Many of the recent changes in tile are the result of improvements and refinements made to the strength of the tile body (bisque) and the all important glaze, which is inevitably tougher. This has resulted in the appearance of a new floor tile grade. Grade V (refer to table on facing page).
Nowadays White Body tile may also be referred to as Monocottura Chiara, or single fired White Body tile. These tiles are produced worldwide, with the centre of production and development based in Italy. Typically produced from iron-free clays, imported from France or Germany, the bisque (body) varies in colour from light grey to beige.
Predominently produced as floor tiles, the finished product has low water absorption (less than 3%) and is widely used for both interior and exterior applications. Normal sizes are 30x30cms or 40x40cms. They may also be produced as large as 60x60cms for special projects (i.e. ventilated walls).
Double fired, typical White Body Earthenware tile contains a wide variety of materials, principally kaolinite, the finished product exhibits high abrasion resistance; whilst Monocottura Chiara offers high frost, weather and chemical resistance.
