A chisel is a wedged hand tool with a characteristically shaped cutting edge on the end of its blade , for carving or cutting a hard material (e.g. wood , stone , or metal ). The tool can be used by hand, struck with a mallet , or applied with mechanical power . The handle and blade of some types of chisel are made of metal or wood with a sharp edge in it (such that wood chisels have lent part of their name to a particular grind ).
97-665: The Satala Aphrodite is an over-life-sized head of a bronze Hellenistic statue discovered in Satala (classical Armenia Minor , present-day Sadak, Gümüşhane Province , Turkey). Probably created in the 2nd or 1st century BC in Asia Minor , it was acquired by the British Museum in 1873, a year after its discovery. It has been widely admired since its discovery and likened to the Aphrodite of Knidos by some scholars. It

Other early examples date to the late 4th millennium BC in Egypt , Susa (Iran) and some ancient sites in China, Luristan (Iran), Tepe Sialk (Iran), Mundigak (Afghanistan), and Mesopotamia (Iraq). Tin bronze was superior to arsenic bronze in that the alloying process could be more easily controlled, and
291-544: A spoon chisel , which is bent, with the bevel on both sides. To increase the force, stone chisels are often hit with club hammers , a heavier type of hammer. Masonry chisels are typically heavy, with a relatively dull head that wedges and breaks, rather than cuts. Often used as a demolition tool, they may be mounted on a hammer drill , jackhammer , or hammered manually, usually with a heavy hammer of three pounds or more. These chisels normally have an SDS , SDS-MAX , or 1-1/8" Hex connection. Types of masonry chisels include
388-511: A "rare surviving example of ancient Armenian cultural heritage." It is widely known in Armenia as representing Anahit. Robert H. Hewsen argued that while it is "certainly a work of external origin", it is "often touted as an example of Hellenistic art in Armenia." Babken Arakelyan considered it the most prominent of all Hellenistic statues found in historical Armenia. Dickran Kouymjian described it as "magnificent" and an "important object" that
485-470: A "sweep number" is specified that expresses the part of a circle defined by the curve of the blade. The sweep number usually ranges from #1, or flat, up to #9, a semi-circle, with additional specialized gouges at higher numbers, such as the U-shaped #11, and a v-tool or parting tool, which may be an even higher number such as #41. In addition to sweep, gouges are also specified by the distance from one edge of
582-536: A Greek or Hellenistic original, or a Roman copy". In 1878 the German archaeologist Richard Engelmann, who first described it in detail, considered it a replica of the Aphrodite of Knidos (Cnidian Aphrodite). Olivier Rayet and Zhores Khachatryan believed it was either a replica of Aphrodite of Knidos or was inspired by it. Vrej Nersessian noted that it is "now generally recognized" that its style reflects that of Scopas rather than that of Praxiteles (the author of
679-524: A copper oxide (eventually becoming copper carbonate) layer is formed, the underlying metal is protected from further corrosion . This can be seen on statues from the Hellenistic period. If copper chlorides are formed, a corrosion-mode called " bronze disease " will eventually completely destroy it. Bronze, or bronze-like alloys and mixtures, were used for coins over a longer period. Bronze was especially suitable for use in boat and ship fittings prior to
776-399: A craftsperson to cut into areas that may not be possible with a regular, straight-bladed gouge. The cutting shape of a gouge may also be held in an adze , roughly as the shape of a modern-day mattock. Gouges are used in woodworking and arts. For example, a violin luthier uses gouges to carve the violin, a cabinetmaker may use it for running flutes or paring curves, or an artist may produce
873-665: A major influence on the development of cultures. In Europe, a major source of tin was the British deposits of ore in Cornwall , which were traded as far as Phoenicia in the eastern Mediterranean . In many parts of the world, large hoards of bronze artifacts are found, suggesting that bronze also represented a store of value and an indicator of social status. In Europe, large hoards of bronze tools, typically socketed axes (illustrated above), are found, which mostly show no signs of wear. With Chinese ritual bronzes , which are documented in
970-595: A more probable subject than Aphrodite. The Armenian scholar Ghevont Alishan , in his 1890 book Ayrarat , insisted that the head represents Anahit (from Iranian Anahita or Anaïtis), the Armenian equivalent of Aphrodite. Some scholars have adopted this view, based on the proximity of the location of its discovery to a major temple of Anahit in Erez (Eriza) in present-day Erzincan , around 30 km (19 mi) south of Satala. The temple at Erez, which "enjoyed great fame",
1067-421: A pair of tongs . This tool is also often used in combination with a "top fuller" type of hotcut, when the piece being cut is particularly large. Stone chisels are used to carve or cut stone, bricks or concrete slabs. To cut, as opposed to carve, a brick bolster is used; this has a wide, flat blade that is tapped along the cut line to produce a groove, then hit hard in the centre to crack the stone. Sculptors use

