Soft-paste Porcelain
Soft-paste porcelain (sometimes simply "soft paste", or "artificial porcelain") is a type of ceramic material in pottery, usually accepted as a type of porcelain. It is weaker than "true" hard-paste porcelain, and does not require either its high firing temperatures or special mineral ingredients. There are many types, using a range of materials. The material originated in the attempts by many European potters to replicate hard-paste Chinese export porcelain, especially in the 18th century, and the best versions match hard-paste in whiteness and translucency, but not in strength. But the look and feel of the material can be highly attractive, and it can take painted decoration very well. The ingredients varied considerably, but always included clay, often ball clay, and often ground glass, bone ash, soapstone (steatite), flint, and quartz. They rarely included the key ingredients necessary for hard-paste, china clay including kaolin, or the English china stone, although some manu ...

Hard-paste Porcelain
Hard-paste porcelain, sometimes called "true porcelain", is a ceramic material that was originally made from a compound of the feldspathic rock petuntse and kaolin fired at a very high temperature, usually around 1400 °C. It was first made in China around the 7th or 8th century and has remained the most common type of Chinese porcelain. Fleming, John & Hugh Honour. (1977) ''The Penguin Dictionary of Decorative Arts. '' London: Allen Lane, p. 622. From the Middle Ages onwards, it was very widely exported and admired by other cultures and fetched huge prices on foreign markets. Eventually Korean porcelain developed in the 14th century and Japanese porcelain in the 17th, but other cultures were unable to learn or reproduce the secret of its formula in terms of materials and firing temperature until it was worked out in Europe in the early 18th century and suitable mineral deposits of kaolin, feldspar, and quartz were discovered. This soon led to a large production in fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jar MET DP168331 (cropped)
A jar is a rigid, cylindrical or slightly conical container, typically made of glass, ceramic, or plastic, with a wide mouth or opening that can be closed with a lid, screw cap, lug cap, Bung, cork stopper, roll-on cap, crimp-on cap, press-on cap, Shrink wrap, plastic shrink, heat sealed lidding film, an inner seal, a tamper-evident band, or other suitable means. The English word "jar" originates from the Arabic word ''jarra'', which means an earthen pot or vessel. Background Jars can be used to hold solids too large to be removed from, or liquids too Viscosity, viscous to be poured through a bottle's neck; these may be foods, cosmetics, medications, or Chemical substance, chemicals. Glass jars—among which the most popular is the mason jar—can be used for storing and preserving items as diverse as Fruit preserves, jam, Pickled cucumber, pickled gherkin, other pickles, marmalade, sun-dried tomatoes, olives, Jalapeño, jalapeño peppers, chutneys, pickled eggs, honey, and ma ...

Vienna Porcelain
Vienna porcelain is the product of the Vienna Porcelain Manufactory (German: ''Kaiserlich privilegierte Porcellain Fabrique''), a porcelain manufacturer in Alsergrund in Vienna, Austria. It was founded in 1718 and continued until 1864. The firm was Europe's second-oldest porcelain factory after Meissen porcelain, and for 25 years the two remained the only European producers. Initially it was a private enterprise, founded by Claude du Paquier, an official of the Viennese Imperial court, but in 1744 it was rescued from financial difficulties when bought by the Empress Maria Theresa, and thereafter remained an asset of the emperors. The wares from the earlier, private period before 1744 are the most sought-after today, if only because production was lower and so the pieces are much more rare. These are often called Du Paquier porcelain from the Du Paquier factory. The other high point, "perhaps the factory's most glamorous period", was from 1784 to 1805 when a variety of innovati ...

Feldspar
Feldspar ( ; sometimes spelled felspar) is a group of rock-forming aluminium tectosilicate minerals, also containing other cations such as sodium, calcium, potassium, or barium. The most common members of the feldspar group are the ''plagioclase'' (sodium-calcium) feldspars and the ''alkali'' (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust and 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Etymology The name ''feldspar'' derives from the German , a compound of the words ' ("field") and ("flake"). had long been used as the word for "a rock easily cleaved into flakes"; was introduced in the 18th century as a more specific term, referring perhaps to its comm ...

Medici Porcelain
Medici porcelain was the first successful attempt in Europe to make imitations of Chinese porcelain, though it was soft-paste porcelain rather than the hard-paste made in Asia. The experimental manufactory housed in the Casino of San Marco in Florence existed between 1575 and 1587 under the patronage of Francesco I de' Medici, Grand Duke of Tuscany. Surviving examples are extremely rare, numbering 59 according to the Metropolitan Museum of Art. A painted mark of Brunelleschi's dome and a capital letter F appear on the underside of some pieces; others bear the Medici ''palle'', the balls that are the Medici heraldic charge. Never a commercial venture, Medici porcelains were sometimes given as diplomatic gifts; for example, surviving pieces bear the arms of Philip II of Spain. In 1995, a vase dated to around 1575, was sold in Paris for FRF6,430,000 (at the time equivalent to £870,000). In 1999, a cruet dated circa 1575 was auctioned at Christie's for £287,000.

Lime (mineral)
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities in the manufacture of steel and as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, for sugar refining, and other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous ...

