Good advise so far, but one thing that caught my eye was the poster who said he used an aluminum pot to melt lead. Bad idea! Aluminum pots will eventually fail and you definitely do NOT want a pot full of molten lead pouring out anywhere (especially near you)! Get a cast iron or steel pot for melting raw scrap lead. You can cut the top off a 20 lb. propane tank and use that as a smelting pot. There is a LOT of information on the "Cast Boolit" site. Be prepared for a lot of reading.
