Andrew Oddy
William Andrew Oddy, (born 6 January 1942) is a former Keeper of Conservation at the British Museum, notable for his publications on artefact conservation and numismatics, and for the development of the Oddy test. In 1996 he was awarded the Forbes Prize "for outstanding work in the field of conservation" by the International Institute for Conservation, and gave the attendant Forbes Lecture that year in Copenhagen. He retired in 2002 and was appointed as an Officer of the Order of the British Empire the same year. Early life William Andrew Oddy was born on 6 January 1942 in Bradford and spent his childhood in the nearby township of Baildon. He was the first son of William Tingle Oddy, then serving in the Auxiliary Fire Service for the duration of World War II, and Hilda Florence Oddy (née Dalby). He attended Sandal Primary School in Baildon and Bradford Grammar School. It was during these years that he developed an interest in archaeology after having visited the excavation ...

British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is among the largest and most comprehensive in existence. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections. The British Museum was the first public national museum to cover all fields of knowledge. The museum was established in 1753, largely b ...

Freedom Of The City
The Freedom of the City (or Borough in some parts of the UK) is an honour bestowed by a municipality upon a valued member of the community, or upon a visiting celebrity or dignitary. Arising from the medieval practice of granting respected citizens freedom from serfdom, the tradition still lives on in countries such as the United States, United Kingdom, Ireland, Australia, Canada, South Africa and New Zealand—although today the title of "freeman" confers no special privileges. The Freedom of the City can also be granted by municipal authorities to military units which have earned the city's trust; in this context, it is sometimes called the Freedom of Entry. This allows them the freedom to parade through the city, and is an affirmation of the bond between the regiment and the citizenry. The honour was sometimes accompanied by a "freedom box", a small gold box inscribed to record the occasion; these are not usual today. In some countries, such as the United States, esteemed ...

National Maritime Museum
The National Maritime Museum (NMM) is a maritime museum in Greenwich, London. It is part of Royal Museums Greenwich, a network of museums in the Maritime Greenwich World Heritage Site. Like other publicly funded national museums in the United Kingdom, it has no general admission charge; there are admission charges for most side-gallery temporary exhibitions, usually supplemented by many loaned works from other museums. Creation and official opening The museum was created by the National Maritime Museum Act 1934 under a Board of Trustees, appointed by HM Treasury. It is based on the generous donations of Sir James Caird (1864–1954). King George VI formally opened the museum on 27 April 1937 when his daughter Princess Elizabeth accompanied him for the journey along the Thames from London. The first director was Sir Geoffrey Callender. Collection Since the earliest times Greenwich has had associations with the sea and navigation. It was a landing place for the Romans, Henry ...

Kent
Kent is a county in South East England and one of the home counties. It borders Greater London to the north-west, Surrey to the west and East Sussex to the south-west, and Essex to the north across the estuary of the River Thames; it faces the French department of Pas-de-Calais across the Strait of Dover. The county town is Maidstone. It is the fifth most populous county in England, the most populous non-Metropolitan county and the most populous of the home counties. Kent was one of the first British territories to be settled by Germanic tribes, most notably the Jutes, following the withdrawal of the Romans. Canterbury Cathedral in Kent, the oldest cathedral in England, has been the seat of the Archbishops of Canterbury since the conversion of England to Christianity that began in the 6th century with Saint Augustine. Rochester Cathedral in Medway is England's second-oldest cathedral. Located between London and the Strait of Dover, which separates England from mainla ...

Graveney
Graveney is a relatively small but widely dispersed village located between Faversham and Whitstable in Kent, England. The main part of the village is located along the intersection of Seasalter Road, Sandbanks Road and Head Hill Road (at the railway crossing), which is surrounded by farmland. The rest of the village is dispersed amongst this farmland. Features include a local Pub ('The Four Horseshoes'), a primary school and a church. There is also a regular bus service that runs through the village. The Saxon Shore Way (long-distance path) passes around the Graveney Marshes (between Seasalter and Faversham). The marshes are part of the South Swale SSSI. History The first records of Graveney are as land acquired in 811 by Wilfred, archbishop of Canterbury, from Cenulph, King of Mercia. Graveney is listed in the Domesday Book in 1086 and was held by the de Gravene and de Feversham families and from 1408 by the Botiller family. Anne Botiller married John Martyn (d.1436) who bui ...

