                                 CERTIFICATIONS

I, William C. Ulland, certify that:

         1. I have reviewed this quarterly report on Form 10-Q of IKONICS
Corporation;

         2. Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this report;

         3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as
of, and for, the periods presented in this report;

         4. I am responsible for establishing and maintaining disclosure
controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e)) for the registrant and I have:

            a) designed such disclosure controls and procedures, or caused such
       disclosure controls and procedures to be designed under my supervision,
       to ensure that material information relating to the registrant, including
       its consolidated subsidiaries, is made known to me by others within those
       entities, particularly during the period in which this report is being
       prepared;

            b) evaluated the effectiveness of the registrant's disclosure
       controls and procedures and presented in this report my conclusions about
       the effectiveness of the disclosure controls and procedures, as of the
       end of the period covered by this report based on such evaluation; and

            c) disclosed in this report any change in the registrant's internal
       control over financial reporting (as defined in Exchange Act Rules
       13a-15(f) and 15d-15(f)) that occurred during the registrant's most
       recent



<PAGE>

       fiscal quarter (the registrant's fourth fiscal quarter in the case
       of an annual report) that has materially affected, or is reasonably
       likely to materially affect, the registrant's internal control over
       financial reporting.

       5. I have disclosed, based on my most recent evaluation of internal
control over financial reporting, to the registrant's auditors and the audit
committee of the registrant's board of directors (or persons performing the
equivalent functions):

           a) all significant deficiencies and material weaknesses in the design
       or operation of internal control over financial reporting which are
       reasonably likely to adversely affect the registrant's ability to record,
       process, summarize and report financial information; and

           b) any fraud, whether or not material, that involves management or
       other employees who have a significant role in the registrant's internal
       control over financial reporting.
