73-601: The Atlantic Bronze Age is a term that has never been formally defined. Some take its meaning to be a label for the period spanning approximately 1300–700 BC in Britain, France, Ireland, Portugal and Spain; that is, the Atlantic coast of Europe. Others assign it to a cultural complex of the Bronze Age period in prehistoric Europe that is defined by the culture prevalent at this time and location. The Atlantic Bronze Age

146-601: A Vinča culture site in Pločnik ( Serbia ), and believed to have been smelted from a natural tin-copper ore, stannite . 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

219-534: A context of extreme aridification in the area in the wake of the 4.2-kiloyear climatic event , which roughly coincided with the transition from the Copper Age to the Bronze Age. Increased precipitation and recovery of the water table from about 1800 BC onward should have led to the forsaking of the motillas (which may have flooded) and the redefinition of the relation of the inhabitants of the territory with

292-524: 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

365-426: A far-ranging trade network. This network imported tin and charcoal to Cyprus , where copper was mined and alloyed with the tin to produce bronze . Bronze objects were then exported far and wide and supported the trade. Isotopic analysis of the tin in some Mediterranean bronze objects indicates it came from as far away as Great Britain . Knowledge of navigation was well developed at this time and reached

438-679: A link to the East. It was preceded by the Yamnaya culture and succeeded by the western Corded Ware culture . The eastern Corded Ware culture ( Fatyanovo–Balanovo culture ) gave rise to the Abashevo culture , followed by the Sintashta culture , where the earliest known spoked-wheel chariots have been found, dating from c.  2000 BC . The Catacomb culture in the Pontic steppe was succeeded by

511-665: 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

584-438: A network of palace states that developed rigid hierarchical, political, social and economic systems. At the head of this society was the king, known as wanax . A study in the journal Antiquity from 2013 reported the discovery of a tin bronze foil from the Pločnik archaeological site dated to c.  4650 BC , as well as 14 other artefacts from Serbia and Bulgaria dated to before 4000 BC, showed that early tin bronze

657-569: A peak of skill not exceeded until a method was discovered (or perhaps rediscovered) to determine longitude around AD 1750. Around 1600 BC, the eruption of Thera destroyed the site of Akrotiri and damaged Minoan sites in eastern Crete . The further impact of this event is poorly understood. Starting in the 15th century BC, the Mycenaeans began to spread their influence throughout the Aegean and Western Anatolia. By c.  1450 BC ,

730-494: 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

803-551: 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

876-670: A variety of bronze swords , including carp-tongue swords, are usually found buried in lakes, rivers, or rocky outcrops. Elite feasting equipment such as spits, kettles, and meat hooks have also been found from central Portugal to Scotland. It is during this period that the Celts rose to prominence in Europe In particular, the Celtic language may have developed as an Atlantic lingua franca . Communities may have adopted elite status markers such as grip-tongue swords and bronze sheet metalwork from

949-416: 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

1022-412: Is also known for a relatively large number of Early Bronze Age Burials . Bronze Bronze is an alloy consisting primarily of copper , commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium , manganese , nickel , or zinc ) and sometimes non-metals, such as phosphorus , or metalloids , such as arsenic or silicon . These additions produce

1095-749: Is characterized by cremation burials. It includes the Lusatian culture in eastern Germany and Poland (1300–500 BC) that continues into the Iron Age . The Central European Bronze Age is followed by the Iron Age Hallstatt culture (800–450 BC). The Italian Bronze Age is conditionally divided into four periods: The Early Bronze Age (2300–1700 BC), the Middle Bronze Age (1700–1350 BC), the Recent Bronze Age (1350–1150 BC),

1168-400: Is characterized by economic and cultural exchange between far-flung communities, resulting in a high degree of cultural similarity seen in coastal communities ranging from central Portugal in the south of coastal Europe, through Galicia (Spain), the Atlantic coast of France, including Armorica (Brittany) to Cornwall in southwest England and as far north as Scotland . This is evidenced by

1241-439: Is divided into the periods I–VI, according to Oscar Montelius . Period Montelius V, already belongs to the Iron Age in other regions. In Great Britain , the Bronze Age is considered to have been the period from around 2100 to 700 BC. Immigration brought new people to the islands from the continent. Recent tooth enamel isotope research on bodies found in early Bronze Age graves around Stonehenge indicate that at least some of

1314-527: Is likely that 'nehoshet' refers to copper and its alloys with tin, now called bronze. 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

1387-453: Is used to make hammers , mallets , wrenches and other durable tools to be used in explosive atmospheres or in the presence of flammable vapors. 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

