Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. Crystals are common, and have the form of a hexagonal prism terminated by thebasal planes, sometimes combined with narrow faces of a hexagonal pyramid. Crystals with a barrel-like curvature are not uncommon. Globular and reniform masses are also found. It is part of a series with two other minerals: mimetite(Pb5(AsO4)3Cl) and vanadinite (Pb5(VO4)3Cl), the resemblance in external characters is so close that, as a rule, it is only possible to distinguish between them by chemical tests.
They were formerly confused under the names green lead ore and brown lead ore (German: Grünbleierz and Braunbleierz) it was named pyromorphite by J. F. L. Hausmann in 1813. The name is derived from the Greek for pyr (fire) and morfe (form) due to its crystallization behavior after being melted.
COLLECTORS’ INFORMATION: Pyromorphite is collected for its unusual chemistry, pleasing lime-green color, and hexagonal crystal shapes that often have distinctive, cavernous or pitted terminations.

Perché gli utenti superano se stessi?
Quando viene effettuata un'offerta, questo è l'importo massimo che un utente è disposto a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto di quegli utenti, aumentando in modo incrementale l'offerta per mantenere la loro posizione di miglior offerente, fino al massimo specificato.
Quando è presente un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente facendo offerte per l'utente in base alla sua offerta massima. Potrebbe sembrare che gli utenti stiano superando l'offerta, ma è semplicemente il risultato dell'aggiornamento dell'offerta da parte del sistema in modo da riflettere il limite massimo degli utenti.
