Ferrous metallurgy is the metallurgy of iron and its alloys . The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt , were made from meteoritic iron-nickel . It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in the region from Greece to India, The use of wrought iron (worked iron) was known by the 1st millennium BC, and its spread defined the Iron Age . During the medieval period, smiths in Europe found a way of producing wrought iron from cast iron , in this context known as pig iron , using finery forges . All these processes required charcoal as fuel .
78-629: The Oregon Iron Company was an iron smelting company located in what is now Lake Oswego, Oregon . The company was established in 1865, and in 1867, became the first company west of the Rocky Mountains in the United States to smelt iron. The company failed after a few years, but was reorganized as the Oswego Iron Company in 1878, and again as the Oregon Iron and Steel Company in 1883. With
156-451: A bead from the 5th millennium BC found in Iran and spear tips and ornaments from ancient Egypt and Sumer around 4000 BC. These early uses appear to have been largely ceremonial or decorative. Meteoric iron is very rare, and the metal was probably very expensive, perhaps more expensive than gold . The early Hittites are known to have bartered iron (meteoric or smelted) for silver , at
234-518: A commercial scale, having been displaced by the functionally equivalent mild or low-carbon steel. Iron was extracted from iron–nickel alloys , which comprise about 6% of all meteorites that fall on the Earth . That source can often be identified with certainty because of the unique crystalline features ( Widmanstätten patterns ) of that material, which are preserved when the metal is worked cold or at low temperature. Those artifacts include, for example,
312-967: A complex process of "pre-heating" allowing temperatures inside a furnace to reach 1300 to 1400 °C. Iron and copper working spread southward through the continent, reaching the Cape around AD 200. The widespread use of iron revolutionized the Bantu -speaking farming communities who adopted it, driving out and absorbing the rock tool using hunter-gatherer societies they encountered as they expanded to farm wider areas of savanna . The technologically superior Bantu-speakers spread across southern Africa and became wealthy and powerful, producing iron for tools and weapons in large, industrial quantities. The earliest records of bloomery-type furnaces in East Africa are discoveries of smelted iron and carbon in Nubia that date back between
390-562: A crucible and heated until the iron melted and absorbed the carbon. Iron chain was used in Indian suspension bridges as early as the 4th century. Wootz steel was produced in India and Sri Lanka from around 300 BC. Wootz steel is famous from Classical Antiquity for its durability and ability to hold an edge. When asked by King Porus to select a gift, Alexander is said to have chosen, over gold or silver , thirty pounds of steel. Wootz steel
468-545: A few, probably ornamental, bronze weapons. During the Han dynasty (202 BC–220 AD), the government established ironworking as a state monopoly, repealed during the latter half of the dynasty and returned to private entrepreneurship , and built a series of large blast furnaces in Henan province, each capable of producing several tons of iron per day. By this time, Chinese metallurgists had discovered how to fine molten pig iron, stirring it in
546-603: A lack of investment and never started production of the steel rails Reed expected; Reed lost half a million dollars in the venture. Reed and Ladd also operated a hobby farm of more than 8,000-acre (32 km ), on which they raised livestock and held harness races, in the area where Reedville, Oregon now stands, with Reed as namesake. On November 7, 1895, Simeon Reed died while in California at his retirement home, "Carmelita" , in Pasadena . His estate, worth millions of dollars,
624-421: A new era of greatly increased use of iron and steel that some contemporaries described as a new "Iron Age". In the late 1850s Henry Bessemer invented a new steelmaking process which involved blowing air through molten pig-iron to burn off carbon, and so producing mild steel. This and other 19th-century and later steel-making processes have displaced wrought iron . Today, wrought iron is no longer produced on
702-640: A rate of 40 times the iron's weight, with Assyria in the first centuries of the second millennium BC . Meteoric iron was also fashioned into tools in the Arctic when the Thule people of Greenland began making harpoons , knives, ulus and other edged tools from pieces of the Cape York meteorite . Typically pea-size bits of metal were cold-hammered into disks and fitted to a bone handle. These artifacts were also used as trade goods with other Arctic peoples: tools made from
780-594: A reduction furnace and blacksmith workshop; with earliest dates of 896–773 BC and 907–796 BC respectively. Similarly, smelting in bloomery-type furnaces appear in the Nok culture of central Nigeria by about 550 BC and possibly a few centuries earlier. There is also evidence that carbon steel was made in Western Tanzania by the ancestors of the Haya people as early as 2,300 to 2,000 years ago (about 300 BC or soon after) by
858-502: A result of the forging process. There was no fundamental change in the technology of iron production in Europe for many centuries. European metal workers continued to produce iron in bloomeries. However, the Medieval period brought two developments—the use of water power in the bloomery process in various places (outlined above), and the first European production in cast iron. Sometime in

