Hi,
I'm getting married next week (hence my panic), and we planned to sand cast our own wedding rings.
I conveniently work for a furnace company, who let me use a furnace to melt the gold, and the first ring turned out perfectly.
10g of10ct gold in a 1100*C furnace with a dash of borax powder.
I had to order more gold for the second ring, and this time, somehow, it looks like the gold has fused with the borax...(or something?!) and I can't separate it. It turned into black glassy mass that filled and set in my crucible.
I've had my blowtorch on it this evening and I can see the gold glinting, but it just won't pour, and I'm frightened to add more borax.
I have until Friday to separate it as that's when I have access to the furnace.
Please help! I'm desperate!
