Ah? So I have to flux the lead, even though I'm not working with an alloy? Should i just toss in a pinch of beeswax, and let it smoke? (I have tons of it on hand) What the heck is in commercial flux? Will fluxing bring all impurities to the surface? I guess I shouldn't worry to much about the lead oxide, just dip from underneath it.
I think you guys may have answered my question as to the heat issue. I know I didn't get up to aluminum melting temps, but I think that my mold and the melting pot were too hot. The bullets were definitely a pale, frosty grey color. I had to keep the mold fairly hot or I got wrinkled bullets. Only by leaving it on the edge of the flame was I able to eliminate wrinkles.
