Coppersmiths
A coppersmith, also known as a brazier, is a person who makes artifacts from copper and brass. Brass is an alloy of copper and zinc. The term "redsmith" is used for a tinsmith that uses tinsmithing tools and techniques to make copper items. History Anthropologists believe copper to be the first metal used by humans due to its softness and ease of manipulation. In antiquity, copper's durability and resistance to rust or corrosion proved valuable. Copper's relationship with man is thought to date back over six thousand years. Coppersmith is one of the few trades that have a mention in the Bible. Copper was particularly worked in England, with ores smelted in Wales as early as the 1500s. Copper was found in great quantities in North America, especially Montana, as well as archaic copper mines near Lake Superior, which was recorded by a Jesuit missionary in 1659. Coppersmithing as a trade benefited strongly from the invention of sheet metal Sheet metal is metal formed into t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sal Ammoniac
Salammoniac, also sal ammoniac or salmiac, is a rare naturally occurring mineral composed of ammonium chloride, NH4Cl. It forms colorless, white, or yellow-brown crystals in the isometric-hexoctahedral class. It has very poor cleavage and is brittle to conchoidal fracture. It is quite soft, with a Mohs hardness of 1.5 to 2, and it has a low specific gravity of 1.5. It is water-soluble. Sal ammoniac is also the archaic name for the chemical compound ammonium chloride. Pliny, in Book XXXI of his '' Natural History'', refers to a salt produced in the Roman province of Cyrenaica named ''hammoniacum'', so called because of its proximity to the nearby Temple of Jupiter Amun (Greek Ἄμμων ''Ammon''). However, the description Pliny gives of the salt does not conform to the properties of ammonium chloride. According to Herbert Hoover's commentary in his English translation of Georgius Agricola's '' De re metallica'', it is likely to have been common sea salt. In any case, tha ...

Keswick School Of Industrial Art
Keswick School of Industrial Art (KSIA) was founded in 1884 by Canon Hardwicke Rawnsley and his wife Edith as an evening class in woodwork and Repoussé and chasing, repoussé metalwork at the Crosthwaite Parish Rooms, in Keswick, Cumbria.Bott, p. 117 The enterprise, designed to alleviate unemployment, prospered, and within ten years more than a hundred men were attending classes. A new building was erected for the school at a nearby site. The school closed in 1984 and the building became a restaurant. History Rawnsley was the vicar of Crosthwaite Parish Church, Crosthwaite, at the edge of Keswick, from 1883 to 1917. He was one of the three co-founders of the National Trust for Places of Historic Interest or Natural Beauty, National Trust and was a prominent figure in philanthropic enterprises in the area, helping to establish a grammar school, a hospital and a farm school. Inspired by the precepts of John Ruskin, Rawnsley and his wife set up free evening classes in the parish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornwall
Cornwall (; kw, Kernow ) is a historic county and ceremonial county in South West England. It is recognised as one of the Celtic nations, and is the homeland of the Cornish people. Cornwall is bordered to the north and west by the Atlantic Ocean, to the south by the English Channel, and to the east by the county of Devon, with the River Tamar forming the border between them. Cornwall forms the westernmost part of the South West Peninsula of the island of Great Britain. The southwesternmost point is Land's End and the southernmost Lizard Point. Cornwall has a population of and an area of . The county has been administered since 2009 by the unitary authority, Cornwall Council. The ceremonial county of Cornwall also includes the Isles of Scilly, which are administered separately. The administrative centre of Cornwall is Truro, its only city. Cornwall was formerly a Brythonic kingdom and subsequently a royal duchy. It is the cultural and ethnic origin of the Cornish dias ...

Newlyn Copper
Newlyn Copper was a class of arts and crafts copperware originating in Newlyn in Cornwall. History In the late 19th century the fishing industry in Cornwall was becoming unreliable as a source of income; bad weather and seasonal fluctuations brought enforced periods of inactivity. It was decided that an alternative means of employment could be gained by training the unemployed fishermen to produce items in copper. John Drew Mackenzie, an artist who settled at Newlyn was a key figure in setting up the Newlyn Industrial Class, assisted by the benefactor and local Member of Parliament, Thomas Bedford Bolitho, and artists Reginald Dick, T. C. Gotch, Perry Craft and John Pearson. After some early experiments, the class specialised in repoussé copper work and produced a wide range of domestic and decorative items. The school remained active for about thirty years after its establishment in 1890. Other known artists who produced work in the Newlyn style included: Herbert ...

