Sorel,
18 months, $235,000; Mr. Crabtree, 18 months, $250,000; Mr. Gray, 18 months,
$250,000; Mr. Massimine, 18 months, $200,000; Mr. Bardach, 18 months, $275,000;
and Mr. Dulski, 24 months, $385,000. The term of each of these agreements is
extended on the first day of each month for an additional month, unless either
the employee or the employer gives the other written notice that the agreement
should not be further extended. Each of the named executive officers may also
receive salary increases and annual bonuses in amounts to be determined by the
Board or the Compensation and Nominating Committee. The agreements also entitle
the named executive officers to participate in employee benefit plans and other
fringe benefits that are generally available to our executive employees.

    Under the agreements, each named executive officer has agreed to comply with
certain customary provisions, including covenants not to disclose our
confidential information at any time and not to compete with our business during
the term of the agreement and, subject to our continued payment of amounts under
the agreement, for two years thereafter. We may terminate the employment
agreements before the end of the specified term of employment for 'cause' as
defined in the agreements.

SEVERANCE AGREEMENTS

    Minerals Technologies has entered into severance agreements with certain of
its executive officers, including each of the named executive officers. The
agreements continue through December 31 of each year, and are automatically
extended in one-year increments unless we choose to terminate them. If a change
in control occurs, the severance agreements are effective for a period of four
years from the end of the then existing term. These agreements are intended to
provide for continuity of management in the event of a change in control of
Minerals Technologies.

    If, following a change in control, the executive is terminated by Minerals
Technologies for any reason, other than for disability, death, retirement or for
cause (as defined in the agreements), or if the executive terminates his or her
employment for good reason (as defined in the agreements), then the executive is
entitled to a severance payment of 2.99 times the executive's base amount (as
defined in the agreements). The severance payment generally will be made in a
lump sum. For a period of up to two years following a termination that entitles
an executive to severance payments, Minerals Technologies will provide life,
disability, accident and health insurance coverage substantially similar to the
benefits provided before termination, except to the extent such coverages would
result in an excise tax being imposed under Section 4999 of the Internal Revenue
Code.

    The agreements also provide that upon the occurrence of certain stated
events that constitute a 'potential change in control' of Minerals Technologies,
the executive agrees not to voluntarily terminate his employment with Minerals
Technologies for a six-month period.

    Under the severance agreements, a change in control includes any of the
following events unless approved by the Board: (i) we are required to report a
'change in control' in accordance with the Securities Exchange Act of 1934; (ii)
any person acquires 15% of our voting securities; (iii) a majority of our
directors are replaced during a two-year period; or (iv) our stockholders
approve a merger, liquidation or sale of assets.

STOCK OPTION PLAN

    The Stock Award and Incentive Plan provides that all non-vested stock
options granted under the plan may, at the discretion of the Compensation and
Nominating Committee, be made immediately exercisable upon the employee's
retirement or upon a change in control of Minerals Technologies (as defined in
the plan).

                                       17


RETIREMENT PLANS

    Each of the named executive officers is entitled to benefits under the
defined benefit pension plans which we maintain. The Retirement Plan is a tax
qualified pension plan which pays retirement benefits within the limits
prescribed by the Internal Revenue Code. The Nonfunded Supplemental Retirement
Plan is an unfunded, non-tax qualified pension plan which pays retirement
benefits in excess of such tax limits. Benefits under the Retirement Plan and
the Nonfunded Supplemental Retirement Plan are based upon an annuity equal to
the greater of (i) 1.4% of a participant's career earnings or (ii) 1.75% of a
participant's career earnings less 1.5% of primary Social Security benefits,
multiplied by years of service up to 35 years. For purposes of this formula, a
participant's 'career earnings' are based on the average earnings for the five
highest consecutive calendar years prior to January 1, 1998, and on actual
earnings for periods after December 31, 1997.

    Under the Retirement Plan and the Nonfunded Supplemental Retirement Plan,
each of the named executive officers would be entitled to the following annual
benefits after retirement: Mr. Saueracker, $181,696; Mr. Sorel, $120,561;
Mr. Crabtree, $139,477; Mr. Gray, $95,386; Mr. Massimine, $78,756; Mr. Bardach,
$11,809; and Mr. Dulski, $118,968. This assumes that (i) payments will be made
in the form of a 50% joint and survivor annuity; (ii) employment will be
continued until normal retirement at age 65 (in the case of Mr. Bardach, until
September 30, 2003, and in the case of Mr. Dulski, until December 31, 2003); and
(iii) creditable compensation will continue at 2002 levels until retirement.

