The short answer is almost none. Fully cured epoxy is one of the most
solvent resistant polymer systems known. It can be softened by very
strong, but difficult to handle, solvents like dimethylformamide, but
because of its high molecular weight and inherent chemical resistance
it is practically not removable by chemical means.

http://www.hisglassworks.com/pages/attack.html seem to think
otherwise. A hot air gun can also heat epoxy to over 225 C which will
soften it to the consistency of brown sugar.
