<p>[QUOTE=&quot;dennis5151, post: 4505430, member: 90596&quot;]Short story...….&nbsp; I worked at a foundry and we experimented with vacuum lost wax casting.&nbsp; Sure, perhaps only one in three hundred are &quot;perfect&quot; but that is all it takes when you are dealing with high dollar items.&nbsp; The bad items can be re-melted.&nbsp; After experimenting with high vacuum casting, I am willing to bet <b>most</b> people can be fooled if they are using a standard loop.&nbsp; Of course, graders are specialist, why else shell out money for an opinion?&nbsp; Also, once slabbed, I guess it is beyond question unless re-evaluated for some reason.&nbsp; Interesting foundry fact, tungsten and gold have the same specific gravity.[/QUOTE]</p><p><br /></p>
