98-623: The early Iron Age site, first excavated in 1917, was most prosperous in the 8th – 6th centuries BCE; later it became a minor satellite of Knossos and continued to be occupied into the Byzantine period . It comprises two acropoleis with an Archaic-period agora between them. Almost the whole of the city and its necropolis have been excavated, confirming that this is a post-Minoan Greek habitation; its inscriptions are in Dorian dialect. Traces of fortifications have been discovered. There

196-593: 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

294-520: A Celtiberian stronghold against Roman invasions. İt dates more than 2500 years back. The site was researched by Francisco Martins Sarmento starting from 1874. A number of amphoras (containers usually for wine or olive oil), coins, fragments of pottery, weapons, pieces of jewelry, as well as ruins of a bath and its pedra formosa ( lit.   ' handsome stone ' ) revealed here. The Iron Age in Central Asia began when iron objects appear among

392-681: A combination of bivalve moulds of distinct southern tradition and the incorporation of piece mould technology from the Zhongyuan . The products of the combination of these two periods are bells, vessels, weapons and ornaments, and the sophisticated cast. An Iron Age culture of the Tibetan Plateau has been associated tentatively with the Zhang Zhung culture described by early Tibetan writings. In Japan, iron items, such as tools, weapons, and decorative objects, are postulated to have entered Japan during

490-518: 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

588-655: 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

686-546: 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

784-481: A universal "Bronze Age", and many areas transitioned directly from stone to iron. Some archaeologists believe that iron metallurgy was developed in sub-Saharan Africa independently from Eurasia and neighbouring parts of Northeast Africa as early as 2000 BC . The concept of the Iron Age ending with the beginning of the written historiographical record has not generalized well, as written language and steel use have developed at different times in different areas across

882-416: 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

980-400: Is abundant naturally, temperatures above 1,250 °C (2,280 °F) are required to smelt it, impractical to achieve with the technology available commonly until the end of the second millennium BC. In contrast, the components of bronze—tin with a melting point of 231.9 °C (449.4 °F) and copper with a relatively moderate melting point of 1,085 °C (1,985 °F)—were within

1078-567: Is also a large communal cistern dug between the late 3rd and early 2nd century BCE, which contained Archaic inscriptions, one of which, famous as the Dreros inscription , the "sacred law of Dreros", is the earliest complete record of constitutional law found in Greece , which mentions the Dorian Cretan titles kosmos and damios . In Hellenistic times, Dreros declined in importance to the extent that it

1176-646: Is also speculated that Early Iron Age sites may exist in Kandarodai , Matota, Pilapitiya and Tissamaharama . The earliest undisputed deciphered epigraphy found in the Indian subcontinent are the Edicts of Ashoka of the 3rd century BC, in the Brahmi script . Several inscriptions were thought to be pre-Ashokan by earlier scholars; these include the Piprahwa relic casket inscription,

1274-493: 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 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

1372-522: Is considered to last from c.  1200 BC (the Bronze Age collapse ) to c.  550 BC (or 539 BC ), roughly the beginning of historiography with Herodotus , marking the end of the proto-historical period. In China , because writing was developed first, there is no recognizable prehistoric period characterized by ironworking, and the Bronze Age China transitions almost directly into

1470-534: Is divided into two periods based on the Hallstatt culture (early Iron Age) and La Tène (late Iron Age) cultures. Material cultures of Hallstatt and La Tène consist of 4 phases (A, B, C, D). The Iron Age in Europe is characterized by an elaboration of designs of weapons, implements, and utensils. These are no longer cast but hammered into shape, and decoration is elaborate and curvilinear rather than simple rectilinear;

1568-851: Is from Malhar and its surrounding area. This site is assumed as the center for smelted bloomer iron to this area due to its location in the Karamnasa River and Ganga River. This site shows agricultural technology as iron implements sickles, nails, clamps, spearheads, etc., by at least c. 1500 BC. Archaeological excavations in Hyderabad show an Iron Age burial site. The beginning of the 1st millennium BC saw extensive developments in iron metallurgy in India. Technological advancement and mastery of iron metallurgy were achieved during this period of peaceful settlements. One ironworking centre in East India has been dated to

1666-418: 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 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

