I haven't found a problem with the zinc melting, as it takes awhile for the melt to come up to temperature. I keep my Lyman thermometer in the pot, and as it gets up to temp I make sure I stir the melt believe around 650�, where zinc melts at 787�, I am able to skim whole weights off the top. I do presort my wheel weights which is a tedious job, but helps insure I don't melt any undesirable metals.
Creeker, I love your ingot molds, but my back aches looking at them on the ground.
