Develop a safe method for smelting and casting. No smoking( if you do) and Make Sure NO BEVERAGES anywhere close to lead pots. Being in Florida I try to cast in winter( if you can call it that) in garage with door open and large box fan to the side of pot blowing Out. Have some protective clothing such as shop apron, gloves, ( nomex flight gloves are great)jeans, leather shoes ,clear face shield and hat/ cap. You do not want a visit from the “ tinsel fairy”. Been casting since late 70’s and keep Pb in metal ammo cans. I only size with RCBS sizer and dies since 70’s.
