A ceramic is an inorganic, nonmetallic[a] sturdy material comprising metal, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and often completely amorphous (e.g., spectacles). 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 engineering). With such a huge selection of possible options for the composition/structure of your ceramic (e.g. all of the elements almost, all sorts of bonding almost, and all levels of crystallinity), the breadth of the topic is great, and identifiable qualities (e.g. hardness, toughness, electronic conductivity, etc.) are hard to designate 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 will be the norm,[1] with known exceptions to each one of these rules (e.g. piezoelectric ceramics, glass transition heat range, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon dietary fiber, while comprising ceramic materials, aren't regarded as area of the ceramic family.The indicated phrase "ceramic comes 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, "individuals of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to spell it out a material, process or product, or it could be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The initial ceramics made by humans were pottery items, including 27,000-year-old figurines, created from clay, either alone or mixed with other materials like silica, hardened, sintered, in open fire. Ceramics were glazed and fired to make even later, colored surfaces, decreasing porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include domestic, commercial 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 with semiconductors.Ceramic artifacts own an important role in archaeology for understanding the culture, technology and action of individuals of the past. They can be among the most frequent artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Handling of collected sherds can be regular with two main types of examination: complex and traditional.Traditional analysis requires sorting ceramic artifacts, sherds and larger 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 goal of the ceramic and technological status of the communal 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). An evaluation of ceramic artifacts with known dated assemblages permits a chronological assignment of these pieces.[13]The technical approach to ceramic analysis entails a finer study of the composition of ceramic artifacts and sherds to look for the way to obtain the material and through this the possible making site. Key requirements are the composition of the clay and the temper used in the produce of the article under research: temper is a materials added to the clay through the initial production level, and it is used to aid the subsequent drying out process. Types of temper include shell pieces, granite fragments and surface sherd pieces called 'grog'. Temper is usually identified by microscopic examination of the temper material. Clay identification is determined by an activity of refiring the ceramic, and assigning a color to it using Munsell Soil Color notation.
