<p>[QUOTE=&quot;sand, post: 8326247, member: 118540&quot;]Is acetone safe, for a bronze coin with a patina? Would acetone damage or modify the patina? I don&#039;t know.</p><p>I think acetone is safe, for silver coins that have no tone.</p><p>But, I&#039;m not very knowledgeable about acetone.</p><p>I may have heard, of heating a coin in an oven for a while, to melt the wax. I guess, you could heat the coin, let the wax drip off, then flip the coin over, heat the coin again, and let the wax drip off of the other side, and so on. But, I don&#039;t know, if that&#039;s safe for the coin, either. I&#039;m guessing that, one has to be careful, not to overheat the coin, by turning the oven temperature up too high. And, of course, be careful not to burn your hand, on the hot coin, unless it&#039;s the One Coin (Lord Of The Rings reference).</p><p>[MEDIA=youtube]K51yvpSX2mA[/MEDIA]</p><p>Maybe putting the coin in hot or boiling water, to melt the wax, would be safer for the person doing it. As the coin flips around in the hot water, the wax would melt, and perhaps be removed from the coin by friction with the water, or by dissolving with the water. And then, dry the coin in an oven, to remove all traces of water. I may have heard, of someone doing that. I don&#039;t know.[/QUOTE]</p><p><br /></p>
