Ceramic tiles fired at 1120șC to 1200șC, in which retraction occurs. In addition to tonality and defect classification, the non rectified ceramic tiles are separated into sizes. Separation occurs according to product format and the tolerance allowed by standards. CEUSA classifies its non rectified ceramic tiles with Codes: P or L (small), M or N (medium) and G or T (large).
In addition to the reference and tonality code, it is necessary to check on the identity label on the packaging, if the size codes are identical, particularly if laying a checkered pattern. |
