James Vetch (1789–1869) was a Scottish army officer and civil engineer. A veteran of the Peninsular War in the Royal Engineers , in later life he took on a wide range of engineering work, including mining in Mexico. He was a Fellow of the Royal Society , and a writer of reports for Parliament and the Admiralty.
101-551: The third son of Robert Vetch of Caponflat, Haddington, East Lothian , and his wife Agnes Sharp, he was born at Haddington on 13 May 1789. Educated at Haddington and Edinburgh, he entered the Royal Military College, Great Marlow , and in 1805 was transferred to the Royal Military Academy, Woolwich . He was employed on the trigonometrical survey at Oakingham , Berkshire (1806), until he received
202-607: A market town . Today, Haddington is a small town with a population of about 10,000 people, but during the High Middle Ages it was the fourth-biggest town in Scotland (after Aberdeen , Roxburgh and Edinburgh). In the middle of the town is the Haddington Town House , completed in 1745 based on a plan by William Adam . When first built, it contained markets on the ground floor, and an assembly hall on
303-524: A bar, expelling slag in the process. During the Middle Ages , water-power was applied to the process, probably initially for powering bellows, and only later to hammers for forging the blooms. However, while it is certain that water-power was used, the details remain uncertain. That was the culmination of the direct process of ironmaking. It survived in Spain and southern France as Catalan Forges to
404-582: A carbon content of less than 0.008 wt% . Bar iron is a generic term sometimes used to distinguish it from cast iron. It is the equivalent of an ingot of cast metal, in a convenient form for handling, storage, shipping and further working into a finished product. The bars were the usual product of the finery forge , but not necessarily made by that process: Wrought iron is a form of commercial iron containing less than 0.10% of carbon, less than 0.25% of impurities total of sulfur, phosphorus, silicon and manganese, and less than 2% slag by weight. Wrought iron
505-478: A commission as second lieutenant in the Royal Engineers on 1 July 1807. He was promoted to lieutenant on 1 March 1808. After serving for three years, partly at Chatham and partly at Plymouth, he was sent in 1810 to Spain, and joined the division of Sir Thomas Graham at the blockade of Cadiz . He took part in the battle of Barrosa on 5 March 1811, and was made the bearer of despatches to Gibraltar. Vetch
606-460: A double track. Passengers from Haddington were required to alight at Longniddry and change trains in order to travel to Edinburgh. The Haddington branch line and station were damaged during the flood of 1948 and though both passenger and freight services were reinstated, British Rail opted to remove rail services to the public due to competition from bus services and dwindling passenger numbers. Passenger services ended on 29 December 1949. The use of
707-470: A final product. Sometimes European ironworks would skip the shingling process completely and roll the puddle balls. The only drawback to that is that the edges of the rough bars were not as well compressed. When the rough bar was reheated, the edges might separate and be lost into the furnace. The bloom was passed through rollers and to produce bars. The bars of wrought iron were of poor quality, called muck bars or puddle bars. To improve their quality,
808-576: A hardware shop, cookware shop and several gift shops alongside several pubs, restaurants and cafés. Nationwide retailers with a presence in Haddington include: Tesco , Home Bargains , Boots , Aldi and Co-op Food . Besides retail and administration, the town is also home to various law firms and has industrial capacity in the works beside the Tyne at the Victoria Bridge (PureMalt), and around
909-463: A high silky luster and fibrous appearance. Wrought iron lacks the carbon content necessary for hardening through heat treatment , but in areas where steel was uncommon or unknown, tools were sometimes cold-worked (hence cold iron ) to harden them. An advantage of its low carbon content is its excellent weldability. Furthermore, sheet wrought iron cannot bend as much as steel sheet metal when cold worked. Wrought iron can be melted and cast; however,
1010-701: A large tract of country. His papers and maps on the subject were presented after his death to the topographical department of the War Office . He presented a collection of Mexican antiquities to the British Museum and wrote a paper about them. From 1839 the project of a ship canal between the Mediterranean and Red Seas occupied Vetch's attention. In 1843 he published a work on it which ran through several editions and attracted much public attention. The government, and especially Lord Palmerston , opposed
1111-434: A low scale to supply the steel to the artisan swordmakers. Osmond iron consisted of balls of wrought iron, produced by melting pig iron and catching the droplets on a staff, which was spun in front of a blast of air so as to expose as much of it as possible to the air and oxidise its carbon content. The resultant ball was often forged into bar iron in a hammer mill. In the 15th century, the blast furnace spread into what
SECTION 10
#17327868803471212-449: A lower melting point than iron or steel. Cast and especially pig iron have excess slag which must be at least partially removed to produce quality wrought iron. At foundries it was common to blend scrap wrought iron with cast iron to improve the physical properties of castings. For several years after the introduction of Bessemer and open hearth steel, there were different opinions as to what differentiated iron from steel; some believed it
1313-459: A modest amount of wrought iron was refined into steel , which was used mainly to produce swords , cutlery , chisels , axes , and other edged tools, as well as springs and files. The demand for wrought iron reached its peak in the 1860s, being in high demand for ironclad warships and railway use. However, as properties such as brittleness of mild steel improved with better ferrous metallurgy and as steel became less costly to make thanks to
1414-564: A number of notable buildings but the Abbey of St Mary and 16th Century town defences have left little to see on the ground. They are being researched by Haddington's History Society. St Martin's Kirk also remains one of the towns oldest and most prominent buildings. Amisfield House was located east of Haddington, south of the River Tyne. Designed by architect Isaac Ware and built of Garvald red freestone for Colonel Francis Charteris , it
1515-603: A number of patented processes for that, which are referred to today as potting and stamping . The earliest were developed by John Wood of Wednesbury and his brother Charles Wood of Low Mill at Egremont , patented in 1763. Another was developed for the Coalbrookdale Company by the Cranage brothers . Another important one was that of John Wright and Joseph Jesson of West Bromwich . A number of processes for making wrought iron without charcoal were devised as
1616-410: A process for manufacturing wrought iron quickly and economically. It involved taking molten steel from a Bessemer converter and pouring it into cooler liquid slag. The temperature of the steel is about 1500 °C and the liquid slag is maintained at approximately 1200 °C. The molten steel contains a large amount of dissolved gases so when the liquid steel hit the cooler surfaces of the liquid slag

