What is porcelain
Porcelain Porcelain is one of the oldest things known to man, pottery, porcelain, ceramics and porcelain are similar tools, but the method of manufacture and the materials used and specifications and temperature used among them, where found pottery or pottery left behind by ancient man evidence However, he used to make and use pottery both as pots for eating or as utensils for preserving food. The word porcelain means clay that was burned in fire. The most famous type of porcelain is Chinese porcelain. The Chinese porcelain industry originated in the Tang Dynasty, which ruled China from 618 to 907, where Chinese porcelain consists of kaolin and pegmatite. A kind of coarse granite, the Europeans tried to imitate the Chinese porcelain industry but failed because they were unable to analyze its chemical composition.
Then in the 18th century the Chinese added bone ash to clay or clay to form a type of bone porcelain that is much stronger than ordinary Chinese porcelain. Porcelain components are the main components of the ceramics industry, where porcelain includes materials such as clay and feldspar, a metal consisting mostly of aluminum silicate, and flint, a kind of solid quartz, and silica is a compound of oxygen and silicon and are the most abundant elements in the earth's crust. The ceramic manufacturing stage starts by grinding, crushing, purifying the impurities and then mixing with water. Magnetic filtration is used to remove the iron from the dough, after which the porcelain or craftsmen form the porcelain from pots, artifacts, etc., then exposed to temperature. Gradually low to evaporate volatile contaminants and reduce shrinkage during firing At this stage the temperature is raised to 1200 ° C where there are special and developed kilns for the ceramic industry, then cooled to allow liquid glass to harden and cool, thus forming a strong bond between the granules The crystalline after t Mail and thus shaped our strong porcelain is very solid. Quality of porcelain Quality of porcelain is controlled by the nature of the raw materials added during the process of manufacturing and control of chemical composition, the distribution of particle
size, examination of the properties of viscosity, plasticity, shrinkage, strength, porosity and color, and thermal expansion are all measured, and many of these properties are monitored Control during manufacturing using statistical methods. All of the raw materials which have been mentioned can be adjusted to achieve the desired quality. Uses of porcelain Uses of porcelain or the field of use of porcelain are numerous where the ceramic industry is involved in the manufacture of beautiful vases, dishes, sculptures, and other decorative elements.
For stains better than other materials and porcelain gives a look that looks like real teeth. In the architectural field, ceramics are used in all types of buildings in floors and walls inside and outside. The porcelain is excellent in bathrooms and kitchens because it is moisture resistant and waterproof, and porcelain makes the floors very durable as can be attested by the old mosaic floors that still look beautiful after centuries of fixation on floors and walls.
