I got some lead from a neighbor in the form of some real old fishing sinkers. I have no clue as to the composition but with a fingernail test it seemed rather soft. I thought about it a minute and just said what the heck and smelted it anyway.
So here it is the next day and I test the hardness and I get 13BHN with it. Here I thought it was pure lead at first but now I'm wondering why if it felt like pure lead with my fingernail is it so hard. I smelted some sheet lead last month and that checked out at 6-8 BHN.
Anyone have any guesses here? The weights themselves were round and came in different sizes ranging from 1-2 lbs each with the typical steel eye protruding from the lead ball just like one of those real small sinkers one would find at a tackle shop.:coffee:
