Stack Square
Blaenavon Ironworks is a former industrial site which is now a museum in Blaenavon, Wales. The ironworks was of crucial importance in the development of the ability to use cheap, low quality, high sulphur iron ores worldwide. It was the site of the experiments by Sidney Gilchrist Thomas and his cousin Percy Gilchrist that led to "the basic steel process" or "Gilchrist–Thomas process". The ironworks is on the outskirts of Blaenavon, in the borough of Torfaen, within the Blaenavon Industrial Landscape, a World Heritage Site. The site is under the care of Cadw, the Welsh Government's historic environment service. History of the works Early history Evidence of ironworking in the South Wales Valleys dates from the Roman period. In the 17th century, the Hanburys of Pontypool undertook tinplate manufacture in the area around Blaenavon. The land was the property of Lord Abergavenny, known as Lord Abergavenny's Hills, and in 1788 Henry Nevill, 2nd Earl of Abergavenny granted a r ...

Ironworks
An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ''ironworks'' is ''ironworks''. Ironworks succeeded bloomeries when blast furnaces replaced former methods. An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces or a foundry with or without other kinds of ironworks. After the invention of the Bessemer process, converters became widespread, and the appellation steelworks replaced ironworks. The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words ''sideros'' - iron and ''ergon'' or ''ergos'' - work. This is an unusual term in English, and it is best regarded as an anglicisation of a term used in French, Spanish, and other Romance languages. Historically, it is common ...

James Ashwell
James Ashwell (1799-1881) was an engineer and director, working in the coal, iron, and railway industries. In 1836 he helped in the formation of the Blaenavon Iron and Coal Company and was appointed resident managing director. Early life James Ashwell was born in 1799 in Nottingham. He attended Nottingham Grammar School and later Edinburgh University. As a school boy he showed an interest in his father's businesses in iron and coal. A visit to Manchester and Leeds in 1816, where he was fascinated by steam mills and machinery, particularly steam locomotives, led to his decision to be an engineer. Training He trained as an engineer with Bryan Donkin, and became friends with Henry Robinson Palmer, who was often employed by Thomas Telford to make surveys. Ashwell assisted Palmer on surveys in East Anglia. While still training he was involved in starting what is now the Institution of Civil Engineers. Work After completing his training Ashwell worked at ironworks in Derbyshire an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Kennard
Robert William Kennard JP DL (1800–1870) was a London-born merchant, financier, entrepreneur, JP and later Member of Parliament. The son of jeweller turn banker John Kennard ( Heywood, Kennards & Co, merged into Consolidated Bank Ltd), and Harriet Elizabeth Peirse, he trained as a merchant in London. Having invested in the Falkirk Iron Company in 1830, Kennard's consortia formed the Blaenavon Coal and Iron Company in 1836, which subsequently bought the Blaenavon Ironworks. There he employed his son, the noted civil engineer Thomas Kennard, and his cousin and the later photographer George Swan Nottage. Through his connections with the iron and steel industries, and access to large sums of money through his families banking connections, he became a significant financier during the railway boom of the 1830s, and also financed some of the government requirements during the Crimea War. Leveraging this, Kennard made his fortune as a director of several UK railway companies, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotch Cattle
Scotch Cattle was the name taken by bands of coal miners in 19th century South Wales, analogous to the Molly Maguires in Pennsylvania, who, in disguise, would visit the homes of other local miners who were working during a strike or cooperating with employers against the local mining community in other ways and punish them by ransacking their property or attacking them physically. They were featured in Alexander Cordell's book, set in this era, ''Rape of the Fair Country'' against a backdrop of the Newport Rising of 1839, Chartism and militancy in the South Wales Valleys of the mid 19th century. Some members of these bands were probably idealists, but some also were merely looking for a chance to loot property from the groups' targets—or even, in some cases, from bystanders. Such groups may have been active as early as 1808, although their activity cannot be confirmed before 1822; the last confirmable reference to a Scotch Cattle raid dates from 1850. As late as 1926, however, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cwmavon, Torfaen
Cwmavon (Welsh spelling: Cwmafon; translation: "river valley") is a hamlet about 2 miles south of Blaenavon and 4 miles north of Pontypool. The hamlet is part of the community of Abersychan in the county borough of Torfaen in south east Wales, and is within the boundaries of the historic county of Monmouthshire. Cwmavon is in the south of the Blaenavon Industrial Landscape (a World Heritage Site), the Blaenavon Landscape of Outstanding Historic Interest, and in the Cwmavon Conservation Area. Geography The scattered settlement lies in the steep wooded valley of the Afon Llwyd. The agricultural landscape, with irregular field patterns, scattered farmsteads, woodlands, sheep folds, limestone quarries and kilns is typical of the medieval and post-medieval mixed agriculture in the wider region. The Afon Llwyd is at the eastern edge of the South Wales coalfield, so no coal mining took place in Cwmavon. However, the western side of the valley, in areas such as Varteg and Garndiffa ...

