Use
Aluminium potassium sulfate dodecahydrate is a white crystal that is soluble in water. It is made by roasting alunite in a furnace and then harvesting the product by crystallization. Aluminium potassium sulfate dodecahydrate was used to harden gelatin emulsions by introduction, by bathing the exposed plates prior to development, or by use in the fixing bath. Mixed with citric or other acids, it was also used as a clearing bath to remove developer stains in negatives.
