This decay was deliberately produced under extreme conditions. Byne's disease can appear as a powdery white coating on a shell or other calcareous specimen.
Efflorescence is usually the result of mineral solutions in the capillary channels being drawn to the surface. If the water evaporates, the minerals remain as the so-called efflorescence. It also can be the result of chemical reaction; if badly prepared cement-based mortar is applied to maintain the stone in position, free calcium hydroxide may ...
