Efflorescence, Soluble Salt Migration
A term describing the whitish scum left on the surface of a fired clay body (most often red earthenware). Many clays contain soluble sulphates that are left on the surface after they have been brought there by water and it has subsequently evaporated. This can happen during initial drying after forming (during manufacture) or it can happen later after the clay is fired and subjected to repeated wet-dry cycles in use (e.g. brick). This problem can be dealt with used additions of barium carbonate. Out Bound Links
