youd get a kick out of my favorite alloy. Its an alloy that goes about 16bhn and to be honest i dont have a clue how to duplicate it. A couple years back my pole barn that i loaded in burned to the ground. I had probably a tons of lead and a couple hundred lbs of tin. The lead was a hodgepodge of pure, ww, linotype, and monotype. The barn had a dirt floor and after the burned junk was hauled out i found about half the area of the barn had a laver of melted lead. Floor was dirt so it had rock and dirt imbedded in it. It took me all summer but i smelted it all back down. I did it in 100 lb batches and after i was done i then combined equal ammouts of each batch into new batches and did it all over again and then to make sure it was consistant i did it a third time. Ive never had an alloy that casted as nice as this alloy. I ended up recovering about what i figured was 1400 lbs. Ive got probably half that left now but once its gone its gone and i find myself being stingy with it just like i am with tin or linotype
