I melted down about 65lbs of lead pipe last week. I was trying to compare the fresh ingots to some WWs, Babbet, etc. by using the ball bearing method to check the BNH. It worked pretty well when I checked out new lead against the WW alloy. The WW showed about 11-12 BNH. The babbit was about a 16. That all seemed good until I pulled out a fresh bunch of lead ingots. Some of them were much harder than the first few I was using. These were showing up at about 10 compared to the first ones I used. Could a couple of joints have caused that much varriation in a 10lb pot? Obviously I filled it up several times to melt the pipe.
