I was given about 800 lbs of used babbitt and it is now in nice 1 lb. ingots. However, the giver, did not know whether it was lead based or tin based. I suspect it is lead but they are HARD. I can break them, and they literally ring when knocked together. I have been using it sparingly in my normal COWW melt when casting because if I put too much in, the bullets start to stick in the mold. I'm guessing 8 ounces or so in a 20 lb melt.
Is there some place that I could send an ingot for analysis? I sure would like to know just what I have plus be able to sell some, because I for sure will not be able to use it all in the small amounts that I am currently using.
