Porcelain grès: History and curiosity

Porcelain grès: History and curiosity

Before reconstructing the history and characteristics of this material now widespread and highly used in the context of today's buildings, Let's start by giving a definition of grès.

Grys is a hard pasta ceramic material, obtained for cooking up to incipient glass vitrification. Has a compact pasta, dura, sound and waterproof. Very often it has a waterproof showcase coverage.

The origin of the word grès seems to derive from ancient French artifacts so called and which used the same type of clay, which takes the name of silicious gres.

The word porcelain instead derives from the white color of the white clays used to create this material. In Italy for production, materials coming mainly by Sardinian quarries and worked in the city of Guspini, in the province of Cagliari. Hence the denomination at km0 of the product.

History

Since the 1950s they took the name of Grès The non -glazed tiles with very small porosity, Create with red clays, ferruginose, non carbonate and glassing in cooking.

The final product was obviously red. The raw material was grinding dry in impact mills or hammers and cooked in tunnels with cycles of 70 hours at an average temperature of Ben 1.000 Degrees centigrade.

However the product was not the best. It had significant limits of a purely technological nature. Among these, the still rudimentary instrumentation available to ovens that prevented optimal adjustment of the cooking curve. Problems in the pressure phase of the press that did not allow to obtain the desired density level for the tiles.
Still insufficient controls of the grinding parameters, therefore granules of various sizes.

However, the result had good resistance characteristics, For example, acid and frost, but it was difficult to extract, check and was not waterproof, presenting a remarkable porosity.

This product was mainly used in public buildings as schools, hospitals, laboratories. The low costs and its resistance were preferable to prefer it.

The Porcellatoto Give

The turning point takes place around the 80s, When in Sardinia, Especially in the Sassuolo area, The construction of building theme comes to pack the best version, Until then, product.

This material proves suitable for both interiors and outdoors and is characterized by his enormous versatility. For the outsiders he manages to hold well to the wear and tear of the weather, even if for obvious reasons, tends to last less than the material used for interiors.
About duration, Grys has an almost unlimited longevity.

It is extremely Simple to clean, Using any type of detergents and disinfectants. It is also stain, does not hold up halos.

Does not require maintenance, It does not therefore require treatments for the care and polishing of wooden or marble floors.

Porcelain grès is a fireproof material and resists fire, therefore also to cigarette falls, matches, hot objects etc.. In case of incended, so, will resist the fire and will not emit toxic fumes.

One of the most important characteristics is its sustainability. The materials used to create the grès are 100% natural and recyclable. In particular, the materials are: sand, clay, minerals and feldspati. e, they do not contain plastics, are resistant to chemical agents, waterproof, hypoallergenic and recyclable.

Its use is usually designed for floors, But it can also be used for vertical surfaces.
