When I was a kid, I used a single gas burner & cast iron lead pot that held about 25# - worked fine, but had to use a ladle that I made from an iron pipe cap & old threaded handle. For the past 35 years I've been using a Lee lead pot with the bottom pour spout - much cleaner, faster & much more uniform results than with a pot & dipper.
With a little practice & a good, stout thumbnail, you can easily ID & separate out the zinc weights. The tape-on wheel weights are nearly pure lead & have more value for casting muzzleloader roundballs.