Haddington, East Lothian The Royal Burgh of Haddington ( Scots : Haidintoun , Scottish Gaelic : Baile Adainn ) is a town in East Lothian , Scotland. It is the main administrative, cultural and geographical centre for East Lothian. It lies about 17 miles (27 kilometres) east of Edinburgh . The name Haddington
1818-410: A refinery where raw coal was used to remove silicon and convert carbon within the raw material, found in the form of graphite, to a combination with iron called cementite. In the fully developed process (of Hall), this metal was placed into the hearth of the puddling furnace where it was melted. The hearth was lined with oxidizing agents such as haematite and iron oxide. The mixture was subjected to
1919-481: A single hearth for all stages. The introduction of coke for use in the blast furnace by Abraham Darby in 1709 (or perhaps others a little earlier) initially had little effect on wrought iron production. Only in the 1750s was coke pig iron used on any significant scale as the feedstock of finery forges. However, charcoal continued to be the fuel for the finery. From the late 1750s, ironmasters began to develop processes for making bar iron without charcoal. There were
2020-412: A strong current of air and stirred with long bars, called puddling bars or rabbles, through working doors. The air, the stirring, and the "boiling" action of the metal helped the oxidizing agents to oxidize the impurities and carbon out of the pig iron. As the impurities oxidize, they formed a molten slag or drifted off as gas, while the remaining iron solidified into spongy wrought iron that floated to
2121-432: A very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4.5%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure . Wrought iron is tough, malleable, ductile , corrosion resistant, and easily forge welded , but is more difficult to weld electrically. Before

