I noted a lot of folks saying they use muffin tins for ingot molds and I do have some ingots cast from muffin pans by someone else. I've got 2000# of lead to melt down so I thought I'd give some muffin tins from walmart a try. I ended up with 48 ingots securely attached in the muffin tins. Had to cut the muffin tin off with side cutters.
Any thoughts on where I went wrong, any advice is greatly appreciated.
Thanks,
Rick
