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...

What are the characteristics of alum?
Alum is a double sulfate salt with astringent properties. It is commonly used as a deodorant, aftershave, and for pickling. Alum is also known for its ability to treat canker sores and minor skin irritations.
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.

Is epsom salt the same as alum?
No, Epsom salt (magnesium sulfate) and alum (potassium aluminum sulfate) are different compounds. Epsom salt is commonly used for soaking and muscle relaxation, while alum is often used as a deodorant or in pickling.

Salt crystals generally grow faster than alum crystals because salt is more soluble in water and forms crystals more quickly. Alum crystals tend to grow slower due to their lower solubility in water.
Where can you get alum salt?
spice section in the food store
Which one has a stronger bond salt sugar or alum?
Alum typically has a stronger bond than salt or sugar due to its ionic nature. Alum forms bonds through electrostatic attraction between positive and negative ions, resulting in a stronger bond compared to the bonds formed in salt or sugar molecules.
