Vintage Original Ron Gordon Designs, Inc. Four Piece Ceramic Cottage
A ceramic is an inorganic, nonmetallic[a] sturdy material comprising metal, nonmetal or metalloid atoms generally held in ionic and covalent bonds. The crystallinity of ceramic materials ranges from oriented to semi-crystalline highly, and frequently completely amorphous (e.g., eyeglasses). Varying crystallinity and electron intake in the ionic and covalent bonds cause most ceramic materials to be good thermal and electric powered insulators (extensively researched in ceramic executive). With such a sizable selection of possible options for the composition/structure of any ceramic (e.g. all the elements nearly, almost all types of bonding, and all levels of crystallinity), the breadth of the subject is great, and identifiable characteristics (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, cup transition heat range, superconductive ceramics, etc.). Many composites, such as carbon and fiberglass fibre, while containing ceramic materials, aren't considered to be part of the ceramic family.The indicated word "ceramic comes from the Greek word ????????? (keramikos), "of pottery" or "for pottery",[3] from ??????? (keramos), "potter's clay, tile, pottery".[4] The initial known reference to the main "ceram-" is the Mycenaean Greek ke-ra-me-we, "staff of ceramics", written in Linear B syllabic script.[5] The term "ceramic" can be utilized as an adjective to spell it out a material, product or process, or it might be used as a noun, either singular, or, additionally, as the plural noun "ceramics".The earliest ceramics created by humans were pottery things, including 27,000-year-old figurines, created from clay, either alone or mixed with other materials like silica, hardened, sintered, in fire. Later ceramics were glazed and fired to generate soft, colored surfaces, lowering porosity by using glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates.[7] Ceramics now include home, industrial and building products, as well as a wide range of ceramic art. Within the 20th hundred years, new ceramic materials were developed for use in advanced ceramic executive, such as with semiconductors.Ceramic artifacts own an important role in archaeology for understanding the culture, habit and technology of peoples of the past. They are among the most frequent artifacts to be found at an archaeological site, generally by means of small fragments of broken pottery called sherds. Control of accumulated sherds can be steady with two main types of research: technical and traditional.Traditional analysis requires sorting ceramic artifacts, sherds and larger fragments into specific types predicated 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 scientific point out of the social 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 pieces.[13]The technical method of ceramic analysis involves a finer study of the structure of ceramic artifacts and sherds to look for the source of the materials and through this the possible developing site.
