Zinc melts at 787 degrees. If you're melting the stick-ons, they might not melt at 650 degrees, since they're nearly pure lead. I keep my melt/pot temp @ 750 to make sure everything melts fast, AND the melt/alloy is hot enough to flux properly. 650 is not hot enough for the flux to return the lead oxides to be returned to the metallic state.
