A ceramic is an inorganic, nonmetallic[a] stable material comprising steel, nonmetal or metalloid atoms generally held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., spectacles). Differing crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (extensively researched in ceramic executive). With such a sizable range of possible options for the structure/structure of your ceramic (e.g. all the elements nearly, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is huge, and identifiable qualities (e.g. hardness, toughness, electric conductivity, etc.) are hard to specify 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 one of these rules (e.g. piezoelectric ceramics, wine glass transition temps, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibers, while filled with ceramic materials, aren't considered to be area of the ceramic family.The term "ceramic comes from the Greek expression ????????? (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, "workers of ceramics", written in Linear B syllabic script.[5] The term "ceramic" may be used as an adjective to spell it out a material, process or product, or it might be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The earliest ceramics made by humans were pottery objects, including 27,000-year-old figurines, created from clay, either alone or blended with other materials like silica, solidified, sintered, in flames. Later ceramics were glazed and fired to create even, colored surfaces, reducing porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include home, commercial and building products, as well as an array of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic engineering, such as with semiconductors.Ceramic artifacts come with an important role in archaeology for understanding the culture, technology and patterns of individuals of days gone by. They are really among the most frequent artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Handling of gathered sherds can be steady with two main types of research: technical and traditional.Traditional analysis consists of sorting ceramic artifacts, sherds and bigger fragments into specific types predicated on style, composition, morphology and manufacturing. By creating these typologies it is possible to distinguish between different cultural styles, the purpose of the ceramic and technological state of the folks among other conclusions. Furthermore, by looking at stylistic changes of ceramics as time passes is it possible to separate (seriate) the ceramics into distinct diagnostic groups (assemblages). A comparison of ceramic artifacts with known dated assemblages allows for a chronological task of these bits.[13]The technical method of ceramic analysis requires a finer examination of the composition of ceramic artifacts and sherds to look for the way to obtain the materials and through this the possible making site. Key conditions are the structure of the clay and the temper found in the production of this article under analysis: temper is a materials put into the clay through the initial production level, and it is employed to aid the next drying out process. Types of temper include shell pieces, granite fragments and floor sherd bits called 'grog'. Temper is identified by microscopic examination of the temper material usually. Clay identification is determined by a process of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation. By estimating both clay and temper compositions, and locating an area where both are recognized to occur, an assignment of the material source can be made. From the foundation project of the artifact further investigations can be produced into the site of manufacture.
