I periodically drop by my local scrap yard to peek into their lead drums. I primarily look for tin or pure Pb as I use range lead for the bulk of casting. Today, aside from about half a roll of solder, everything else looked uninteresting. Then a ingot caught my eye. It was made with a soup can, and the top looked.....weird. As if the can had been filled by slowly dripping the lead into it instead of poured. There were at least 5-6 other similar ingots, each weighing 2-3 lbs. I took one home with me. I melted down a small corner, and I'm pretty darn sure it's 50/50. It melts easy, is extra shiny, and when a cooled stream is bent, it has that beautiful crackle. At $.60 a lb, I plan to scarf up the rest tomorrow. Has anyone else encountered solder like this?
