A ceramic is an inorganic, nonmetallic[a] solid material comprising metallic, nonmetal or metalloid atoms primarily held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and often completely amorphous (e.g., glasses). Differing crystallinity and electron ingestion in the ionic and covalent bonds cause most ceramic materials to be good thermal and electro-mechanical insulators (thoroughly researched in ceramic anatomist). With such a huge range of possible options for the structure/structure of the ceramic (e.g. every one of the elements practically, almost all types of bonding, and all levels of crystallinity), the breadth of the subject is vast, and identifiable qualities (e.g. hardness, toughness, electric 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 of these rules (e.g. piezoelectric ceramics, wine glass transition temps, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while including ceramic materials, are not considered to be area of the ceramic family.The word "ceramic originates from the Greek expression ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial known reference to the main "ceram-" is the Mycenaean Greek ke-ra-me-we, "personnel 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 initial ceramics created by humans were pottery objects, including 27,000-year-old figurines, made from clay, either by itself or mixed with other materials like silica, solidified, sintered, in flames. Later ceramics were glazed and terminated to make easy, colored surfaces, lessening porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include local, industrial and building products, as well as an array of ceramic art. Inside the 20th hundred years, new ceramic materials were developed for use in advanced ceramic engineering, such as in semiconductors.Ceramic artifacts provide an important role in archaeology for understanding the culture, patterns and technology of individuals of the past. They can be among the most typical artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Handling of accumulated sherds can be steady with two main types of research: technical and traditional.Traditional analysis involves sorting ceramic artifacts, sherds and larger 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 people among other conclusions. Furthermore, by looking at stylistic changes of ceramics as time passes 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 project of these bits.[13]The technical approach to ceramic analysis requires a finer examination of the structure of ceramic artifacts and sherds to determine the way to obtain the materials and through this the possible creation site. Key standards are the composition of the clay and the temper found in the make of this article under analysis: temper is a material added to the clay through the initial production stage, and it is employed to aid the next drying process. Types of temper include shell parts, granite fragments and earth sherd portions called 'grog'. Temper is usually determined by microscopic examination of the temper material. Clay identification is determined by a process of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation. By estimating both the temper and clay compositions, and locating an area where both are recognized to occur, an task of the material source can be produced. From the foundation project of the artifact further investigations can be made into the site of make.
