A ceramic is an inorganic, nonmetallic[a] sturdy material comprising steel, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and frequently completely amorphous (e.g., eyeglasses). Differing crystallinity and electron usage in the ionic and covalent bonds cause most ceramic materials to be good thermal and electro-mechanical insulators (thoroughly researched in ceramic engineering). With such a large range of possible options for the composition/structure of a ceramic (e.g. almost all of the elements, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable capabilities (e.g. hardness, toughness, electric powered conductivity, etc.) are hard to identify for the blended 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, a glass transition temperature, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fibers, while made up of ceramic materials, aren't regarded as part 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 reference to the root "ceram-" is the Mycenaean Greek ke-ra-me-we, "personnel 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, additionally, as the plural noun "ceramics".The initial ceramics made by humans were pottery objects, including 27,000-year-old figurines, made from clay, either alone or blended with other materials like silica, hardened, sintered, in fire. Later ceramics were glazed and terminated to set-up easy, 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. In the 20th century, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors.Ceramic artifacts offer an important role in archaeology for understanding the culture, habit and technology of individuals of days gone by. They may be among the most common artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Control of collected sherds can be steady with two main types of examination: complex and traditional.Traditional analysis will involve sorting ceramic artifacts, sherds and greater fragments into specific types based on style, composition, morphology and manufacturing. By creating these typologies it is possible to distinguish between different cultural styles, the goal of the ceramic and technological state of the individuals 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).
