<p>[QUOTE=&quot;GDJMSP, post: 212527, member: 112&quot;]Well, I&#039;m no chemist. But I know what my eyes tell me when they see something. And I&#039;ve seen copper coins dipped in acetone for anywhere from 5 seconds to 60 seconds in ordinary room lighting turn just about every color of the rainbow. No they don&#039;t all turn colors right away, in fact they don&#039;t all turn colors - but the vast majority of them do - some sooner and some later.</p><p><br /></p><p>So, I don&#039;t recommend dipping copper coins in acetone. Take it for what&#039;s it worth.[/QUOTE]</p><p><br /></p>
