//** Metallic potassium was first isolated by Sir Humphry Davy in 1807 through the electrolysis of molten caustic potash (KOH). Potassium can be obtained from the minerals sylvite (KCl), carnallite, langbeinite, and polyhalite. These minerals are often found in ancient lake and sea beds. Caustic potash, another important source of potassium, is primarily mined in Germany, New Mexico, California and Utah. **//
 * // History of Pure Potassium //**

//** Potassium chloride is the most common potassium compound. It is used in fertilizers, as a salt substitute and to produce other chemicals. Potassium hydroxide is used to make soaps, detergents, and drain cleaners. Potassium carbonate, also known as pearl ash, is used to make some types of glass and soaps and is obtained commercially as a byproduct of the production of ammonia. Potassium superoxide is used in respiratory equipment. Potassium nitrate, also known as saltpeter of nitre, is used in fertilizers, match heads and pyrotechnics. **//