#17327872195631164-518: A poem titled "Head of Anahit/British Museum", which was published in Poetry magazine in 2016. Khachatur Yesayan [ hy ] , a Soviet Armenian artist, proposed in 1966 to start talks with the British Museum to move the head to Armenia. In February 2012, three months prior to the 2012 Armenian parliamentary election , Armenia's Education and Science Minister Armen Ashotyan from
1261-611: A range of alloys that may be harder than copper alone, or have other useful properties, such as strength , ductility , or machinability . The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age . The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BC (~3500 BC), and to the early 2nd millennium BC in China; elsewhere it gradually spread across regions. The Bronze Age

Nina Garsoïan suggested that it is of a "mixed Greco-Iranian type." Mardiros Ananikian wrote in The Mythology of All Races (1925) that it is a "Greek work (probably Aphrodite)" that was "worshiped by the Armenians." Soviet art historians wrote in 1962 that
1455-551: A sharper edge longer. Bronze was still used during the Iron Age, and has continued in use for many purposes to the modern day. There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin. Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades. Historical "bronzes" are highly variable in composition, as most metalworkers probably used whatever scrap
1552-633: A type of chisel that serves to carve small pieces from the material; particularly in woodworking , woodturning and sculpture . Gouges most frequently produce concave surfaces and have a U-shaped cross-section. Chisel comes from the Old French cisel , modern ciseau , Late Latin cisellum , a cutting tool, from caedere , to cut. Chisels are common in the archeological record. Chisel-cut materials have also been found. Woodworking chisels range from small hand tools for tiny details, to large chisels used to remove big sections of wood, in 'roughing out'
1649-405: A very smooth finish is not required or when the work cannot be done easily with other tools, such as a hacksaw , file, bench shears or power tools. The name cold chisel comes from its use by blacksmiths to cut metal while it was cold as compared to other tools they used to cut hot metal. Because cold chisels are used to form metal, they have a less-acute angle to the sharp portion of the blade than
1746-410: A woodworking chisel. This gives the cutting edge greater strength at the expense of sharpness. Cold chisels come in a variety of sizes, from fine engraving tools that are tapped with very light hammers, to massive tools that are driven with sledgehammers . Cold chisels are forged to shape and hardened and tempered (to a blue colour) at the cutting edge. The head of the chisel is chamfered to slow down
1843-425: Is "surely not to be identified with any Armenian deity." Terence Mitford suggests that an identification as Anaitis (Anahita) is "wholly implausible". Satala was also, for centuries, the base of Roman legions , including Legio XV Apollinaris and Legio XVI Flavia Firma . Zhores Khachatryan stated that "the Armenian origin of the statue still has to be proven". He believed that "it is more possible that it may be
1940-416: Is a better conductor of heat and electricity than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel -base alloys. Bronzes are typically ductile alloys, considerably less brittle than cast iron. Copper and its alloys have a huge variety of uses that reflect their versatile physical, mechanical, and chemical properties . Some common examples are
2037-487: Is associated with Armenia because of the location of its discovery. Kouymjian argued that the "imported head", among other archaeological findings, "testify to the interest in and market for classical art in Armenia." It may have been imported to Armenia by the royal court, possibly by Tigranes the Great , or by Greek priests and cults. The head has "long become an inextricable staple of the Armenian cultural imagery." The head

Lethaby suggested that it is a work in an Alexandrian style. Matthew P. Canepa described it as of "Hellenistic workmanship". Dyfri Williams and Lucilla Burn believe it came from a Greek or Hellenistic cult statue. Reynold Higgins suggested that "it may be

Babken Arakelian also argued in favor of the 2nd century BC, while Reynold Higgins suggested that "it may be a cast from a mould made in c. 150 BC ". Lucilla Burn argues for a late Hellenistic date, while Terence Mitford suggested it is from the "late Hellenistic or early Roman period". Brunilde Sismondo Ridgway writes that it

In the King James Version, there is no use of the word 'bronze' and 'nehoshet' was translated as 'brass'. Modern translations use 'bronze'. Bronze (nehoshet) was used widely in the Tabernacle for items such as the bronze altar (Exodus Ch.27), bronze laver (Exodus Ch.30), utensils, and mirror (Exodus Ch.38). It

