A ceramic can be an inorganic, nonmetallic[a] sound material comprising steel, nonmetal or metalloid atoms held in ionic and covalent bonds primarily. The crystallinity of ceramic materials ranges from highly oriented to semi-crystalline, and frequently completely amorphous (e.g., glasses). Varying crystallinity and electron consumption in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric insulators (thoroughly investigated in ceramic engineering). With such a big 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 degrees of crystallinity), the breadth of the subject is vast, and identifiable traits (e.g. hardness, toughness, electric powered conductivity, etc.) are hard to identify for the group as a whole. 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 temp, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fiber, while formulated with ceramic materials, aren't regarded as part of the ceramic family.The indicated expression "ceramic originates from the Greek word ????????? (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, "personnel of ceramics", written in Linear B syllabic script.[5] The word "ceramic" may be used as an adjective to describe 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 made by humans were pottery objects, including 27,000-year-old figurines, created from clay, either by itself or blended with other materials like silica, hardened, sintered, in fire. Ceramics were glazed and terminated to set-up clean 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. Within the 20th century, new ceramic materials were developed for use in advanced ceramic anatomist, such as in semiconductors.Ceramic artifacts produce an important role in archaeology for understanding the culture, technology and action 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. Control of accumulated sherds can be regular with two main types of examination: technological and traditional.Traditional analysis requires 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 purpose of the ceramic and technological state of people 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). An evaluation of ceramic artifacts with known dated assemblages permits a chronological project of these parts.[13]The technical approach to ceramic analysis entails a finer study of the composition of ceramic artifacts and sherds to determine the source of the material and through this the possible production site. Key conditions are the composition of the clay and the temper used in the produce of the article under study: temper is a materials added to the clay during the initial production level, and it can be used to aid the next drying out process. Types of temper include shell pieces, granite fragments and floor sherd parts called 'grog'. Temper is recognized 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. By estimating both clay and temper compositions, and locating a region where both are recognized to occur, an assignment of the material source can be made. From the foundation assignment of the artifact further investigations can be produced into the site of manufacture.
