Wow, everyone great advice, and pics makes this an invaluable thread for smelting; at least to me.
To be safe, after reading about moisture in this thread, I held off adding some scrap that had sand in it because it still retained moisture. I'll take care of that before smelting it. That could have been disastrous.
I'll re-read through this thread several times and find a way to get to it easily for reference. For new guys like myself, this is seriously helpful information.
Things like: fluxing before scooping out the boolit cases; maximum melt point (750*) aim for 700* to prevent alloy vaporization(didn't have any idea there can be a loss of lead from it); avoiding adding moisture to a molten mix.
Conditor, this surprised me when you said, "Harder alloyed metals will melt at lower temperatures than pure lead." And thanks for your pics, they gave me a couple ideas, like your wisk.
Is this thread worthy of being stickied?
