Wiktionary
Wiktionary (, ; , ; rhyming with "dictionary") is a multilingual, web-based project to create a free content dictionary of terms (including words, phrases, proverbs, linguistic reconstructions, etc.) in all natural languages and in a number of artificial languages. These entries may contain definitions, images for illustration, pronunciations, etymologies, inflections, usage examples, quotations, related terms, and translations of terms into other languages, among other features. It is collaboratively edited via a wiki. Its name is a portmanteau of the words ''wiki'' and ''dictionary''. It is available in languages and in Simple English. Like its sister project Wikipedia, Wiktionary is run by the Wikimedia Foundation, and is written collaboratively by volunteers, dubbed "Wiktionarians". Its wiki software, MediaWiki, allows almost anyone with access to the website to create and edit entries. Because Wiktionary is not limited by print space considerations, most of Wiktiona ...

Ceramic
A ceramic is any of the various hard, brittle, heat-resistant, and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. The earliest ceramics made by humans were fired clay bricks used for building house walls and other structures. Other pottery objects such as pots, vessels, vases and figurines were made from clay, either by itself or mixed with other materials like silica, hardened by sintering in fire. Later, ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates. Ceramics now include domestic, industrial, and building products, as well as a wide range of materials developed for use in advanced ceramic engineering, such as semiconductors. The word '' ceramic'' comes from the Ancient Greek word (), meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crock (dishware)
A crock is a pottery container sometimes used for food or water, synonymous with the word "pot", and sometimes used for chemicals. Derivative terms include " crockery" and " crock-pot". Crocks, or "preserving crocks", were used in household kitchens before refrigeration to hold and preserve foods such as butter, salted meats, and pickled vegetables. Crocks are made from stoneware, which is a nonporous ceramic that is water-tight, even without glaze. Larger crocks (20-30 gallons) are used for curing meats. The meat is covered with a brine made of water, sugar, salt, and a small amount of sodium nitrate or salt peter. The meat is kept submerged in the brine by two semicircle weights designed to fit inside the crock. The crocks are then topped with a lid and stored in a cool, dry location. Smaller crocks (1-10 gallons) are commonly used for preserving vegetables such as cucumbers for pickles, and cabbage for sauerkraut. Preserving food in this manner allows people to keep su ...

Glaze Defects
Glaze defects are any flaws in the surface quality of a ceramic glaze, its physical structure or its interaction with the body. Glaze and body mismatch Certain glaze defects are a result of differences in the thermal expansion coefficient of the glaze and the clay body. Crazing Crazing is a spider web pattern of cracks penetrating the glaze. It is caused by tensile stresses greater than the glaze is able to withstand."Ceramics Glaze Technology". J. R. Taylor, A. C. Bull. ''Institute Of Ceramics / Pergamon Press.'' 1986. Common reasons for such stresses are: a mismatch between the thermal expansions of glaze and body; from moisture expansion of the body; and in the case of glazed tiles fixed to a wall, movement of the wall or of the bonding material used to fix the tile to the wall.Dictionary Of Ceramics. Arthur Dodd & David Murfin. 3rd edition. ''The Institute Of Minerals.'' 1994. The cracks can allow the ingress of water into the cracks. Once fired, ware tends to be more resista ...

Pyrometric Cone
Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials in a kiln. The cones, often used in sets of three, are positioned in a kiln with the wares to be fired and, because the individual cones in a set soften and fall over at different temperatures, they provide a visual indication of when the wares have reached a required state of maturity, a combination of time and temperature. Pyrometric cones give a ''temperature equivalent''; they are not simple temperature-measuring devices. Definition The pyrometric cone is "A pyramid with a triangular base and of a defined shape and size; the "cone" is shaped from a carefully proportioned and uniformly mixed batch of ceramic materials so that when it is heated under stated conditions, it will bend due to softening, the tip of the cone becoming level with the base at a definitive temperature. Pyrometric cones are made in series, the temperature interval between the successive con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...
