Potash

Potash is the common name of potassium carbonate (K2CO3), a substance that 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.

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.

The element potassium derives its English name from potash.

Caustic potash is the common name of potassium hydroxide (KOH).
