Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand. [1] [2] Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix ...
The history of ceramic repair is vast and ranges from different methods and methodologies. For example, in 16th century China, people would repair broken ceramics by using pieces from other objects to disguise the patch. A sixteenth-century manuscript describes the process of patching broken ceramics:
Lacquerware is a longstanding tradition in Japan [6] [7] and, at some point, kintsugi may have been combined with maki-e as a replacement for other ceramic repair techniques. . While the process is associated with Japanese craftsmen, the technique was also applied to ceramic pieces of other origins including China, Vietnam, and Kor
Clean non-porous surfaces, like bathroom tile and ceramic floors, with mold-killing products, like bleach. Clean porous surfaces, like wood, with bleach alternatives such as a hydrogen peroxide ...
Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. The maximum temperature jump, , sustainable by a material can be defined for strength-controlled models by: [4] [3] = where is the failure stress (which can be yield or fracture stress), is the coefficient of thermal expansion, is the Young's modulus, and is a constant ...
Vitreous china is an enamel coating that is applied to ceramics, particularly porcelain, after they have been fired, though the name can also refer to the finished piece as a whole. The coating makes the porcelain tougher, denser, and shinier, and it is a common choice for items such as toilets and sink basins. [1] [2] [3]

Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating.
