Named in 1813 from the Greek for "fire" and "form" because after being melted into a globule a sample will begin to take on a crystalline shape during cooling.
A secondary lead mineral found in the oxidized zones of lead deposits (Lead Chlorophosphate). Typically found as green to yellow barrel-shaped hexagonal prisms, in clusters or as druses on matrix. The individual crystals are often modified or etched, giving a hopper-like appearance. This lead chloride phosphate forms a complete series with Mimetite , or Vandinite and many specimens are partially developed formations between the two. Color is typically green, but can also be yellow, orange and brown. Notable Occurrences include Idaho and Pennsylvania in the USA, Mexico, Germany, England and Australia.

Old Stock Pyromorphite from the Wheatley Mine
This is an "Old Stock" specimen from the 1950's of Pyromorphite from the Wheatley Mine in Phoenixville, PA.
It comes with the original Mineral ID tag from the Willis' Earth Treasures-Minerals shop in Stewartsville, NJ where it was originally purchased in the 1950's by the collector we got this specimen from.
The location commonly called the "Wheatley Mine" in Phoenixville, Chester County, PA is actually a series of classic lead, zinc mines located on one ore body. The mines consisted of the Wheatley Mine, the Phoenix Mine, and the Brookdale Mine, all owned and operated by Charles Wheatley, and the Montgomery Mine, the Chester County Mine, the Roberts Mine and a few smaller claims. The Wheatley Mine, opened in 1851, is by far the most outstanding source of beautiful and rare lead, zinc, copper and vanadium minerals in the eastern United States. Pyromorphite from the Wheatley Mines is among the finest in the world!
