I have just begun casting some lead round balls with a .375 Lee mould and a Lee melter, the smaller model that I think holds 4 lbs, not a bottom pour melter. I am using some roofing lead which has been in my garage for about 30 years rolled up in the corner. It melts down quick, using a roughly 700 degree setting, and I drop a very small piece of beeswax in to flux it, and then skim the impurities off the top. The question - I seem to get a lot of lead oxide on top of the melted lead that would require a lot of skimming, thereby wasting a lot of lead. Is that normal or is my temp to hot, not hot enough, etc?
Thanks in advance.
