A few days back I posted a "What's Going On" entry where I had you guess what this particular specimen is. What you may notice is that the Sholesonian Identification on this piece is a bit different than others in the Geology collection. You see I didn't quite have a place for this piece to go. If you haven't noticed yet this gray sheet is a slice of some malleable lead (Pb, which stands for the Latin name plumblum). And this specimen doesn't really belong anywhere in the Collections I've set up. It's a man-made sheet so it doesn't quite belong in Geology but seeing as it once came from the Earth I'm going to place it there but create a subsection of pieces of a more Chemical nature.
