Bone China
Bone china is a type of ceramic that is composed of bone ash, feldspathic material, and kaolin. It has been defined as "ware with a translucent body" containing a minimum of 30% of phosphate derived from animal bone and calculated calcium phosphate. Bone china is the strongest of the porcelain or china ceramics, having very high mechanical and physical strength and chip resistance, and is known for its high levels of whiteness and translucency.Ozgundogdu, Feyza Cakir. “Bone China from Turkey” Ceramics Technical; May2005, Issue 20, p29-32. Its high strength allows it to be produced in thinner cross-sections than other types of porcelain. Like stoneware, it is vitrified, but is translucent due to differing mineral properties. In the mid-18th century, English potters had not succeeded in making hard-paste porcelain (as made in East Asia and Meissen porcelain), but found bone ash a useful addition to their soft-paste porcelain mixtures, giving strength. This became standard at th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Doulton
Royal Doulton is an English ceramic and home accessories manufacturer that was founded in 1815. Operating originally in Vauxhall, London, and later moving to Lambeth, in 1882 it opened a factory in Burslem, Stoke-on-Trent, in the centre of English pottery. From the start, the backbone of the business was a wide range of utilitarian wares, mostly stonewares, including storage jars, tankards and the like, and later extending to pipes for drains, lavatories and other bathroom ceramics. From 1853 to 1901, its wares were marked Doulton & Co., then from 1901, when a royal warrant was given, Royal Doulton. It always made some more decorative wares, initially still mostly stoneware, and from the 1860s, the firm made considerable efforts to get a reputation for design, in which it was largely successful, as one of the first British makers of art pottery. Initially this was done through artistic stonewares made in Lambeth, but in 1882 the firm bought a Burslem factory, which was main ...

Plasticity (physics)
In physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent Deformation (engineering), deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from Elasticity (physics), elastic behavior to plastic behavior is known as Yield (engineering), yielding. Plastic deformation is observed in most materials, particularly metals, soils, Rock (geology), rocks, concrete, and foams. However, the physical mechanisms that cause plastic deformation can vary widely. At a crystalline scale, plasticity in metals is usually a consequence of dislocations. Such defects are relatively rare in most crystalline materials, but are numerous in some and part of their crystal structure; in such cases, plastic crystallinity can res ...

Portmeirion Pottery
Portmeirion is a British pottery company based in Stoke-on-Trent, England. History Portmeirion Pottery began in 1960 when pottery designer Susan Williams-Ellis (daughter of Sir Clough Williams-Ellis, who created the Italian-style Portmeirion Village in North Wales) and her husband, Euan Cooper-Willis, took over a small pottery-decorating company in Stoke-on-Trent called A. E. Gray Ltd, also known as Gray's Pottery. Susan Williams-Ellis had been working with A.E. Gray for some years, commissioning designs to sell at the gift shop in Portmeirion Village, the items bearing the backstamp "Gray's Pottery Portmeirionware". In 1961, the couple purchased a second pottery company, Kirkhams Ltd, that had the capacity to manufacture pottery, and not only decorate it. These two businesses were combined and Portmeirion Potteries Ltd was born. Susan Williams-Ellis' early Portmeirion designs included Malachite (1960), Moss Agate (1961) and Talisman (1962). In 1963, she created the popular des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Receivership
In law, receivership is a situation in which an institution or enterprise is held by a receiver—a person "placed in the custodial responsibility for the property of others, including tangible and intangible assets and rights"—especially in cases where a company cannot meet its financial obligations and is said to be insolvent.Philip, Ken, and Kerin Kaminski''Secured Lender'', January/February 2007, Vol. 63 Issue 1, pages 30-34,36. The receivership remedy is an equitable remedy that emerged in the English chancery courts, where receivers were appointed to protect real property. Receiverships are also a remedy of last resort in litigation involving the conduct of executive agencies that fail to comply with constitutional or statutory obligations to populations that rely on those agencies for their basic human rights. Receiverships can be broadly divided into two types: *Those related to insolvency or enforcement of a security interest. *Those where either **One is Incapable of ...

China Clay
Kaolinite ( ) is a clay mineral, with the chemical composition Al2 Si2 O5( OH)4. It is an important industrial mineral. It is a layered silicate mineral, with one tetrahedral sheet of silica () linked through oxygen atoms to one octahedral sheet of alumina () octahedra. Rocks that are rich in kaolinite are known as kaolin () or china clay. Kaolin is occasionally referred to by the antiquated term lithomarge, from the Ancient Greek ''litho-'' and Latin ''marga'', meaning 'stone of marl'. Presently the name lithomarge can refer to a compacted, massive form of kaolin. The name ''kaolin'' is derived from Gaoling (), a Chinese village near Jingdezhen in southeastern China's Jiangxi Province. The name entered English in 1727 from the French version of the word: , following François Xavier d'Entrecolles's reports on the making of Jingdezhen porcelain. Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China Stone
China stone is a medium grained, feldspar-rich partially kaolinised granite characterized by the absence of iron-bearing minerals.Cornwall County Council website, ''China clay and china stone'' undated, URL retrieved on 14 September 2007 It is mainly used for making , hence the name, and coatings for paper. Its discovery in the mid-18th century was a crucial event in the development of the English porcelain industry. The |
Calcining
Calcination refers to thermal treatment of a solid chemical compound (e.g. mixed carbonate ores) whereby the compound is raised to high temperature without melting under restricted supply of ambient oxygen (i.e. gaseous O2 fraction of air), generally for the purpose of removing impurities or volatile substances and/or to incur thermal decomposition. The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone (calcium carbonate) through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO3(s) → CaO(s) + CO2(g). Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting. Industrial calcination generally emits carbon dioxide (), making it a major contributor to climate change. A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 °C, or 1000–2100 °F) within a controlled ...

Josiah Spode II
Josiah Spode (23 March 1733 – 18 August 1797) was an English potter and the founder of the English Spode pottery works which became famous for the high quality of its wares. He is often credited with the establishment of blue underglaze transfer printing in Staffordshire in 1781–84, and with the definition and introduction in c. 1789–91 of the improved formula for bone china (a form of soft-paste porcelain) which thereafter remained the standard for all English wares of this kind. Early life Josiah Spode was born in Lane Delph, Fenton, Staffordshire. Spode was a pauper's son and also a pauper's orphan at the age of six. In 1745 his elder sister Ann married Ambrose Gallimore, who in 1754 obtained the lease of the Caughley porcelain factory near Broseley. Spode was taken on as a worker by potter Thomas Whieldon in November (Martinmas) 1749, and remained with him until 1754. In that year, on 8 September, Josiah married Ellen Finley at Stoke on Trent, and his eldest son Josi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Bow, London
Bow () is an area of East London within the London Borough of Tower Hamlets. It is primarily a built-up and mostly residential area and is east of Charing Cross. It was in the traditional county of Middlesex but became part of the County of London following the passing of the Local Government Act 1888. "Bow" is an abbreviation of the medieval name Stratford-at-Bow, in which "Bow" refers to the bowed bridge built here in the early 12th century. Bow contains parts of both Victoria Park and the Queen Elizabeth Olympic Park. Old Ford and Fish Island are localities within Bow, but Bromley-by-Bow (historically and officially just "Bromley") immediately to the south, is a separate district. These distinctions have their roots in historic parish boundaries. Bow underwent extensive urban regeneration including the replacement or improvement of council homes, with the impetus given by the staging of the 2012 Olympic Games at nearby Stratford. History Bow formed a part of the mediev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
