Blödite

Blödite or bloedite is a hydrated sodium magnesium sulfate mineral with the formula Na₂Mg(SO₄)₂·4H₂O. The mineral is clear to yellow in color often darkened by inclusions and forms monoclinic crystals.

Blödite was first described in 1821 for an occurrence in a salt deposit in Ischler Salzberg, Bad Ischl, Gmunden, Austria and named for German mineralogist and chemist Karl August Blöde (1773–1820).<ref name=Mindat/><ref name=Webmin/>
