Ok guys, i use range scrapthat i smelt. I flux 2-3 times with pine sawdust and tea candles. The ingots look good but when i put it in my casting pot i flux again and cast. Problem is now i get these hard crusty chunks making inclusions in my boolits. Sometimes its just stuck to the outside and i can just scratch it off with no pitting. Ive tried fluxing my lead pot several times per session and it looked like chrome glass on top but still get quite a few inclusions. Any pointers or helpful hints? Thx all
