Did my best today. 300 pounds of zinc contaminated alloy. Respirator was a necessity. Stayed upwind, but got an ocasional tingle around the eyes, no repiratory issues though. Worked as advertised. Lost about 15 pounds of dross. I suspect some of that was lead as I was trying for super clean lead.
When to stop fluxing with sulphur was my question. When I started having molten sulphur nuggets on the surface with no reaction, I fluxed with sawdust and wax, skimmed and poured into ingots. I’ll try casting and shot dripping this week. Report to follow.
SO/ safety observer served hot cocoa during breaks. Hands washed, etc...(34 degrees)
