A ceramic can be an inorganic, nonmetallic[a] solid 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). Varying crystallinity and electron utilization in the ionic and covalent bonds cause most ceramic materials to be good thermal and electronic insulators (extensively researched in ceramic engineering). With such a large range of possible options for the composition/structure of any ceramic (e.g. almost all of the elements, all types of bonding almost, and all degrees of crystallinity), the breadth of the topic is huge, and identifiable qualities (e.g. hardness, toughness, electric powered conductivity, etc.) are hard to specify for the mixed 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 of these rules (e.g. piezoelectric ceramics, glass transition heat range, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fibre, while filled with ceramic materials, are not regarded as area of the ceramic family.The term "ceramic originates from the Greek expression ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The earliest known mention of the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "personnel of ceramics", written in Linear B syllabic script.[5] The term "ceramic" can be utilized as an adjective to describe a material, product or process, or it might 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 blended with other materials like silica, hardened, sintered, in fireplace. Later ceramics were glazed and fired to generate even, colored surfaces, lowering porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include domestic, professional and building products, as well as a wide range of ceramic art. Within the 20th century, new ceramic materials were developed for use in advanced ceramic anatomist, such as in semiconductors.Ceramic artifacts have an important role in archaeology for understanding the culture, technology and patterns of peoples of days gone by. They are simply among the most frequent artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Processing of accumulated sherds can be regular with two main types of analysis: technical and traditional.Traditional analysis consists of sorting ceramic artifacts, sherds and bigger fragments into specific types predicated on style, composition, manufacturing and morphology. 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. In addition, by looking at stylistic changes of ceramics as time passes is it possible to separate (seriate) the ceramics into distinct diagnostic groups (assemblages). An evaluation of ceramic artifacts with known dated assemblages allows for a chronological project of these parts.[13]The technical method of ceramic analysis entails a finer examination of the composition of ceramic artifacts and sherds to look for the source of the materials and through this the possible manufacturing site. Key conditions are the composition of the clay and the temper used in the produce of the article under review: temper is a materials put into the clay during the initial production level, and it can be used to aid the subsequent drying process. Types of temper include shell pieces, granite fragments and ground sherd parts called 'grog'. Temper is usually identified by microscopic examination of the temper material. Clay identification is determined by an activity of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation.