Merthyr Tydfil
Merthyr Tydfil (; cy, Merthyr Tudful ) is the main town in Merthyr Tydfil County Borough, Wales, administered by Merthyr Tydfil County Borough Council. It is about north of Cardiff. Often called just Merthyr, it is said to be named after Tydfil, daughter of Brychan Brycheiniog, King Brychan of Brycheiniog, who according to legend was slain at Merthyr by pagans about 480 CE. generally means "Martyr of the Faith, martyr" in modern Welsh, but here closer to the Latin : a place of worship built over a martyr's relics. Similar place names in south Wales are Merthyr Cynog, Merthyr Dyfan and Merthyr Mawr. History Pre-history Peoples migrating north from Europe had lived in the area for many thousands of years. The archaeological record starts from about 1000 BC with the Celts. From their language, the Welsh language developed. Hillforts were built during the British Iron Age, Iron Age and the tribe that inhabited them in the south of Wales was called the Silures, according to Tacitu ...

Cyfarthfa Ironworks
The Cyfarthfa Ironworks were major 18th- and 19th-century ironworks in Cyfarthfa, on the north-western edge of Merthyr Tydfil, in South West Wales. The beginning The Cyfarthfa works were begun in 1765 by Anthony Bacon (by then a merchant in London), who in that year with William Brownrigg, a fellow native of Whitehaven, Cumberland, leased the right to mine in a tract of land on the west side of the river Taff at Merthyr Tydfil. They employed Brownrigg's brother-in-law Charles Wood to build a forge there, to use the potting and stamping process, for which he and his brother had a patent. This was powered by water from the river, the race dividing into six to power a clay mill (for making the pots), two stampers, two helve hammers and a chafery. The construction of the first coke blast furnace began in August 1766. This was intended to be 50 feet high with cast iron blowing cylinders, rather than the traditional bellows. It was probably brought into blast in autumn 1767. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Coxe (historian)
William Coxe (8 June 1828) was an English historian and priest who served as a travelling companion and tutor to nobility from 1771 to 1786. He wrote numerous historical works and travel chronicles. Ordained a deacon in 1771, he served as a rector and then archdeacon of Bemerton near Salisbury from 1786 until his death. Biography William Coxe was born on in Dover Street, Piccadilly, London, the eldest son of William Coxe (c. 17101760), a physician to the king's household, and his wife, Martha, daughter of Paul D'Aranda. He was the older brother of the writer and poet Peter Coxe (c. 1753–1844), who wrote the poem "Social Day". Following his father's death in 1760, his mother married John Christopher Smith, who was Handel's amanuensis. Educated at Marylebone Grammar School (1753–54) and then at Eton College (1754–64), Coxe matriculated to King's College, Cambridge at Easter 1765. He received his BA in 1769, and his MA in 1772. From 1768 to 1771, he was a fellow of Kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Outcrop
An outcrop or rocky outcrop is a visible exposure of bedrock or ancient superficial deposits on the surface of the Earth. Features Outcrops do not cover the majority of the Earth's land surface because in most places the bedrock or superficial deposits are covered by soil and vegetation and cannot be seen or examined closely. However, in places where the overlying cover is removed through erosion or tectonic uplift, the rock may be exposed, or ''crop out''. Such exposure will happen most frequently in areas where erosion is rapid and exceeds the weathering rate such as on steep hillsides, mountain ridges and tops, river banks, and tectonically active areas. In Finland, glacial erosion during the last glacial maximum (ca. 11000 BC), followed by scouring by sea waves, followed by isostatic uplift has produced many smooth coastal and littoral outcrops. Bedrock and superficial deposits may also be exposed at the Earth's surface due to human excavations such as quarrying and build ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
