Potash \Pot"ash`\, n. [Pot + ash.] (Chem.)
The hydroxide of potassium hydrate, a hard white brittle substance, KOH, having strong caustic and alkaline properties; -- hence called also caustic potash.
The impure potassium carbonate obtained by leaching wood ashes, either as a strong solution (lye), or as a white crystalline (pearlash).
Douglas Harper's Etymology Dictionary
1751, earlier -pot-ashes (1640s), a loan-translation of older Dutch potaschen, literally "pot ashes" (16c.); so called because it was originally obtained by soaking wood ashes in water and evaporating the mixture in an iron pot. Compare German Pottasche, Danish potaske, Swedish pottaska, all also from Dutch. See also potassium. French potasse (1570s), Italian potassa are Germanic loan-words. The original plural was pot-ashes.

Wikipedia
Potash is any of various mined and manufactured salts that contain potassium in water-soluble form. The name derives from pot ash, which refers to plant ashes soaked in water in a pot, the primary means of manufacturing the product before the industrial era. The word potassium is derived from potash.
Potash is produced worldwide at amounts exceeding 30 million tonnes per year, mostly for use in fertilizers. Various types of fertilizer-potash thus constitute the single largest global industrial use of the element potassium. Potassium was first derived by electrolysis of caustic potash (aka potassium hydroxide), in 1807.
Potash may refer to:
- Potash, potassium carbonate
- Potash, Suffolk, United Kingdom
- Potash City, Jordan
- Potash Corporation of Saskatchewan
- Potashes (gang), a 19th-century New York City street gang
- Dan Potash, a television reporter for FSN Pittsburgh
