A ceramic can be an inorganic, nonmetallic[a] sturdy material comprising metallic, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. 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 electronic insulators (extensively explored in ceramic executive). With such a huge selection of possible options for the composition/structure of a ceramic (e.g. every one of the elements practically, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable features (e.g. hardness, toughness, electric 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 are the norm,[1] with known exceptions to each one of these rules (e.g. piezoelectric ceramics, a glass transition temp, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibre, while made up of ceramic materials, are not regarded as part of the ceramic family.The indicated phrase "ceramic comes from the Greek term ????????? (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, "staff 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 things, including 27,000-year-old figurines, made from clay, either by itself or mixed with other materials like silica, hardened, sintered, in flame. Later ceramics were glazed and terminated to build simple, colored surfaces, lessening porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, professional and building products, as well as a variety of ceramic art. In the 20th hundred years, new ceramic materials were developed for use in advanced ceramic executive, such as in semiconductors.Ceramic artifacts come with an important role in archaeology for understanding the culture, technology and habit of individuals of the past. These are among the most frequent artifacts to be found at an archaeological site, generally by means of small fragments of broken pottery called sherds. Processing of collected sherds can be constant with two main types of examination: technical and traditional.Traditional analysis entails sorting ceramic artifacts, sherds and bigger 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 state of individuals among other conclusions. In addition, by looking at stylistic changes of ceramics over time is it possible to separate (seriate) the ceramics into distinct diagnostic groups (assemblages).

Types of temper include shell items, granite fragments and ground sherd portions called 'grog'. Temper is usually determined by microscopic examination of the temper material. Clay identification depends upon an activity of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation.
