GENERAL INFORMATION

        The enclosed proxy is being solicited by the Board of Directors of IKONICS Corporation, a Minnesota corporation ("IKONICS" or the "Company"), for use in connection with the Annual Meeting of Shareholders to be held on April 27, 2017 at The Kitchi Gammi Club, 831 E. Superior Street, Duluth, Minnesota, at 1:00 p.m., Central Time, and at any adjournments thereof. Only shareholders of record at the close of business on March 6, 2017 will be entitled to vote at such meeting or adjournment. Proxies in the accompanying form which are properly signed, duly returned to the Company and not revoked will be voted in the manner specified. A shareholder executing a proxy retains the right to revoke it at any time before it is exercised by providing notice in writing to the Secretary of the Company of termination of the proxy's authority or a properly signed and duly returned proxy bearing a later date.

        The address of the principal executive office of the Company is 4832 Grand Avenue, Duluth, Minnesota 55807 and the telephone number is (218) 628-2217. The mailing of this Proxy Statement and the Board of Directors' form of proxy to shareholders will commence on or about March 24, 2017. This Proxy Statement is available from the Investor Relations page of our website at www.ikonics.com/investor-relations.php.

        The Company will pay the cost of soliciting proxies in the accompanying form. In addition to solicitation by mail, certain directors, officers and employees of the Company may solicit proxies by telephone, regular or electronic mail, or personal contact, and have requested brokerage firms and custodians, nominees and other record holders to forward soliciting materials to the beneficial owners of stock of the Company and will reimburse them for their reasonable out-of-pocket expenses in so forwarding such materials.

        The Common Stock of the Company, par value $.10 per share, is the only authorized and issued voting security of the Company. At the close of business on March 6, 2017, there were 2,018,753 shares of Common Stock issued and outstanding, each of which is entitled to one vote. Holders of Common Stock are not entitled to cumulate their votes for the election of directors.

        A plurality of the votes cast is required for election of the director nominees listed under "Election of Directors" in this Proxy Statement. The affirmative vote of the holders of a majority of the outstanding shares of Common Stock present in person or represented by proxy at the meeting and entitled to vote is required to ratify the selection of the Company's independent registered public accounting firm. If the advisory vote on the compensation of the named executive officers included in this Proxy Statement receives more votes "for" than "against," then it will be deemed to be approved.

        A shareholder voting through a proxy who abstains with respect to any matter is considered to be present and entitled to vote on such matter at the meeting and is in effect a negative vote with respect to the proposal relating to ratification of the Company's independent registered public accounting firm. Abstentions will have no effect on the advisory vote to approve the compensation of the named executive officers as disclosed in this Proxy Statement. A shareholder (including a broker) who does not have or does not give authority to vote, or withholds authority to vote, on any proposal shall not be considered present and entitled to vote on such proposal.

Committees of the Board of Directors and Meeting Attendance

        The Board of Directors met five times during fiscal 2016—four were regular meetings and one was an additional meeting. All incumbent directors attended at least 75% of the meetings of the Board and of the committees on which they served held during the periods for which they served as a director except for Dr. Carlson. The Company currently has an Audit Committee, a Compensation Committee and a Nominating Committee.

        The following is a description of the functions performed by each of the Committees:

Audit Committee

        The Company's Audit Committee presently consists of Messrs. Lee (Chairman), Carlson, Engbrecht, Harper, Harris and Simonson and Ms. Bohren. All of the members of the Audit Committee are "independent" as that term is defined in the applicable listing standards of The NASDAQ Stock Market and Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). In addition, the Board of Directors has determined that Messrs. Lee and Simonson each is an "audit committee financial expert" as defined by applicable regulations of the Securities and Exchange Commission. The Audit Committee provides assistance to the Board of Directors in fulfilling the Board's duties relating to corporate accounting, reporting practices of the Company and the quality and integrity of the Company's financial reports. Among other things, the Audit Committee selects and appoints the Company's independent registered public accounting firm, meets with the independent registered public accounting firm and financial management to review the scope of the audit and the audit procedures, reviews annually the responsibilities of the Audit Committee and recommends to the Board of Directors any changes to these responsibilities. The responsibilities of the Audit Committee are set forth in the Audit Committee Charter, adopted by the Company's Board of Directors on February 23, 2004. A copy of the Audit Committee Charter is included as Exhibit A to the Company's

Proxy Statement for its 2016 Annual Meeting of Shareholders. The Audit Committee met four times during fiscal 2016, once each quarter.

