<p>[QUOTE=&quot;desertgem, post: 551787, member: 15199&quot;]Ruben, acetone would not considered a &quot;dip&quot; type of chemical for the process that NCG, PCGS mention. The &quot;Dip&quot; they refer to is a chemical reactive to metal, which acetone under normal conditions is not.</p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p>Ruben, the process uses Baking soda, aluminum foil, table salt, and water at 60 deg. Centigrade.&nbsp; No electrical connection needed. How are the &quot;kids&quot; going to be affected?</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
