The Iron Bridge
The Iron Bridge is a cast iron arch bridge that crosses the River Severn in Shropshire, England. Opened in 1781, it was the first major bridge in the world to be made of cast iron. Its success inspired the widespread use of cast iron as a structural material, and today the bridge is celebrated as a symbol of the Industrial Revolution. The geography of the deep Ironbridge Gorge, formed by glacial action during the last ice age, meant that there are industrially useful deposits of coal, iron ore, limestone and fire clay present near the surface where they are readily mined, but also that it was difficult to build a bridge across the river at this location. To cope with the instability of the banks and the need to maintain a navigable channel in the river, a single span iron bridge was proposed by Thomas Farnolls Pritchard. After initial uncertainty about the use of iron, construction took place over two years, with Abraham Darby III responsible for the ironwork. The bridge cro ...

Iron is a chemical element; it has chemical symbol, symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 element, group 8 of the periodic table. It is, by mass, the abundance of the chemical elements#Earth, most common element on Earth, forming much of Earth's outer core, outer and inner core. It is the fourth most abundance of elements in Earth's crust, abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or Metallurgical furnace, furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelting, smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace list of copper alloys, copper alloys – in some regions, only around 1200 BC.

Fire Clay
Fire clay is a range of refractory clays used in the manufacture of ceramics, especially fire brick. The United States Environmental Protection Agency defines fire clay very generally as a "mineral aggregate composed of hydrous silicates of aluminium (Al2O3·2SiO2·2H2O) with or without free silica." Properties High-grade fire clays can withstand temperatures of 1,775 °C (3,227 °F), but to be referred to as a "fire clay" the material must withstand a minimum temperature of .Minerals Zone, World Mineral Exchange. Retrieved 2011-6-23. Fire clays range from '' flint clays'' to ''plastic fire clays'', but there are ''semi-flint'' and ''semi-plastic'' fire clays as well.

Broseley
Broseley () is a market town in Shropshire, England, with a population of 4,929 at the 2011 Census and an estimate of 5,022 in 2019. The River Severn flows to its north and east. The first iron bridge in the world was built in 1779 across the Severn, linking Broseley with Coalbrookdale and Madeley. This contributed to the early industrial development in the Ironbridge Gorge, which is now part of a World Heritage Site. History There was a settlement existing in 1086, listed as Bosle in the Domesday Book of that year, when it lay in the Hundred of Alnodestreu. That jurisdiction was dismembered in the time of King Henry I, when Broseley and Willey were reassigned to the Munslow Hundred. Finally they were transferred to the Liberty of Wenlock on its creation in the time of King Richard I. The place name appears as ''Burewardeslega'' in 1177, and in similar variants thereafter, indicating that it had anciently been Burgheard's (or Burgweard's) clearing, or grove. In Broseley ...

Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or petroleum in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude petroleum in oil refinery, petroleum refineries. Coke may also be formed naturally by geology, geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. It is the residue of a destructive distillation process. Production Industrial coke furnaces The industrial production of coke from coal is called coking. The coal is baked in an airless k ...

Abraham Darby I
Abraham Darby, in his later life called Abraham Darby the Elder, now sometimes known for convenience as Abraham Darby I (14 April 1677 – 5 May 1717, the first and best known of Abraham Darby (other), several men of that name), was a British ironmaster and foundryman. Born into an Kingdom of England, English Quaker family that played an important role in the Industrial Revolution, Darby developed a method of producing pig iron in a blast furnace fuelled by Coke (fuel), coke rather than charcoal. This was a major step forward in the production of iron as a raw material for the Industrial Revolution. Early life Abraham Darby was the son of John Darby, a yeoman farmer and locksmith by trade, and his wife Ann Baylies. He was born at Wren's Nest in Woodsetton, Dudley, Woodsetton, Staffordshire, now part of Dudley, West Midlands (county), West Midlands. He was descended from nobility; his great-grandmother Jane was an illegitimate child of Edward Sutton, 5th Baron Dudle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Lapworth
Lake Lapworth was a postulated glacial lake in Great Britain, believed to have formed during the last ice age when glaciers ended the northern outlet of the Severn. This ran through the Dee (which passes by Chester). At some point or points it ran into glaciers and backed up to form a resultant lake. This overflowed southwards cutting the Ironbridge Gorge, near Telford in Shropshire. This permanently diverted most of the Severn drainage basin to its current basin which flows south. Etymology The lake was named in 1924 by Leonard Johnston Wills for the late Charles Lapworth ( 1920), who suggested its existence in 1898. Frederic William Harmer (1835-1923) proposed the same causation and timing in 1907 having considered glacial lake sediments found on the Shropshire Plain. Geography and geology Lake Lapworth is one of several glacial lakes that are thought to have existed during the Ice Age in the late Pleistocene. This was the geological epoch that lasted from about 2,580,000 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
