Well, it was neat getting to see the various #s for lead composition, seeing trends in it, wondering how it shot, how each person ended up w/ that composition, etc. So the big question is, "Now that you know what is in your lead, what have you learned?"
Were you surprised to see some elements? Expecting it? Does it answer questions about how the lead casts? Does it raise more questions?
In the sample I had done 6 months ago I learned that there was a reason the lead was super runny, light weight, and sheeted when it cast... namely that it was highly alloyed in tin, antimony, and some copper. It also told me what I needed to turn it into something better.
So... What have you learned?
