Name:
First described as Selenbley by Stromeyer & Hausmann (1825). Named Clausthalie by Beudant in 1832, for the locality where it was first found ("mine de Lorenz près de Klausthal"). It was Dana who, in his first System of Mineralogy (1837), "standardised" the French name to its current mineral name.
Galena Group. Clausthalite-Galena Series.
Note: Above 300°C, there is a complete solid solution series along the join PbS-PbSe, whereas miscibility gaps exist below ∼350°C and 805°C along joins PbSe-PbTe and PbS-PbTe, respectively (Liu and Chang, 2018).

Other Information
Thermal Behaviour:
Decrepitates in the closed tube. In the open tube, gives fumes of selenium and a red sublimate. Before the blowpipe, on charcoal, gives a strong odor of selenium and partially fuses. Coats the charcoal first gray with a reddish border (selenium) and then yellow (lead oxide). When it is pure, it is entirely volatile. With soda, gives a globule of metallic lead.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