Diol
A diol is a chemical compound containing two hydroxyl groups ( groups). An aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol. Examples of diols in which the hydroxyl functional groups are more widely separated include 1,4-butanediol and propylene-1,3-diol, or beta propylene glycol, . Synthesis of classes of diols Geminal diols A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H2C(OH)2. Another example is (F3C)2C(OH)2, the hydrated form of hexafluoroacetone. Many gem-diols undergo further condensation to give dimeric and oligomeric derivatives. This reaction applies to glyoxal and related aldehydes. Vicinal diols In a vicinal diol, t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sepiolite
Sepiolite, also known in English by the German name meerschaum ( , ; ; meaning "sea foam"), is a soft white clay mineral, often used to make tobacco pipes (known as meerschaum pipes). A complex magnesium silicate, a typical chemical formula for which is Mg4Si6O15(OH)2·6H2O, it can be present in fibrous, fine-particulate, and solid forms. The fibrous clay minerals have recently been shown to exist as a continuous polysomatic series where the endmembers are sepiolite and palygorskite. There is a continuous variation in chemical composition from sepiolite, the most magnesic and trioctahedral endmember, to palygorskite, the least magnesic, most Al- Fe- bearing, dioctahedral endmember. Originally named ''meerschaum'' by Abraham Gottlob Werner in 1788, it was named ''sepiolite'' by Ernst Friedrich Glocker in 1847 for an occurrence in Bettolino, Baldissero Canavese, Torino Province, Piedmont, Italy. The name comes from Greek ''sepion'' (σήπιον), meaning "cuttlebone" (the poro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Niello
Niello is a black mixture, usually of sulphur, copper, silver, and lead, used as an inlay on engraved or etched metal, especially silver. It is added as a powder or paste, then fired until it melts or at least softens, and flows or is pushed into the engraved lines in the metal. It hardens and blackens when cool, and the niello on the flat surface is polished off to show the filled lines in black, contrasting with the polished metal (usually silver) around it. It may also be used with other metalworking techniques to cover larger areas, as seen in the sky in the diptych illustrated here. The metal where niello is to be placed is often roughened to provide a key. In many cases, especially in objects that have been buried underground, where the niello is now lost, the roughened surface indicates that it was once there. Statistical consideration Niello was used on a variety of objects including sword hilts, chalices, plates, horns, adornment for horses, jewellery such as bra ...

Metallurgical Assay
A metallurgical assay is a compositional analysis of an ore, metal, or alloy, usually performed in order to test for purity or quality. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals (bullion) are assayed by an assay office. Silver is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES). Precious metal items of art or jewelry are frequently hallmarked (depending upon the requirements of the laws of either the place of manufacture or the place of import). Where required to be hallmarked, semi-finished precious metal items of art or jewelry pass through the official testing channels where they are analyzed or assayed for precious metal content. While different nations permit a variety of legally acceptable finenesses, the assayer is actually testing to determine that the fineness of the product conforms with the statement or claim of fin ...

Sutton Hoo
Sutton Hoo is the site of two early medieval cemeteries dating from the 6th to 7th centuries near the English town of Woodbridge. Archaeologists have been excavating the area since 1938, when a previously undisturbed ship burial containing a wealth of Anglo-Saxon artefacts was discovered. The site is important in establishing the history of the Anglo-Saxon kingdom of East Anglia as well as illuminating the Anglo-Saxons during a period which lacks historical documentation. The site was first excavated by Basil Brown, a self-taught archaeologist, under the auspices of the landowner Edith Pretty, but when its importance became apparent, national experts took over. The artefacts the archaeologists found in the burial chamber include a suite of metalwork dress fittings in gold and gems, a ceremonial helmet, a shield and sword, a lyre, and silver plate from the Byzantine Empire. The ship burial has prompted comparisons with the world of ''Beowulf''. The Old English poem is partly s ...
