Fiber CPU's that act like ceramic ones

I was working under the impression that I needed to make sure I had at least a gram of gold in the end to get a bead of gold big enough to see and hold without loosing. Now it looks like 1/10 of a gram would be enough for a first try.

Even smaller are possible... http://goldrefiningforum.com/phpBB3/viewtopic.php?f=61&t=7056 :mrgreen:

Thanks Göran,

That should encourage me to get my first button now. I'm getting really impatient to see some results from my work. I never would have thought that one chip would make a visible bead of gold. The little torch was encouraging too. I guess if you are only melting that small amount of gold it doesn't take a real large torch. The charcoal was a good idea too. I think trying to use a cupel to melt my tiny amount of gold would soak up the heat quicker than the torch can produce. The only torch I have at the moment is a cheap plumber's torch which won't get the whole cupel glowing even with some ceramic wool insulation.

I currently have a tiny amount of crushed I.C. chips in a vial soaking in weak [stt]HCl[/stt] homemade nitric. I can see the gold in the very bottom of the vial so I know there is some there. This was just another test with some very tiny I.C.'s to see if they contained gold. All of my other tests have just been dumped together because I didn't think I could get anything to melt out of them until I got a much larger amount. Looks like I should have been keeping them less contaminated. I'll eventually recover that gold. Nothing was thrown away. Even the Q-tips from the tests have been saved.