1764-513: 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

1862-540: Is likely that the use of ironware made of steel had already begun in the third millennium BC in Central Anatolia". Souckova-Siegolová (2001) shows that iron implements were made in Central Anatolia in very limited quantities about 1800 BC and were in general use by elites, though not by commoners, during the New Hittite Empire (≈1400–1200 BC). Similarly, recent archaeological remains of iron-working in

1960-616: Is recorded to extend 10 ha (25 acres) by 800 BC and grew to 50 ha (120 acres) by 700–600 BC to become a town. The skeletal remains of an Early Iron Age chief were excavated in Anaikoddai, Jaffna . The name "Ko Veta" is engraved in Brahmi script on a seal buried with the skeleton and is assigned by the excavators to the 3rd century BC. Ko, meaning "King" in Tamil, is comparable to such names as Ko Atan and Ko Putivira occurring in contemporary Brahmi inscriptions in south India. It

2058-506: Is singularly scarce in collections of Egyptian antiquities. Bronze remained the primary material there until the conquest by the Neo-Assyrian Empire in 671 BC. The explanation of this would seem to be that the relics are in most cases the paraphernalia of tombs, the funeral vessels and vases, and iron being considered an impure metal by the ancient Egyptians it was never used in their manufacture of these or for any religious purposes. It

2156-636: Is the final epoch of the three historical Metal Ages , after the Chalcolithic and Bronze Age . It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic , Mesolithic and Neolithic ) and Bronze Age. These concepts originated for describing Iron Age Europe and

2254-411: Is the mass production of tools and weapons made not just of found iron, but from smelted steel alloys with an added carbon content. Only with the capability of the production of carbon steel does ferrous metallurgy result in tools or weapons that are harder and lighter than bronze . Smelted iron appears sporadically in the archeological record from the middle Bronze Age . Whilst terrestrial iron

2352-453: 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

2450-541: 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

2548-541: The Ancient Near East . The indigenous cultures of the New World did not develop an iron economy before 1500 . Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of smelted iron (especially steel tools and weapons) replaces their bronze equivalents in common use. In Anatolia and

2646-894: The Badli pillar inscription , the Bhattiprolu relic casket inscription, the Sohgaura copper plate inscription , the Mahasthangarh Brahmi inscription, the Eran coin legend, the Taxila coin legends, and the inscription on the silver coins of Sophytes . However, more recent scholars have dated them to later periods. Dates are approximate; consult particular article for details.

2744-640: The Caucasus , or Southeast Europe , the Iron Age began during the late 2nd millennium BC ( c. 1300 BC). In the Ancient Near East , this transition occurred simultaneously with the Late Bronze Age collapse , during the 12th century BC (1200–1100 BC). The technology soon spread throughout the Mediterranean Basin region and to South Asia between the 12th and 11th century BC. Its further spread to Central Asia , Eastern Europe , and Central Europe

2842-547: 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

2940-655: The Ganges Valley in India have been dated tentatively to 1800 BC. Tewari (2003) concludes that "knowledge of iron smelting and manufacturing of iron artifacts was well known in the Eastern Vindhyas and iron had been in use in the Central Ganga Plain, at least from the early second millennium BC". By the Middle Bronze Age increasing numbers of smelted iron objects (distinguishable from meteoric iron by

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

Early evidence for iron technology in Sub-Saharan Africa can be found at sites such as KM2 and KM3 in northwest Tanzania and parts of Nigeria and the Central African Republic. Nubia was one of the relatively few places in Africa to have a sustained Bronze Age along with Egypt and much of the rest of North Africa . Archaeometallurgical scientific knowledge and technological development originated in numerous centers of Africa;

"Iron Age" in the context of China is used sometimes for the transitional period of c.  900 BC to 100 BC during which ferrous metallurgy was present even if not dominant. The Iron Age in the Ancient Near East is believed to have begun after the discovery of iron smelting and smithing techniques in Anatolia , the Caucasus or Southeast Europe during

The mortuary evidence suggests that the initial use of iron in Lingnan belongs to the mid-to-late Warring States period (from about 350 BC). Important non-precious husi style metal finds include iron tools found at the tomb at Guwei-cun of the 4th century BC. The techniques used in Lingnan are

