Ceramics with unique properties and high strength, are obtained by shaping and sintering inorganic materials that are not metal or metal alloys, reduced to the desired grain size. Ceramics are obtained by firing kaolin, clay and similar materials formed by the breakdown of rocks exposed to external influences at high temperatures. Ceramic (ceramic) is known by the public as a terracotta-based material.
Ceramic pots discovered in Çatalhöyük and Hacılar archaeological excavations in Anatolia are works that show the earliest histories of ceramic art. B.C. These vessels, made in 6000 BC, are decorated with iron oxide ocher. Greek potters BC. In the 6th and 5th centuries, the Romans began to produce ceramics that are easy to transport, influenced by these products, as they began to shape the pottery by changing its size and shape, and the increase in trade relations.
They are obtained by firing materials such as feldspar, clay and kaolin at high temperatures.
Refractories are glass, porcelain, brick, abrasive salts, tiles and stones.
How is Ceramic Made?
Kaolinite, tungsten carbide, silicon carbide, aluminum oxide, clay and certain pure elements are among the raw materials of ceramic material. These mixed raw materials are combined with water to be shaped and molded. It is very difficult to work with ceramics after they are made, so ceramics are usually shaped according to their desired final state. The shaped form is left to dry and then baked in an oven at a specific temperature. The ignition process provides energy to the material so that new chemical bonds and sometimes new minerals are formed. The product called bisque is what appears after the first firing of the ceramic. It is the first ignition that burns other volatile impurities and organics. It can be called glass after the second and third ignition. Decorative, functional, or waterproof glazes can be added before the first firing, or they may require a frequent subsequent second firing.
