Alum is a chemical (aluminium potassium sulphate), It tends to be whitish powder with several uses, including: * As an astringent * As an antibacterial * As a food preservative * As a 'Styptic pencil' to quickly heal shaving cuts * To stem the flow of minor blood loss and cuts * Soaked into materials to make them flame retardant There are other uses, but these are some of the more common ones...

But alums are also called double sulfates of K, NH4 and Al, Cr(III).

How alum formed?
Alum is a chemical compound of two distinct salts, namely: Sulphate of alumina and sulphate of potassa, or sulphate of alumina and sulphate of ammonia. The last salt is present only in a few varieties, and other specimens contain a soda salt with the salt of alumina, and still others substitute an iron salt for alumina. The following symbols represent the more familiar specimens:Roman or Rock Alum. KO.SO3+Al2O3+24HO. Ammonia Alum. NH~O.SO3+AI2O3+24HO. Iron Alum. KO. SO3+Fe203+24HO. The proportion of water is thus seen to remain uniform through them all, while the characterizing salt is a tersulphate of a sesquioxide.Rock Alum is the one used in medicine. It is found in a nearly pure state in the volcanic region of Italy, and is purified by solution and subsequent crystallization. The almun ores are certain slaty earths, from which the alum is manufactured by calcination, exposure to the air for three months, and subsequent lixiviation and crystalyzation. Burnt Alum is merely alum deprived of its water by heat. It is powdered and sprinkled upon fungous flesh, acting as a very mild escharotic.
Would Epsom salt alum be the first or last to dissolve in a metamorphic process?

What happens to aluminum during electrolysis?
