lead pipe

how pure is it? picked up 70+ lbs. stuff i got is very soft. the soldered joints are harder. also got a cylinder with 31 stamped on it. about 18 inches x 2 inches. cut easily with a knife.

lead pipe is generally as pure as it gets. the solder joints will be a bit harder with tin and antimony so if your after only pure, keep them separate from the melt.

From what I have read, about 98 % pure. But, no guarantees.

As pure as can be easily obtained

When I processed my lead, I cut the soldered joints out (with an axe on a stump), and kept the high tin content soldered joints separate from the pure lead mix.
I did it this way so that I could use the high tin lead to add to alloys that weren't filling out the mold properly.
I stamped every ingot with a stamp, from Princess Auto, so that if I accidentally got the ingots mixed up, I could still separate the different ingots.
Tin is a few dollars per pound, and lead is less than 1$/ lb.

This is my plan, when the weather warms. all my ingots are number stamped that correspond to what it is. makes sense to me.
