A ceramic can be an inorganic, nonmetallic[a] sound material comprising metallic, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and frequently completely amorphous (e.g., glasses). Differing crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (thoroughly investigated in ceramic anatomist). With such a sizable range of possible options for the structure/structure of your ceramic (e.g. all of the elements practically, nearly all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable characteristics (e.g. hardness, toughness, electrical 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 are the norm,[1] with known exceptions to each one of these rules (e.g. piezoelectric ceramics, goblet transition temperatures, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while containing ceramic materials, aren't considered to be area of the ceramic family.The term "ceramic originates 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 root "ceram-" is the Mycenaean Greek ke-ra-me-we, "individuals of ceramics", written in Linear B syllabic script.[5] The term "ceramic" may be used as an adjective to spell it out a material, product or process, or it can be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The initial ceramics made by humans were pottery things, including 27,000-year-old figurines, created from clay, either alone or mixed with other materials like silica, hardened, sintered, in hearth. Ceramics were glazed and fired to produce soft later, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include domestic, industrial and building products, as well as a variety of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors.Ceramic artifacts own an important role in archaeology for understanding the culture, technology and patterns of individuals of the past. They are among the most common 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 analysis: technical and traditional.Traditional analysis will involve sorting ceramic artifacts, sherds and much larger fragments into specific types based on style, composition, manufacturing and morphology. By creating these typologies you'll be able to distinguish between different cultural styles, the goal of the ceramic and technological state of the communal people among other conclusions. In addition, by looking at stylistic changes of ceramics as time passes can you really separate (seriate) the ceramics into distinct diagnostic groups (assemblages). A comparison of ceramic artifacts with known dated assemblages permits a chronological task of these portions.[13]The technical method of ceramic analysis consists of a finer study of the composition of ceramic artifacts and sherds to look for the source of the material and through this the possible developing site. Key standards are the structure of the clay and the temper found in the manufacture of the article under research: temper is a material added to the clay through the initial production stage, and it can be used to aid the next drying process. Types of temper include shell items, granite fragments and ground sherd items called 'grog'. Temper is usually determined by microscopic examination of the temper material. Clay identification depends upon 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 known to occur, an assignment of the material source can be produced. From the foundation task of the artifact further investigations can be made into the site of manufacture.
