. . . . "Potash /\u02C8p\u0252t\u00E6\u0283/ 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. Today, 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 1808."@en . . . . . . . "Wikipedia Article About Potash on Wikipedia Potash (or carbonate of potash) is an impure form of Potassium carbonate (K2CO3) mixed with other potassium salts. Potash has been used since antiquity in the manufacture of glass and soap, and as a fertilizer. The name comes from the English words pot and ash, referring to its discovery in the water-soluble fraction of wood ash. It is today principally produced by mining suitable deposits which are found throughout the world."@en . . "Potash"@en .

It is today principally produced by mining suitable deposits which are found throughout the world. The term has become somewhat ambiguous due to the substitution in fertilizers of cheaper potassium salts such as potassium chloride (KCl) or potassium oxide (K2O), to which the same common name is now sometimes also applied. In addition, potassium hydroxide (KOH) is commonly called caustic potash, an additional source of confusion."@en . "Potash"@en . .
