Stone Mould
Within the history of metalworking, medieval stone moulds are well represented in the Herbert Art Gallery & Museum in Coventry with over 169 examples. The Molding (process), moulds from Coventry are from a highly calcareous mudstone of Jurassic type. Such stone comes from Southam, Long Itchington and Harbury, all less than 15 miles from Coventry. There must have been a well organised trade in raw material, production and export sales of the finished product but despite this no documentary evidence has been preserved of the industry. The trade must be between user and supplier directly. Excavations at Bayley Lane in 1988 produced 69 stone moulds so must have been one of the production centres in Coventry. Some moulds were used as a one use mould for objects made from precious metals for an elite clientele, but most were for more mundane objects such as belt buckles and were used until they were broken or cracked. Moulds changed along with fashion which allows them to be dated quite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metalworking
Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry. The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to highly technical modern processes such as machining and welding. It has been used as an industry, a driver of trade, individual hobbies, and in the creation of art; it can be regarded as both a science and a craft. Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cutting, or joining processes. Mo ...

Herbert Art Gallery & Museum
Herbert Art Gallery & Museum (also known as the Herbert) is a museum, art gallery, records archive, learning centre, media studio and creative arts facility on Jordan Well, Coventry, England. Overview The museum is named after Sir Alfred Herbert, a Coventry industrialist and philanthropist whose gifts enabled the original building to be opened in 1960. Building began in 1939, with an interruption by the Second World War, and the Herbert opened in 1960. In 2008, it reopened after a £14 million refurbishment. The Herbert is run by Culture Coventry, a registered charity, and admission is free. It derives financial support from donations, sales at the museum shop, and hiring the buildings out. In 2010, the museum and gallery received more than 300,000 visitors, making it one of the most popular free tourist attractions in the West Midlands.

Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southam
Southam () is a market town and civil parish in the Stratford-on-Avon district of Warwickshire, England. Southam is situated on the River Stowe (called 'The Brook' by many locals), which flows from Napton-on-the-Hill and joins Warwickshire's River Itchen at Stoneythorpe, just outside the town. In the 2021 census, the population of Southam was 8,114, increased from 6,567 in 2011. History Southam was a Royal manor until AD 998, when Ethelred the Unready granted it to Earl Leofwine. When Coventry Priory was founded in 1043, Leofwine's son Leofric, Earl of Mercia granted Southam to it. The Domesday Book records the manor as "''Sucham''". The Priory, which in the 12th century became the first Coventry Cathedral, kept Southam until the 16th century when it surrendered all its estates to the Crown in the Dissolution of the Monasteries. Southam developed at the intersection of several roads: the main road between Coventry and Oxford (now the A423 road), the main road from Wa ...

Casting (metalworking)
In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled, and the metal part (the ''casting'') is extracted. Casting is most often used for making complex shapes that would be difficult or uneconomical to make by other methods. Casting processes have been known for thousands of years, and have been widely used for sculpture (especially in bronze), jewelry in precious metals, and weapons and tools. Highly engineered castings are found in 90 percent of durable goods, including cars, trucks, aerospace, trains, mining and construction equipment, oil wells, appliances, pipes, hydrants, wind turbines, nuclear plants, medical devices, defense products, toys, and more. Traditional techniques include lost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
