<p>[QUOTE=&quot;SuperDave, post: 2359770, member: 1892&quot;]It&#039;s pretty trivial to make copper the catalyst in a <b>seriously</b> exothermic oxidation of acetone (enough to make the preheated copper lose none of that temperature and stay red-hot), without the acetone actually igniting. That should be a hint even to the non-chemist (raises hand) of the potential relationship between copper and acetone.</p><p><br /></p><p>And since the article we&#039;re both talking about publishes specific procedure, it&#039;s easy to duplicate itself with or without peer review. More here:</p><p><br /></p><p><a href="http://jes.ecsdl.org/content/147/11/4125.abstract" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://jes.ecsdl.org/content/147/11/4125.abstract" rel="nofollow">http://jes.ecsdl.org/content/147/11/4125.abstract</a></p><p><br /></p><p>None of this makes me unwilling to use acetone on copper. Far from it. Conservation is about <i>exacting</i> procedure, and avoiding light when employing acetone/copper isn&#039;t difficult.</p><p><br /></p><p>I&#039;m going to specifically attempt to duplicate this myself during 2016, but I&#039;ve a lot of pies in the oven at the moment so it&#039;s just another entry on the priority list.[/QUOTE]</p><p><br /></p>
