Potassium Alum is the white crystalline natural mineral salt (double sulfate) of Potassium Potassium Alum is specific chemical compound that is also part of a class of Alum chemical compounds. The term Alum refers to variousdouble sulfates that have the general formula of (SO4)3•24H2O plus an additional element, such as Potassium, which results in Potassium Aum: KAL(SO4)2•12H2O.

Potassium Alum has been a sought after natural mineral salt for thousands of years due to its abilities to effectively contribute to water purification, pickling, tanning, medical procedures and in cosmetics as an aftershave or deodorant. Additionally, due to its attractive Crystal appearance, Potassium Alum has become a favorite amongst mineral collectors. It is commonly used in water purification, leather tanning, dyeing, fireproof textiles, and baking powder.

Potassium Alum
(Alumbre) is a naturally occurringsulfate mineral which typically occurs as encrustations on rocks in areas of weathering and oxidation of sulfide minerals and potassium-bearing minerals.  The crystal Alum mineral is commercially extracted in select quarries throughout the world. It has been reported in Tennessee, and Arizona in the United States, and also, in South America, in the Andies between Bolivia, Chile and Argentina.

Potassium Alum crystallizes in regular octahedra with flattened corners, and is very soluble in water. The solution reddens litmus and is an astringent. When heated to nearly a red heat it gives a porous, friable mass which is known as "Burnt Alum".  It fuses at 92 °C in its own water of crystallization. "Neutral Alum" is obtained by the addition of as much Sodium Carbonate to a solution of Alum as will begin to cause the separation of Alumina.
