Thanks, I am aware of this I have a tinny little bead of gold that I will test on to see if I can get it dissolved in solution. The starting list will be 1/4 tea spoon of copper sulfate, then I will add 3 tea spoons of sodium thiosulfate, then i will add 3 tea spoons ammonium sulfate and then I will use ammonia as the liquid no water will be added. Will let it sit for a few days then will check the result and see if the bead is reducing in size.
