Efflorescence

When white crystals appear on the surface of masonry, or plaster, these are referred to as 'efflorescence'. The phenomenon is due to the movement of mineral salts from the body of the stone to the surface, as a result of movement of moisture. It may be an indication of water penetration or condensation, and thus a need for repairs. Related Words: M...

Efflorescence

In mineralology, efflorescence is the property which certain crystals possess of losing their clear transparent character and producing a light powder on the surface, eg washing-soda. Efflorescence is also the name given to the fine crystalline deposits (magnesium and sodium sulphates) which appear on walls, etc.
