What do you do with the slag you skim off the top of your lead after you flux it? I understand lead oxide is hazardous and I don't want to be irresponsible with it. As an aside, I understand what fluxing is supposed to do, but it sure seems to create a lot of that slag. I also understand that having the lead too hot will cause oxidation but would appreciate any other comments on how to best handle melting and mixing lead alloys. Lastly, my Lee melter has the bottom pour feature but it keeps plugging up. I think the antimony doesn't stay completely mixed and solidifies in the opening. Any comments or suggestions?
