Nota de aplicación

Rare halide mineral, oxy-chloride of lead, occuring as colorless, transparent striated crystals. Laurionite forms when salt water comes in contact with lead bearing slag, or as an oxidation product in lead ore deposits. The presence of laurionite in some ancient Egyptian cosmetics suggests that the mineral was purposely synthesized by the Egyptians using "wet" chemistry.
