  1. KAOLIN

    White clay used for the manufacturing of porcelain.

  2. KLINKER (or clinker)

    Small size tiles with high thickness whose mix is made of ordinary clays and kaolin, feldspar and non-plastic materials.

    It differs from porcelain stoneware as it has a heterogeneous body and is less vitrified but, just like porcelain stoneware, it is resistant to frost and to chemicals and has a high mechanical bending strength.

    Klinker products are obtained via pressing or extrusion and fired at more than 1200°C with long firing cycles.

     

    Klinker tiles are used for indoor and outdoor flooring. The main producer of this product is Germany, the country where it was invented in 1930.
