If I want my mix I take 18 lbs of supposedly 99.9% pure as advertised and add one roll of 95/5 no lead solder that is 95% tin 5% antimony. The solder is about as close to the specs as you can get. The batch I mix weighs around 70 lbs

:lol: The eyes work fine! I just assumed that the "Batch" contained 52lbs of 95% - 5%. to make 70 lbs. :roll: :lol: :lol:

Lead alloys with antimony will continue to harden over 90 days.

However lead alloys with tin will soften over 90 days.