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

3822-614: The "Dreros Triad." Two Eteocretan inscriptions on blocks of grey schist were excavated in 1936 by Pierre Demargne and Henri van Effenterre from the western part of the large cistern mentioned above. These inscriptions were housed in the museum at Neapolis, but were lost during the Germano-Italian occupation of Crete during World War II . 35°15′24″N 25°37′42″E  /  35.25667°N 25.62833°E  / 35.25667; 25.62833 Iron Age The Iron Age ( c.  1200  – c.  550 BC )

3920-676: 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

4018-504: The Bronze Age. In Central and Western Europe, the Roman conquests of the 1st century BC serve as marking the end of the Iron Age. The Germanic Iron Age of Scandinavia is considered to end c.  AD 800 , with the beginning of the Viking Age . The three-age method of Stone, Bronze, and Iron Ages was first used for the archaeology of Europe during the first half of the 19th century, and by

4116-455: The Indian subcontinent began prior to the 3rd millennium BC. Archaeological sites in India, such as Malhar, Dadupur, Raja Nala Ka Tila, Lahuradewa, Kosambi and Jhusi , Allahabad in present-day Uttar Pradesh show iron implements in the period 1800–1200 BC. As the evidence from the sites Raja Nala ka tila, Malhar suggest the use of Iron in c. 1800/1700 BC. The extensive use of iron smelting

4214-752: The Indian subcontinent suggest Indianization of Southeast Asia beginning in the 4th to 2nd centuries BC during the late Iron Age. In Philippines and Vietnam , the Sa Huynh culture showed evidence of an extensive trade network. Sa Huynh beads were made from glass, carnelian, agate, olivine, zircon, gold and garnet; most of these materials were not local to the region and were most likely imported. Han-dynasty-style bronze mirrors were also found in Sa Huynh sites. Conversely, Sa Huynh produced ear ornaments have been found in archaeological sites in Central Thailand, as well as

4312-612: The Late Bronze Age continued into the Early Iron Age. Thus, there is a sociocultural continuity during this transitional period. In Iran, the earliest actual iron artifacts were unknown until the 9th century BC. For Iran, the best studied archaeological site during this time period is Teppe Hasanlu . In the Mesopotamian states of Sumer , Akkad and Assyria , the initial use of iron reaches far back, to perhaps 3000 BC. One of

4410-570: The Late Bronze Age. As part of the Late Bronze Age-Early Iron Age, the Bronze Age collapse saw the slow, comparatively continuous spread of iron-working technology in the region. It was long believed that the success of the Hittite Empire during the Late Bronze Age had been based on the advantages entailed by the "monopoly" on ironworking at the time. Accordingly, the invading Sea Peoples would have been responsible for spreading

4508-595: The Romans, though ironworking remained the dominant technology until recent times. Elsewhere it may last until the early centuries AD, and either Christianization or a new conquest during the Migration Period . Iron working was introduced to Europe during the late 11th century BC, probably from the Caucasus , and slowly spread northwards and westwards over the succeeding 500 years. The Iron Age did not start when iron first appeared in Europe but it began to replace bronze in

4606-586: The archaeological record. For instance, in China, written history started before iron smelting began, so the term is used infrequently for the archaeology of China. For the Ancient Near East, the establishment of the Achaemenid Empire c.  550 BC is used traditionally and still usually as an end date; later dates are considered historical according to the record by Herodotus despite considerable written records now being known from well back into

4704-452: 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 )

4802-590: The beginning of the Western Han dynasty . Yoon proposes that iron was first introduced to chiefdoms located along North Korean river valleys that flow into the Yellow Sea such as the Cheongcheon and Taedong Rivers. Iron production quickly followed during the 2nd century BC, and iron implements came to be used by farmers by the 1st century in southern Korea. The earliest known cast-iron axes in southern Korea are found in

4900-482: The capabilities of Neolithic kilns , which date back to 6000 BC and were able to produce temperatures greater than 900 °C (1,650 °F). In addition to specially designed furnaces, ancient iron production required the development of complex procedures for the removal of impurities, the regulation of the admixture of carbon, and the invention of hot-working to achieve a useful balance of hardness and strength in steel. The use of steel has also been regulated by

4998-745: The centers of origin were located in West Africa , Central Africa , and East Africa ; consequently, as these origin centers are located within inner Africa, these archaeometallurgical developments are thus native African technologies. Iron metallurgical development occurred 2631–2458 BC at Lejja, in Nigeria, 2136–1921 BC at Obui, in Central Africa Republic, 1895–1370 BC at Tchire Ouma 147, in Niger, and 1297–1051 BC at Dekpassanware, in Togo.

