<p>[QUOTE=&quot;Kentucky, post: 1660445, member: 33176&quot;]Things don&#039;t happen for no reason.&nbsp; The reason you would get a green flame from heating a copper wire is the presence of a copper halide.&nbsp; The appearance of the green has to indicate a halide, and the most common halide is chloride from something like PVC.&nbsp; Don&#039;t know what other chlorinated polymers might be in your zip-lock, but contamination from your fingers could put some sodium chloride on the wire.&nbsp; This is a standard chemical test.[/QUOTE]</p><p><br /></p>
