It is easy to receive it from alkali at lixiviation ashes water from cereals or seaweed as potassium most of all in soluble part of the vegetable remains (white "ashes" from fire — generally potash). The principle of production was is as follows: in the clay burned vessel with small opening at the bottom, filled ashes and slightly stamped. Then it was filled in with certain amount of water. The water which has passed through vessel is carefully collected and fill in with it the following party. And so until liquid did not get siropoobrazny consistence. After excess liquid evaporate in metal ware and receive potash. As the by - product turns out when processing nephelines. Today potassium carbonate turns out by potassium chloride electrolysis therefore potassium hydroxide which, reacting with carbon dioxide gas, forms water and potassium carbonate is formed.
