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).
usually made from wood ashes. One of the three main minerals in fertilizer. A term used to denote potassium. Quiet Woods Winston, David Buy this Art Print at AllPosters.com
A form of potassium contained in the soil and fertilizers and utilized by plants.
Commonly used for the chemical potassium carbonate (K2C03), a component of oil emulsions.
A fertilizer containing potassium which is needed for heathy crop growth and good yields.
Term used to designate carbonate, oxide or potassium hydroxide. It is the principal ore of potassium.
potassium-rich salts derived by evaporating wood ash in iron pots and used in glassmaking
or caustic potash Noun — Common name for potassium hydroxide, the base that you can get from combining hardwood ash and water. This is used in producing soft and liquid soaps.
Broadly, potash describes any material containing potassium. More specifically, though, potash is potassium carbonate derived from wood ashes. The term potash comes from the process of extracting lye from wood ashes in iron pots.
a potassium compound often used in agriculture and industry
Prepared by evaporating the lixivium of wood ashes in iron pots
Any compound containing potassium.
Potassium carbonate. It is an alternative to soda as a source of alkali in the manufacture of glass. Potash glass is slightly more dense than soda glass; it passes from the molten to the rigid state more quickly, and it is therefore more difficult to manipulate into elaborate forms. However, it is harder and more brilliant, and lends itself to decorative techniques such as facet cutting and copper-wheel engraving.
Used to describe potassium compounds or ores.
Agricultural potassium; potassium carbonate (K2CO3) and other formulations.
crude or purified potassium carbonate, K2CO3 ( vegetable alkali, pearl ash) or crude sodium carbonate leached from the ashes of plant material; or potassium hydroxide, KOH ( lye), or even potassium oxide, K2O. [ Dalton, Rayleigh, T. Thomson et al.
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.
