<p>[QUOTE=&quot;Kentucky, post: 2853782, member: 33176&quot;]Yeah, but how do you do that...Beilstein test.&nbsp; Heat a copper wire (fairly thick or it will just form a bead in the flame) with a lighter of some sort.&nbsp; Touch the hot copper wire to a piece of the plastic to be tested (of course this is destructive, so either use a scrap piece, trim a sliver off, etc.) so that it melts onto the copper.&nbsp; Heat the copper wire in the flame again and look for a green coloration.&nbsp; 100% certain, no, there are some other materials that will test positive, but you shouldn&#039;t encounter them.[/QUOTE]</p><p><br /></p>