#17327868803472222-424: Is redshort or hot short if it contains sulfur in excess quantity. It has sufficient tenacity when cold, but cracks when bent or finished at a red heat. Hot short iron was considered unmarketable. Cold short iron, also known as coldshear , colshire , contains excessive phosphorus. It is very brittle when cold and cracks if bent. It may, however, be worked at high temperature. Historically, coldshort iron
2323-483: Is Anglo-Saxon , dating from the sixth or seventh century AD when the area was incorporated into the kingdom of Bernicia . The town, like the rest of the Lothian region, was ceded by King Edgar of England and became part of Scotland in the tenth century. Haddington received Burgh status, one of the earliest to do so, during the reign of David I (1124–1153), giving it trading rights which encouraged its growth into
2424-489: Is a mainly fourteenth-century castle about 5 miles (8 kilometres) east of Haddington. This castle, which has a fine riverside setting, belonged to the Hepburn family during the most important centuries of its existence. Since 1926, it has been the subject of a state-sponsored guardianship agreement, which is now under the auspices of Historic Scotland. It is open to the public without charge at all reasonable times. Haddington
2525-414: Is a more important measure of the quality of wrought iron. In tensile testing, the best irons are able to undergo considerable elongation before failure. Higher tensile wrought iron is brittle. Because of the large number of boiler explosions on steamboats in the early 1800s, the U.S. Congress passed legislation in 1830 which approved funds for correcting the problem. The treasury awarded a $ 1500 contract to
2626-520: Is an archaic past participle of the verb "to work", and so "wrought iron" literally means "worked iron". Wrought iron is a general term for the commodity, but is also used more specifically for finished iron goods, as manufactured by a blacksmith . It was used in that narrower sense in British Customs records, such manufactured iron was subject to a higher rate of duty than what might be called "unwrought" iron. Cast iron , unlike wrought iron,
2727-435: Is brittle and cannot be worked either hot or cold. In the 17th, 18th, and 19th centuries, wrought iron went by a wide variety of terms according to its form, origin, or quality. While the bloomery process produced wrought iron directly from ore, cast iron or pig iron were the starting materials used in the finery forge and puddling furnace . Pig iron and cast iron have higher carbon content than wrought iron, but have
2828-491: Is deceptive. Most of the manganese, sulfur, phosphorus, and silicon in the wrought iron are incorporated into the slag fibers, making wrought iron purer than plain carbon steel. Amongst its other properties, wrought iron becomes soft at red heat and can be easily forged and forge welded . It can be used to form temporary magnets , but it cannot be magnetized permanently, and is ductile , malleable , and tough . For most purposes, ductility rather than tensile strength
2929-467: Is highly refined, with a small amount of silicate slag forged out into fibers. It comprises around 99.4% iron by mass. The presence of slag can be beneficial for blacksmithing operations, such as forge welding, since the silicate inclusions act as a flux and give the material its unique, fibrous structure. The silicate filaments in the slag also protect the iron from corrosion and diminish the effect of fatigue caused by shock and vibration. Historically,

At the end of March 2012, the town's library relocated to the John Gray Centre in Lodge Street, an extensively reconstructed and restored complex of historic buildings including
3131-407: Is no longer manufactured commercially. Wrought iron was originally produced by a variety of smelting processes, all described today as "bloomeries". Different forms of bloomery were used at different places and times. The bloomery was charged with charcoal and iron ore and then lit. Air was blown in through a tuyere to heat the bloomery to a temperature somewhat below the melting point of iron. In

3232-450: Is no longer produced on a commercial scale. Many products described as wrought iron, such as guard rails , garden furniture , and gates are made of mild steel. They are described as "wrought iron" only because they have been made to resemble objects which in the past were wrought (worked) by hand by a blacksmith (although many decorative iron objects, including fences and gates, were often cast rather than wrought). The word "wrought"
3333-628: Is now Belgium where it was improved. From there, it spread via the Pays de Bray on the boundary of Normandy and then to the Weald in England. With it, the finery forge spread. Those remelted the pig iron and (in effect) burnt out the carbon, producing a bloom, which was then forged into bar iron. If rod iron was required, a slitting mill was used. The finery process existed in two slightly different forms. In Great Britain, France, and parts of Sweden, only

