Hey everyone! New here and to refining. I inquarted this gold with 999 silver 4:1 and should have about 34g +/- after refining. I bathed the gold in nitric solution 60/40 six times and once just nitric itself, then boiled and rinsed. When melting, it started to melt fine, then stopped, got red hot, but refused to liquify. I used 2 propane torches with direct heat, as well as attempted to melt it in a kiln, with no success. This is the gold that did melt, but what is the crumbly stuff that won't melt?
