lead sticks to muffin pans and they end up with holes in them from dropping them on the floor to get the ingots out.Farm and Ranch stores,sporting goods, camping, cabelas etc.. have cast iron corn bread or muffin molds for cooking over fires, you can get wedge shapes, fish shapes, mine look like little ears of corn and weigh about 3/4 lb, there are 4 to 6 holes in a mold , they don't stick and last forever. I melt down scrap in the garage coal stove and have clean ingots to cast in the comfort of my reloading room during cold season.The old two handed army surplus stainless spoon with holes works great if melting wheel weights, gets all the metal clips out in one pass, and no do not pour out of the pot