Many items, before they came to be made of mild steel , were produced from wrought iron, including rivets , nails , wire , chains , rails , railway couplings , water and steam pipes , nuts , bolts , horseshoes , handrails , wagon tires, straps for timber roof trusses , and ornamental ironwork , among many other things. Wrought iron
3838-481: The Industrial Revolution began during the latter half of the 18th century. The most successful of those was puddling, using a puddling furnace (a variety of the reverberatory furnace ), which was invented by Henry Cort in 1784. It was later improved by others including Joseph Hall , who was the first to add iron oxide to the charge. In that type of furnace, the metal does not come into contact with

He also gave his services to the Anglo-Mexican Mining Association, promoted by John Diston Powles and later to the United-Mexico Mining Association, a rival. He returned to England in 1829, but again went to Mexico after his marriage in 1832, and remained there until 1835. During his period in Mexico he constructed roads for
4040-609: The Walloon process was used. That employed two different hearths, a finery hearth for finishing the iron and a chafery hearth for reheating it in the course of drawing the bloom out into a bar. The finery always burnt charcoal, but the chafery could be fired with mineral coal , since its impurities would not harm the iron when it was in the solid state. On the other hand, the German process, used in Germany, Russia, and most of Sweden used

The nearest rail station is at Drem, four miles (six kilometres) to the north, which is served by regular Edinburgh to North Berwick trains. Haddington was once served by its own railway branch line which carried passengers for over a century from 1846 to 1949. There have been proposals to reopen or extend a railway line to Haddington to ease road congestion, but nothing has come to fruition in regards to this. The Haddington railway line
4545-701: The 1960s, the price of steel production was dropping due to recycling, and even using the Aston process, wrought iron production was labor-intensive. It has been estimated that the production of wrought iron is approximately twice as expensive as that of low-carbon steel. In the United States, the last plant closed in 1969. The last in the world was the Atlas Forge of Thomas Walmsley and Sons in Bolton , Great Britain, which closed in 1973. Its 1860s-era equipment

Johnson and Benjamin Reeves conducted strength tests on boiler iron using a tester they had built in 1832 based on a design by Lagerhjelm in Sweden. Because of misunderstandings about tensile strength and ductility, their work did little to reduce failures. The importance of ductility was recognized by some very early in
4848-542: The Middle Ages, iron was produced by the direct reduction of ore in manually operated bloomeries , although water power had begun to be employed by 1104. The raw material produced by all indirect processes is pig iron. It has a high carbon content and as a consequence, it is brittle and cannot be used to make hardware. The osmond process was the first of the indirect processes, developed by 1203, but bloomery production continued in many places. The process depended on

The present building (built with red sandstone from nearby Garvald ) was started in 1375 (an earlier St Mary's Church having been destroyed by the English in 1356), and consecrated in 1410, despite building work not being finished until 1487. The church was partially destroyed during the 1548-49 Siege of Haddington that followed the Rough Wooing of Henry VIII , and on

Thus the nave became the church and the choir and transepts were left ruined until the whole church was restored in the 1970s. The Lammermuir pipe organ was built in 1990. A set of eight bells hung for full change ringing was installed for the Millennium . Haddington War Memorial stands at the west entrance to the churchyard. Hailes Castle
5151-451: The bars were cut up, piled and tied together by wires, a process known as faggoting or piling. They were then reheated to a welding state, forge welded, and rolled again into bars. The process could be repeated several times to produce wrought iron of desired quality. Wrought iron that has been rolled multiple times is called merchant bar or merchant iron. The advantage of puddling was that it used coal, not charcoal as fuel. However, that

5757-498: The development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag.