#1732870115546936-558: A seven-year restoration of the furnace was completed. Of the two first pigs smelted in 1867, one is displayed in the Oregon Historical Society and one remains in place as a street marker at the northwest corner of Ladd and Durham streets in Lake Oswego. The crucible from the second furnace, which was dismantled and sold for scrap in 1926, is still intact in Lake Oswego's Roehr Park. History of ferrous metallurgy By
1014-509: A short time, he relocated to Portland and became friends with William S. Ladd , a local merchant. In 1854, Amanda sailed to San Francisco to reunite with Reed, and accompanied Caroline Ames Elliott, Ladd's sweetheart who he married in San Francisco. In 1855, Reed became a clerk for Ladd, and in 1859 he became a partner in the company, which was then known as Ladd, Reed, & Co. In May 1860, Reed, Jacob Kamm , and John C. Ainsworth founded
1092-582: A shortage of bronze or tin in the Early Iron Age. Bronze objects remained abundant, and these objects have the same percentage of tin as those from the Late Bronze Age. The history of ferrous metallurgy in the Indian subcontinent began in the 2nd millennium BC. Archaeological sites in the Gangetic plains have yielded iron implements dated between 1800 and 1200 BC. By the early 13th century BC, iron smelting
1170-558: Is a knife blade from the Catacomb culture in present-day Ukraine, dated to c. 2500 BC. During most of the Middle and Late Bronze Age in Europe, iron was present, though scarce. It was used for personal ornaments and small knives, for repairs on bronzes, and for bimetallic items. Early smelted iron finds from central Europe include an iron knife or sickle from Ganovce in Slovakia, possibly dating from
1248-648: Is not known, partly because of the difficulty of distinguishing metal extracted from nickel-containing ores from hot-worked meteoritic iron. The archaeological evidence seems to point to the Middle East area, during the Bronze Age in the 3rd millennium BC. However, wrought iron artifacts remained a rarity until the 12th century BC. The Iron Age is conventionally defined by the widespread replacement of bronze weapons and tools with those of iron and steel. That transition happened at different times in different places, as
1326-632: Is rather brittle and unsuitable for striking implements. It can be decarburized to steel or wrought iron by heating it in air for several days. In China, these iron working methods spread northward, and by 300 BC, iron was the material of choice throughout China for most tools and weapons. A mass grave in Hebei province, dated to the early 3rd century BC, contains several soldiers buried with their weapons and other equipment. The artifacts recovered from this grave are variously made of wrought iron, cast iron, malleabilized cast iron, and quench-hardened steel, with only
1404-569: Is some uncertainty, some archaeologists believe that iron metallurgy was developed independently in sub-Saharan Africa (possibly in West Africa). Inhabitants of Termit, in eastern Niger , smelted iron around 1500 BC. In the region of the Aïr Mountains in Niger there are also signs of independent copper smelting between 2500 and 1500 BC. The process was not in a developed state, indicating smelting
1482-505: The Furness district of England, powered bloomeries were in use into the beginning of the 18th century, and near Garstang until about 1770. The Catalan Forge was a variety of powered bloomery. Bloomeries with hot blast were used in upstate New York in the mid-19th century. The preferred method of iron production in Europe until the development of the puddling process in 1783–84. Cast iron development lagged in Europe because wrought iron
1560-634: The La Tène culture saw a significant increase in iron production, with iron metallurgy also becoming common in southern Scandinavia. North of Sweden saw steel manufacturing dating back to around 0 AD through the eastern-western migration of hunter-gatherers in the Cap of the North . The spread of ironworking in Central and Western Europe is associated with Celtic expansion. Celtic smiths produced steel from circa 800 BC as part of
1638-567: The Oregon Steam Navigation Company , a conglomerate of several river shipping companies plying the Columbia and Willamette rivers. Reed held 128 shares in the company, which even during the economic depression of 1873 produced $ 300,000 in dividends. Reed was also vice president of the firm. He built a mansion at First and Harrison streets in 1868, where the other wealthy residents were also constructing large homes. In April 1880,