Therefore, in China prehistory had given way to history periodized by ruling dynasties by the start of iron use, so "Iron Age" is not used typically to describe a period of Chinese history. Iron metallurgy reached

5194-420: The earliest smelted iron artifacts known is a dagger with an iron blade found in a Hattic tomb in Anatolia , dating from 2500 BC. The widespread use of iron weapons which replaced bronze weapons rapidly disseminated throughout the Near East (North Africa, southwest Asia ) by the beginning of the 1st millennium BC. The development of iron smelting was once attributed to the Hittites of Anatolia during

5292-434: The economics of the metallurgical advancements. The earliest tentative evidence for iron-making is a small number of iron fragments with the appropriate amounts of carbon admixture found in the Proto-Hittite layers at Kaman-Kalehöyük in modern-day Turkey, dated to 2200–2000 BC. Akanuma (2008) concludes that "The combination of carbon dating, archaeological context, and archaeometallurgical examination indicates that it

5390-505: The emergence of the Iron Age proper by several centuries. Iron was being used in Mundigak to manufacture some items in the 3rd millennium BC such as a small copper/bronze bell with an iron clapper, a copper/bronze rod with two iron decorative buttons, and a copper/bronze mirror handle with a decorative iron button. Artefacts including small knives and blades have been discovered in the Indian state of Telangana which have been dated between 2400 BC and 1800 BC. The history of metallurgy in

5488-520: The end of the Bronze Age . The Iron Age in Europe is often considered as a part of the Bronze Age collapse in the ancient Near East . Anthony Snodgrass suggests that a shortage of tin and trade disruptions in the Mediterranean about 1300 BC forced metalworkers to seek an alternative to bronze. Many bronze implements were recycled into weapons during that time, and more widespread use of iron resulted in improved steel-making technology and lower costs. When tin became readily available again, iron

5586-438: The excavation of Ugarit. A dagger with an iron blade found in Tutankhamun's tomb , 13th century BC, was examined recently and found to be of meteoric origin. In Europe, the Iron Age is the last stage of prehistoric Europe and the first of the protohistoric periods, which initially means descriptions of a particular area by Greek and Roman writers. For much of Europe, the period came to an abrupt local end after conquest by

5684-401: The first millennium BC. In Southern India (present-day Mysore ) iron appeared as early as 12th to 11th centuries BC; these developments were too early for any significant close contact with the northwest of the country. The Indian Upanishads mention metallurgy. and the Indian Mauryan period saw advances in metallurgy. As early as 300 BC, certainly by 200 AD, high-quality steel

5782-424: The forms and character of the ornamentation of the northern European weapons resemble in some respects Roman arms, while in other respects they are peculiar and evidently representative of northern art. Citânia de Briteiros , located in Guimarães , Portugal, is one of the examples of archaeological sites of the Iron Age. This settlement (fortified villages) covered an area of 3.8 hectares (9.4 acres), and served as

5880-545: 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

5978-523: 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.

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

6174-446: The knowledge through that region. The idea of such a "Hittite monopoly" has been examined more thoroughly and no longer represents a scholarly consensus. While there are some iron objects from Bronze Age Anatolia, the number is comparable to iron objects found in Egypt and other places of the same time period; and only a small number of these objects are weapons. Dates are approximate; consult particular article for details. Iron metal

The Early Iron Age in the Caucasus area is divided conventionally into two periods, Early Iron I, dated to about 1100 BC, and the Early Iron II phase from the tenth to ninth centuries BC. Many of the material culture traditions of

Distinguishing characteristics of the Yayoi period include the appearance of new pottery styles and the start of intensive rice agriculture in paddy fields. Yayoi culture flourished in a geographic area from southern Kyūshū to northern Honshū . The Kofun and

As an archaeological era, it was first introduced to Scandinavia by Christian Jürgensen Thomsen during the 1830s. By the 1860s, it was embraced as a useful division of the "earliest history of mankind" in general and began to be applied in Assyriology . The development of

6664-824: 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

6762-410: 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:

