Finally had a successful ingot pour. I have tried a couple of shallow graphite molds, but no luck. Seems the graphite sucks the heat out of the molten sterling really fast which kept giving me a partially formed ingot with a blob on top. Went back to the first video I saw on YouTube that inspired this project and decided to try a simple one time wood mold.
Poured almost perfect on the first try. Cleaned it up with a wire brush on the drill, then various grits of fine sandpaper, some 000 synthetic steel wool, and a light polish with the drill again and a buffing wheel. Two old junk sterling fork prong ends plus some other bits turned into a nice chunk at 46.15 grams - worth $33.29 as of tonight (not including TFL added value). 76,91,46,0,B,.21