#17328701155461716-417: The iron oxide from the ore to metallic iron. The bloomery, however, was not hot enough to melt the iron, so the metal collected in the bottom of the furnace as a spongy mass, or bloom . Workers then repeatedly beat and folded it to force out the molten slag . This laborious, time-consuming process produced wrought iron , a malleable but fairly soft alloy. Concurrent with the transition from bronze to iron
1794-740: The oregrounds iron favoured by English steelmakers. A variation on this was the German forge . This became the main method of producing bar iron in Sweden. Simeon Gannett Reed Simeon Gannett Reed (April 23, 1830 – November 7, 1895) was an American businessman and entrepreneur in Oregon . A native of Massachusetts , he made a fortune primarily in the transportation sector in association with William S. Ladd . Reedville, Oregon , and Reed College in Portland, Oregon are named after Reed. Simeon Gannett Reed
1872-575: The 10th century BC iron became the prevailing metal in use. In the Carpathian Basin there is a significant increase in iron finds dating from the 10th century BC onwards, with some finds possibly dating as early as the 12th century BC. Iron swords have been found in central Europe dating from the 10th century BC; however, the Iron Age began in earnest with the Hallstatt culture from 800 BC. From 500 BC
1950-615: The 18th century BC, an iron ring from Vorwohlde in Germany dating from circa the 15th century BC, and an iron chisel from Heegermühle in Germany dating from circa 1000 BC. Iron metallurgy began to be practised in Scandinavia during the later Bronze Age from at least the 9th century BC. In the 11th century BC iron swords replaced bronze swords in Southern Europe, especially in Greece, and in
2028-620: The 4th century BC southern India had started exporting wootz steel , with a carbon content between pig iron and wrought iron, to ancient China, Africa, the Middle East, and Europe. Archaeological evidence of cast iron appears in 5th-century BC China. New methods of producing it by carburizing bars of iron in the cementation process were devised in the 17th century. During the Industrial Revolution , new methods of producing bar iron by substituting coke for charcoal emerged, and these were later applied to produce steel , ushering in
2106-675: The 7th and 6th centuries BC, particularly in Meroe where there are known to have been ancient bloomeries that produced metal tools for the Nubians and Kushites and produced surplus for their economy. Iron technology was further advanced by several inventions in medieval Islam , during the Islamic Golden Age . By the 11th century, every province throughout the Muslim world had these industrial mills in operation, from Islamic Spain and North Africa in
2184-407: The 9th century BC. Cast iron was used in ancient China for warfare, agriculture and architecture. Around 500 BC, metalworkers in the southern state of Wu achieved a temperature of 1130 °C. At this temperature, iron combines with 4.3% carbon and melts. The liquid iron can be cast into molds , a method far less laborious than individually forging each piece of iron from a bloom. Cast iron
2262-680: The Barnum and Richardson Company furnace in Lime Rock, Connecticut . The furnace was designed by British stonemason Richard Martin and was completed in 1867. Meanwhile, a dam was built on Sucker Creek to harness water for power, forests were cleared to be turned into charcoal to feed the furnace, and limestone , used during iron smelting to remove impurities, was quarried from the San Juan Islands in Washington Territory , and shipped and unloaded at
2340-695: The Cape York meteorite have been found in archaeological sites more than 1,000 miles (1,600 km) distant. When the American polar explorer Robert Peary shipped the largest piece of the meteorite to the American Museum of Natural History in New York City in 1897, it still weighed over 33 tons . Another example of a late use of meteoric iron is an adze from around 1000 AD found in Sweden . Native iron in
2418-597: The Eastern Mediterranean and destroyed the Hittite empire at the end of the Late Bronze Age, were responsible for spreading the knowledge through that region. This theory is no longer held in the mainstream of scholarship, since there is no archaeological evidence of the alleged Hittite monopoly. While there are some iron objects from Bronze Age Anatolia, the number is comparable to iron objects found in Egypt and other places of

