TILE TECHNOLOGY
Red body and white body Ceramic tiles are made with finest quality clays and with chamotte (a ceramic raw material with high percentage of silica). These raw materials are submitted to dry grinding and suitably mixed and wet and then pressed with hydraulic presses. Quick-cycle support firing is obtained via roller kilns reaching temperatures of approximately 1100 °C.
After biscuit glazing, the vitrified product is sintered in a single-layer roller kiln at approximately 1030 °C.
The resulting wall tiles have an average bending strength that is higher than 15/ mrre in accordance with the UNI EN ISO 10545-4 standard and a water absorption level that is higher than 10 %; they belong to the Blll (GL) group according to the UNI EN 14411 standard. This class of products shows virtually no shrinkage during firing; therefore such dimensional consistency results in extremely easy laying.
