lead ingot codes

[buzzard pickins]

I recently aquired a number of ingots. Sellers claimed some were 20-1, or pure lead. NEED HELP, where do you find a resource to decipher codes?

INGOT #1 B613 2SN68b----#2 4SN/96PB
THANK YOU.

on #2 I believe that is a % code on it 4% tin (SN) and 96% lead (PB). The SN and PB are the table of elements abbreviations for tin and lead.

On #1 I would guess that quality control wasn't real good in the stamping department. My guess would be 2% tin and 98% lead.

Hope this helps.

Did a little research with the new info on #1 and it is 2% tin, 6% antimony, and the rest 92%, should be lead. Antimony if I remember correctly is a flowing agent, also used in solders for plumbing. No problem for the help, always glad to help a fellow member where I can.

Tin is the flowing agent also used is solder antimony is what hardens the lead.