2496-591: The Middle East. One theory suggests that metallurgy was introduced through Central Asia. In 2008, two iron fragments were excavated at the Mogou site , in Gansu . They have been dated to the 14th century BC, belonging to the period of Siwa culture , suggesting an independent Chinese origin. One of the fragments was made of bloomery iron rather than meteoritic iron. The earliest iron artifacts made from bloomeries in China date to end of
2574-590: The Oregon Iron Company. Ladd, who served as president, and the others hoped to make Oswego the " Pittsburgh of the West", believing that having a local source of iron would help their other businesses, which included the Oregon Central Railroad and the Oregon Steam Navigation Company . To oversee construction of a charcoal-fired blast furnace , the company recruited George Wilbur. He modeled his design on
2652-588: The Oregon Steam Navigation Company merged with the companies of Henry Villard and Ben Holladay to form the Oregon Railway and Navigation Company . This created a single transportation conglomerate encompassing river shipping, stagecoach , and railroad ventures. Reed focused his energy now on meeting the demand for steel he anticipated due to Villard's Northern Pacific railroad. But Reed's Oregon Iron and Steel Company at Oswego suffered
2730-478: The addition of a larger furnace, the last incarnation of the company prospered, reaching peak production in 1890. By 1894, however, pressure from cheaper imported iron combined with the effects of the Panic of 1893 forced the company to close its smelter. The company continued to operate a pipe foundry until 1928, and until the early 1960s, existed as a land management company, selling its real estate holdings which expanded
2808-759: 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 BCE – 2458 BCE at Lejja, in Nigeria, 2136 BCE – 1921 BCE at Obui, in Central Africa Republic, 1895 BCE – 1370 BCE at Tchire Ouma 147, in Niger, and 1297 BCE – 1051 BCE at Dekpassanware, in Togo. Though there
2886-520: The city of Lake Oswego. The discovery of iron ore near the settlement of Oswego in the hills south of Portland is credited to Morton M. McCarver (who had served as speaker of the Provisional Legislature of Oregon ) in 1862. McCarver's brown hematite ore was tested and found to be of excellent quality, containing from 56 to 75% metal. In addition, the ore lay near the surface and the Oswego bed
2964-484: The company also incurred massive debt, and with the market price for iron remaining low, the company was sold in 1880 to another group of Portland financiers led by Simeon Gannett Reed and railroad baron Henry Villard . In 1882, the company was reincorporated as the Oregon Iron and Steel Company with Reed as its president and William M. Ladd, son of Oregon Iron Company founder William S. Ladd, as its vice president. With
3042-511: The company docks on the adjacent Willamette River . On August 24, 1867, the Oregon Iron Company became the first company in the United States to smelt pig iron west of the Rocky Mountains. The first pigs were given to J. C. Trullinger, who owned the townsite of Oswego. From 1867 to 1869, the company smelted nearly 2,400 short tons (2,200 t) of iron. Ladd's group soon found their business expertise in other areas did not apply as well to
3120-528: The company still found itself with thousands of acres of land that could be developed. William M. Ladd, who had succeeded Reed as President of Oregon Iron and Steel and his father as President of Ladd & Tilton Bank, formed the Ladd Estate Company to manage these real estate assets. The newly formed Ladd Estate Company converted the depressed company town into a prestigious suburb complete with country club, golf course, polo field, and even worked to rename
3198-526: The earliest smelted iron artifacts, a dagger with an iron blade found in a Hattic tomb in Anatolia , dated from 2500 BC. About 1500 BC, increasing numbers of non-meteoritic, smelted iron objects appeared in Mesopotamia , Anatolia and Egypt. Nineteen meteoric iron objects were found in the tomb of Egyptian ruler Tutankhamun , who died in 1323 BC, including an iron dagger with a golden hilt, an Eye of Horus ,

