Kieserite

 

(after the German scientist D. G. Kieser, 1779–1856), a mineral of the sulfate class, chemical composition, Mg[SO4] · H2O, containing 29.0 percent MgO.

Kieserite crystallizes in the monoclinic system. Crystals are rare; compact fine-grained aggregates are more usual. Kieserite is milky white, sometimes yellowish, in color. Its hardness is 3.5 on the mineralogical scale; its density, 2,570 kg per cu m. The mineral is brittle and readily soluble in water. The taste is bitter. Kieserite is a typical mineral in fossil salt deposits (more rarely, in modern salt-lake sediments), where it is formed chiefly as a result of the metamorphism and dehydration of the mineral epsomite. Kieserite is used, along with other magnesium sulfates, in the chemical, textile, and paper industries and in medicine.
