The production of potassium alum from alunite is archaeologically attested on the island Lesbos. A detailed description of a substance called alumen occurs in Pliny the Elder 's Natural History.
By comparing Pliny's description with the account of stupteria given by Dioscorides it is obvious the two are identical. Pliny informs us that a form of alumen was found naturally in the earth, and calls it salsugoterrae.
Pliny wrote that different substances were distinguished by the name of alumenbut they were all characterised by a certain degree of astringencyand were all employed in dyeing and medicine. This property seems to characterize a solution of iron sulfate in water; a solution of ordinary potassium alum would possess no such property.
Contamination with iron sulfate was greatly disliked as this darkened and dulled dye colours. In some places the iron sulfate may have been lacking, so the salt would be white and would be suitable, according to Pliny, for dyeing bright colors.
Pliny describes several other types of alumen but it is not clear as to what these minerals are. The alumen of the ancients, then, was not always potassium alum, not even an alkali aluminum sulfate. Alum and green vitriol iron sulfate both have sweetish and astringent taste, and they had overlapping uses.
Therefore, through the Middle Agesalchemists and other writers do not seem to have discriminated the two salts accurately from each other. In the writings of the alchemists we find the words misysoryand chalcanthum applied to either compound; and the name atramentum sutoriumwhich one might expect to belong exclusively to green vitriol, applied indifferently to both.

Some alums occur as minerals, the most important being alunite. The most important alums — potassium, sodium, and ammonium — are produced industrially. Typical recipes involve combining aluminium sulfate and the sulfate monovalent cation.
