Great info guys, now how do you get the rest of the impurities out of the lead, I was told that candle wax is the way to go, but never tried it so, not too sure how to? I always just melt it get all the GUNK floating ontop, let it cool and then brush that off and then reheat and pour, If any of you knows how to use the candle thingy, would be appreciated if you could tell me how, also I forgot to ask, does the candle wax affect the lead in anyway (perhaps smoother on the pour or shinnier when poured)?
