In chemistry, Efflorescence is the loss of water (or solvent) of crystallization from a hydrated or solvated salts to the atmosphere on exposure to sir.

eg: Gypsum (CaSO₄.2H₂O) is a hydrated solid that in a sufficiently dry environment,will give up it's water to the gas phase and form anhydrite (CaSO₄).