Coal Scuttle
A coal scuttle, sometimes spelled ''coalscuttle'' and also called a ''hod'', "coal bucket", or "coal pail", is a bucket-like container for holding a small, intermediate supply of coal convenient to an indoor coal-fired stove or heater. Description Coal scuttles are usually made of metal and shaped as a vertical cylinder or truncated cone, with the open top slanted for pouring coal on a fire. It may have one or two handles. Homes that do not use coal sometimes use a coal scuttle decoratively. Origin The word ''scuttle'' comes, via Middle English and Old English, from the Latin word ''scutulla'', meaning "serving platter". An alternative name, ''hod'', derives from the Old French ''hotte'', meaning basket to carry on the back', apparently from Frankish *hotta or some other Germanic source (compare Middle High German hotze 'cradle')", and is also used in reference to boxes used to carry bricks or other construction materials. Infamous use In 1917, the Swedish serial killer Hilda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butter Churn
A butter churn is a device used to convert cream into butter. This is done through a mechanical process, frequently via a pole inserted through the lid of the churn, or via a crank used to turn a rotating device inside the churn. Etymology The word “butter” is believed to be derived from the Greek word bou-tyron, the approximate meaning of which is “cow cheese”. However, some believe the word came from the Scythian culture, as the ancient Greeks tended to herd sheep and goats, whose milk is not as good for butter making as that of cows, which the Scythians primarily herded. The word "churn" is from the Old English ''ċyrin,'' to churn. This is probably derived from the Old English ''cyrnel,'' "kernel," due to the appearance of butter grains after milk has been churned. The butter churn gave its name to the milk churn, early examples of which were based on butter churns. The milk churn is not, however, used for the act of churning, but rather to transport milk.

Still
A still is an apparatus used to distill liquid mixtures by heating to selectively boil and then cooling to condense the vapor. A still uses the same concepts as a basic distillation apparatus, but on a much larger scale. Stills have been used to produce perfume and medicine, water for injection (WFI) for pharmaceutical use, generally to separate and purify different chemicals, and to produce distilled beverages containing ethanol. Application Since ethanol boils at a much lower temperature than water, simple distillation can separate ethanol from water by applying heat to the mixture. Historically, a copper vessel was used for this purpose, since copper removes undesirable sulfur-based compounds from the alcohol. However, many modern stills are made of stainless steel pipes with copper linings to prevent erosion of the entire vessel and lower copper levels in the waste product (which in large distilleries is processed to become animal feed). Copper is the preferred material ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extractor Hood
A kitchen hood, exhaust hood, extractor hood, or range hood is a device containing a mechanical fan that hangs above the stove or cooktop in the kitchen. It removes airborne grease, combustion products, fumes, smoke, heat, and steam from the air by evacuation of the air and filtration. In commercial kitchens exhaust hoods are often used in combination with fire suppression devices so that fumes from a grease fire are properly vented and the fire is put out quickly. Commercial vent hoods may also be combined with a fresh air fan that draws in exterior air, circulating it with the cooking fumes, which is then drawn out by the hood. In most exhaust hoods, a filtration system removes grease (the grease trap) and other particles. Although many vent hoods exhaust air to the outside, some recirculate the air to the kitchen. In a recirculating system, filters may be used to remove odors in addition to the grease. The device is known as an extractor hood in the United Kingdom, as a rang ...

Timpani
Timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettle drums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are ''pedal timpani'' and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They are played by striking the head with a specialized drum stick called a ''timpani stick'' or ''timpani mallet''. Timpani evolved from military drums to become a staple of the classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock bands. ''Timpani'' is an Italian ...

Cigarette Case
A cigarette case (sometimes called a cigarette tin) is a sturdy container used to store small numbers of cigarettes and prevent them from being crushed. A typical cigarette case is a flat box (commonly made of metal) that opens symmetrically into two halves. Each half stores a row of cigarettes, which are often held in place by a spring or an elastic strap. Some cigarette cases are simply sturdy cases used to store standard cigarette packs. Types and uses In modern times cigarette cases are also made of plastic. Some cigarette cases come with additional features, such as built-in lighters or ashtrays. Due to the compactness of a cigarette case, being just small enough to conveniently fit in a pocket, they can also be used to store or conceal other small items. Cigarette boxes A cigarette box, much like a cigar humidor, is a larger case or tin, often stored on desktops or coffee tables. Made of wood, metal, glass, or ceramic, a cigarette box holds a larger number of ciga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
