What is meant by shade and caliber?
Ceramic is a natural material with a natural composition which becomes resistant when fired at very high temperatures. This process, however, can cause slight differences in the shades of colour and in the actual dimensions of a tile between one batch and the next. Therefore, tiles are grouped before packaging according to their shade and their caliber. These are then indicated on the label of every pack.
