Anhydrite
Anhydrite got its name in allusion to Gypsum - Gypsum is calcium sulfate containing
crystal water, and Anhydrite is calcium sulfate without crystal water. Anhydrite is
'anhydrous' calcium sulfate. It is often a rock-forming mineral.
Specimen Handling
Anhydrite is for all practical purposes stable in a normal household environment. It is
not harmed by light, changes in temperature in the normal comfort range, or known to
decompose. Anhydrite specimens can be brittle and should be handled with care like any
other mineral specimen. Anhydrite is not appreciably soluble in water.
