Since there has been a sudden uptick in people following my nonsense, here is my favorite #mineral specimen.

#Pyromorphite from the Wheatley Mines in #Pennsylvania circa ~1870s. Before being shut down, the Phoenixville District sourced much of the lead used in bullets for the American Civil War. I like the thought of Pennsylvania rocks breaking Confederate skulls.

@deinonychus By that you mean Union bullets, no?
@SonofaGeorge Absolutely.
@deinonychus I've been to Gettysburg and have one of each - a Union bullet and a Confederate bullet.
