I picked up an old cast iron Dutch oven at the recycling/exchange center. It would be just the right size for smelting, but it is porcelain coated. Has anyone actually tried melting lead in a porcelain coated pot? I am curious what would happen to the porcelain coating. It is already chipped off in spots and it is definitely cast iron not steel or aluminum (it”s magnetic). If the porcelain chipped off it would just float to the surface I would think and wouldn’t affect the lead. Anyone got any first hand experience?