GRANTOR TRUST

    In order to secure the benefits accrued under the Nonfunded Supplemental
Retirement Plan and the Nonfunded Deferred Compensation and Supplemental Savings
Plan (an unfunded, non-tax qualified plan which pays amounts in excess of the
limits which the Internal Revenue Code imposes on benefits under our Savings and
Investment Plan), Minerals Technologies has entered into an agreement
establishing a grantor trust within the meaning of the Internal Revenue Code.
Under the Grantor Trust Agreement, we are required to make certain contributions
of cash or other property to the trust upon the retirement of individuals who
are beneficiaries of those plans; upon the occurrence of certain events defined
as constituting a 'Change of Control'; and in certain other circumstances.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Based solely on a review of our records and of copies furnished to us of
reports under Section 16(a) of the Securities Exchange Act of 1934, or written
representations that no such reports were required, we believe that all reports
required to be filed by our directors, officers and greater than 10%
shareholders were timely filed, except that following the elimination of a de
minimis exception to the rules under the Act, one report was filed late on
behalf of each of the directors.

                                       18


                         ITEM 2 -- APPROVAL OF AUDITORS

    The Audit Committee of the Board has appointed KPMG LLP to serve as our
independent auditors for the current fiscal year, subject to the approval of the
stockholders. KPMG LLP and its predecessors have audited the financial records
of the businesses that compose Minerals Technologies for many years. We consider
the firm well qualified.

    We expect that representatives of KPMG LLP will be present at the Annual
Meeting of Stockholders. These representatives will have the opportunity to make
a statement if they wish to do so, and will be available to respond to
appropriate questions.

    THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR RATIFICATION OF THE
APPOINTMENT OF KPMG LLP AS OUR INDEPENDENT AUDITORS FOR THE 2003 FISCAL YEAR.

                         REPORT OF THE AUDIT COMMITTEE

    The following report sets forth certain steps taken by the Audit Committee
in connection with the audited financial statements of Minerals Technologies
Inc. for the year 2002.

        This report is provided by the Audit Committee of the Board of
    Directors. The Committee is composed of Mr. Pasquale (chair), Mr. Dunham,
    Mr. Golub and Dr. Johnson. The Board of Directors has determined that each
    of the members of the Audit Committee is independent and financially
    literate in accordance with the rules of the New York Stock Exchange as well
    as being independent under the rules of the Securities and Exchange
    Commission. The Board has also determined that Mr. Pasquale, Chair of the
    Audit Committee, has 'financial expertise' for purposes of the rules of the
    New York Stock Exchange.

        KPMG LLP audited the annual financial statements of Minerals
    Technologies Inc. for the years 2002 and 2001, and also reviewed the
    financial statements included in the quarterly reports on Form 10-Q filed
    during 2002 and 2001. The aggregate fees billed by KPMG LLP for professional
    services rendered in performing this work, and for all other services
    rendered by KPMG LLP during 2002 and 2001, are shown in the following table.



                                                2002        2001
                                                ----        ----
                                                    
     Audit Fees............................  $1,138,000   $906,000
     Audit Related Fees....................      71,000     38,000
     Tax Fees..............................     148,000     50,000
     All Other Fees........................       3,000      4,000
                                             ----------   --------
     Total Fees............................  $1,360,000   $998,000
                                             ----------   --------
                                             ----------   --------


        The Committee considers the provision of the services included in 'All
    Other Fees' to be compatible with maintaining the independence of KPMG LLP
    as independent auditors of Minerals Technologies Inc.

        The Committee has reviewed and discussed with the management of Minerals
    Technologies Inc. its December 31, 2002, audited financial statements; has
    discussed with KPMG LLP, the independent auditors of those financial
    statements, the matters required to be discussed by Statement on Auditing
    Standards No. 61 (Codification of Statements on Auditing Standards),
    AU 'SS'380; has received from the auditors the written disclosures and the
    letter required by Independence Standards Board Standard No. 1,
    'Independence Discussions with Audit Committees'; and has discussed with the
    auditors the matter of their independence.

