EUGENE HŐN : CERAMIC ARTIST: Contemporary art and design In China
A ceramic can be an inorganic, nonmetallic[a] stable material comprising material, 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 ingestion in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (extensively investigated in ceramic engineering). With such a huge selection of possible options for the structure/structure of an ceramic (e.g. all the elements practically, nearly all types of bonding, and all degrees of crystallinity), the breadth of the topic is great, and identifiable capabilities (e.g. hardness, toughness, electrical power 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 temperatures, superconductive ceramics, etc.). Many composites, such as fiberglass and carbon dietary fiber, while containing ceramic materials, aren't regarded as area of the ceramic family.The indicated phrase "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, "individuals of ceramics", written in Linear B syllabic script.[5] The word "ceramic" can be utilized as an adjective to describe a material, product or process, or it may be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The earliest ceramics made by humans were pottery objects, including 27,000-year-old figurines, made from clay, either alone or blended with other materials like silica, solidified, sintered, in flame. Later ceramics were glazed and fired to build smooth, colored surfaces, reducing porosity by using glassy, amorphous ceramic coatings together with the crystalline ceramic substrates.[7] Ceramics now include domestic, professional and building products, as well as a variety of ceramic art. Within the 20th century, new ceramic materials were developed for use in advanced ceramic anatomist, such as with semiconductors.Ceramic artifacts come with an important role in archaeology for understanding the culture, technology and action of peoples of the past. They are simply among the most common artifacts to be found at an archaeological site, generally in the form of small fragments of broken pottery called sherds. Control of accumulated sherds can be constant with two main types of analysis: technical and traditional.Traditional analysis requires sorting ceramic artifacts, sherds and greater 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 the individuals among other conclusions. Furthermore, 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 bits.[13]The technical method of ceramic analysis includes a finer examination of the structure of ceramic artifacts and sherds to determine the way to obtain the materials and through this the possible processing site. Key conditions are the structure of the clay and the temper used in the produce of this article under review: temper is a materials added to the clay during the initial production stage, and it can be used to aid the next drying out process. Types of temper include shell items, granite fragments and earth sherd items called 'grog'. Temper is discovered by microscopic examination of the temper material usually. Clay identification is determined by an activity 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 project of the material source can be produced. From the source project of the artifact further investigations can be produced in to the site of production.
