<p>[QUOTE=&quot;desertgem, post: 1813258, member: 15199&quot;]A minority scientific article has said that copper in acetone in the presence of strong light and humidity can&nbsp; react producing corrosion. I tried to replicate the reaction, but never got the result they claimed. I put acetone , bright copper coins, and water vapor together under bright sunlight for a week and got no reaction. FWIW.</p><p><br /></p><p>However, I didn&#039;t rip off an existing patina and expose &#039;naked&#039; highly reactive copper metal. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
