These differ from each other, on the one hand, the above characteristics, on the other hand, the technology for their production. The name refers to the technology, which provides simultaneous firing Utel and glaze. For this technology produces a wide range of glazed products with a wide variety of physical properties. Water varies from almost zero to 15% th. Common to all of this material is used for Utel clay containing iron oxide. For spechennyh materials used exclusively fluxes on the basis of feldspar, while for the production of porous clay tiles are used with the content of carbonate (similar to clay used for the production of majolica, or metlahskoy tiles). With the right change metering components can move from spechennyh types of tiles that are low Water, and therefore intended to cover sex, including with outdoor activities, to the increasingly porous materials used to cover the floors inside the premises (instead of tiles kottoforte) or lining the walls, again indoors. These tiles do not have a special name. Its well known as: porous tiles produced single obzhigom. It may change the format: cm 10h20, 20h20 to 40h40 cm and see Find "Porous tiles produced single obzhigom" in the directory of organizations
