A ceramic is an inorganic, nonmetallic[a] sturdy material comprising material, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, 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 insulators (extensively researched in ceramic engineering). With such a large range of possible options for the structure/structure of any ceramic (e.g. all of the elements almost, almost all types of bonding, and all levels of crystallinity), the breadth of the subject is huge, and identifiable characteristics (e.g. hardness, toughness, electronic conductivity, etc.) are hard to identify for the group all together. 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 temp, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while made up of ceramic materials, are not regarded as area of the ceramic family.The portrayed expression "ceramic comes from the Greek phrase ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The earliest known mention of the main "ceram-" is the Mycenaean Greek ke-ra-me-we, "individuals of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to describe 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 items, including 27,000-year-old figurines, created from clay, either alone or mixed with other materials like silica, hardened, sintered, in hearth. Later ceramics were glazed and fired to create even, colored surfaces, lowering porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include domestic, industrial and building products, as well as a wide range of ceramic art. In 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, technology and patterns of peoples of the past. They are simply among the most frequent artifacts found at an archaeological site, generally by means of small fragments of broken pottery called sherds. Processing of gathered sherds can be consistent with two main types of research: technical and traditional.Traditional analysis includes sorting ceramic artifacts, sherds and greater fragments into specific types predicated on style, composition, morphology and manufacturing. By creating these typologies you'll be able to distinguish between different cultural styles, the goal of the ceramic and technological state of folks among other conclusions. Furthermore, by looking at stylistic changes of ceramics over time is it possible to separate (seriate) the ceramics into distinct diagnostic groups (assemblages). A comparison of ceramic artifacts with known dated assemblages permits a chronological task of these items.[13]The technical method of ceramic analysis entails a finer examination of the structure of ceramic artifacts and sherds to look for the way to obtain the materials and through this the possible production site. Key conditions are the structure of the clay and the temper used in the manufacture of the article under study: temper is a materials added to the clay during the initial production stage, and it is utilized to aid the next drying process. Types of temper include shell parts, granite fragments and floor sherd parts called 'grog'. Temper is identified 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 recognized to occur, an assignment of the material source can be produced. From the source project of the artifact further investigations can be made into the site of make.
