So I as I posted here a while back, I finally got my COWW blended like I wanted.
Sent a sample off to be tested and got the results today.
This COWW was obtained from about 1997 to 2010.
95.676% Pb
3.217% Sb
0.553% Sn
0.499% Fe
Rest is traces too small to measure.
About 2009 I got about 600 pounds of lead from a plumber in Denver.
Stuff was a lot harder than I thought it should be per my Cabin Tree tester.
Looking back on it I knew I had screwed up by melting it all down without thinking to keep the joints separate.
Sometimes I can be a real dumb a$$.
Anyways, I sent a sample of that stuff as well.
90.898% Pb
1.539% Sb
4.256% Sn
3.113% Fe
I wasn't surprised by the amount of tin but I am surprised there is over 1.5% antimony in it.
And over 3% Iron?
I wonder how that got in there.
At least now I know why this "soft" lead is so damn hard.
