Two summers ago, I "Refined" about 150 pounds of wheel weights of mine and about 80 pounds for my best friend into one pound ingots. At the same time I had about 50 pounds of old lead drain lines and the best friend had about the same of used lead roof flashing. The flashing came out at almost 50 ingots, The drain lines had so much "stuff" caked inside I only got 35 ingots. All the s
"slag" and ww clips went into a 3 pound coffee can and was given to the scrap yard to send in with their lead to be recycled (that way the EPA can't say I contaminated our local land fill!)
I let the ingots cool and stamp them with "LEAD" or "WW" so I know which alloy they are. I also have used "20 over 1" and "TYPE" to keep those alloys straight also.
It used to be easy to stop at the service stations and tire stores on the way home on Tuesdays and get all the wheel weights you could want. Now you are treated like a thief in the night, or they want to charge you 50 cents a pound for mixed zinc weights with used oil poured over them so you can't tell what they are.
It is difficult to be such a good citizen, and do my part for recycling! But I try!
