Glauberite is a mineral with a unique spelling, pronounced as /ˈɡlaʊbəraɪt/. It is named after Johann Rudolf Glauber, a German-Dutch chemist who first discovered the mineral. The spelling can be broken down into individual IPA phonetic symbols, including a glottal stop /ʔ/ at the end of the first syllable, followed by the diphthong vowel /aʊ/ in the second syllable, and ending with the consonant cluster /br/. Despite its unusual spelling, Glauberite remains an important mineral with distinctive properties, including its use in the production of glass and ceramics.
Glauberite is a mineral that belongs to the sulfate mineral group. It is composed of calcium sulfate and sodium sulfate in equal parts, with the chemical formula Na2Ca(SO4)2. It typically forms as evaporite deposits in arid or semi-arid environments where saline waters evaporate, leaving behind mineral precipitates. Glauberite is commonly found in association with other evaporite minerals such as halite, gypsum, and anhydrite.
The physical appearance of glauberite can vary, but it is usually colorless or has a pale yellow to brownish hue. It crystallizes in the orthorhombic crystal system, often forming elongated prismatic or tabular crystals. It has a relatively low hardness of 2.5 to 3.5 on the Mohs scale, making it relatively soft and easily scratched.
Glauberite is named after the German-Dutch chemist and apothecary, Johann Rudolf Glauber, who made significant contributions to the fields of chemistry and medicine. It has various industrial applications, including its use as a source of sodium sulfate in the production of detergents, glass, and paper. Glauberite is also used as a fertilizer and in the manufacturing of certain chemicals.
Due to its relatively common occurrence, glauberite is found in several locations around the world, including Germany, Romania, Russia, the United States, Mexico, and China. Its formation is closely associated with evaporite environments, where evaporation and concentration of saline waters create the necessary conditions for glauberite to precipitate and form solid deposits.
A rare crystallised salt.

The word "Glauberite" is derived from the name of the German-Dutch chemist and apothecary Johann Rudolf Glauber (1604-1670). Glauber made significant contributions to the field of chemistry in the 17th century, particularly in the study of salts. Glauberite, a mineral composed of sodium calcium sulfate, was named in his honor in recognition of his pioneering work in the field.
