1. I'm not sure I'd advise throwing all the wheel weights in a pot and adding heat until the zinc, clips and steel weights float. The problem is that the bottom of the pot may go over 780F and melt the zinc which will give you oatmeal looking lead. Separate enough known lead wheel weights (I use diagonals and give them a cut/squeeze test). Get the lead melted and clean out all the clips and crap. Monitor the temp and keep it below 700F then add more wheel weights and continue to strain the clips, zinc and crap. 100 lbs won't take too long to process.
