<p>[QUOTE=&quot;Kentucky, post: 2210972, member: 33176&quot;]However I respect your opinion and &quot;There are more things in coins than can be explained by simple-minded chemistry&quot;.</p><p><br /></p><p>One of the things about the test is the necessity of the copper wire.&nbsp; At a high temperature, the copper or copper oxide reacts with the plastic to form copper chlorides.&nbsp; Stainless steel won&#039;t form these compounds.&nbsp; There can be false positives with some nitrogen containing materials which are not common in plastics.&nbsp; I was concerned that not all households might have a butane lighter, but it is hard for me to conceive of a household that can&#039;t come up with a piece of copper wire.&nbsp; BTW, try some &quot;stuff&quot; on a copper wire and see if you get green.&nbsp; I don&#039;t think you will.[/QUOTE]</p><p><br /></p>
