Ladies and Gentlemen:

         In connection with the Registration Statement on Form S-8 under the
Securities Act of 1933, as amended (the "Registration Statement"), relating to
the registration of an additional 37,500 shares of Common Stock, par value $0.10
per share (the "Shares"), of IKONICS Corporation, a Minnesota corporation (the
"Company") under the IKONICS Corporation 1995 Stock Incentive Plan (the "Plan"),
we have examined such corporate records and other documents, including the
Registration Statement and the Plan, and have reviewed such matters of law as we
have deemed relevant hereto, and, based upon such examination and review, it is
our opinion that all necessary corporate action on the part of the Company has
been taken to authorize the issuance and sale of the Shares pursuant to the
Plan, and that, when issued and sold as contemplated in the Registration
Statement, the Shares will be legally and validly issued, fully paid and
nonassessable under the current laws of the State of Minnesota.

         We are admitted to the practice of law in the State of Minnesota and
the foregoing opinions are limited to the laws of that state and the federal
laws of the United States of America.

         We consent to the filing of this opinion as an exhibit to the
Registration Statement.

                                           Very truly yours,

                                           FAEGRE & BENSON LLP


                                           By:   /s/ W. Morgan Burns
