49 results about "Glauberite" patented technology

Glauberite is a monoclinic sodium calcium sulfate mineral with the formula Na₂Ca(SO₄)₂. It was first described in 1808 for material from the El Castellar Mine, Villarrubia de Santiago, Toledo, Castile-La Mancha, Spain. It was named for the extracted Glauber's salts after the German alchemist Johann Rudolf Glauber (1604–1668).