Compensation Committee

        The Company's Compensation Committee presently consists of Messrs. Harper (Chairman), Carlson, Engbrecht, Harris, Lee, Simonson and Ms. Bohren. All of the members of the Compensation Committee are "independent" as that term is defined in the applicable listing standards of The NASDAQ Stock Market. The Compensation Committee periodically reviews and acts upon a compensation package for the Chief Executive Officer and the Company's other executive officers, and sets compensation policy for the other employees of the Company. In addition, the Compensation Committee acts upon management recommendations concerning employee stock options, bonuses and other compensation and benefit plans. The Compensation Committee also administers the IKONICS Corporation 1995 Stock Incentive Plan. The responsibilities of the Compensation Committee are set forth in the Compensation Committee Charter, adopted by the Company's Board of Directors on February 28, 2013. Pursuant to the Compensation Committee Charter, the Committee has authority to delegate any of its responsibilities to subcommittees as the Committee may deem appropriate, provided that the subcommittees are composed entirely of independent directors. A copy of the Compensation Committee Charter is included as Exhibit B to the Company's Proxy Statement for its 2016 Annual Meeting of Shareholders. The Compensation Committee did not meet during fiscal 2016.

Nominating Committee

        The Company's Nominating Committee presently consists of Ms. Bohren (Chairman) and Messrs. Carlson, Engbrecht, Harper, Harris, Lee and Simonson. All of the members of the Nominating Committee are "independent" as that term is defined in the applicable listing standards of The NASDAQ Stock Market. The purposes of the Nominating Committee are to identify individuals qualified to become Board members and to approve director-nominees to be considered for election by shareholders and for election by the Board to fill any vacancy or newly created directorship. The responsibilities of the Nominating Committee are set forth in the Nominating Committee Charter, which was included as Exhibit A to this Proxy Statement. The Nominating Committee met once during fiscal 2016.

        The Nominating Committee has established a policy with regard to the consideration of any director candidates recommended by the Company's shareholders. The Nominating Committee will consider director candidates recommended by a Company shareholder provided that the shareholder sends the Company a written notice received by the Secretary of the Company that (i) states the name and address of the shareholder identifying the candidate as that information appears on the Company's books and records and the number of shares of the Company owned by the recommending shareholder and (ii) provides the following information about the candidate:

1.

name, age and business and residential addresses;



2.

principal occupation or employment;



3.

number of shares of the Company beneficially owned;



4.

statement of the person's citizenship; and



5.

any other information that must be disclosed about nominees in proxy solicitations pursuant to Regulation 14A under the Exchange Act (including the candidate's written consent to be named as a nominee and to serve as a director if elected).

        The Company may require any proposed candidate to furnish such other information as may reasonably be required by the Nominating Committee to determine the eligibility of the proposed

6

---

nominee to serve as a director. Provided a shareholder satisfies the requirements described above, the Nominating Committee will consider director candidates recommended by shareholders in the same manner that it considers all other director candidates. All director candidates must meet certain minimum qualifications established by the Nominating Committee from time to time, and the Nominating Committee will assess the experience, integrity, competence, diversity, skills and dedication to the Company of all director candidates. The Nominating Committee does not have an independent policy with regard to considering the diversity of the Company's directors. The Nominating Committee will consider a number of features when evaluating diversity, including age, gender, ethnicity and professional experiences. As indicated above, diversity is one factor in the total mix of information the Board of Directors considers when evaluating director candidates. Shareholders who wish to suggest qualified candidates should write to the Office of the Corporate Secretary of IKONICS Corporation, at 4832 Grand Avenue, Duluth, Minnesota 55807, stating the information described above and any other relevant details concerning the candidate's qualifications for consideration by the Nominating Committee.

Board Leadership Structure and Role in Risk Oversight

        Mr. Ulland has served in the combined roles of Chairman and Chief Executive Officer since 2000. Mr. Ulland's combined service as Chairman and Chief Executive Officer creates unified leadership for the Company. This leadership structure demonstrates to customers and shareholders that the Company is under strong leadership and minimizes the potential duplication of efforts among management and the directors. The Board of Directors does not have a lead independent director and does not believe that one is necessary in light of the Company's size and the lengthy experience the majority of the directors have working with Mr. Ulland. The Board of Directors believes its leadership structure allows the Company to operate most efficiently and is in the best interests of the Company and its shareholders.

