Pyromorphite is a lead phosphate chloride. Hausmann (1813) named the mineral by combining Greek roots pyro, fire, and morphe, form. In the nineteenth century, routine chemical analysis involved blowpipe methods which melt and burn samples to observe spectral colors. Pyromorphite recrystallizes readily on cooling from a melt, hence the mineral name.
This specimen consists of tan to orange botryoidal pyromorphite. Pyromorphite forms a ridge of spheroidal aggregates to 1.3 cm on a rock fragment. This locality is especially famous for its orange and yellow pyromorphite. Formerly in the Harold Slavik collection.