1460-541: 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

1533-589: The Cypriots , the lost waxing technique was introduced to create several hundred bronze statuettes and other tools. The Nuragic civilization survived throughout the early Iron Age when the sanctuaries were still in use, stone statues were crafted and some Nuraghi were reused as temples. In northern Germany , Denmark , Sweden and Norway , Bronze Age cultures manufactured many distinctive and artistic artifacts. This includes lur horns, horned ceremonial helmets, sun discs, gold jewelry and some unexplained finds like

1606-560: The Etruscans were making bronze mirrors in the sixth century BC, and Greek and Roman mirrors followed the same pattern. Although other materials such as speculum metal had come into use, and Western glass mirrors had largely taken over, bronze mirrors were still being made in Japan and elsewhere in the eighteenth century, and are still made on a small scale in Kerala , India. Bronze is

1679-513: The Golden Age , when men lived among the gods; the Silver age , where youth lasted a hundred years; and the Bronze Age , the era of heroes. It was first adopted for a sports event at the 1904 Summer Olympics . At the 1896 event, silver was awarded to winners and bronze to runners-up, while at 1900 other prizes were given rather than medals. Bronze is the normal material for the related form of

1752-756: The Kingdom of Benin ; in Europe, Grecian bronzes typically of figures from Greek mythology ; in east Asia , Chinese ritual bronzes of the Shang and Zhou dynasty —more often ceremonial vessels but including some figurine examples. Bronze continues into modern times as one of the materials of choice for monumental statuary. Tiffany Glass Studios, made famous by Louis C. Tiffany commonly referred to his product as favrile glass or " Tiffany glass ," and used bronze in their artisan work for his Tiffany lamps . The largest and most ornate bronze fountain known to be cast in

1825-673: The Multi-cordoned Ware culture , and the Srubnaya culture from c.  the 17th century BC . Important sites include: In Central Europe , the early Bronze Age Unetice culture (2300–1600 BC) includes numerous smaller groups like the Straubingen , Adlerberg and Hatvan cultures. Some very rich burials, such as the one located at Leubingen (today part of Sömmerda ) with grave gifts crafted from gold, point to an increase of social stratification already present in

1898-481: The Urnfield period (Bronze D and Hallstatt A) and they must also have acquired the skills for their production, and ritual knowledge about their proper treatment involving deposition. These changes may indicate processes related to language change. The emergence of Celtic languages with a Proto-Celtic homeland in west-central Europe can be explained by elite contact from east to west. However, this view contrasts with

1971-593: The bronze "gong" from Balkåkra in Sweden. Some linguists believe that an early Indo-European language was introduced to the area probably around 2000 BC, which eventually became Proto-Germanic , the last common ancestor of the Germanic languages . This would fit with the apparently unbroken evolution of the Nordic Bronze Age into the most probably ethnolinguistically Germanic Pre-Roman Iron Age . The age

2044-550: The plaquette , normally a rectangular work of art with a scene in relief , for a collectors' market. Bronze is also associated with eighth wedding anniversaries. There are over 125 references to bronze ('nehoshet'), which appears to be the Hebrew word used for copper and any of its alloys. However, the Old Testament era Hebrews are not thought to have had the capability to manufacture zinc (needed to make brass) and so it

2117-623: The 12th-century Romanesque Baptismal font at St Bartholomew's Church, Liège is sometimes described as bronze and sometimes as brass . 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

2190-555: The 36th–23rd centuries BC. The culture was predominantly nomadic, with some agriculture practiced near rivers and a few hill-forts. The Catacomb culture , covering several related archaeological cultures, was first to introduce corded pottery decorations into the steppes and showed a profuse use of the polished battle ax, providing a link to the West. Parallels with the Afanasevo culture , including provoked cranial deformations, provide

2263-601: The Final Bronze Age (1150–950 BC). During the second millennium BC, the Nuragic civilization flourished in the island of Sardinia . It was a rather homogeneous culture, more than 7000 imposing stone tower-buildings known as Nuraghe were built by this culture all over the island, along with other types of monuments such as the megaron temples, the monumental Giants' graves and the holy well temples . Sanctuaries and larger settlements were also built starting from

2336-629: The Unetice culture. All in all, cemeteries of this period are rare and of small size. The Unetice culture is followed by the middle Bronze Age (1600–1200 BC) Tumulus culture , which is characterized by inhumation burials in tumuli (barrows). In the eastern Hungarian Körös tributaries, the early Bronze Age first saw the introduction of the Makó culture , followed by the Otomani and Gyulavarsánd cultures. The late Bronze Age Urnfield culture (1300–750 BC)

2409-452: The barrel. It is still widely used today for springs, bearings, bushings, automobile transmission pilot bearings, and similar fittings, and is particularly common in the bearings of small electric motors . Phosphor bronze is particularly suited to precision-grade bearings and springs. It is also used in guitar and piano strings. Unlike steel, bronze struck against a hard surface will not generate sparks, so it (along with beryllium copper )

