<p>[QUOTE=&quot;Delmer, post: 216431, member: 8219&quot;]More heat had the effect of BOILING whatever is on the surface and further turning it to little globs of crust.&nbsp; The coating is probably a couple dozen molecules thick It turned orange as it boiled and the flow of my gas caused the goop to push to the top of the coin and pool some.&nbsp; Now the coin looks a LIGHTER shade of aged copper in the middle and darker around the rim where the puuls of liquid settled. Under close inspection the dark scum flakes off a bit when rubbed hard.&nbsp; Probably give me cancer of something.</p><p><br /></p><p>Theres no more natural light here, it makes the result look darker.</p><p><br /></p><p>I bet if I used a KILN the coating would be black and even, like his picture.</p><p><br /></p><p>what a world..[/QUOTE]</p><p><br /></p>