There is no engineering advantage to melting and casting wrought iron, as compared to using cast iron or steel, both of which are cheaper. Due to the variations in iron ore origin and iron manufacture, wrought iron can be inferior or superior in corrosion resistance, compared to other iron alloys. There are many mechanisms behind its corrosion resistance. Chilton and Evans found that nickel enrichment bands reduce corrosion. They also found that in puddled, forged, and piled iron,

For instance, a galvanic zinc finish applied to wrought iron is approximately 25–40% thicker than the same finish on steel. In Table 1, the chemical composition of wrought iron is compared to that of pig iron and carbon steel . Although it appears that wrought iron and plain carbon steel have similar chemical compositions, that
7373-507: The same year he proposed an extended water supply for the London metropolis, and in 1850 designed a system of drainage for Southwark. In 1858–9 he was a member of the royal commission on harbours of refuge, of which Admiral Sir James Hope was chairman. Vetch retired from the Admiralty in 1863; his office of conservator was then abolished and the duties transferred to the Board of Trade . He
7474-517: The seal and on the coat of arms of Haddington. John Martine wrote Reminiscences of the royal burgh of Haddington and old East Lothian agriculturists in 1883. On 5 September 1618 a debt collector from Edinburgh, Thomas Allan, was attacked by Isobel Addington and 60 or 80 other women who beat him and then dragged him by the feet out of her house. People who have received the Freedom of the burgh of Haddington include: There are several churches in
7575-648: The seventeenth century, and it is now the seat of the Duke of Hamilton and Brandon . The Parish Church of St Mary's is today part of the Church of Scotland , but includes an Episcopalian chapel, the Lauderdale Aisle , containing the mausoleum of the Maitland Earls of Lauderdale . It is the longest parish church in Scotland and is in regular use for worship and musical events. It is directly adjacent to
7676-531: The site of the old station (Lemac), and various smaller industrial units and garages. Haddington is also home to the offices of the local newspaper the East Lothian Courier . There is a farmers' market held on the last Saturday of the month in Court Street. The town centre largely retains its historic street plan with Court Street, High Street, Market Street and Hardgate defining the edges of
7777-454: The southern edge of the town centre and Letham Mains is in the Letham estate on the western outskirts . Prior to October 2012, Haddington Infant School was two separate buildings; the main building (built in 1897) and the annex (built in 1965) was located at Victoria Road/Meadowpark and the old St. Mary's Primary School was located at Tynebank Road. Following the discovery of structural defects at
7878-517: The station in the 1940s (isolated as it then was at the western extremity of Haddington), the town has since expanded significantly. Between 1951 and 1981, the population of the town grew by 54%. It remains to be seen whether further expansion of the town will lead to a reinstatement of Haddington's railway line, since there are congestion issues on both the East Coast Main Line and at Edinburgh Waverley railway station . An account of
7979-680: The summer house, walled garden, ice house, chapel, and gates. The world's earliest surviving records of a lodge of free gardeners come from Haddington, in 1676. Lennoxlove House , a historic thirteenth-century house and estate, lies 1 ⁄ 2 mile (800 metres) south of Haddington. Built by the Giffards of Yester , it was originally named Lethington . It was once home to the Maitland family, notably Sir Richard Maitland , and his son William Maitland of Lethington , Secretary of State to Mary, Queen of Scots '. The Maitlands left Lennoxlove in
8080-465: The top of the puddle and was fished out of the melt as puddle balls, using puddle bars. There was still some slag left in the puddle balls, so while they were still hot they would be shingled to remove the remaining slag and cinder. That was achieved by forging the balls under a hammer, or by squeezing the bloom in a machine. The material obtained at the end of shingling is known as bloom. The blooms are not useful in that form, so they were rolled into
8181-516: The town's former granary. In addition to the lending library the Centre comprises East Lothian Council's Historical Archives, Local History Collections and Reading Room, a new museum of East Lothian (with a temporary exhibition gallery), a computer suite and community room. The Centre is named after a local minister whose bequest of books and money in 1717 gave the town one of the earliest community libraries in Scotland. Haddington sits 1 km south of
