Mirabilite is a mineral that has been named for its remarkable nature. The spelling of this word is pronounced as /ˈmɪr.ə.bɪ.laɪt/ in the International Phonetic Alphabet (IPA). The first syllable "mir" is pronounced with the vowel sound /ɪ/ and the second syllable "a" is pronounced with the sound /ə/. The final syllable "bite" is pronounced with the long i sound, /aɪ/.

Mirabilite is a noun that refers to a white or a slightly yellowish mineral composed primarily of hydrated sodium sulfate. It belongs to the class of sulfates and is commonly found in saline lakes, salt flats, and other saline environments.
Chemically, mirabilite has the formula Na2SO4·10H2O, which signifies its composition. The mineral is composed of sodium ions (Na+), sulfate ions (SO42-), and water molecules (H2O).
Mirabilite is known for its characteristic needle-like or fibrous crystal structure. It often forms as a crust or a layer on the surface of salt pans and evaporation ponds. The mineral can also occur as a result of the evaporation of underground or surface waters in arid regions.
In terms of its properties, mirabilite is soluble in water and has a cooling, salty taste. It is commonly used in industry for various purposes, such as in the production of glass, detergents, and textiles. Moreover, mirabilite has been used for medicinal purposes in different cultures throughout history, specifically in bath treatments for certain skin conditions or as a laxative.
Overall, mirabilite is a naturally occurring mineral that is primarily composed of hydrated sodium sulfate. Its distinctive crystal structure and occurrence in saline environments make it an essential mineral for various industrial applications and historical medicinal practices.
The word "mirabilite" comes from Latin, specifically from the word "mirabilis", meaning "admirable" or "wonderful". It was first introduced and used in the field of mineralogy in the 18th century to refer to a specific mineral, sodium sulfate decahydrate.
