Refractory modules are provided by multiple preformed refractory blocks bonded to one another by a bonding agent to form an integral self-supporting structure having a tooth and channel arrangement for interlocking assembly with a similar adjacently positioned refractory module.

Refractory components (e.g. crown or rider arches associated with a refractory structure such as coke ovens, glass furnaces, regenerators and the like) are provided by multiple refractory members bonded to one another by a bonding agent to form an integral self-supporting structure.
