A ceramic can be an inorganic, nonmetallic[a] stable material comprising steel, 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., spectacles). Differing crystallinity and electron ingestion in the ionic and covalent bonds cause most ceramic materials to be good thermal and electrical insulators (thoroughly researched in ceramic engineering). With such a large selection of possible options for the structure/structure of a ceramic (e.g. almost all of the elements, all types of bonding almost, and all levels of crystallinity), the breadth of the topic is vast, and identifiable characteristics (e.g. hardness, toughness, electric powered 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 of these rules (e.g. piezoelectric ceramics, a glass transition temp, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon fiber content, while formulated with ceramic materials, are not regarded as part of the ceramic family.The word "ceramic originates 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 main "ceram-" is the Mycenaean Greek ke-ra-me-we, "staff of ceramics", written in Linear B syllabic script.[5] The word "ceramic" can be utilized as an adjective to spell it out a material, process or product, or it may be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The earliest ceramics created by humans were pottery objects, including 27,000-year-old figurines, created from clay, either alone or blended with other materials like silica, solidified, sintered, in fire. Later ceramics were glazed and fired to create even, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include local, industrial and building products, as well as a wide range of ceramic art. Within the 20th century, new ceramic materials were developed for use in advanced ceramic executive, such such as semiconductors.Ceramic artifacts own an important role in archaeology for understanding the culture, action and technology of peoples of days gone by. These are among the most typical artifacts found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Processing of accumulated sherds can be regular with two main types of analysis: technical and traditional.Traditional analysis involves sorting ceramic artifacts, sherds and bigger fragments into specific types based on style, composition, morphology and manufacturing. By creating these typologies it is possible to distinguish between different cultural styles, the goal of the ceramic and technological state of individuals 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). An evaluation of ceramic artifacts with known dated assemblages permits a chronological assignment of these bits.[13]The technical method of ceramic analysis will involve a finer study of the composition of ceramic artifacts and sherds to determine the source of the material and through this the possible making site.
