Porcelain stoneware is a compact non-porous ceramic obtained from feldspar clays, kaolins and sand, raw materials that are finely ground and mixed. It is then cooked in the oven at a temperature between 1250 and 1350 degrees. At such temperatures, a partial melting called greification takes place. After this process, a state of vitrification and impermeability is reached with absorption values lower than 0.3%. It is a product with a high resistance to mechanical stress, chemical attack, scratches and abrasion. The advanced technology with which it is produced allows it to be easily sanitized, resistant to sudden changes in temperature, fire, mold and UV rays without altering colors, characteristics and properties.
