How do I make my own rose gold?
I need to make a tiny bit of Everose gold for microwelding to Rolexes.
The recipe is 1g Au, 0.3g Cu and 0.02g Pt
I snipped 0.3g of copper from a speaker cable. Put it in a ceramic melting dish with borax. But couldn’t for the life of me get it to melt the way I effortlessly can gold or silver. The copper sort of fused a little to each other but wouldn’t collapse to form a molten bead. Even when the dish was glowing red.
Is there a particular way to incorporate copper into a gold alloy?
I’m very familiar with melting gold and silver. First time handling copper
