So a while back I bought 70# of lead. This was an unfortunate e-bay purchase. The seller marketed the lead as "Wheel weights. Fluxed. Dirty work is done for you."
It came in lyman 1# ingots and 1/2# pan ingots. The lyman ingots were as clean as expected. The pan ingots, however... They tell a different story. I'm hoping someone can help me identify the garbage in these ingots.
The melt forms a gold hue on top which, for the life of me, I can't clear up. After fluxing, the surface becomes a deep purple color. Tonight on the second flux, the surface turned dark blue. After I cleared that out, the gold returned. Despite several attempts (and a lot of time) flux/skimming doesn't clear it out.
Any idea what this crap is in the lead? I'm able to pour fairly decent ingots as my RCBS ladle doesn't let much of the gold stuff through. Fluxing of the poured ingots clears everything out.
Any help is appreciated. I'm getting close to just reselling this stuff to someone else.
Thanks!
