Hello, I have been separating my electronic scrap and I find I have a lot of copper stuck in with aluminum in my mix metal bin. One of the things I want to do is try my hand at jewellery making since I already do lapidary work and have quite a few stones that need to be mounted. I read up on Nordic gold and think it would be a good way to use the Copper/Aluminum mixes to start testing my pouring/moulding. Has anybody played around with it? It's hard to get accurate weight of each metals from those mixed pieces and I'm wondering how close to the ratios I have to be?
