Porcelain tiles | Grès porcelain stoneware tile
Grès Porcelain stoneware is a ceramic with a compact, hard, coloured and nonporous body. The word "grès" means that the ceramic body of the tile is extremely vitrified, that is to say compact, hence the exceptional great result is a lean clay body, little refractory, fired in a kiln (at C°) until it reaches a nonporous vitrifiion and a complete waterproofing.
