The ingot on the right was cast from range scrap. The center ingot was cast from scrap lead pipes. The ingot on the left was cast from clean roof sheet lead. Not sure if it shows in the picture, but the roof lead ingot is very shiny while the others are dull. Is that purely from the composition of the lead or did I unknowingly do something different between the smelting sessions?