        The Company's management is responsible for day-to-day risk management of the Company. Management reports to the Board of Directors on the material risks the Company faces when management determines that the Company's risk profile materially changes. The Board of Directors uses management's reports to evaluate the Company's exposure to risks in light of the Company's business plan and growth strategies. The Board of Directors primarily focuses on risks in the areas of operations, liquidity and regulatory changes and compliance, which the Board of Directors believes are the areas most likely to potentially impact the Company in a material way.

Director Compensation

        Each non-employee director of the Company receives a quarterly retainer of $2,000, plus meeting fees of $2,000 for each regular meeting of the Board of Directors, which totaled four in 2016. Fees are not paid for committee meetings. From time to time, the Company's non-employee directors have been awarded options to purchase the Company's Common Stock under the 1995 Stock Incentive Plan and Mr. Ulland has been awarded stock options under such plan in connection with his position as Chairman, President and Chief Executive Officer. No such grants of stock options have been made since 2003. The following table sets forth the total compensation paid to each director for fiscal 2016. Mr. Ulland did not receive separate compensation for his service as a director during fiscal 2016.

DIRECTOR COMPENSATION

Shareholder Communication with the Board of Directors and Director Attendance at Annual Meetings

        The Board provides a process for shareholders to send communications to the Board or any of the directors. Shareholders may send written communications to the Board of Directors or specified individual directors by addressing their communication to Chief Financial Officer, IKONICS Corporation, 4832 Grand Avenue, Duluth, Minnesota 55807, by U.S. mail. The communications will be collected by the Chief Financial Officer and delivered, in the form received, to the Board or, if so addressed, to a specified director.

        The Company does not have a formal policy regarding attendance by members of the Board of Directors at the Company's Annual Meetings of Shareholders. The Company has always encouraged its directors to attend its annual meeting of shareholders and expects to continue this informal policy. In 2016, all Company directors, other than Dr. Carlson and Mr. Harris, attended the Company's Annual Meeting of Shareholders.

REPORT OF THE AUDIT COMMITTEE

        The role of the Company's Audit Committee, which is currently composed of seven independent non-employee directors, is one of oversight of the Company's management and the Company's independent registered public accounting firm in regard to the Company's financial reporting and the Company's controls with respect to accounting and financial reporting. In performing its oversight function, the Audit Committee relied upon advice and information received in its discussions with the Company's management and independent registered public accounting firm.

        The Audit Committee has (i) reviewed and discussed the Company's audited financial statements for the fiscal year ended December 31, 2016 with the Company's management; (ii) discussed with the Company's independent registered public accounting firm the matters required to be discussed by the applicable Public Company Accounting Oversight Board standard regarding communication with audit committees; (iii) received the written disclosures and the letter from the Company's independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence; and (iv) discussed with the independent registered public accounting firm the independent registered public accounting firm's independence.

        Based on the review and discussions with management and the Company's independent registered public accounting firm referred to above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on

Form 10-K for the fiscal year ended December 31, 2016 for filing with the Securities and Exchange Commission.

Principal Accounting Firm Fees

        During the period covering the fiscal years ended December 31, 2016 and 2015, RSM US LLP (formerly McGladrey LLP through October 25, 2015) performed the following professional services:

        The Audit Committee's current practice on pre-approval of services performed by the independent registered public accounting firm is to approve annually all audit services and, on a case-by-case basis, all permitted non-audit services to be provided by the independent registered public accounting firm during the fiscal year. The Audit Committee reviews each non-audit service to be provided and assesses the impact of the service on the auditor's independence. In addition, the Audit Committee may pre-approve other non-audit services during the year on a case-by-case basis.

EXECUTIVE COMPENSATION

SUMMARY COMPENSATION TABLE

        The following table sets forth certain information regarding compensation for the fiscal years ended December 31, 2016 and December 31, 2015, provided to the Chief Executive Officer and the two other most highly compensated executive officers who received remuneration exceeding $100,000 during fiscal 2016 and 2015 (the "Named Executive Officers").

        The Company has not entered into employment agreements with any of the Named Executive Officers. The amounts portrayed in the table above under "All Other Compensation" represent the Company's contribution to its salary deferral plan adopted under Section 401(k) of the Internal Revenue Code. The Company's executive officers are eligible to participate in a 401(k) defined contribution plan. In any plan year, the Company will contribute to each participant up to 5% of the participant's compensation into the 401(k) plan. Each of the Named Executive Officers participated in the 401(k) plan during fiscal 2016 and 2015 and received contributions.

