We were piddling around at work in our scrap area, and I came across a pallet of this. They were originally rings before I cut them up. Im guessing they are pure Pb, but not 100% sure on that. They are from some old equipment we used to use (sulfuric acid plant). I grabbed 6 of the rings and im guessing they weighed in at about 10 lbs each. There are at least 30-40 more with a bunch of other scrap so probably 500 or so lbs! Dont have any way to test them to determine content though. They sure melt pretty with very little dross despite not fluxing at all. The pic with the dross is after casting 30+ lbs of ingots.
Guns have only two enemies: rust and politicians!
