I finally just said "To heck with it." and smelted my first batch of range lead. After removing the bullet jackets and dirt I decided to flux the remainder with a little sawdust and parafin. FLAMES!! and LOTS OF SMOKE, I mean LOTS OF SMOKE. I thought for sure I was busted at that point, but no the fire department didn't show up. Cool I survived that one.
Now for the questions. There was a scum of silvery stuff on the top of the pot. I couldn't seem to get it to mix with the rest of the lead. Am I not fluxing enought or was the mixture to cold? I put a thermometer in the brew and it read 600 F. I don't know if it is calibrated or not, nor do I know how to check it.
I do have a dozen muffin ingots however.
