[QUOTE="jon_m, post: 523291, member: 2232"] Copied your set up Dave, and melted my first gold. Thanks again for your video and explanations. Maybe with one burner I should have turned the crucible - looks like I started to melt it. Only put a couple of grams in for first go and had trouble deciding when the gold had melted, so burner was on for 12 to 13 minutes! ... and torch should have been further back?? Also appears I added too much borax, Had an extra blob of black come out, aside form that on the button. Dipped it into HCl from the mould but was it just too much borax that stopped it all from separating?