6860-446: 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,

6958-587: 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

7056-521: The nearby Djenné-Djenno culture of the Niger Valley in Mali shows evidence of iron production from c. 250 BC. Iron technology across much of sub-Saharan Africa has an African origin dating to before 2000 BC. These findings confirm the independent invention of iron smelting in sub-Saharan Africa. Modern archaeological evidence identifies the start of large-scale global iron production about 1200 BC, marking

7154-534: The now-conventional periodization in the archaeology of the Ancient Near East was developed during the 1920s and 1930s. Meteoric iron, a natural iron–nickel alloy , was used by various ancient peoples thousands of years before the Iron Age. The earliest-known meteoric iron artifacts are nine small beads dated to 3200 BC , which were found in burials at Gerzeh in Lower Egypt , having been shaped by careful hammering. The characteristic of an Iron Age culture

7252-518: 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

7350-424: 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

7448-566: The preparation of tools and weapons. It did not happen at the same time throughout Europe; local cultural developments played a role in the transition to the Iron Age. For example, the Iron Age of Prehistoric Ireland begins about 500 BC (when the Greek Iron Age had already ended) and finishes about 400 AD. The widespread use of the technology of iron was implemented in Europe simultaneously with Asia. The prehistoric Iron Age in Central Europe

7546-452: 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

7644-454: 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

7742-623: 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

7840-471: 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

7938-614: The subsequent Asuka periods are sometimes referred to collectively as the Yamato period ; The word kofun is Japanese for the type of burial mounds dating from that era. Iron objects were introduced to the Korean peninsula through trade with chiefdoms and state-level societies in the Yellow Sea area during the 4th century BC, just at the end of the Warring States Period but prior to

8036-469: 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

8134-439: 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

8232-419: 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

8330-690: 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

8428-705: 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

8526-481: Was attributed to Seth, the spirit of evil who according to Egyptian tradition governed the central deserts of Africa. In the Black Pyramid of Abusir , dating before 2000 BC, Gaston Maspero found some pieces of iron. In the funeral text of Pepi I , the metal is mentioned. A sword bearing the name of pharaoh Merneptah as well as a battle axe with an iron blade and gold-decorated bronze shaft were both found in

8624-400: Was cheaper, stronger and lighter, and forged iron implements superseded cast bronze tools permanently. In Central and Western Europe, the Iron Age lasted from c.  800 BC to c.  1 BC , beginning in pre-Roman Iron Age Northern Europe in c.  600 BC , and reaching Northern Scandinavian Europe about c.  500 BC . The Iron Age in the Ancient Near East

8722-555: Was excavated in 1935 by Spyridon Marinatos , who published it. Three statuettes made of bronze sheets hammered over moulding cores ( sphyrelaton ) "in the early orientalizing style of the late eighth century" (Boardman) were found in the precincts of the Temple of Apollo Delphinios; they are now at the Archaeological Museum of Herakleion . They probably depict Apollo and Artemis and their mother Leto and together are known as

8820-520: 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

8918-468: 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

9016-508: Was not included among the thirty Cretan cities that signed a pact with the Attalid king of Pergamum , Eumenes II , in 183 BCE. The site has little to offer to the casual tourist. South of the agora is one of the earliest free-standing Greek temples ; it dates from the Geometric period ( c.  750  BCE ). The Delphinion , as it is called, was dedicated to Apollo Delphinios . It

9114-424: 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

9212-476: 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

9310-551: Was produced in southern India, by what would later be called the crucible technique . In this system, high-purity wrought iron, charcoal, and glass were mixed in a crucible and heated until the iron melted and absorbed the carbon. The protohistoric Early Iron Age in Sri Lanka lasted from 1000 BC to 600 BC. Radiocarbon evidence has been collected from Anuradhapura and Aligala shelter in Sigiriya . The Anuradhapura settlement

9408-458: Was somewhat delayed, and Northern Europe was not reached until about the start of the 5th century BC (500 BC). The Iron Age in India is stated as beginning with the ironworking Painted Grey Ware culture , dating from the 15th century BC , through to the reign of Ashoka in the 3rd century BC . The term "Iron Age" in the archaeology of South, East, and Southeast Asia is more recent and less common than for Western Eurasia. Africa did not have

9506-587: 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

9604-518: 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 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