These tools have longer handles for more leverage, needed to counteract the tendency of the tool to react to the downward force of the spinning wood being cut or carved. In addition, the angle and method of sharpening is different. Chisels used in metal work can be divided into two main categories: hot chisels and cold chisels. A cold chisel is a tool made of tempered steel used for cutting 'cold' metals, meaning that they are not used in conjunction with heating torches, forges, etc. Cold chisels are used to remove waste metal when

Bronze is used to make bronze wool for woodworking applications where steel wool would discolor oak . Phosphor bronze is used for ships' propellers, musical instruments, and electrical contacts. Bearings are often made of bronze for its friction properties. It can be impregnated with oil to make
2813-541: Is used to make the tone rings of many professional model banjos . The tone ring is a heavy (usually 3 lb; 1.4 kg) folded or arched metal ring attached to a thick wood rim, over which a skin, or most often, a plastic membrane (or head) is stretched – it is the bell bronze that gives the banjo a crisp powerful lower register and clear bell-like treble register. Bronze has also been used in coins; most "copper" coins are actually bronze, with about 4 percent tin and 1 percent zinc. As with coins, bronze has been used in
2910-461: Is usually assigned to the Greek goddess Aphrodite , but has been associated with her Armenian equivalent Anahit , whose major temple was located not far from Satala. Consequently, head has been widely depicted in Armenian culture as a symbol of the country's pre-Christian heritage. Although not found in modern-day Armenia, there have been unsuccessful efforts to move the fragments to Armenia. The head

The head appears on the cover of The Oxford History of Greece and the Hellenistic World (2002) and in the title sequence of the 2017 film Call Me by Your Name . The tentative association of the head with Anahit has led to it becoming a symbol of Armenian culture, and

In the Bronze Age, two forms of bronze were commonly used: "classic bronze", about 10% tin, was used in casting; and "mild bronze", about 6% tin, was hammered from ingots to make sheets. Bladed weapons were mostly cast from classic bronze, while helmets and armor were hammered from mild bronze. Modern commercial bronze (90% copper and 10% zinc) and architectural bronze (57% copper, 3% lead , 40% zinc) are more properly regarded as brass alloys because they contain zinc as

