Hi,
I got a bullet casting kit for christmas, so today I was melting down lead that I got for free. I am almost positive that it was pure lead, and I had 125 pounds. I was melting it in a big pot on the side burner of my BBQ to pour ingots, and if I let the lead sit for a while the surface turned blue and purple? Is this normal? I just stirred it up and kept casting.
Thanks