2482-510: The centuries around 2000 BC when copper was alloyed with tin and used to manufacture Ballybeg type flat axes and associated metalwork. The preceding period is known as the Copper Age and is characterised by the production of flat axes , daggers , halberds and awls in copper. The period is divided into three phases: Early Bronze Age 2000–1500 BC; Middle Bronze Age 1500–1200 BC and Late Bronze Age 1200– c.  500 BC . Ireland

2555-546: The environment, with the development of the Iberian oppida mode of settlement. The Atlantic Bronze Age is a cultural complex of the Bronze Age period of approximately 1300–700 BC that includes different cultures in Portugal , Andalusia , Galicia , France , Britain , and Ireland and is marked by economic and cultural exchange that led to the high degree of cultural similarity exhibited by coastal communities, including

2628-721: The fields of engineering, architecture and military infrastructure, while trade over vast areas of the Mediterranean was essential for the Mycenaean economy. Their syllabic script, the Linear B , offers the first written records of the Greek language and their religion already included several deities that can be also found in the Olympic Pantheon . Mycenaean Greece was dominated by a warrior elite society and consisted of

2701-590: The first tin bronze alloys in the Near East . This bronze production lasted for c. 500 years in the Balkans but disappeared at the end of the 5th millennium, coinciding with the " collapse of large cultural complexes in north-eastern Bulgaria and Thrace in the late fifth millennium BC". Tin bronzes using cassiterite tin were subsequently reintroduced to the area some 1500 years later. The Aegean Bronze Age begins around 3200 BC when civilizations first established

2774-1075: The frequent use of stone as chevaux-de-frise , the construction of cliff castles, and a similarity of domestic architecture and living spaces, sometimes characterized by roundhouses. Trade contacts extended northwards and eastwards to Sweden and Denmark and eastwards as far as the Mediterranean. This Bronze Age culture was characterized by distinct regional centers of metal production, linked by regular maritime trade. The main centers were in southern England and Ireland, northwestern France, and western Iberia (Spain and Portugal). Items associated with this culture are often found in hoards or deposited in ritual areas. Metal finds have typically been preserved in watery contexts such as rivers, lakes, and bogs. This cultural complex includes various items, such as socketed and double-ring bronze axes, sometimes found buried in large hoards in Brittany and Galicia. Military equipment such as lunate spearheads, V-notched shields, and

2847-584: The frequent use of stones as chevaux-de-frise , the establishment of cliff castles , or the domestic architecture sometimes characterized by the round houses. Commercial contacts extended from Sweden and Denmark to the Mediterranean . The period was defined by a number of distinct regional centres of metal production, unified by a regular maritime exchange of some of their products. The major centres were southern England and Ireland, north-western France, and western Iberia. The Bronze Age in Ireland commenced in

2920-545: The high electrical conductivity of pure copper, low-friction properties of bearing bronze (bronze that has a high lead content— 6–8%), resonant qualities of bell bronze (20% tin, 80% copper), and resistance to corrosion by seawater of several bronze alloys. The melting point of bronze varies depending on the ratio of the alloy components and is about 950 °C (1,742 °F). Bronze is usually nonmagnetic, but certain alloys containing iron or nickel may have magnetic properties. Typically bronze oxidizes only superficially; once

2993-699: The highest form of sculpture in Ancient Greek art , though survivals are few, as bronze was a valuable material in short supply in the Late Antique and medieval periods. Many of the most famous Greek bronze sculptures are known through Roman copies in marble, which were more likely to survive. In India, bronze sculptures from the Kushana ( Chausa hoard ) and Gupta periods ( Brahma from Mirpur-Khas , Akota Hoard, Sultanganj Buddha ) and later periods ( Hansi Hoard) have been found. Indian Hindu artisans from

3066-415: The hills and into the fertile valleys . Large livestock ranches developed in the lowlands which appear to have contributed to economic growth and inspired increasing forest clearances. The Deverel–Rimbury culture began to emerge in the second half of the 'Middle Bronze Age' ( c.  1400 –1100 BC) to exploit these conditions. Cornwall was a major source of tin for much of western Europe and copper

3139-445: The immigrants came from the area of modern Switzerland . The Beaker people displayed different behaviors from the earlier Neolithic people and cultural change was significant. The rich Wessex culture developed in southern Britain at this time. Additionally, the climate was deteriorating; where once the weather was warm and dry it became much wetter as the Bronze Age continued, forcing the population away from easily defended sites in

3212-429: The inscriptions they carry and from other sources, the case is clear. These were made in enormous quantities for elite burials, and also used by the living for ritual offerings. Though bronze is generally harder than wrought iron , with Vickers hardness of 60–258 vs. 30–80, the Bronze Age gave way to the Iron Age after a serious disruption of the tin trade: the population migrations of around 1200–1100 BC reduced

