I don’t think you will be able to melt the silver and gold , and retrieve
the gold flakes. It will be too difficult to get the right temperature to
melt the silver, and it has already gotten into the pores of the gold
flakes. Also, you will probably melt the gold also.
What you might try, if you’re comfortable working with acid, it to soak the
articles in nitric acid until the silver dissolves. This will take a while,
and please observe the cautions and safety procedures, using acid.
#10, is the size of the gold flake. It is about the smallest size flake I
like to use, when making nugget jewelry.
I hope this has been of help, and I’m sure other members will add their
