Banana nut are probably bread pans, also known as loaf pans. Mom’s pans will probably make about a three pound alloy muffin. Wal*mart has some "Mini Loaf Pans" that might make good Ingot molds. I have not tried them as they have the same non stick surface, that was on a muffin pan I bought and I could not get the alloy out of that one. Others, however have reported success. It has also been suggested that rust is the secret to the ingots releasing. Try garage sale muffin pans. Also if you are really serious about your ingot molds: http://www.mifco.com/ingot.htm