3276-422: The elder Ladd, Villard, and Darius Ogden Mills also providing financing, the company built a new smelter north of the original furnace with five times its capacity, 50 short tons (45 t). The new iron works opened in 1888, and production boomed. The company employed 300 men and Oswego's population soared, as hotels, churches, saloons, and an opera house were built to support the town. A railroad line to Portland
3354-496: The final closure of the furnace in 1894. The company continued to operate a pipe foundry on the site of the new furnace until 1928. The Willamette Meteorite was discovered on Oregon Iron & Steel property. An attempt was made to steal it. In 1917, the Pacific Coast Steel Company bought the furnace as a precautionary measure to insure a supply of pig iron during a present scarcity. Despite its lack of industry,
3432-591: The first western account of the use of iron in India. The Indian mythological texts, the Upanishads , have mentions of weaving, pottery and metallurgy, as well. The Romans had high regard for the excellence of steel from India in the time of the Gupta Empire . Perhaps as early as 500 BC, although certainly by 200 AD, high-quality steel was produced in southern India by the crucible technique . In this system, high-purity wrought iron, charcoal, and glass were mixed in
3510-535: The harsh-sounding Sucker Lake to Oswego Lake . The company existed as a shell until 1960, when in its final act, it deeded its powerhouse and dams to lake shareholders. The original blast furnace still stands in Lake Oswego's George Rogers Park along the Willamette River , the only extant iron furnace west of the Rocky Mountains. It was placed on the National Register of Historic Places in 1974. In 2010,
3588-472: The iron industry. Their lack of experience, coupled with a dispute over water rights, caused the company to close in 1869. After a brief respite in which they filled an order for iron wheels for the Central Pacific Railroad from 1874 to 1876, the company closed for good in 1878 and the assets were sold off at a sheriff's auction. The purchasers were led by Ernest Crichton and L. B. Seeley, experienced furnace managers from Ohio's Hanging Rock iron region. Under
3666-413: The kilns used for pottery ) and cast into molds, smelted iron requires hot-working and can be melted only in specially designed furnaces. Iron is a common impurity in copper ores and iron ore was sometimes used as a flux , thus it is not surprising that humans mastered the technology of smelted iron only after several millennia of bronze metallurgy . The place and time for the discovery of iron smelting
3744-426: The medieval period, water power was applied to the bloomery process. It is possible that this was at the Cistercian Abbey of Clairvaux as early as 1135, but it was certainly in use in early 13th century France and Sweden. In England , the first clear documentary evidence for this is the accounts of a forge of the Bishop of Durham , near Bedburn in 1408, but that was certainly not the first such ironworks. In
3822-408: The metallic state occurs rarely as small inclusions in certain basalt rocks. Besides meteoritic iron, Thule people of Greenland have used native iron from the Disko region. Iron smelting—the extraction of usable metal from oxidized iron ores—is more difficult than tin and copper smelting. While these metals and their alloys can be cold-worked or melted in relatively simple furnaces (such as
3900-456: The modern Bessemer process that utilized partial decarbonization via repeated forging under a cold blast. By the 11th century, there was a large amount of deforestation in China due to the iron industry's demands for charcoal. By this time however, the Chinese had learned to use bituminous coke to replace charcoal, and with this switch in resources many acres of prime timberland in China were spared. The earliest smelted iron object from Europe
3978-431: The mummy's head-stand and sixteen models of an artisan's tools. An Ancient Egyptian 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 the excavation of Ugarit . Although iron objects dating from the Bronze Age have been found across the Eastern Mediterranean, bronzework appears to have greatly predominated during this period. As