It weighs 10 kilograms (22 lb) and the bronze is 2–3 mm thick. The back of the head and neck are severely damaged, while the top of the head was damaged during excavation. The face has largely been preserved, but shows signs of oxidisation , while
6887-801: The names of individual alloys. This is done (at least in part) to prevent database searches from failing merely because of errors or disagreements in the naming of historic copper alloys. The word bronze (1730–1740) is borrowed from Middle French bronze (1511), itself borrowed from Italian bronzo ' bell metal, brass ' (13th century, transcribed in Medieval Latin as bronzium ) from either: The discovery of bronze enabled people to create metal objects that were harder and more durable than previously possible. Bronze tools , weapons , armor , and building materials such as decorative tiles were harder and more durable than their stone and copper (" Chalcolithic ") predecessors. Initially, bronze
6984-581: The period of the Chola empire in Tamil Nadu used bronze to create intricate statues via the lost-wax casting method with ornate detailing depicting the deities of Hinduism . The art form survives to this day, with many silpis, craftsmen, working in the areas of Swamimalai and Chennai . In antiquity other cultures also produced works of high art using bronze. For example: in Africa, the bronze heads of
7081-424: The preferred metal for bells in the form of a high tin bronze alloy known as bell metal , which is typically about 23% tin. Nearly all professional cymbals are made from bronze, which gives a desirable balance of durability and timbre . Several types of bronze are used, commonly B20 bronze , which is roughly 20% tin, 80% copper, with traces of silver, or the tougher B8 bronze made from 8% tin and 92% copper. As
7178-452: The proprietary Oilite and similar material for bearings. Aluminum bronze is hard and wear-resistant, and is used for bearings and machine tool ways. The Doehler Die Casting Co. of Toledo, Ohio were known for the production of Brastil , a high tensile corrosion resistant bronze alloy. The Seagram Building on New York City 's Park Avenue is the "iconic glass box sheathed in bronze, designed by Mies van der Rohe ." The Seagram Building
7275-454: The ready availability of silicon bronze brazing rod, which allows color-matched repair of defects in castings. Aluminum is also used for the structural metal aluminum bronze. Bronze parts are tough and typically used for bearings , clips, electrical connectors and springs . Bronze also has low friction against dissimilar metals, making it important for cannons prior to modern tolerancing , where iron cannonballs would otherwise stick in
7372-626: The resulting alloy was stronger and easier to cast. Also, unlike those of arsenic , metallic tin and the fumes from tin refining are not toxic . Tin became the major non-copper ingredient of bronze in the late 3rd millennium BC. Ores of copper and the far rarer tin are not often found together (exceptions include Cornwall in the United Kingdom, one ancient site in Thailand and one in Iran), so serious bronze work has always involved trade with other regions. Tin sources and trade in ancient times had
7469-498: The ruling Republican Party called for moving the fragments of the statue to Armenia. Ashotyan claimed that this was a personal and not a political initiative. By the end of February some 20,000 signatures were collected by the RPA-affiliated Armenia Youth Fund demanding that the fragments be moved to Armenia. One proponent of the campaign argued that the "sentimental value of the goddess Anahit's statue
7566-406: The same long axis. If the bevel of the blade is on the outer surface of the curve the gouge is called an 'outcannel' gouge, otherwise it is known as an 'incannel' gouge. Gouges with angled rather than curved blades are often called 'V-gouges' or 'vee-parting tools'. The blade geometry is defined by a semi-standardized numbering system that varies by manufacturer and country of origin. For each gouge
7663-431: The shape of a pattern or design. Typically, in woodcarving , one starts with a larger tool, and gradually progresses to smaller tools to finish the detail. One of the largest types of chisel is the slick , used in timber frame construction and wooden shipbuilding. There are many types of woodworking chisels used for specific purposes, such as: Woodturners use a woodworking gouge or chisel designed to cut wood as it
7760-478: The shipping of tin around the Mediterranean and from Britain, limiting supplies and raising prices. As the art of working in iron improved, iron became cheaper and improved in quality. As later cultures advanced from hand- wrought iron to machine- forged iron (typically made with trip hammers powered by water), blacksmiths also learned how to make steel . Steel is stronger and harder than bronze and holds
7857-409: The statue has an "enormous significance". Armenian President Vahagn Khachaturyan , Parliament Speaker Alen Simonyan , Prime Minister Nikol Pashinyan and his wife Anna Hakobyan attended the opening of the exhibition on September 21, the country's independence day. In a social media post, Pashinyan said, "Welcome back, Goddess". Armenian neopagans celebrated the "return" of Anahit with a ceremony at
7954-436: The statue of a Roman pagan goddess" as it was found near the site of a Roman camp inhabited during the time period of its assumed creation. Russell argued that Satala "appears to have been sufficiently important in ancient times to have been a religious centre, although there is nothing to suggest that the shrine was Armenian, or Zoroastrian" and suggested that it was a "Roman military shrine." The head has been widely admired in
8051-400: The subject is in a "pensive mood". Herbert Maryon described its creation as a good example of a technique which began in the 4th century BC: They modelled a head, perhaps in clay , and formed the outer mould in the usual manner. They then lined the mould with thin slabs of wax, about 3 ⁄ 16 inch (4.8 mm) thick, pressing the wax fairly closely into all the forms. To ensure
