Tin Smith
A tinsmith is a person who makes and repairs things made of tin or other light metals. The profession may sometimes also be known as a tinner, tinker, tinman, or tinplate worker; whitesmith may also refer to this profession, though the same word may also refer to an unrelated specialty of iron-smithing. By extension it can also refer to the person who deals in tinware, or tin plate. Tinsmith was a common occupation in pre-industrial times. Unlike blacksmiths (who work mostly with hot metals), tinsmiths do the majority of their work on cold metal (although they might use a hearth to heat and help shape their raw materials). Tinsmiths fabricate items such as water pitchers, forks, spoons, and candle holders. Training of tinsmiths The tinsmith learned his trade, like many other artisans, by serving an apprenticeship of 4 to 6 years with a master tinsmith. Apprenticeships were considered "indentures" and an apprentice would start first with simply cleaning the shop, polishing ...

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] |
Worshipful Company Of Tin Plate Workers
The Worshipful Company of Tin Plate Workers ''alias'' Wire Workers is one of the Livery Companies of the City of London. Tin craftsmen were originally part of the Ironmongers' Company, while the wire workers, who made wire objects such as cages, animal traps and fishhooks, were part of the Girdlers' Company. The two groups combined, and were incorporated by a Royal Charter in 1670. Now, the use of tin plate and steel wire does not remain work done by craftsmen, instead being performed by machines. Thus, the Company is no longer a trade association for craftsmen. Instead, it supports the industry through grants, as it does charities. The Tin Plate Workers' Company ranks sixty-seventh in the order of precedence An order of precedence is a sequential hierarchy of nominal importance and can be applied to individuals, groups, or organizations. Most often it is used in the context of people by many organizations and governments, for very formal and state o ... for Livery Companies ...

London
London is the capital and List of urban areas in the United Kingdom, largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Roman Empire, Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city#National capitals, Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national Government of the United Kingdom, government and Parliament of the United Kingdom, parliament.

Salammoniac
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, th ...

Ball Peen Hammer
A ball-peen or ball pein hammer, also known as a machinist's hammer, is a type of peening hammer used in metalworking. It has two heads, one flat and the other, called the peen, rounded. It is distinguished from a cross-peen hammer, diagonal-peen hammer, point-peen hammer, or chisel-peen hammer by having a hemispherical peen. Uses Besides for peening (surface hardening by impact), the ball-peen hammer is useful for many tasks, such as striking punches and chisels (usually performed with the flat face of the hammer). The peening face is useful for rounding off edges of metal pins and fasteners, such as rivets. The ball face of the hammer can also be used to make gaskets for mating surfaces. A suitable gasket material is held over the surface where a corresponding gasket is desired, and the operator will lightly tap around the edges of the mating surface to perforate the gasket material. Variants Variants include the straight-peen, diagonal-peen, and cross-peen hammer. These ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planishing Hammer
Planishing (from the Latin ''planus'', "flat") is a metalworking technique that involves finishing the surface by finely shaping and smoothing sheet metal. Process This is done by hammering with a planishing panel hammer or slapper file against a shaped surface called a ''planishing stake'' that is held in a vise or a mounting hole in a blacksmith's beak anvil, or against hand-held, shaped, metal tools that are known as ''dollies'' or ''anvils''. The shape of the stake or dolly has to match the desired work piece contour, and so they come in a variety of complex shapes. Alternatively, planishing may be done by the use of an English wheel. After approximately forming a metal object, by stretching with techniques such as sinking and raising, and then shaping and smoothing an object, metal workers use planishing for surface finishing. Planishing is a hand-driven process used in auto body repair and sheet metal Sheet metal is metal formed into thin, flat pieces, usually by an ind ...

Fire Pot
A fire pot is a container, usually earthenware, for carrying fire. Fire pots have been used since prehistoric times to transport fire from one place to another, for warmth while on the move, for cooking, in religious ceremonies and even as weapons of war. Early times Fire pots were vital to the development of civilization. Once humans had learned to contain, control and sustain fires, they had an invaluable tool for cooking food that would have otherwise not been edible. Fire pots were also useful for sharpening spears, hollowing out canoes, baking pottery, and many other tasks, such as staying warm. At first, humans relied on natural fires, caused by lightning strikes or other natural occurrences, to provide them with a flame to start their own fires. Since natural fires are not very common, humans learned how to make fires by igniting tinder from sparks caused by striking stones together, or by creating friction using a bow drill. Given the time-consuming nature of early fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soldering Iron
A soldering iron is a hand tool used in soldering. It supplies heat to melt solder so that it can flow into the joint between two workpieces. A soldering iron is composed of a heated metal tip (the ''bit'') and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Cordless irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. Simple irons, less commonly used today than in the past, were simply a large copper ''bit'' on a handle, heated in a flame. Solder melts at approximately . Soldering irons are designed to reach a temperature range of . Soldering irons are most often used for installation, repairs, and limited production work in electronics assembly. High-volume production lines use other soldering methods.Bralla, James G. ''Handbook of Manufacturing Processes - How Products, Co ...
