I've been going through the forums here and in other groups, trying to find a simple answer, but not having any luck. (I usually try to find answers on my own, before “going to the boards.")
I know that clip-on wheel weights are often made of zinc, and I've read a lot about how to cull them when smelting, but I can't find out whether stick-on WW's also come in zinc (or steel or anything else)?
I have about 60 lbs of stick-ons and as I'm going through them I've found a bunch of shiny ones. That might be because they were scraped and the surface metal hasn't oxidized, yet. But if there are metals other than the almost-pure lead you find in stick-ons, I'd like to seperate it as soon as it's discovered.