3285-538: The larger hilltop settlements, and the elite using violence in practical and ideological terms to clamp down on the population. Ecological degradation, landscape opening, fires, pastoralism, and maybe tree cutting for mining have been suggested as reasons for the collapse. The culture of the motillas , developed an early system of groundwater supply plants (the so-called motillas ) in the upper Guadiana basin (in Iberian Peninsula's southern meseta ) in

3358-468: The late fifth millennium BC". Tin bronzes using cassiterite tin would be reintroduced to the area again some 1,500 years later. The Maykop culture was the major early Bronze Age culture in the North Caucasus . Some scholars date arsenical bronze artifacts in the region as far back as the mid-4th millennium BC. The Yamnaya culture was a late copper age /early Bronze Age culture dating to

3431-471: The late second millennium BC to host these religious structures along with other structures such ritual pools, fountains and tanks, large stone roundhouses with circular benches used for the meeting of the leaders of the chiefdoms and large public areas. Bronze tools and weapons were widespread and their quality increased thanks to the contacts between the Nuragic people and Eastern Mediterranean peoples such as

3504-824: The main alloying ingredient. They are commonly used in architectural applications. Plastic bronze contains a significant quantity of lead, which makes for improved plasticity, and was possibly used by the ancient Greeks in ship construction. Silicon bronze has a composition of Si: 2.80–3.80%, Mn: 0.50–1.30%, Fe: 0.80% max., Zn: 1.50% max., Pb: 0.05% max., Cu: balance. Other bronze alloys include aluminium bronze , phosphor bronze , manganese bronze, bell metal , arsenical bronze , speculum metal , bismuth bronze , and cymbal alloys . Copper-based alloys have lower melting points than steel or iron and are more readily produced from their constituent metals. They are generally about 10 percent denser than steel, although alloys using aluminum or silicon may be slightly less dense. Bronze

3577-462: The manufacture of various types of medals for centuries, and " bronze medals " are known in contemporary times for being awarded for third place in sporting competitions and other events. The term is now often used for third place even when no actual bronze medal is awarded. The usage in part arose from the trio of gold , silver and bronze to represent the first three Ages of Man in Greek mythology:

3650-673: The massive bronze doors to the United States Supreme Court Building in Washington, DC. Before it became possible to produce glass with acceptably flat surfaces, bronze was a standard material for mirrors. Bronze was used for this purpose in many parts of the world, probably based on independent discoveries. Bronze mirrors survive from the Egyptian Middle Kingdom (2040–1750 BC), and China from at least c.  550 BC . In Europe,

3723-721: The more widely accepted view that Celtic origins are linked to the central European Hallstatt C culture . Bronze Age Europe Arsenical bronze was produced in some areas from the 4th millennium BC onwards, prior to the introduction of tin bronze. Tin bronze foil had already been produced in southeastern Europe on a small scale in the Chalcolithic era, with examples from Pločnik in Serbia dated to c.  4650 BC , as well as 14 other artefacts from Bulgaria and Serbia dated to before 4000 BC, showing that early tin bronze developed independently in Europe 1500 years before

3796-704: The most important finds were done in Isleham (more than 6500 pieces). Preceded by the Chalcolithic sites of Los Millares , the Argaric culture flourished in southeastern Iberia in from 2200 BC to 1550 BC, when depopulation of the area ensued along with disappearing of copper–bronze–arsenic metallurgy. The most accepted model for El Argar has been that of an early state society, most particularly in terms of class division, exploitation, and coercion, with agricultural production, maybe also human labour, controlled by

3869-801: 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

3942-519: The palace of Knossos was ruled by a Mycenaean elite who formed a hybrid Minoan-Mycenaean culture. Mycenaeans also colonized several other Aegean islands, reaching as far as Rhodes . Thus the Mycenaeans became the dominant power of the region, marking the beginning of the Mycenaean 'Koine' era (from Greek : Κοινή , common), a highly uniform culture that spread in mainland Greece and the Aegean. The Mycenaean Greeks introduced several innovations in

4015-581: 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

4088-424: 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

4161-452: 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

4234-454: 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

4307-690: 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

4380-415: 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

4453-469: 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

4526-439: 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

4599-419: 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

4672-657: 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

4745-710: 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

4818-940: Was extracted from sites such as the Great Orme mine in northern Wales . Social groups appear to have been tribal but with growing complexity and hierarchies becoming apparent. Also, the burial of dead (which until this period had usually been communal) became more individual. For example, whereas in the Neolithic a large chambered cairn or long barrow was used to house the dead, the 'Early Bronze Age' saw people buried in individual barrows (also commonly known and marked on modern British Ordnance Survey maps as Tumuli), or sometimes in cists covered with cairns . The greatest quantities of bronze objects found in England were discovered in East Cambridgeshire , where

4891-429: 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

4964-525: 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

5037-474: 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
