How do you identify alum stone and where is it from?
Alum stone is a potassium-rich mineral extracted from a rock. It is white in color and resembles a crystal. It can be purchased in small blocks. Alum mines are mostly found in South America and Asia, particularly in Egypt, historically. The Romans mined it in from desserts west of the Nile River and were believed to have used alum in a number of ways. It’s prime use back then, though, was solely to purify drinking water. Bakers in 18th century England used alum in ample quantity to make their loaves of bread appear whiter and thus sell faster.
