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

I found an interesting setup on EBay that requires no crucible and will give uniformity to your ingots. If you can craft one of these you'll be stylin.

Dale...thanks for the link. I've seen that guy's vids. Caught the tail end of one of his auctions and just missed out on getting a bid in on time.
He has his contact information further down on that link. He sounds very approachable and will probably hook you up on a special order.
As a ex-silversmith the graphite mold Must be hot and I mean hot when pour.
Like the idea of wood thou, never did that!
