<p>[QUOTE=&quot;desertgem, post: 1535726, member: 15199&quot;]From what I read, some of the plated bars will test Ok with the low cost jewelry probes, if the plate is thick enough. Some of the testing machines lack resolution for accurate determinations. I haven&#039;t read anything about the magnetic properties, so I can&#039;t answer that, but yes if tungsten had a lower melting point that could be cast, we would have a large numismatic problem. Education as to what counterfeiting of metal is occurring is the first major step, and finding webpages that advertise it may give hints what to watch out for. People are always going to buy it on Craigslist from &quot;someone who doesn&#039;t know its value&quot; for half the price of gold , and then bemoan their fate.</p><p><br /></p><p>I don&#039;t know the actual cost of wolfram ( ore) or the chemicals involved. I suspect much&nbsp; less than the processing of gold with cyanide process, but no actual figures in my head.[/QUOTE]</p><p><br /></p>
