I got some of the cheap metal muffin pans (not teflon) for $2 each. I scuffed them up with some sandpaper, dipped them in saltwater and let them sit outside for a week. They developed a nice coating of rust. I then sprayed them with some graphite spray. The ingots drop right out of them. 5 of them will just about empty my smelting pot.
I also made some from angle iron that work ok. My latest experiment was a stainless mud pan from lowes. I put a piece of angle iron in it as a divider. it makes 2 5lb ingots when you pour about an inch deep.
