A friend of mine has a large container of seals that were used to seal railway cars after the doors were shut. It looks and feels like lead but seems a bit harder. I plan to test it with my LBT hardness tester. I really would like to know what is in the seals before I try melting them or shooting them. Do any of you know what is in these seals?
