Pontneathvaughan
Pontneddfechan, also known as Pontneathvaughan (pronounced ) ("bridge over the Little Neath" in Welsh) is the southernmost village in the county of Brecknockshire, Wales, within the Vale of Neath, in the community of Ystradfellte and in the principal area of Powys. It stands at the confluence of the rivers Mellte and Nedd Fechan ("Neath Vaughan") and gives access to a series of waterfalls that adorn the upper Neath valley. Dinas Rock is a quarried limestone promontory east of the village, popular with visitors. History District industrial activities started with a 21-year lease of an area from the Marquess of Bute by the Quaker entrepreneur William Weston Young, for mining silica rock round Craig-y-Ddinas from 1822 onwards. The silica was extracted for firebricks at the ''Dinas Firebrick Co.'' in Pont Walby. In 1843, Young's lease ran out and the then ''Riddles, Young & Co.'' firebrick makers moved to new premises on The Green, Neath. The stone sleepers for the silica mine tramw ...

John Crichton-Stuart, 2nd Marquess Of Bute
John Crichton-Stuart, 2nd Marquess of Bute, KT, FRS (10 August 1793 – 18 March 1848), styled Lord Mount Stuart between 1794 and 1814, was a wealthy aristocrat and industrialist in Georgian and early Victorian Britain. He developed the coal and iron industries across South Wales and built the Cardiff Docks. Bute's father, John, Lord Mount Stuart, died a few months after he was born and as a young child he was brought up first by his mother, the former Lady Elizabeth McDougall-Crichton, and later by his paternal grandfather, John Stuart, 1st Marquess of Bute. He travelled widely across Europe before attending Cambridge University. He contracted an eye condition and remained partially sighted for the rest of his life. Having inherited large estates across Britain, he married his first wife, Lady Maria North, in 1818, and together they lived a relatively secluded life in Mount Stuart House in Scotland, one of Bute's four seats. Bute was dour but industrious, with a flair for ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Imperial Chemical Industries
Imperial Chemical Industries (ICI) was a British chemical company. It was, for much of its history, the largest manufacturer in Britain. It was formed by the merger of four leading British chemical companies in 1926. Its headquarters were at Millbank in London. ICI was a constituent of the FT 30 and later the FTSE 100 indices. ICI made general chemicals, plastics, paints, pharmaceuticals and speciality products, including food ingredients, speciality polymers, electronic materials, fragrances and flavourings. In 2008, it was acquired by AkzoNobel, which immediately sold parts of ICI to Henkel and integrated ICI's remaining operations within its existing organisation. History Development of the business (1926–1944) The company was founded in December 1926 from the merger of four companies: Brunner Mond, Nobel Explosives, the United Alkali Company, and British Dyestuffs Corporation. It established its head office at Millbank in London in 1928. Competing with DuPont a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nobel Industries (Scotland)
Nobel Enterprises () is a chemicals business that used to be based at Ardeer, in the Ayrshire town of Stevenston, in Scotland. Specialising in nitrogen-based propellants and explosives and nitrocellulose-based products such as varnishes and inks. It was formerly ICI Nobel, a division of the chemicals group ICI, but was then sold to Inabata, a Japanese trading firm. The business was sold on to Chemring Group in 2005 and is now a Scottish Company (Chemring Energetics UK Ltd), part of Chemring Group. History Nobel Industries Limited was founded in 1870 by Swedish chemist and industrialist Alfred Nobel for the production of the new explosive dynamite in the United Kingdom. The factory was overseen and run by George McRoberts. McRoberts and John Downie raised the £24,000 needed to found the company rather than Nobel himself. It was chaired by the Glasgow shipbuilder, Charles Randolph (1809-1878). Ardeer, on the coast at Ayrshire, was chosen for the company's first factory. ...

Saltpetre
Potassium nitrate is a chemical compound with the chemical formula . This alkali metal nitrate salt is also known as Indian saltpetre (large deposits of which were historically mined in India). It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or ''nitre'' in the UK). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or ''saltpetre'' in the UK). Major uses of potassium nitrate are in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (black powder). In processed meats, potassium nitrate reacts with hemoglobin and myoglobin generating a red color. Etymology Potassium nitrate, because of its early and global use and production, has many names. Hebrew and Egyptian words for it had the consonants n-t- ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sulphur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellan ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Firebrick
A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency. Usually dense firebricks are used in applications with extreme mechanical, chemical, or thermal stresses, such as the inside of a wood-fired kiln or a furnace, which is subject to abrasion from wood, fluxing from ash or slag, and high temperatures. In other, less harsh situations, such as in an electric- or natural gas-fired kiln, more porous bricks, commonly known as "kiln bricks", are a better choice. They are weaker, but they are much lighter and easier to form and insulate far better than dense bricks. In any case, firebricks should not spall, and their strength should hold up well during rapid temperature changes. Manufacture In the making of firebrick, fireclay is fired in the kiln until it is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Silica
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula , most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand. Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as a synthetic product. Notable examples include fused quartz, fumed silica, silica gel, opal and aerogels. It is used in structural materials, microelectronics (as an Insulator (electricity), electrical insulator), and as components in the food and pharmaceutical industries. Structure In the majority of silicates, the silicon atom shows tetrahedral coordination geometry, tetrahedral coordination, with four oxygen atoms surrounding a central Si atomsee 3-D Unit Cell. Thus, SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms. In contrast, CO2 is a linear ...