Soapstone
Soapstone (also known as steatite or soaprock) is a talc-schist, which is a type of metamorphic rock. It is composed largely of the magnesium-rich mineral talc. It is produced by dynamothermal metamorphism and metasomatism, which occur in subduction zones, changing rocks by heat and pressure, with influx of fluids but without melting. It has been a carving medium for thousands of years. Terminology The definitions of the terms "steatite" and "soapstone" vary with the field of study. In geology, steatite is a rock that is, to a very large extent, composed of talc. The mining industry defines steatite as a high-purity talc rock that is suitable for the manufacturing of, for example, insulators; the lesser grades of the mineral can be called simply "talc rock". Steatite can be used both in lumps ("block steatite", "lava steatite", "lava grade talc"), and in the ground form. While the geologists logically will use "steatite" to designate both forms, in the industry, "steatite" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frit
A frit is a ceramic composition that has been fused, quenched, and granulated. Frits form an important part of the batches used in compounding enamels and ceramic glazes; the purpose of this pre-fusion is to render any soluble and/or toxic components insoluble by causing them to combine with silica and other added oxides.''Dictionary of Ceramics'' (3rd Edition) Edited by Dodd, A. Murfin, D. Institute of Materials. 1994. However, not all glass that is fused and quenched in water is frit, as this method of cooling down very hot glass is also widely used in glass manufacture. According to the '' OED'', the origin of the word "frit" dates back to 1662 and is "a calcinated mixture of sand and fluxes ready to be melted in a crucible to make glass". Nowadays, the unheated raw materials of glass making are more commonly called "glass batch". In antiquity, frit could be crushed to make pigments or shaped to create objects. It may also have served as an intermediate material in the manu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass
Glass is an amorphous (non-crystalline solid, non-crystalline) solid. Because it is often transparency and translucency, transparent and chemically inert, glass has found widespread practical, technological, and decorative use in window panes, tableware, and optics. Some common objects made of glass are named after the material, e.g., a Tumbler (glass), "glass" for drinking, "glasses" for vision correction, and a "magnifying glass". Glass is most often formed by rapid cooling (quenching) of the Melting, molten form. Some glasses such as volcanic glass are naturally occurring, and obsidian has been used to make arrowheads and knives since the Stone Age. Archaeological evidence suggests glassmaking dates back to at least 3600 BC in Mesopotamia, Ancient Egypt, Egypt, or Syria. The earliest known glass objects were beads, perhaps created accidentally during metalworking or the production of faience, which is a form of pottery using lead glazes. Due to its ease of formability int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Porcelain
Chinese ceramics are one of the most significant forms of Chinese art and ceramics globally. They range from construction materials such as bricks and tiles, to hand-built pottery vessels fired in bonfires or kilns, to the sophisticated Chinese porcelain wares made for the imperial court and for export. The oldest known pottery in the world was made during the Paleolithic at Xianrendong Cave, Jiangxi Province, China. Chinese ceramics show a continuous development since pre-dynastic times. Porcelain was a Chinese invention and is so identified with China that it is still called "china" in everyday English usage. Most later Chinese ceramics, even of the finest quality, were made on an industrial scale, thus few names of individual potters were recorded. Many of the most important kiln workshops were owned by or reserved for the emperor, and large quantities of Chinese export porcelain were exported as diplomatic gifts or for trade from an early date, initially to East Asia a ...

Saint Cloud Bowl Soft Porcelain With Blue Decorations Under Glaze 1700 1710
In Christian belief, a saint is a person who is recognized as having an exceptional degree of holiness, likeness, or closeness to God. However, the use of the term ''saint'' depends on the context and denomination. In Anglican, Oriental Orthodox, and Lutheran doctrine, all of their faithful deceased in Heaven are considered to be saints, but a selected few are considered worthy of greater honor or emulation. Official ecclesiastical recognition, and veneration, is conferred on some denominational saints through the process of canonization in the Catholic Church or glorification in the Eastern Orthodox Church after their approval. In many Protestant denominations, and following from Pauline usage, ''saint'' refers broadly to any holy Christian, without special recognition or selection. While the English word ''saint'' (deriving from the Latin ) originated in Christianity, historians of religion tend to use the appellation "in a more general way to refer to the state of special h ...

Cambrian Pottery
The Cambrian Pottery was founded in 1764 by William Coles in Swansea, Glamorganshire, Wales. In 1790, John Coles, son of the founder, went into partnership with George Haynes, who introduced new business strategies based on the ideas of Josiah Wedgwood. Lewis Weston Dillwyn became a partner in 1802 and sole owner when George Haynes left the pottery in 1810. In 1811 Dillwyn took T.& J. Bevington into partnership, the company becoming known as Dillwyn & Co. Initially "its main product was coarse redware for farm and domestic use, though creamware and lead-glazed earthenware were also made". But Dillwyn, who also wrote naturalist books, was keen to move upmarket and employed the artist William Weston Young from 1806, and also Thomas Rothwell (1740-1807). Between 1814 and about 1822, the famous Swansea china or Swansea porcelain was made there. Porcelain After William Billingsley, then owner of the Nantgarw porcelain factory, asked the Board of Trade for help, as he was ...
