I'm not even sure that is the proper term for a metal analyzer. Anyway, I found a giant hunk of lead. I would guess that it's near pure lead. But before I commit any funds towards buying any I'd like to know how hard it is. One of the Employee's there says he will shoot it with the analyzer on Monday, but I have no idea how to interpret the data to gauge how hard it may be. I believe soft lead would be something like 95% Pb+5% Sb (lead and antimony) with traces of Sn (tin), As (Arsenic), if I read that other post correctly. But is that what a XRF gun will tell you or do I got to have a degree in Metallurgy to know how hard that lead may be ?