8282-682: The town's relatively unaltered medieval plan and significant survival of historic buildings was recognised as early as the 1950s, with Haddington subject to an Improvement Scheme, Scotland's earliest, which saw many period properties rehabilitated by the Town Council (under the leadership of Frank Tindall as Director of Planning) and a pioneering town colour scheme developed, resulting in the distinctive and colourful townscape seen today. Some comprehensive redevelopment did occur, chiefly around Newton Port and Hardgate to allow for widening of these narrow streets to improve motor traffic flow. This included
8383-767: The town. These include: Kenny MacAskill , Depute Leader of the Alba Party has served as the MP for East Lothian since 2019 . Paul McLennan of the Scottish National Party has served as the MSP for East Lothian since 2021 . There are four councillors for Haddington and Lammermuir. Haddington has three state primary schools; the first being Haddington primary school,the second being St. Mary's RC Primary School and third being Letham Mains primary school. Both HPS and Saint Mary’s are located adjacent to Neilson Park at
8484-560: The working-over of the metal spread out copper, nickel, and tin impurities that produce electrochemical conditions that slow down corrosion. The slag inclusions have been shown to disperse corrosion to an even film, enabling the iron to resist pitting. Another study has shown that slag inclusions are pathways to corrosion. Other studies show that sulfur in the wrought iron decreases corrosion resistance, while phosphorus increases corrosion resistance. Chloride ions also decrease wrought iron's corrosion resistance. Wrought iron may be welded in
8585-467: Was a branch from the East Coast Main Line at Longniddry and terminated at Haddington railway station and freight depot in the area between West Road and Hospital Road. The line was 4 + 13 ⁄ 16 miles (7.7 kilometres) in length and had stations at Coatyburn Siding and Laverocklaw Siding before terminating in Haddington. The line was opened on 22 June 1846. The branch had only a single track, though bridges and embankments were built to allow for
8686-479: Was adopted (1865 on). Iron remained dominant for structural applications until the 1880s, because of problems with brittle steel, caused by introduced nitrogen, high carbon, excess phosphorus, or excessive temperature during or too-rapid rolling. By 1890 steel had largely replaced iron for structural applications. Sheet iron (Armco 99.97% pure iron) had good properties for use in appliances, being well-suited for enamelling and welding, and being rust-resistant. In
8787-533: Was appointed consulting engineer to the admiralty; in 1847 he was appointed a member of the new harbour conservancy board at the admiralty, the other members being John Washington and Charles Bethune of the Royal Navy Washington was withdrawn from the board in 1849, and in 1853 Vetch was appointed sole conservator of harbours. In 1849 he was appointed one of the metropolitan commissioners of sewers, an honorary office which he held for four years. In
8888-542: Was appointed one of the three commissioners to carry changes in tenancies, John Douglas Cook acting as secretary. In 1844, 1845, and 1846 Vetch was examined by the Commissioners Upon the Subject of Harbours of Refuges, and at their request wrote a report on wrought iron frameworks in the construction of piers and breakwaters. In 1845 he reported on designs for a harbour of refuge at Dover. In July 1846 Vetch
8989-469: Was author of: Reports were published by Vetch between 1847 and 1859 on the following harbours: Ramsgate, the Tyne, Cork, Wexford, the Isle of Man, Holyhead, Port Patrick, and Donaghadee, Galway, Portsmouth, Table Bay, Port Natal, Point de Galle. Feeling the want of a good map of Mexico, Vetch accumulated astronomical and barometrical observations while there, measured several short base-lines, and triangulated
9090-490: Was considered sufficient for nails . Phosphorus is not necessarily detrimental to iron. Ancient Near Eastern smiths did not add lime to their furnaces. The absence of calcium oxide in the slag, and the deliberate use of wood with high phosphorus content during the smelting, induces a higher phosphorus content (typically <0.3%) than in modern iron (<0.02–0.03%). Analysis of the Iron Pillar of Delhi gives 0.11% in
