Abstract[edit]

Typical deterioration patterns for architectural ceramics are discussed and explained.


Decay pattern of architectural ceramics[edit]

Deterioration of brickwork

Salt-induced damage to bricks is common.

Damage to bricks can appear as follows:


Glazed architectural ceramics

The glaze on building ceramics prevents the transport of moisture and salts. Often however, the glaze is split into a fine network of cracks (craquele), allowing the moisture transport through capillary action. In the fissures of the craquele, salt contamination can be seen particularly well and often this damage leads to the spalling of the glazes.


Some examples of salt-contaminated glazed building ceramics are shown here.
