Baptist Mills, Bristol
Baptist Mills an area of the city of Bristol, England. The name derives from the former mills which stood in that area. Geology The solid geology of Baptist Mills comprises Triassic Redcliffe Sandstone, which is overlain by superficial deposits of Quaternary alluvium in the floodplain of the Horfield Brook and the River Frome. History Baptist Mills is so named from the mills that once stood there. A grist (flour) mill is recorded in this area in a document written in 1470, and again in 1610, when they are marked on Chester and Master's Map of Kingswood. The mills were converted to brass mills by the Bristol Brass Company, formed in 1702 by Abraham Darby, Edward lloyd, John Andrews, and Arthur Thomas. In 1706, further partners were admitted, the business becoming an early unincorporated joint stock company with a capital of £8000. While there, Darby recruited skilled 'Dutchmen' to operate a brass battery with trip hammers. He may also have recruited men skilled in sand moul ...

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a Venetia ...

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Frome, Bristol
The Frome , historically the Froom, is a river that rises in Dodington Park, South Gloucestershire, and flows southwesterly through Bristol to join the river Avon. It is approximately long, and the mean flow at Frenchay is . The name ''Frome'' is shared with several other rivers in South West England and means 'fair, fine, brisk'. The river is known locally in east Bristol as the ''Danny''. As with many urban rivers, the Frome has suffered from pollution, but several stretches run through parks and reserves that sustain a range of wildlife. The river's power was harnessed by many watermills, and the river mouth area was developed as shipyards by the eighteenth century. As the city of Bristol developed in the nineteenth and twentieth centuries, flooding became a major problem, remedied by the construction of storm drains and diversions. Etymology The river's name derives from the British Celtic, meaning 'fair, fine, brisk’. It is not to be confused with other rivers in the ...

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 several men of that name), was an English ironmaster and foundryman. Born into an 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 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, Staffordshire, now part of Dudley, West Midlands. He was descended from nobility; his great-grandmother Jane was an illegitimate child of Edward Sutton, 5th Baron Dudley. Abraham's great-grandmother was a sister of the whole blood to Dud Dudley, who claimed to have smelted i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joint Stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In t ...

Molding (process)
Molding (American English) or moulding (British and Commonwealth English; see spelling differences) is the process of manufacturing by shaping liquid or pliable raw material using a rigid frame called a mold or matrix. This itself may have been made using a pattern or model of the final object. A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object. Articulated molds have multiple pieces that come together to form the complete mold, and then disassemble to release the finished casting; they are expensive, but necessary when the casting shape has complex overhangs. Piece-molding uses a number of different molds, each creating a section of a complicated object. This is generally only used for larger a ...

Foundry
A foundry is a factory that produces metal castings. Metals are cast into shapes by melting them into a liquid, pouring the metal into a mold, and removing the mold material after the metal has solidified as it cools. The most common metals processed are aluminum and cast iron. However, other metals, such as bronze, brass, steel, magnesium, and zinc, are also used to produce castings in foundries. In this process, parts of desired shapes and sizes can be formed. Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling. Process In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified pa ...

Coalbrookdale
Coalbrookdale is a village in the Ironbridge Gorge in Shropshire, England, containing a settlement of great significance in the history of iron ore smelting. It lies within the civil parish called the Gorge. This is where iron ore was first smelted by Abraham Darby using easily mined "coking coal". The coal was drawn from drift mines in the sides of the valley. As it contained far fewer impurities than normal coal, the iron it produced was of a superior quality. Along with many other industrial developments that were going on in other parts of the country, this discovery was a major factor in the growing industrialisation of Britain, which was to become known as the Industrial Revolution. Today, Coalbrookdale is home to the Ironbridge Institute, a partnership between the University of Birmingham and the Ironbridge Gorge Museum Trust offering postgraduate and professional development courses in heritage.

Rockingham Teapots
A Brown Betty is a type of teapot, round and with a manganese brown glaze known as Rockingham glaze. The original teapots came from a red clay that was discovered in the Stoke-on-Trent area of Britain, in 1695. This clay resulted in a ceramic which seemed to retain heat better and so found use as the material for the teapot as early as the seventeenth century. These early pots were tall and shaped more like coffee pots. In the nineteenth century the pots began to take on the more rounded shape of the modern Brown Betty. The Rockingham Glaze was brushed on the pot and allowed to run down the sides, creating a streaky finish as it was fired. In the Victorian era, when tea was at its peak of popularity, tea brewed in the Brown Betty was considered excellent. This was attributed to the design of the pot which allowed the tea leaves more freedom to swirl around as the water was poured into the pot, releasing more flavour with less bitterness.
