POWER OF ATTORNEY
EX-24

I, Claude P. Piguet, hereby authorize and designate each of
W. Morgan Burns, Steven J. Conley and Amra Hoso, signing singly,
as my true and lawful attorney-in-fact to:

(1) execute for and on my behalf, in my capacity as an
 officer and/or director of Ikonics Corporation (the "Company"),
Forms 3, 4 and 5 in accordance with Section 16(a) of the Securities
Exchange Act of 1934 (the "Exchange Act") and the rules and
regulations promulgated thereunder;

(2) do and perform any and all acts for and on my behalf which
may be necessary or desirable to complete and execute any such
Form 3, 4 or 5 and timely file such form with the Securities and
Exchange Commission, any stock exchange or similar authority, and
the National Association of Securities Dealers; and

(3) take any other action of any type whatsoever in connection
with the foregoing which, in the opinion of such attorney-in-fact,
may be to my benefit, in my best interest, or legally required of me,
it being understood that the statements executed by such attorney-in-fact
on my behalf pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may
approve in such attorney-in-fact's discretion.

I hereby further grant to each such attorney-in-fact full power
and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any
of the rights and powers herein granted, as fully to all intents
and purposes as I might or could do if personally present, with full
power of substitutes or revocation, hereby ratifying and confirming
all that such attorney-in-fact, or such attorney-in-fact's substitute or
substitutes, shall lawfully do or cause to be done by virtue of this
Power of Attorney and the rights and powers herein granted.
I hereby acknowledge that the foregoing attorneys-in-fact, in serving in
such capacity at my request, are not assuming, nor is the Company
assuming, any of my responsibilities to comply with Section 16
of the Exchange Act.

This Power of Attorney shall remain in full force and effect until
I am no longer required to file Forms 3, 4 and 5 with respect to my
holdings of and transactions in securities issued by the Company,
unless earlier revoked by me in a signed writing delivered to the foregoing
attorneys-in-fact.

IN WITNESS WHEREOF, I have caused this Power of Attorney to be duly
executed as of this 7th day of January, 2021.

/s/ Claude P. Piguet