9191-470: Was described in The Buildings of Scotland as "the most important building of the orthodox Palladian school in Scotland." John Henderson built the walled garden in 1783, and the castellated stable block in 1785. The park in front of the house, possibly landscaped by James Bowie, is today entirely ploughed. A victim of dry rot, the house was demolished in 1928. All that remains of Amisfield today are
9292-579: Was drawn up in May 1681, and major capital invested in new machinery, but the New Mills had mixed fortunes, inevitably affected by the lack of protectionism for Scottish manufactured cloth. The Scots Courant reported in 1712 that New Mills was to be "rouped" (auctioned). The property was sold on 16 February 1713 and the machinery and plant on 20 March. The lands of New Mills were purchased by Colonel Francis Charteris and he changed their name to Amisfield. As
9393-637: Was elected a fellow of the Royal Geographical Society in 1830, an associate of the Institution of Civil Engineers in 1839, a member of the Société Française de Statistique Universelle in 1852, and was a member of other learned bodies. He died on 7 December 1869, and was buried in a family vault (plot no.5277) on the western side of Highgate cemetery . The vault is overgrown with a broken and illegible monument. Vetch
9494-515: Was hypothesized that the type of iron had been rejected for conversion to steel but excelled when tested for drawing ability. During the Han dynasty (202 BC – 220 AD), new iron smelting processes led to the manufacture of new wrought iron implements for use in agriculture, such as the multi-tube seed drill and iron plough . In addition to accidental lumps of low-carbon wrought iron produced by excessive injected air in ancient Chinese cupola furnaces . The ancient Chinese created wrought iron by using
9595-477: Was moved to the Blists Hill site of Ironbridge Gorge Museum for preservation. Some wrought iron is still being produced for heritage restoration purposes, but only by recycling scrap. The slag inclusions, or stringers , in wrought iron give it properties not found in other forms of ferrous metal. There are approximately 250,000 inclusions per square inch. A fresh fracture shows a clear bluish color with
9696-445: Was not the intention. However, the design of a bloomery made it difficult to reach the melting point of iron and also prevented the concentration of carbon monoxide from becoming high. After smelting was complete, the bloom was removed, and the process could then be started again. It was thus a batch process, rather than a continuous one such as a blast furnace. The bloom had to be forged mechanically to consolidate it and shape it into
9797-541: Was of little advantage in Sweden, which lacked coal. Gustaf Ekman observed charcoal fineries at Ulverston , which were quite different from any in Sweden. After his return to Sweden in the 1830s, he experimented and developed a process similar to puddling but used firewood and charcoal, which was widely adopted in the Bergslagen in the following decades. In 1925, James Aston of the United States developed
9898-520: Was passed by the Parliament of Scotland to encourage the production of fine cloth, and in 1645 an amendment went through stating that the masters and workers of manufactories would be exempt from military service. As a result of this, more factories were established; these included the New Mills. This factory suffered during the Civil War with the loss of its cloth to General Monck . A new charter
9999-461: Was probably born in Haddington and Knox Academy , the local high school, is named after him. Haddington is located predominantly on the left bank of the River Tyne , and was once famous for its mills. It developed into the fourth-largest town in Scotland during the High Middle Ages , and later was at the centre of the mid-eighteenth century Scottish Agricultural Revolution . In 1641, an Act
10100-473: Was the chemical composition and others that it was whether the iron heated sufficiently to melt and "fuse". Fusion eventually became generally accepted as relatively more important than composition below a given low carbon concentration. Another difference is that steel can be hardened by heat treating . Historically, wrought iron was known as "commercially pure iron"; however, it no longer qualifies because current standards for commercially pure iron require
10201-541: Was then sent to the Barbary Coast , and went on from Tangier to Tetuan to report on the capabilities of the country to furnish engineering supplies. In March 1812 Vetch left Cadiz for Elvas , sailing up the Guadiana River with a company of sappers and miners to take part in the siege of Badajos . On the evening of 6 April, when the final assault took place, he made a lodgment with three hundred men in