8148-469: The tin content in a bell or cymbal rises, the timbre drops. Bronze is also used for the windings of steel and nylon strings of various stringed instruments such as the double bass , piano, harpsichord , and guitar. Bronze strings are commonly reserved on pianoforte for the lower pitch tones, as they possess a superior sustain quality to that of high-tensile steel. Bronzes of various metallurgical properties are widely used in struck idiophones around
8245-439: The unusual and desirable property of expanding slightly just before they set, thus filling the finest details of a mould. Then, as the bronze cools, it shrinks a little, making it easier to separate from the mould. The Assyrian king Sennacherib (704–681 BC) claims to have been the first to cast monumental bronze statues (of up to 30 tonnes) using two-part moulds instead of the lost-wax method . Bronze statues were regarded as
8342-419: The wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion. Bronze is still commonly used in ship propellers and submerged bearings. In the 20th century, silicon was introduced as the primary alloying element, creating an alloy with wide application in industry and the major form used in contemporary statuary . Sculptors may prefer silicon bronze because of
8439-657: The world was by the Roman Bronze Works and General Bronze Corporation in 1952. The material used for the fountain, known as statuary bronze, is a quaternary alloy made of copper, zinc, tin, and lead, and traditionally golden brown in color. This was made for the Andrew W. Mellon Memorial Fountain in Federal Triangle in Washington, DC. Another example of the massive, ornate design projects of bronze, and attributed to General Bronze/Roman Bronze Works were
8536-710: The world, notably bells, singing bowls, gongs , cymbals, and other idiophones from Asia. Examples include Tibetan singing bowls , temple bells of many sizes and shapes, Javanese gamelan , and other bronze musical instruments . The earliest bronze archeological finds in Indonesia date from 1–2 BC, including flat plates probably suspended and struck by a wooden or bone mallet. Ancient bronze drums from Thailand and Vietnam date back 2,000 years. Bronze bells from Thailand and Cambodia date back to 3600 BC. Some companies are now making saxophones from phosphor bronze (3.5 to 10% tin and up to 1% phosphorus content). Bell bronze/B20
8633-530: Was established, according to tradition, by Tigranes the Great in the first century BC and was the "wealthiest and most venerable in Armenia" per Cicero . Both Satala and Erez were located in the Acilisene (Եկեղեաց, Ekełeats‘) province of classical Armenia Minor . Anahit's cult in Acilisene was so great that it was known as Anaetica (the land of Anahit/Anaïtis). Her cult at Eriza was closely linked with
8730-429: Was followed by the Iron Age starting about 1300 BC and reaching most of Eurasia by about 500 BC, although bronze continued to be much more widely used than it is in modern times. Because historical artworks were often made of brasses (copper and zinc) and bronzes of different metallic compositions, modern museum and scholarly descriptions of older artworks increasingly use the generalized term "copper alloy" instead of
8827-650: Was found in 1872 by an old man named Youssouf who was digging in his field with a pickaxe , at a depth of around 2 feet (0.61 m), near the village of Sadak [ tr ] , in what was once the Roman fortress of Satala , on the Kelkit River , north of Erzincan (then in the Ottoman Empire , now Turkey). The man uncovered fragments of a bronze statue, including the head and a hand. Arthur Frothingham reported two decades later that according to locals
8924-454: Was found together with the head, holds a fragment of drapery . Lâtife Summerer suggested that the original statue was more than 2 metres (6 ft 7 in) in height. The sculpture was initially dated to the 4th century BC, but this was subsequently questioned and it was placed in the 2nd century BC. Modern scholars and the British Museum place its creation in the 2nd or 1st century BC. Sara Anderson Immerwahr argued that its style
9021-525: Was made out of copper and arsenic or from naturally or artificially mixed ores of those metals, forming arsenic bronze . The earliest known arsenic-copper-alloy artifacts come from a Yahya Culture (Period V 3800-3400 BCE) site, at Tal-i-Iblis on the Iranian plateau , and were smelted from native arsenical copper and copper-arsenides, such as algodonite and domeykite . The earliest tin-copper-alloy artifact has been dated to c. 4650 BC , in
9118-474: Was mentioned in the account of Moses holding up a bronze snake on a pole in Numbers Ch.21. In First Kings, it is mentioned that Hiram was very skilled in working with bronze, and he made many furnishings for Solomon's Temple including pillars, capitals, stands, wheels, bowls, and plates, some of which were highly decorative (see I Kings 7:13-47). Bronze was also widely used as battle armor and helmet, as in
9215-424: Was not only the most expensive building of its time — $ 36 million — but it was the first building in the world with floor-to-ceiling glass walls. Mies van der Rohe achieved the crisp edges that were custom-made with specific detailing by General Bronze and "even the screws that hold in the fixed glass-plate windows were made of brass." Bronze is widely used for casting bronze sculptures . Common bronze alloys have
9312-481: Was on hand; the metal of the 12th-century English Gloucester Candlestick is bronze containing a mixture of copper, zinc, tin, lead, nickel, iron, antimony, arsenic and an unusually large amount of silver – between 22.5% in the base and 5.76% in the pan below the candle. The proportions of this mixture suggest that the candlestick was made from a hoard of old coins. The 13th-century Benin Bronzes are in fact brass, and
9409-593: Was the first time that an entire building was sheathed in bronze. The General Bronze Corporation fabricated 3,200,000 pounds (1,600 tons) of bronze at its plant in Garden City, New York . The Seagram Building is a 38-story, 516-foot bronze-and- topaz -tinted glass building. The building looks like a "squarish 38-story tower clad in a restrained curtain wall of metal and glass." "Bronze was selected because of its color, both before and after aging, its corrosion resistance, and its extrusion properties. In 1958, it
