The New International Encyclopædia/Vanadinite

VANADINITE. A mineral lead chloride and vanadate crystallized in the hexagonal system. It has a resinous lustre, and in color varies from yellow to red and brown. It usually occurs as prismatic crystals with smooth faces and sharp edges, also sometimes in rounded forms and globular incrustations, and is found in the Urals, Sweden, Argentina, South Africa, and Mexico, and in the United States with wulfenite and pyromorphite at various localities in New York, Arizona, and New Mexico. This mineral finds some use as a source of vanadium salts, which are used as a pigment for porcelain, and in the manufacture of ink.
