A ceramic is an inorganic, nonmetallic[a] sound material comprising material, 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., eyeglasses). Varying 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 selection of possible options for the composition/structure of an ceramic (e.g. nearly all of the elements, almost all types of bonding, and all degrees of crystallinity), the breadth of the topic is huge, and identifiable features (e.g. hardness, toughness, electrical conductivity, etc.) are hard to specify 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, glass transition temperatures, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon dietary fiber, while containing ceramic materials, are not regarded as part of the ceramic family.The term "ceramic comes from the Greek term ????????? (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, "personnel of ceramics", written in Linear B syllabic script.[5] The term "ceramic" may be used as an adjective to describe a material, process or product, or it could be used as a noun, either singular, or, more commonly, as the plural noun "ceramics".The earliest ceramics created by humans were pottery objects, including 27,000-year-old figurines, created from clay, either by itself or mixed with other materials like silica, hardened, sintered, in flames. Ceramics were glazed and fired to set-up smooth later, colored surfaces, reducing porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include local, commercial and building products, as well as a wide range of ceramic art. In the 20th century, new ceramic materials were developed for use in advanced ceramic anatomist, such such as semiconductors.Ceramic artifacts own an important role in archaeology for understanding the culture, tendencies and technology of peoples of days gone by. They are among the most common artifacts 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 research: complex and traditional.Traditional analysis will involve sorting ceramic artifacts, sherds and bigger fragments into specific types based on style, composition, morphology and manufacturing. By creating these typologies you'll be able to distinguish between different cultural styles, the purpose of the ceramic and technological point out 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). 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 study of the structure of ceramic artifacts and sherds to look for the way to obtain the materials and through this the possible manufacturing site. Key criteria are the structure of the clay and the temper found in the produce of this article under review: temper is a material put into the clay through the initial production level, and it is used to aid the next drying out process. Types of temper include shell bits, granite fragments and earth sherd parts 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.
