<p>[QUOTE=&quot;rlm&#039;s cents, post: 520735, member: 7957&quot;]As for your lacquered coins, you may be looking for heat - and that does not necessarily mean boiling hot especially with flammable solvents.&nbsp; As a rule of thumb, for every 10° Celsius you raise the temp, the reaction speed doubles and in the case of dissolving, I would not be surprised if it quadruples.&nbsp; If 20° is normal temp, 60° would at least 16 times as fast.</p><p><br /></p><p>Caution - all solvent you are talking about become very volatile at those temps and acetone boils at 56° C.&nbsp; Xylene and toluene both boil above water and are probably better for lacquers.</p><p><br /></p><p>However, nothing will help a damaged coin.[/QUOTE]</p><p><br /></p>