#17328701155464056-483: The new name of the Oswego Iron Company, the company made a number of significant improvements: they purchased the Oswego townsite along with large tracts of forest, settled the water rights issue, remodeled the furnace, opened several new mines, constructed several homes for its workers, and built a narrow gauge railroad for hauling the ore. From 1877 to 1881, the Oswego Iron Company produced 18,500 short tons (16,800 t) of iron. However, to finance these improvements,
4134-443: The open air until it lost its carbon and could be hammered (wrought). In modern Mandarin- Chinese , this process is now called chao , literally stir frying . Pig iron is known as 'raw iron', while wrought iron is known as 'cooked iron'. By the 1st century BC, Chinese metallurgists had found that wrought iron and cast iron could be melted together to yield an alloy of intermediate carbon content, that is, steel. According to legend,
4212-483: The period from 900 to 1750. This was produced using the crucible steel method, based on the earlier Indian wootz steel . This process was adopted in the Middle East using locally produced steels. The exact process remains unknown, but it allowed carbides to precipitate out as micro particles arranged in sheets or bands within the body of a blade. Carbides are far harder than the surrounding low carbon steel, so swordsmiths could produce an edge that cut hard materials with
4290-409: The piece into steel , an alloy of iron and iron carbides , with an inner core of less brittle iron. The development of iron smelting was traditionally attributed to the Hittites of Anatolia of the Late Bronze Age . It was believed that they maintained a monopoly on iron working, and that their empire had been based on that advantage. According to that theory, the ancient Sea Peoples , who invaded
4368-401: The practice followed the Mongols across Russia to these sites, but there is no clear proof of this hypothesis, and it would certainly not explain the pre-Mongol datings of many of these iron-production centres. In any event, by the late 14th century, a market for cast iron goods began to form, as a demand developed for cast iron cannonballs. An alternative method of decarburising pig iron

A team of researchers based at the Technical University of Dresden that uses X-rays and electron microscopy to examine Damascus steel discovered the presence of cementite nanowires and carbon nanotubes . Peter Paufler, a member of the Dresden team, says that these nanostructures give Damascus steel its distinctive properties and are

During the Han dynasty, the Chinese were also the first to apply hydraulic power (i.e. a waterwheel ) in working the bellows of the blast furnace. This was recorded in the year 31 AD, as an innovation by the Chinese mechanical engineer and politician Du Shi , Prefect of Nanyang. Although Du Shi

By the 1st century BC, Noric steel was famous for its quality and sought-after by the Roman military . The annual iron output of the Roman Empire is estimated at 84,750 t . Archaeometallurgical scientific knowledge and technological development originated in numerous centers of Africa;

A more recent theory claims that the development of iron technology was driven by the disruption of the copper and tin trade routes, due to the collapse of the empires at the end of the Late Bronze Age. These metals, especially tin, were not widely available and metal workers had to transport them over long distances, whereas iron ores were widely available. However, no known archaeological evidence suggests
4758-405: The sword of Liu Bang , the first Han emperor, was made in this fashion. Some texts of the era mention "harmonizing the hard and the soft" in the context of ironworking; the phrase may refer to this process. The ancient city of Wan ( Nanyang ) from the Han period forward was a major center of the iron and steel industry. Along with their original methods of forging steel, the Chinese had also adopted

#17328701155464836-399: The technology spread, iron came to replace bronze as the dominant metal used for tools and weapons across the Eastern Mediterranean (the Levant , Cyprus , Greece , Crete , Anatolia and Egypt). Iron was originally smelted in bloomeries , furnaces where bellows were used to force air through a pile of iron ore and burning charcoal . The carbon monoxide produced by the charcoal reduced
4914-455: The technology spread. Mesopotamia was fully into the Iron Age by 900 BC. Although Egypt produced iron artifacts, bronze remained dominant until its conquest by Assyria in 663 BC. The Iron Age began in India about 1200 BC, in Central Europe about 800 BC, and in China about 300 BC. Around 500 BC, the Nubians , who had learned from the Assyrians the use of iron and were expelled from Egypt, became major manufacturers and exporters of iron. One of

However, half the company's resources were dedicated to making charcoal from wood. The availability of cheaper imported coke -fired iron, the overall reduction in demand for iron as railroad expansion slowed, and the economic effects of the Panic of 1893 , all combined to hasten