                                       19


        Based on the review and discussions referred to in the previous
    paragraph, the Committee recommended to the Board of Directors that the
    audited financial statements be included in Minerals Technologies Inc.'s
    Annual Report on Form 10-K for filing with the Securities and Exchange
    Commission.

                                          Michael F. Pasquale, Chair
                                          Duane R. Dunham
                                          Steven J. Golub
                                          Kristina M. Johnson

The Audit Committee's policies and procedures for engaging the independent
accountant to perform services other than audit, review and attestation services
call for any such services to be pre-approved by the Committee as a whole or by
a designated member of the Committee.

                               PROCEDURAL MATTERS

CASTING AND COUNTING OF VOTES

    Votes cast at the Annual Meeting (whether by proxy or in person) will be
counted by an independent inspector of election appointed by Minerals
Technologies. If a proxy form is returned properly signed but not marked, it
will be voted according to management's recommendations on all proposals.

    The Board knows of no other business that will be presented at the Annual
Meeting. The proxy confers discretionary authority with respect to any other
matters which come before the Annual Meeting, and the individuals named in the
proxy will vote in accordance with their judgment on such matters if they arise.

QUORUM

    The by-laws of Minerals Technologies state that a quorum for all meetings of
stockholders consists of the holders of a majority of the shares of common stock
issued and outstanding and entitled to vote, present in person or by proxy. The
inspector of election will treat shares of common stock represented by a
properly signed and returned proxy as present at the Annual Meeting for purposes
of determining a quorum, whether the proxy is marked as casting a vote or
abstaining. On the Record Date there were 20,085,424 shares of common stock
issued and outstanding.

    The inspector of election will also treat shares represented by 'broker
non-votes' as present for purposes of determining a quorum. Broker non-votes are
shares held in record name by brokers or nominees, as to which the broker or
nominee (i) has not received instructions from the beneficial owner or person
entitled to vote, (ii) does not have discretionary voting power under applicable
New York Stock Exchange rules or the document under which it serves as broker or
nominee, and (iii) has indicated on the proxy card, or otherwise notified us,
that it does not have authority to vote the shares on the matter.

VOTE REQUIRED FOR APPROVAL: ELECTION OF DIRECTORS

    The by-laws state that directors are to be elected by a plurality vote of
the shares of stock present and entitled to vote, in person or by proxy, at the
Annual Meeting. Abstentions and broker non-votes as to the election of directors
will not affect the outcome of the election of directors.

VOTE REQUIRED FOR APPROVAL: OTHER QUESTIONS

    The by-laws state that except as otherwise provided by law or in the
Certificate of Incorporation or the by-laws, all questions other than the
election of directors are determined by a majority of the votes cast on the
question. All votes cast in favor of a given proposal, and all votes cast
against it, are added together for a total sum of votes on that proposal.
Abstentions and broker non-votes as to the proposal will not affect the outcome,
as they will not be included in calculating the number of votes necessary for
approval and will not count as votes cast for or against the question.

COST OF SOLICITING PROXIES

    The cost of this solicitation is being borne by Minerals Technologies. In
addition to soliciting proxies through the mail using this Proxy Statement, we
may solicit proxies by telephone, facsimile, electronic mail and personal
contact. These solicitations will be made by our regular employees without
additional compensation. We have also engaged Morrow & Co., Inc. to assist in
this solicitation of proxies, and we have agreed to pay that firm $4,000 for its
assistance, plus expenses.

STOCKHOLDER PROPOSALS

    The Compensation and Nominating Committee will consider nominations of
candidates for director, and the Board of Directors will consider other items of
business, which are proposed by stockholders. The by-laws describe the
procedures which a stockholder must follow to nominate persons for election as
directors or to introduce an item of business at a meeting of stockholders.
These procedures provide that nominations for director and items of business to
be introduced at an annual

                                       21


meeting of stockholders must be submitted in writing to the Secretary of
Minerals Technologies at The Chrysler Building, 405 Lexington Avenue, New York,
NY 10174-1901. If intended to be considered at an annual meeting, the nomination
or proposed item of business must be received not less than 70 days nor more
than 90 days in advance of the first anniversary of the previous year's annual
meeting. Therefore, for purposes of the 2004 annual meeting, any nomination or
proposal must have been received between February 22 and March 13, 2004. With
respect to any other meeting of stockholders, the nomination or item of business
must be received not later than the close of business on the tenth day following
the date of our public announcement of the date of the meeting.

            CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
                         OF MINERALS TECHNOLOGIES INC.

I. PURPOSE

    The primary purposes of the Audit Committee (the 'Committee') are to:

    1.  Assist the Board of Directors (the 'Board') in its oversight of (i) the
        integrity of the Company's financial statements, (ii) the Company's
        compliance with legal and regulatory requirements, (iii) the
        qualifications and independence of the Company's independent auditor;
        and (iv) the performance of the Company's internal audit function and
        independent auditor; and

    2.  Prepare the report of the Committee that the rules of the Securities and
        Exchange Commission (the 'Commission') require be included in the
        Company's annual proxy statement.

To fulfill these duties, the Audit Committee shall have the powers and
responsiblities enumerated in Sections IV and V, below.

II. MEMBERSHIP

    The Committee shall be composed of three or more directors as determined by
the Board, each of whom shall be independent and free from any relationship
that, in the opinion of the Board, would interfere with the exercise of his or
her independent judgment as a member of the Committee. For purposes of
determining whether or not a director is independent, the Board shall, at a
minimum, apply the standards set forth in Section 303A of the Listed Company
Manual of the New York Stock Exchange (the 'NYSE Manual'), including the
proposed requirement that no Committee member may receive fees from the Company
other than director's fees, and Section 301 of the Sarbanes-Oxley Act of 2002
(the 'Act'). All members of the Committee shall have a working familiarity with
basic finance and accounting practices and must be financially literate, as such
qualification is interpreted by the Board, and at least one member of the
Committee shall be an 'audit committee financial expert' as defined by the
Commission. Committee members may enhance their familiarity with finance and
accounting by participating in educational programs.

    The members of the Committee shall be elected by the Board at the annual
organizational meeting of the Board or until their successors shall be duly
elected and qualified. Unless a Chair is elected by the full Board, the members
of the Committee may designate a Chair by majority vote of the full Committee
membership.

III. MEETINGS

    The Committee shall meet at least four times annually, or more frequently as
circumstances dictate. As part of its job to foster open communications, the
Committee should meet at least annually with management, the director of the
internal auditing department, and the independent auditor in separate executive
sessions to discuss any matters that the Committee or any of these groups
believe should be discussed privately. In addition, the Committee, or at least
the Chair, should meet with the independent auditor and management quarterly to
review the Company's Form 10-Q, and the matters required to be discussed by
Statement of Auditing Standards ('SAS') No. 61, prior to their filing or prior
to the release of earnings reports.

IV. GENERAL POWERS

    The general powers of the Audit Committee shall be to:

     1.  Oversee management's maintenance of the reliability and integrity of
         the accounting policies and financial reporting and disclosure
         practices of the Company;

                                      A1-1


     2.  Oversee management's establishment and maintenance of processes to
         assure that an adequate system of internal control is functioning
         within the Company; and

     3.  Oversee management's establishment and maintenance of processes to
         assure compliance by the Company with all applicable laws, regulations,
         and Company policies.

V. SPECIFIC POWERS

    The specific powers of the Audit Committee shall be to:

     1.  Hold such regular meetings as may be necessary and such special
         meetings as may be called by its Chair or at the request of the public
         accounting firm serving as the Company's independent auditors or of the
         Company's Controller;

         Company, consistent with the provisions of the Act and the NYSE Manual;
         discuss with the independent auditors any such disclosed relationships
         and their impact on the independent auditor's independence; take
         appropriate action in response to the auditor's report to satisfy
         itself of the independent auditor's independence; and terminate the

         the Committee may deem desirable;

     6.  Review with management, the independent auditor, and the internal

         to one or more Committee members, who shall report any pre-approved
         decision to the full Committee at its next regularly scheduled meeting;

     8.  Report the pre-approval of any permitted non-audit services to
         management for disclosure in the Company's periodic reports;

     9.  Make itself available during the course of the audit or at other times,

                                      A1-2
