A ceramic can be an inorganic, nonmetallic[a] sound material comprising metal, nonmetal or metalloid atoms generally held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and frequently completely amorphous (e.g., glasses). Varying crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric insulators (extensively investigated in ceramic executive). With such a sizable selection of possible options for the composition/structure of any ceramic (e.g. nearly all of the elements, almost all types of bonding, and all levels of crystallinity), the breadth of the subject is huge, and identifiable qualities (e.g. hardness, toughness, electrical power conductivity, etc.) are hard to identify for the group as a whole. General properties such as high melting temperature, high hardness, poor conductivity, high moduli of elasticity, chemical resistance and low ductility will be the norm,[1] with known exceptions to each of these rules (e.g. piezoelectric ceramics, wine glass transition heat range, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass dietary fiber, while formulated with ceramic materials, are not regarded as part of the ceramic family.The term "ceramic originates from the Greek phrase ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial known mention of the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "staff of ceramics", written in Linear B syllabic script.[5] The term "ceramic" can be utilized as an adjective to describe a material, process or product, or it can be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The initial ceramics created by humans were pottery items, including 27,000-year-old figurines, made from clay, either alone or mixed with other materials like silica, solidified, sintered, in hearth. Later ceramics were glazed and fired to make smooth, colored surfaces, lowering porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, industrial and building products, as well as a variety of ceramic art. Inside the 20th hundred years, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors.Ceramic artifacts come with an important role in archaeology for understanding the culture, habit and technology of peoples of the past. They are among the most frequent artifacts to be found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Processing of accumulated sherds can be consistent with two main types of research: complex and traditional.Traditional analysis involves sorting ceramic artifacts, sherds and much larger fragments into specific types predicated on style, composition, manufacturing and morphology. By creating these typologies you'll be able to distinguish between different cultural styles, the purpose of the ceramic and technological status of the public people among other conclusions. Furthermore, by looking at stylistic changes of ceramics over time can you really separate (seriate) the ceramics into distinct diagnostic groups (assemblages). An evaluation of ceramic artifacts with known dated assemblages permits a chronological assignment of these items.[13]The technical method of ceramic analysis entails a finer study of the composition of ceramic artifacts and sherds to determine the way to obtain the materials and through this the possible making site. Key criteria are the structure of the clay and the temper found in the manufacture of this article under research: temper is a material put into the clay during the initial production level, and it is utilized to aid the next drying process. Types of temper include shell parts, granite fragments and surface sherd parts called 'grog'. Temper is discovered by microscopic examination of the temper material usually. Clay identification depends upon an activity of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation. By estimating both clay and temper compositions, and locating a region where both are known to occur, an task of the materials source can be made. From the foundation task of the artifact further investigations can be made in to the site of manufacture.
