The ancient spring he found was still flowing and the water contained large amounts of calcium sulfate which functions as a strong laxative.
Other inorganic sulfate salts such as sodium sulfate and calcium sulfate may also be used in the same way.
A cool cabinet with a desiccant, such as calcium sulfate, can also serve as a good storage area.
These precipitation processes tend to concentrate radioactive elements in the calcium sulfate product.
These are often made not from chalk rock but from calcium sulfate in its dihydrate form, gypsum.
