I'm a newbie here, a lapidary whose muse is pushing her to explore metalsmithing, specificaly alloying some 14kt blue-green gold. I have a small oxy-propane torch, scale, files, buffer and the like - what else do I need? How do I stir the molten metal? How do I turn it into wire and sheet? I'm thinking about sand-casting a pendant setting - is this hard?
