I just turned a 50# roll of flashing into ingots. I was kind of surprised that when I opened up the thing, it was pretty shiny. Everything seemed to pour OK and looked good, but is there any zinc on new lead flashing? I have another roll and don't want to waste my time. I'll cut open an ingot and use my LEE hardness tester in a day or two to see what it looks like. Anybody know if there is a film of zinc on the stuff or is it just the oil that keeps it shiny??
