The most widely used alum is potassium alum. It was used since antiquity as a flocculant to clarify turbid liquids, as a mordant in dying, and in tanning. It is still widely used to purify piped water, in medicine, for cosmetics (in deodorant and antitranspirants), in food preparation (in baking powder and pickling), and to fire-proof paper and cloth.
