I went crazy at the local thrift store and bought what I thought was cast pewter plates. Well, the first piece won't melt so I am guessing I bought a bunch of cast aluminum that looks like pewter. I know they used to cast real pewter into tableware so I was thinking that was something like that. I think I wasted $12.00. I did buy a tankard that was marked pewter and it gave me an ingot the size of a one-pound lead ingot.
