Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Mining In Wales
Mining in Wales provided a significant source of income to the economy of Wales throughout the nineteenth century and early twentieth century. It was key to the Industrial Revolution. Wales was famous for its coal mining, in the Rhondda Valley, the South Wales Valleys and throughout the South Wales coalfield and by 1913 Barry had become the largest coal exporting port in the world, with Cardiff as second, as coal was transported down by rail. Northeast Wales also had its own coalfield and Tower Colliery (closed January 2008) near Hirwaun is regarded by many as the oldest open coal mine and one of the largest in the world. Wales has also had a significant history of mining for slate, gold and various metal ores. History There had been small-scale mining in Wales in the pre-Roman British Iron Age, but it would be undertaken on an industrial scale under the Romans, who completed their conquest of Wales in AD 78. Substantial quantities of gold, copper, and lead were extracted, al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Powys
Powys (; ) is a county and preserved county in Wales. It is named after the Kingdom of Powys which was a Welsh successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. Geography Powys covers the historic counties of Montgomeryshire and Radnorshire, most of Brecknockshire, and part of historic Denbighshire. With an area of about , it is now the largest administrative area in Wales by land and area (Dyfed was until 1996 before several former counties created by the Local Government Act 1972 were abolished). It is bounded to the north by Gwynedd, Denbighshire and Wrexham County Borough; to the west by Ceredigion and Carmarthenshire; to the east by Shropshire and Herefordshire; and to the south by Rhondda Cynon Taf, Merthyr Tydfil County Borough, Caerphilly County Borough, Blaenau Gwent, Monmouthshire and Neath Port Talbot.

Wales
Wales ( cy, Cymru ) is a country that is part of the United Kingdom. It is bordered by England to the east, the Irish Sea to the north and west, the Celtic Sea to the south west and the Bristol Channel to the south. It had a population in 2021 of 3,107,500 and has a total area of . Wales has over of coastline and is largely mountainous with its higher peaks in the north and central areas, including Snowdon (), its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate. The capital and largest city is Cardiff. Welsh national identity emerged among the Celtic Britons after the Roman withdrawal from Britain in the 5th century, and Wales was formed as a kingdom under Gruffydd ap Llywelyn in 1055. Wales is regarded as one of the Celtic nations. The conquest of Wales by Edward I of England was completed by 1283, though Owain Glyndŵr led the Welsh Revolt against English rule in the early 15th century, and briefly re-establis ...

Afon Clywedog
The Afon Clywedog is an upland headwater tributary of the River Severn in Powys, Wales. It is approximately 29 km long and has its source on the flanks of Plynlimon and has its confluence with the Severn in Llanidloes. The annual rainfall over the catchment is between 1737 mm and 1836 mm. River regulation A large part of the upper catchment of the river is inundated by the Clywedog reservoir which stores water from the catchment, especially during the winter months, and releases it during periods of low flow to support the flow in the Severn so that drinking water may be abstracted downstream. The management rules also enable the reservoir to maintain the reservoir below maximum level during the winter so that there is capacity to absorb flood flows to reduce the impact of flooding further down the main river. The Afon Clywedog thus has a highly regulated flow with relatively high flow in dry conditions and reduced flow in wetter weather. See also * Bryntail ...

Clywedog Reservoir
The Clywedog Reservoir ( cy, Llyn Clywedog) is a reservoir near Llanidloes, Wales on the head-waters of the River Severn. The construction of the reservoir was enabled by an Act of Parliament which asserted that ''"At certain times the flow of water in the river is inadequate ... unless that flow were regulated so as to ensure that at those times water in addition to the natural flow will flow down the river."'' Purpose Its primary purpose was to regulate the flow in the River Severn to mitigate flooding and provide support for drinking water abstractions for the West Midlands. It was completed in 1967 and is situated near the B4518 road north of Llanidloes, Powys. It regulates the flow of water in the River Severn by releasing water into the river channel during low flow periods and re-filling during the wetter winter months. This enables major water abstractions to be made from the River Severn to supply the West Midlands with of drinking water. Capacity is held in t ...

Baryte
Baryte, barite or barytes ( or ) is a mineral consisting of barium sulfate ( Ba S O4). Baryte is generally white or colorless, and is the main source of the element barium. The ''baryte group'' consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid solution (Ba,Sr)SO4. Names and history The radiating form, sometimes referred to as ''Bologna Stone'', attained some notoriety among alchemists for specimens found in the 17th century near Bologna by Vincenzo Casciarolo. These became phosphorescent upon being calcined. Carl Scheele determined that baryte contained a new element in 1774, but could not isolate barium, only barium oxide. Johan Gottlieb Gahn also isolated barium oxide two years later in similar studies. Barium was first isolated by electrolysis of molten barium salts in 1808 by Sir Humphry Davy in England.

Forge
A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by forging, or to the point at which work hardening no longer occurs. The metal (known as the "workpiece") is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge. Types Coal/coke/charcoal forge A forge typically uses bituminous coal, ind ...
