General name for any potassium-containing
mineral, most often applied to potassium
carbonate (K2CO3). Potash, originally made by
roasting plants to ashes in earthenware pots,
is commercially produced from the mineral
sylvite (potassium chloride, KCl) and is used
mainly in making artificial fertilizers,
glass, and soap. The potassium content of
soils and fertilizers is also commonly
expressed as potash, although usually meaning
potassium oxide (K2O).
