Good morning everyone!
When I was melting down range lead over the weekend and casting ingots, I put aside a few ingots that had a different coloring in a few spots. I picked up some muriatic acid today and put a drop on those discolored spots and got an instant, vigorous fizzle. Are there other "contaminants" that could be found in range scrap lead, other than zinc, that could cause a reaction like that? I am wondering if I should toss those 6 ingots or if here could just be something else in them that I can simply flux out on the next melt (something other than zinc).
Thanks in advance for the casting-chemistry lesson!
Mike
