Moisture, wetting and/or damp packing may be responsible for hair- line cracks in the glaze. "Crazing," a series of minute cracks in the glaze which occurs in manufacture, should not be treated as transit damage. A crack sometimes is due to a manufacturing defect caused during the firing or drying process and should be readily distinguishable by the gap in the enameling. Vitreous or enameled surfaces are liable to breakage and chipping, much of which can be avoided by the liberal use of felt or corrugated cardboard uniformly distributed over the surfaces and where in contact with case or crate.
Tinted earthenware is particularly subject to water damage by reason of the decorative portion sometimes being easily rubbed off. See also ENANELWARE.
