FOR IMMEDIATE RELEASE
(Free-Press-Release.com) February 24, 2012 -- Earthenware
Ceramic with a water absorption rate of more than 10% after firing it at temperatures between 950 - 1150°C is known as ‘earthenware’. Earthenware is easy to work and easy to decorate. Because it is so absorbent though, it should only be used indoors to prevent weathering caused by frost. Earthenware is mainly used as glazed wall tiles.

Two different methods for manufacturing earthenware can be distinguished: In the monoporasa technology, i.e. single firing technology, the liquid glaze is applied onto the tile straight after shaping. Then the desired decoration can be applied onto the tile. In the double firing technology (biporosa) the body is fired first. Afterwards it is glazed, decorated and then fired again.

Stoneware
Stoneware has a water absorption rate of less than 3%. Stoneware is frost proof due to its low porosity. Compared to earthenware, stoneware has a higher density and a better mechanical strength. Stoneware tiles with glaze are classical ceramics for floors. Abrasion and slip resistance are determined by the technical properties of the glaze.
Unlike earthenware, stoneware is fired at temperatures between 1150 - 1300°C. Porosity can be reduced by adding fluorite and other fluxes.

Porcelain stoneware

Porcelain stoneware is characterised by its very low water absorption rate of less than 0.5%. Therefore porcelain stoneware is anadditional development of stoneware tiles, whose water absorption rate lies under 3%. Porcelain stoneware is manufactured under high pressure by dry-pressing fine processed ceramic raw materials with large amounts of quartz, feldspar and other fluxes. After this, the body is baked at high temperatures (1200 - 1300°C) in a roller passage kiln.

Porcelain stoneware has high breaking and wear resistance. At the beginning of the development, porcelain stoneware was manufactured but unglazed.

The low porosity allows polishing a tile and thereforeforming an extraordinary beautiful and brilliant surface.

By applying ceramic powders of different colours or using soluble salts, unglazed porcelain stoneware can be decorated in different ways. However, the variety of possible visual effects is limited. Therefore it becomes more and more usual to manufacture glazed and imprinted porcelain stoneware. A huge range of decors can be created due to the properties provided by this material. For instance, the most different types of stones, woods, fabrics, cork, leather etc. can be copied.

Glazed porcelain stoneware differs from glazed stoneware by a slightly higher breaking resistance and a complete frost resistance. Other properties, such as, for instance, chemical resistance, slip resistance and scratch hardness may differa lot depending on the type of surface.
