General questions

All you need to know about ceramic tiles.

Compared to other floor and wall coverings, ceramic tiles have superior performances. In particular, ceramic tiles have better:

• abrasion and wear resistance;
• stain and chemical attack resistance;
• flame resistance;
• hygiene. Ceramic tile surfaces are easy to clean.

Porcelain stoneware, available in various surface finishes, is a mix of powders and non-metallic grains of different sizes and colours (raw materials), similar to that used for the manufacturing of sanitary-ware and crockery.  It is a "vitreous" material, completely inabsorbent with excellent technical features, guaranteeing wear resistance of the surface over time.

The complex firing process at high temperatures, transforms the precious raw materials into porcelain stoneware tiles that are resistant to frost, chemical attack, have a high mechanical resistance, are hygienic and are characteristics thanks to their refined appeal.

Full-body coloured porcelain stoneware maintains, in the body of the tile, the same material and colour configuration of the surface. The firing process of the product is designed to achieve a vitrification state following which the tile is able to possess a water absorption level lower than 0.5\% (frost-proof).
Thanks to their compactness and homogeneous surface, these products can also be used in high traffic areas.

Glazed porcelain stoneware is the result of the firing of the ceramic product that achieves a suitable vitrification state with a water absorption level lower than 0.5\% (frost-proof).
The tile mix is a neutral colour composition made from precious materials. The subsequent application of a top layer of glaze is added in order to obtain refined motion effect and graphic variety on the surface.  Glazed porcelain stoneware floors are suitable for indoor areas thanks to their stain and chemical attack resistance, making the surface easy to clean and to maintain.

The ceramic tile body consists of a mixture of top quality raw materials, which give them their characteristic white colour. This allows the brilliance and the transparency of the colours applied on the surface to come through, obtaining chromatic homogeneity and a soft tile to the touch. White-body monoporous tiles are suitable to clad walls, combining their decorative appeal with functional hygiene, hence why the subsequent graphic applications enhance their aesthetic look.

There are four main types of finishes of ceramic tile surfaces:

  • natural: the most widely used finish. The tile does not undergo any application after firing. It can be: smooth/matt, suitable for any space in particular for bathroom and kitchen cladding; textured, suitable for outdoor use as it is anti-slip.
  • semi-polished, semi-glossy or honed: a special finishing exalting the aesthetic appeal of the tile, making it smooth and increasing its shine.
  • polished or glossy: obtained via the passage of an abrasive toll that initially rubs the surface then makes it completely glossy (mirror-like effect).
  • scratch or bush-hammered: rough surface obtained using tools such as chisel, cap etc. Suitable for outdoor areas such as terraces, porches and courtyards.

Before proceeding with the purchase of any amount of ceramic tiles (e.g. to cover a bathroom or a kitchen and a living room), it is necessary to know the area of the surface to be tiled, and establish the tiling technique and pattern.
Some 10-15\% extra tiles should be ordered than are actually required for the surface in one delivery (in order to avoid different batches of tiles). This is because

  • up to 5\% of the tiles in a Top Quality batch can be defective;
  • some tiles must be cut or drilled, which means that a certain number will have to be discarded;
  • after tiling, some tiles should be saved for any future repairs;
  • it is also important to have a sample to show the customer should they have complaints concerning the tiles.

The tile rectifying process is a process of grinding the edges of fired tiles to allow for ceramic tiles with perfectly square edges and mono-caliber. This process allows for joint-less installation with barely visible grout lines.

The shade is the colour tone that particular batch of tiles could feature. In industrial manufacturing it is almost impossible to manufacture tiles with the exact same colour shade, therefore, before packing, they are grouped together according to colour uniformity, that is to say colour shade.
The shade is often marked by a letter and a number, which is stamped onto the packaging (e.g. A48).

The work size is the manufacturing dimension of ceramic tiles. Due to manufacturing technology reasons, the tiles leaving the kiln may be of slightly different dimensions. Therefore, during the grade sorting stage, they are divided and grouped into batches of the same dimensions, according to the standards tolerance provided for by specific regulations, that is to say a slight variation in work size – a matter of mm at most.
As with the colour shade, the work size is also displayed on the packaging with a number, for example: work-size 9.

The grade is the classification of ceramic tiles, in compliance with standards and based on the tile defects. A ceramic tile can be classified as Top Quality or First Grade, meaning that the tiles is free from defects, or it can be classified as Second or Third Grade (less homogeneous, slightly chipped, etc).  

Floating floors also known as "raised floors" consist of a structure raised from the substrate and suspended on modular metallic structures, under which cabling and pipe work can be easily placed and disguised (hydraulic, electrical pipes etc.). For this reason, floating floors are mainly used in new building works and/or in renovation projects requiring maximum flexibility and easy inspection of the cabling and pipe work.
This system allows for join-less installation of ceramic tiles, and is a resistant and functional flooring suitable for offices and shops.
Marca Corona produces floating floor systems for indoor and outdoor application.

LEED standards (Leadership in Energy and Environmental Design) are parameters for sustainable building that have been developed in the USA by the US Green Building Council (USGBC), and that have been adopted in Italy thanks to the GBC Italia as well as in more than 100 countries in the world.
It is a voluntary certification system based on the allocation of credits for each of the requirements characterising the sustainability of a building. After totalling the credits, the achieved certification level can be obtained.
Ceramiche Marca Corona is an ordinary member of GBC Italia and produces ceramic tiles contributing to the allocation of LEED credits, in particular in the Marmo Ecologico and Ecoliving collections. 

Ceramiche Marca Corona offers a broad range of ceramic tiles for outdoors: Classwood, Cotto d’Autore, Easywood, I Ciottoli, Natural Living, Oldwood and SelFloor.  Completely frost-resistant, these ceramic tiles are the perfect choice for outdoor application as they have all the necessary technical features for this specific destination of use. 

Porcelain stoneware tiles by Marca Corona have a higher durability compared to alternative building materials. The expertise of Marca Corona, a company that has been producing ceramic tiles for walls and floors since 1741, the broad range of ceramic tiles, a selected customer-base offering qualified technicians for the installation and post-installation cleaning of the surface, the compliance with the standards, are all factors which ensure the absolute quality of ceramic products and the reliability of ceramic tiles.
