I smelt all the lead I get in a large cast iron pot and flux with saw dust 2 times. The pot holds about 70 pounds +\-
I first make 25 pound bricks just for the ease but when I need to make smaller pucks I melt one or two bricks down and flux again but this time I add a candle (heard this was good) so it gets cleaned a 3rd time.
Well I recently made about 75 pounds of 1/2 pound pucks and left them in a 5gallon bucket on my porch where I do my casting.
I noticed severe color variations after about 3 months in the pucks. Yes I did manage to get some liquid in with them and I know that the white residue is from that. I found what looks like rust on some of them.
The lead is sourced from old telephone junctions so I know it has a tin content to them or at least that is what I read.
The pics are all from the same bucket and smelting session so any input would help.