        The Company maintains an annual bonus program pursuant to which executive officers are eligible to receive cash bonuses equal to a percentage of the year's bonus pool. Amounts shown in the "Non-Equity Incentive Plan Compensation" column represent payments pursuant to the Company's

10

---

bonus program for the applicable fiscal year. The fiscal 2016 and fiscal 2015 bonus pools were set at 10% of the amount by which net income before income taxes (as adjusted for unusual items of income or expense) ("EBT") for the applicable fiscal year exceeded the EBT target for that fiscal year. For fiscal year 2016 and 2015, losses in the amount of approximately $937,000 and $857,000, respectively, incurred by the Company's Advance Material Solutions Division were excluded from the bonus pool, as the Compensation/Succession Committee determined that this is a newer business in which the Company is still investing substantially. For fiscal 2016 and fiscal 2015, Mr. Ulland was eligible to receive a bonus equal to 28% of the pool. For fiscal 2016 and fiscal 2015, Mr. Piguet and Mr. Gerlach each were eligible to receive a bonus equal to 18% of the pool. Each of the Company's other executive officers was eligible to receive bonuses equal to 18% of the pool in 2016 and 2015. No non-equity incentive plan compensation payments were made to the Named Executive Officers for 2016 or 2015 because the Company's EBT for the period did not exceed the amount required for payment under the plan.

        The Company did not make any grants of stock options to the Named Executive Officers during fiscal 2016 or fiscal 2015.

OUTSTANDING EQUITY AWARDS
AT FISCAL YEAR-END

        There were no outstanding equity awards granted to the Named Executive Officers as of December 31, 2016.

        The Company does not have any employment agreements with any members of its executive management team, but has entered into confidentiality and non-competition agreements with such persons. These agreements generally provide that the executive will not solicit any other employee of the Company to leave the Company during the executive's employment with the Company and for two years following such employment, will not compete with the Company during the executive's employment and for one year thereafter, and will protect the proprietary information of the Company during and following such executive's employment.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Exchange Act requires that the Company's directors, executive officers and persons who own more than ten percent of the Company's Common Stock file initial reports of ownership of the Company's Common Stock and changes in such ownership with the Securities and Exchange Commission. To the Company's knowledge, based solely on a review of copies of forms submitted to the Company during and with respect to fiscal 2016 and on written representations from the Company's directors and executive officers, all required reports were filed on a timely basis during fiscal 2016.

RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The Audit Committee has selected RSM US LLP to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2017. It is the judgment of the Audit Committee that RSM US LLP has and will conduct its affairs in an appropriate manner and warranted selection as the Company's independent registered public accounting firm. While it is not required to do so, the Board of Directors is submitting the selection of RSM US LLP for ratification in order to ascertain the views of the Company's shareholders on this selection. If the selection is not ratified, the Audit Committee will reconsider its selection.

        A representative of RSM US LLP is expected to be present at the Annual Meeting of Shareholders and to be afforded an opportunity to make a statement or respond to questions during the meeting.

ADVISORY VOTE ON EXECUTIVE COMPENSATION

        The Company is asking its shareholders to provide advisory approval of the compensation of the Named Executive Officers included in this Proxy Statement, as the Company has described it in the "Executive Compensation" section. This vote is advisory and is not binding on the Company or the Compensation Committee of the Board of Directors. The Company believes its executive compensation practices, including the lack of employment agreements, change-in-control agreements or perquisites, demonstrate good governance practices and align the interests of the Company's executive officers and shareholders. The Company also believes that the compensation of the Named Executive Officers as disclosed in this Proxy Statement is significantly lower than the compensation paid to similar executive officers at companies similar to IKONICS due to the Company's relative low-cost location in Duluth, Minnesota, its historical pay practices, and its focus on pay equity among the Named Executive Officers.

        The Board of Directors recommends that shareholders approve the following advisory resolution:

        RESOLVED, that the compensation paid to the individuals identified in the Summary Compensation Table, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC, is hereby approved.

ADDITIONAL MATTERS

        The Annual Report of the Company for the year ended December 31, 2016, including financial statements, is being mailed with this Proxy Statement.

        Shareholder proposals intended to be presented at the 2018 Annual Meeting of Shareholders must be received by the Company at its principal executive office no later than November 24, 2017 for inclusion in the Proxy Statement for that meeting.

---

        As of the date of this Proxy Statement, management knows of no matters that will be presented for determination at the meeting other than those referred to herein. If any other matters properly come before the Annual Meeting calling for a vote of shareholders, it is intended that the shares of Common Stock represented by the proxies solicited by the Board of Directors will be voted by the persons named therein in accordance with their best judgment.
