I'm new to this and have read plenty but have a question.
I have melted down a bunch of scrap lead and ww. I have kept the ww seperate from the other stff I have made into ingots. I also purchased a good quantity of monotype. I recently have attempted to add some of the monotype (BHN29) to the ww and when fluxing I get a lot of dark gray to black dross. It is crumbly and dry almost like dirt but is rather heavy. I have fluxed the ww once prior and never got this quantity or type of dross before. I am adding about 1 # of monotype to 9# of ww and I'm getting a good quantity of this dross. I find it hard to believe that this is dirt and impurities from 1# of monotype. I have tried to flux it back in to no avail. I hope this isn't antimony I'm losing. I have used the Franklin CleanCast Lead Fluxing Compound and some Type Clean flux with similar results. I have cast some boolits from an old Saeco SWC mold that look real nice. They have tested out to BHN14.2 using the Lee tester. Does anyone have any ideas of what I'm running into?
