A ceramic can be an inorganic, nonmetallic[a] solid material comprising metallic, nonmetal or metalloid atoms mostly held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and often completely amorphous (e.g., spectacles). Differing crystallinity and electron usage in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical power insulators (thoroughly researched in ceramic executive). With such a huge selection of possible options for the composition/structure of any ceramic (e.g. every one of the elements nearly, almost all types of bonding, and all degrees of crystallinity), the breadth of the subject is vast, and identifiable attributes (e.g. hardness, toughness, electronic conductivity, etc.) are hard to specify 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 temperatures, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fibre, while containing ceramic materials, aren't considered to be area of the ceramic family.The indicated word "ceramic comes 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, "workers of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to spell it out 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, created from clay, either alone or blended with other materials like silica, solidified, sintered, in hearth. Later ceramics were glazed and terminated to produce smooth, colored surfaces, reducing porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, professional and building products, as well as an array of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic executive, such such as semiconductors.Ceramic artifacts produce an important role in archaeology for understanding the culture, technology and behavior of peoples of days gone by. They are among the most typical artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Handling of collected sherds can be constant with two main types of evaluation: complex and traditional.Traditional analysis requires sorting ceramic artifacts, sherds and bigger fragments into specific types based 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 folks among other conclusions. In addition, by looking at stylistic changes of ceramics over time can you really separate (seriate) the ceramics into distinct diagnostic groups (assemblages). A comparison of ceramic artifacts with known dated assemblages permits a chronological project of these portions.[13]The technical approach to ceramic analysis consists of a finer examination of the structure of ceramic artifacts and sherds to look for the way to obtain the materials and through this the possible production site. Key standards are the structure of the clay and the temper used in the production of this article under study: temper is a materials added to the clay through the initial production level, and it is utilized to aid the next drying out process. Types of temper include shell portions, granite fragments and earth sherd pieces called 'grog'. Temper is identified by microscopic examination of the temper material usually. Clay identification is determined by a process of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation.
