What is Porcelain Stoneware? Understanding Premium Ceramic Tiles

The porcelain stoneware is composed by a mixture of raw materials whose composition does not differ from that of vitreous china (used in manufacturing sanitaryware and crockery).

Therefore, it is a completely impervious material and with high mechanical features. The term porcelain, underlining stoneware’s refined elegance, derives from the use of kaolin, a kind of white clay used also in the production of bone china.

Clays and valuable feldspars, undergoing a firing process at extremely high temperatures, turn into stoneware tiles with the following features: chemical- and frost-resistance, impact strength and scratch hardness.
