While reading "Big Fat Book of the .45 ACP"
I got to the part where you cook up lead. There I learnt "dross" will remove antimony and tin if scooped out. This part usually confused me. I thought once mixed tin and antimony was locked in the lead. I come from silver back ground. Like once you got copper in silver (sterling or coin) it's in there and you need acid to purify it to .999 pure silver. So if the pot has a bottom drain all the crap like fat will remain on the top.

Couldn't find it on DVD, huh? 😁

you need to 'flux and stir' before removing the 'dross'

Many years ago, while casting bullets, I made the rookie mistake of not making sure the lead was COMPLETELY dry when I added it to the pot. I was half-way across the basement before I realized what had happened. I had one small speck of lead on my cheek: Most of the lead spatter was on the back of my shirt. My reflexes were pretty good back then.

That I knew but I didn't know Tin/Antimony and the likes got drawn out of the lead and in to the dross to be scooped out.

Check out the castboolits web site. They have more info on lead casting than you will ever need . As a general rule of thumb , ordinary fluxing does not draw out tin etc .For the definitive book on the subject look for the book " from ingot to target" by Glen E. Frixell.

I'll have to keep an eye out for Glen E. Fryxell's book.
