<p>[QUOTE=&quot;Kentucky, post: 7987615, member: 33176&quot;]OK, to do the Beilstein test, you can use a disposable cigarette lighter or pretty much any source of flame (I&#039;ve used the lighter, but never tried a candle, though I bet it would work).&nbsp; If you don&#039;t want to sacrifice the flip, cut a small sliver from an edge.&nbsp; Use a copper wire with enough diameter that you don&#039;t melt it in the flame.&nbsp; Heat the copper wire up hot and touch it to the plastic.&nbsp; Return it to the flame and look for green when it burns.&nbsp; The green indicates copper chloride formed from the copper in the wire and the chlorine in the PVC (Poly Vinyl Chloride).&nbsp; If there is no chlorine, it won&#039;t turn green.&nbsp; PET is the preferred material for flips, and is the film that is found on any of the fold-over cardboard 2x2&#039;s I have ever seen.&nbsp; PET contains no chlorine.&nbsp; PM me if you want to know any more.[/QUOTE]</p><p><br /></p>
