Porcelain stoneware is a high-quality tile and the result of a sophisticated production process that begins with the selection of excellent raw materials such as clays, feldspars, quartz and other elements. These components are then finely ground, mixed and fired at temperatures of up to 1235 °C, transforming them into an extremely compact and resistant material.
The origin of the term reflects quality and production process, with ‘stoneware’ indicating the stone-like density resulting from the greification of the sands during firing, and ‘porcelain’ referring to the pure, white clays used.
This composition gives porcelain stoneware unique properties of durability and strength, making it ideal for a wide range of applications.
Technical characteristics of porcelain stoneware
LOW POROSITY
Porcelain stoneware has an extremely low porosity, due to its low water absorption coefficient of less than 0.5%.
CHROMATICALLY STABLE
Colours are absolutely stable and are not altered by exposure to sunlight, atmospheric agents or smog.
NON-REACTIVE TO FIRE
This material does not burn or produce toxic-harmful gases or fumes in the event of fire or exposure to flame.
ABRASION RESISTANT
Its resistance to abrasion and wear is superior to any that of any natural material. Given its surface resistance due to baking and pressing, this material resists impact and is not affected by the movement of objects, even heavy ones, over its surface.
RESISTANT TO STRESS
The high tensile strength of the material enables it to withstand the bending generated by even particularly heavy loads. If the specific laying instructions are adhered to, it can be used to paved driveways, which can withstand even the weight of cars.
ACID-PROOF
Porcelain stoneware has the ability to withstand contact with household chemicals (stains, acids, bases) at room temperature without altering its appearance.
RESISTANT TO FROST AND THERMAL SHOCK
Porcelain stoneware is resistant to frost and, when exposed to water at temperatures below 0 °C, is not damaged by the stresses associated with the increase in volume of water due to freezing.
HYGIENIC
Its non-porous vitrified surface hinders the proliferation of fungi and bacteria.
