Named in 1895 by Stens Anders Hjalmar Sjögren in honour of Anders Celsius [November 27, 1701 Uppsala, Sweden - April 25, 1744 Uppsala, Sweden], Swedish astronomer, physicist, and naturalist.

celsian, an uncommon feldspar mineral, barium aluminosilicate (BaAl 2 Si 2 O 8), that occurs as hard, light-coloured, glassy masses and crystals in association with manganese deposits in contact zones, as at Jakobsberg, Swed.; Tochigi prefecture, Japan; Rhiw, Wales; near the Omuramba Otjosondjou (dry riverbed), Namibia; and near Incline, Calif ...

Celsian is a very rare barium-rich member of the feldspar group. This mineral is named after Anders Celsius (1701-1744), a famous Swedish astronomer and scientist who proposed the Celsius temperature scale.

Rectangular crystal in the upper right corner is titantaramellite (ti) and isometric crystals included in sanbornite are celsian (ce). Location: Trumbull Peak, near Incline, Mariposa Co., California, USA.

Celsian is a mineral with formula of BaAl 2 Si 2 O 8 or Ba(Al 2 Si 2 O 8). The IMA symbol is Cls.

Celsian is an uncommon feldspar mineral, which was first discovered in 1895 in Imfeld Binnental, Switzerland. The mineral was named after the Swedish astronomer and natural scientist, A.Celsius. The following are the key properties of Celsian: As short prismatic to acicular crystals, with large prism faces, to 2cm; commonly massive.
