Bersham Ironworks
Bersham Ironworks were large ironworks at Bersham, near Wrexham, Wales. They are most famous for being the original working site of John Wilkinson. They were also the first site in the world to use a new way of boring holes in cannon and steam engine cylinders. History Ironworking began at Bersham around 1640, and evidence shows that the cannon for the Royalists in the English Civil War were made there. In the 18th century, Isaac Wilkinson bought the ironworks and ran it for a considerable number of years. The main product was cannon, although the process to make them in iron was difficult, and cannonballs often became stuck in the barrel, leading to explosions. When Isaac's son John Wilkinson took over, he employed a boring machine to accurately make a smooth bore cannon, which became so popular that cannons produced using this technique were used in the American War of Independence and the Napoleonic wars. As well as cannon, the smooth bore machine could make cylinders for B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brymbo
Brymbo is a village and Community (Wales), community in Wrexham County Borough, Wales. It lies in the hilly country to the west of Wrexham city, largely surrounded by farmland. At the United Kingdom Census 2001, 2001 Census, the population of the community area (including Brymbo village, along with the villages of Tanyfron and Bwlchgwyn and a number of rural hamlets) was 3,482, increasing to 4,836 at the 2011 Census.

Former Buildings And Structures In Wrexham County Borough
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Ironworks And Steelworks In Wales
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 ...

Welsh Government
The Welsh Government ( cy, Llywodraeth Cymru) is the Welsh devolution, devolved government of Wales. The government consists of ministers and Minister (government), deputy ministers, and also of a Counsel General for Wales, counsel general. Ministers only attend the Cabinet Meetings of the Welsh Government. It is led by the First Minister of Wales, first minister, usually the leader of the largest party in the Senedd (Welsh Parliament; ), who selects ministers and deputy ministers with the approval of the Senedd. The government is responsible for Table (parliamentary procedure), tabling policy in List of devolved matters in Wales, devolved areas (such as health, education, economic development, transport and local government) for consideration by the Senedd and implementing policy that has been approved by it. The current Welsh Government is a Second Drakeford government, Labour minority administration, following the 2021 Senedd election. Mark Drakeford has been the first minister ...

Minera Limeworks
The Minera Limeworks were extensive lime quarries and kilns at Minera in Wrexham, Wales. It was located at , near the villages of Gwynfryn, Minera, and Coedpoeth and was locally referred to as ''The Calch''. History The Minera Limeworks were once the largest lime workings in the north of Wales. Limeburning at Minera is recorded from as early as 1620 but the Minera Lime Company was established in 1852. The total output from the Minera area quarries was estimated, in 1859, to be around 300,000 tons, with 200,000 tons of this converted to lime. The Minera Lime Company became a limited company in 1865, and this prompted some heavy cash injection into the works. Using this money, the company erected a "Hoffmann kiln". Originally destined for brickmaking, it was soon converted to limeburning. This kiln still exists and is one of three that were purpose-built for lime burning left in the UK: another is located at Langcliffe in Yorkshire, another is located at Llanymynech Limew ...

Waggonway
Wagonways (also spelt Waggonways), also known as horse-drawn railways and horse-drawn railroad consisted of the horses, equipment and tracks used for hauling wagons, which preceded steam-powered railways. The terms plateway, tramway, dramway, were used. The advantage of wagonways was that far bigger loads could be transported with the same power. Ancient systems The earliest evidence is of the 6 to 8.5 km long ''Diolkos'' paved trackway, which transported boats across the Isthmus of Corinth in Greece from around 600 BC. Wheeled vehicles pulled by men and animals ran in grooves in limestone, which provided the track element, preventing the wagons from leaving the intended route. The Diolkos was in use for over 650 years, until at least the 1st century AD. Paved trackways were later built in Roman Egypt. Wooden rails Such an operation was illustrated in Germany in 1556 by Georgius Agricola (image right) in his work De re metallica. This line used "Hund" carts wit ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Pig Iron
Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it brittle and not useful directly as a material except for limited applications. The traditional shape of the molds used for pig iron ingots is a branching structure formed in sand, with many individual ingots at right angles to a central channel or "runner", resembling a litter of piglets being nursed by a sow. When the metal had cooled and hardened, the smaller ingots (the "pigs") were simply broken from the runner (the "sow"), hence the name "pig iron". As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand cause only insignificant problems considering the ease of casting and handling them.

River Clywedog
The River Clywedog is a river in Wrexham County Borough, Wales. Its uses have been watering crops, powering industrial machinery but is now used as walking trails or geography trips. The river originates to the west of Wrexham, and joins the River Dee some four miles south east of the city. Course of the river The river Clywedog rises in the hills west of the village of Minera. After flowing through Minera it turns south-east, past Coedpoeth, Bersham and Rhostyllen and through the Erddig Country Park, then east, passing slightly to the south of Wrexham. There is a path along the entire river bank from Minera to Wrexham. After passing the Wrexham industrial estate, the river joins the River Dee near the English/Welsh border. History During the 18th and early 19th centuries there were 17 watermills along the river: fulling mills for preparing cloth, mills for grinding corn and malt, and paper mills. Large waterwheels powered the bellows blasting air into the iron furnaces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lime Kiln
A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime (material), lime called quicklime (calcium oxide). The chemical equation for this chemical reaction, reaction is :Calcium carbonate, CaCO3 + heat → Calcium oxide, CaO + Carbon dioxide, CO2 This reaction can take place at anywhere above 840 °C (1544 °F), but is generally considered to occur at 900 °C(1655 °F) (at which temperature the partial pressure of CO2 is 1 atmosphere (unit), atmosphere), but a temperature around 1000 °C (1832 °F) (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly.Parkes, G.D. and Mellor, J.W. (1939). ''Mellor's Modern Inorganic Chemistry'' London: Longmans, Green and Co. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime (calcium hydroxide) can be formed by mixing quicklime with water. Early li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
