When the lead plant back east got closed down, a neighbor gave me about 60 lbs of wheel weights, I melted them down and cast ingots of them. Then I had a chance to get some Lino Type (about 40 lbs) and did the same thing with them, melted them down and cast them into ingots. Now they have been under my work bench and I can't tell the difference in the bars of ingots. Is there any way to tell the difference between the pure lead ingots and the lino type ingots? Does one weigh more than the other? Do I have to do a hardness test, like a brindle test or something like that? Is there a simple way to tell the difference between the two? Thanks for the answers.