Since the site also featured vast forests that could be turned into charcoal to feed the smelting furnaces, and ready access to water for power, the potential of a successful mining operation was easily recognized. In 1865, a group of financiers in Portland, which included former Portland mayors William S. Ladd and Henry Failing , as well as Portland Gas Light Company founders Herman C. Leonard and John Green, incorporated an iron smelting company which they named

Ladd) provided the lands on which the college stands today, and almost all of Reed's estate
5460-505: Was mass-produced. Steel was produced in Sri Lanka from 300 BC by furnaces blown by the monsoon winds . The furnaces were dug into the crests of hills, and the wind was diverted into the air vents by long trenches. This arrangement created a zone of high pressure at the entrance, and a zone of low pressure at the top of the furnace. The flow is believed to have allowed higher temperatures than bellows-driven furnaces could produce, resulting in better-quality iron. Steel made in Sri Lanka
5538-437: Was not foreign. It became mature about 1500 BC. Archaeological sites containing iron smelting furnaces and slag have also been excavated at sites in the Nsukka region of southeast Nigeria in what is now Igboland : dating to 2000 BC at the site of Lejja (Eze-Uzomaka 2009) and to 750 BC and at the site of Opi (Holl 2009). The site of Gbabiri (in the Central African Republic) has yielded evidence of iron metallurgy, from
5616-546: Was originally a complex alloy with iron as its main component together with various trace elements . Recent studies have suggested that its qualities may have been due to the formation of carbon nanotubes in the metal. According to Will Durant , the technology passed to the Persians and from them to Arabs who spread it through the Middle East. In the 16th century, the Dutch carried the technology from South India to Europe, where it
5694-565: Was practiced on a large scale in India. In Southern India (present day Mysore ) iron was in use 12th to 11th centuries BC. The technology of iron metallurgy advanced in the politically stable Maurya period and during a period of peaceful settlements in the 1st millennium BC. Iron artifacts such as spikes , knives , daggers , arrow -heads, bowls , spoons , saucepans , axes , chisels , tongs , door fittings, etc., dated from 600 to 200 BC, have been discovered at several archaeological sites of India. The Greek historian Herodotus wrote
5772-451: Was the finery forge , which seems to have been devised in the region around Namur in the 15th century. By the end of that century, this Walloon process spread to the Pay de Bray on the eastern boundary of Normandy , and then to England, where it became the main method of making wrought iron by 1600. It was introduced to Sweden by Louis de Geer in the early 17th century and was used to make
5850-648: Was the desired product and the intermediate step of producing cast iron involved an expensive blast furnace and further refining of pig iron to cast iron, which then required a labor and capital intensive conversion to wrought iron. Through a good portion of the Middle Ages, in Western Europe, iron was still being made by the working of iron blooms into wrought iron. Some of the earliest casting of iron in Europe occurred in Sweden, in two sites, Lapphyttan and Vinarhyttan, between 1150 and 1350. Some scholars have speculated
5928-410: Was the discovery of carburization , the process of adding carbon to wrought iron. While the iron bloom contained some carbon, the subsequent hot-working oxidized most of it. Smiths in the Middle East discovered that wrought iron could be turned into a much harder product by heating the finished piece in a bed of charcoal, and then quenching it in water or oil. This procedure turned the outer layers of
6006-550: Was the first to apply water power to bellows in metallurgy, the first drawn and printed illustration of its operation with water power appeared in 1313 AD, in the Yuan dynasty era text called the Nong Shu . In the 11th century, there is evidence of the production of steel in Song China using two techniques: a "berganesque" method that produced inferior, heterogeneous steel and a precursor to
6084-668: Was traded extensively within the region and in the Islamic world . One of the world's foremost metallurgical curiosities is an iron pillar located in the Qutb complex in Delhi . The pillar is made of wrought iron (98% Fe ), is almost seven meters high and weighs more than six tonnes. The pillar was erected by Chandragupta II Vikramaditya and has withstood 1,600 years of exposure to heavy rains with relatively little corrosion . Historians debate whether bloomery-based ironworking ever spread to China from
