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:
Enamel fractures can vary in severity, ranging from minor cosmetic issues to more significant structural problems. [1] An enamel fracture typically doesn't cause any noticeable symptoms such as tenderness or an increase in mobility. However, if sensitivity and mobility are present, it may indicate an enamel-dentine fracture or a root fracture. [1]
Non-shrink grout being applied to tiles. Non-shrink grout is a hydraulic cement grout that, when hardened under stipulated test conditions, does not shrink, so its final volume is greater than or equal to the original installed volume. It is often used as a transfer medium between load-bearing members.
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 ...
Argon [57] [58] proposed an alternative crazing criterion based on a molecular theory for distortional plasticity, he described the process of crazing as a micromechanical problem of elastic-plastic expansion of initially stable micropores produced by a thermally activated mechanism under stress to form a craze nucleus. With his analysis of the ...

The marine and air transportation, [9] offshore structures, [10] industrial plant and facility management industries depend on maintenance, repair and overhaul (MRO) including scheduled or preventive paint maintenance programmes to maintain and restore coatings applied to steel in environments subject to attack from erosion, corrosion and environmental pollution.
Enamel is glass, not paint, so it does not fade under ultraviolet light. [28] A disadvantage of enamel is a tendency to crack or shatter when the substrate is stressed or bent, but modern enamels are relatively chip- and impact-resistant because of good thickness control and coefficients of thermal expansion well-matched to the metal.
