About GlaucodotHide

Formula:

(Co_0.50Fe_0.50)AsS

Colour:

Grayish tin-white to reddish silver-white

Lustre:

Metallic

Hardness:

Specific Gravity:

6.055

Crystal System:

Orthorhombic

Member of:

Arsenopyrite Group

Name:

Named in 1849 by August Breithaupt and Karl Friedrich Plattner from the Greek γλαυκός for "sky-blue" and δίδω "to give", because of its use in making blue smalt glass (blue color caused by Co²⁺).

Type Locality:

ⓘ Huasco, Huasco Province, Atacama, Chile

See also the chemically similar Cobaltite (ideally CoAsS) and Alloclasite (richer in Co than glaucodot). Compare 'UM1966-01-As:CoNiS'.
