Melting down badly corroded lead shot
A while back I was given around 40 to 50 pounds of fairly badly corroded lead shot. It had been used in scuba back packs as part of the weight distribution efforts needed by those that use dry suits to avoid a sore back from an overly heavy weight belt around the waist. The corrosion on this fairly large shot is actually a sort of tan color and fairly well polished from shaking around in the back pack during use. The color and nature of the corrosion likely having something to do with the salty ocean water.
Along with this I've also got roughly another 40 lbs of old shot which just sat around too long in some old shot bags. This shot has a lot of the loose white lead oxide (I'm guessing that's what it is) on it. It too I'd like to melt down and ingot'ize.
I'd like to melt this down to ingots first then eventually cast up some boolits with it. But I'm wondering if there's any issues with the corrosion on the lead. Any additional steps or personal protection any of you have found are needed for something like this? The white lead corrosion dusts off and floats around a lot so the plan is to wear a good dust mask and do the handling with some gentleness to limit the "flight" of the dust and hold it down to a smaller area. But once into the melting pot do I need to take any special steps to get some good lead from this stuff?
