I was basing it on what I paid for a much smaller quantity of

The unanswered question is, can I replenish the gold in the non-cyanide

I've added a bit of gold to mine successfully. I _suspect_ the
solution is mostly aqua regia.


What is "mostly" Aqua Regia?

Aqua Regia has a very limited life span.

And try plating precious metal in Aqua Regia. Do you know what happens? Look
