I, Jon Gerlach, certify that:

1. I have reviewed this quarterly report on Form 10-QSB 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. The registrant's other certifying officer and I are 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 we have:

a) designed such disclosure controls and procedures, or caused
such disclosure controls and procedures to be designed under
our supervision, to ensure that material information relating
to the registrant, including its consolidated subsidiaries, is
made known to us 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 our
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 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. The registrant's other certifying officer and I have disclosed, based
on our 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.
