I stopped by the thrift store today and looked for an ingot mold and was about to give up when I spotted this. I have never seen one made this way but it works like a champ. It is stamped steel welded to the frame. I burned the crude out with the propane burner and it cast some nice ingots that fell right out. They weigh between 1 1/2 and 1 3/4 pounds each. They cool quicker because they have more seperation than normal muffin tins. It hangs up out of the way too.
