93-502: The Joseph Willis House is a historic colonial house located at 28 Worcester Street in Taunton, Massachusetts . Built in 1688, it is the city's oldest surviving building, and one of the oldest in the state. The Joseph Willis House is located in a rural residential area of western Taunton, on the southwestern side of the junction of Worcester Street and Alfred Lord Boulevard. It is a 2 + 1 ⁄ 2 -story, timber-framed structure, with

186-529: A state of emergency . It is estimated that if the dam had failed, the Mill River would have inundated the downtown area with up to 6 feet (1.8 m) of water. In response, Massachusetts Governor Mitt Romney ordered an immediate inspection of high-risk dams throughout the Commonwealth. In 2010, the historic Taunton City Hall was severely damaged in an arson fire. City government operated out of

279-524: 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

372-582: 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

465-471: A female householder with no husband present, and 35.3% were non-families. Of all households 28.2% were made up of individuals, and 9.9% had someone living alone who was 65 years of age or older. The average household size was 2.60 and the average family size was 3.09. In the city, the population was spread out, with 24.9% under the age of 18, 8.0% from 18 to 24, 33.2% from 25 to 44, 21.0% from 45 to 64, and 12.9% who were 65 years of age or older. The median age

558-470: 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,

651-463: 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,

744-434: 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

837-449: 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

930-459: 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

1023-581: A museum of regional objects, houses a research library specializing in local history and genealogy, and hosts arts and cultural events throughout the year. Taunton has four art galleries: Taunton Art Association (John Baradas Gallery), Hughes/Donahue Gallery, Art Euphoric, and the Trescott Street Gallery. The Taunton Art Association was founded in 1973 but had it roots in the Girl's Club in the early 1960s. Hughes/Donahue Gallery, founded in 2007,

1116-564: A number of historic commercial blocks along Main Street, Taunton Green and Broadway, built during the period from about 1840 to 1920. Many large homes built by the wealthy industrialists and merchants of the late 19th and early 20th century line Route 44 , both east (Dean Street) and west (Winthrop Street) of the city center, while a majority of the city is occupied by more modest wood-framed single and multi-family homes, many over 100 years old. Modern single-family subdivisions , built mostly since

1209-603: 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

1302-707: A portion of the film Shutter Island starring Leonardo DiCaprio in Taunton on location at the Whittenton Mills Complex. Surrogates , starring Bruce Willis , was partly filmed in the city, at the old Paul Dever school. As the seat of Bristol County , Taunton is home to many of the county's courthouses and administrative offices. These include the Taunton District Court, Bristol County Register of Deeds, and historic Bristol County Superior Courthouse. Wrought iron Before

1395-410: 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

1488-610: A publicly owned electric utility. Today, TMLP provides electric service to 34,000 customers in Taunton, Berkley, Raynham, and sections of Dighton, Lakeville and Bridgewater. TMLP is governed by a three-member Board of Commissioners, which is elected by the citizens of Taunton. In the late 19th century, Taunton was a stop on the national bicycle racing circuit. In 1897, the one-mile (1.6 km) open event made news when third-place finisher W. E. Becker brutally attacked second-place winner Major Taylor , knocking him unconscious for fifteen minutes. Built in 1942, U.S. Army Camp Myles Standish

1581-410: 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

1674-425: A side gable roof that slopes down to the first floor in the rear, giving the house a saltbox profile. Its main facade is four bays wide, with somewhat even placement of sash windows on the second floor, and asymmetrical placement on the first. The entrance is in the second bay from the left, and is framed by pilasters and a transom window. A large chimney projects through the roof at a slightly off-center position that

1767-481: 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

1860-412: 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

1953-424: 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

2046-487: Is a local community gallery serving local Taunton artists, as well as the surrounding areas of Southeastern Massachusetts and the cities of Providence, Rhode Island, and Washington, DC. Art Euphoric, founded in 2008, has both visual and craft exhibits and sales. The Trescott Street Gallery, founded in 2012, is primarily a visual-arts gallery but also exhibits crafts. In March 2008, Hollywood director Martin Scorsese filmed

2139-414: 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

2232-695: Is also home to almost the entirety of Massasoit State Park in East Taunton, and a large portion of the Hockomock Swamp Wildlife Management Area in North Taunton. As of the census of 2000, there were 55,874 people, 22,045 households, and 14,473 families residing in the city. The population density was 1,200.1 inhabitants per square mile (463.4/km ). There were 22,908 housing units at an average density of 491.5 per square mile (189.8/km ). The racial makeup of

2325-520: 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,

2418-435: 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

2511-491: 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

2604-467: 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,

2697-652: Is land and 1.7 square miles (4.4 km ), or 3.53%, is water. It is the third-largest city by area in Massachusetts, after Boston and Barnstable . Taunton has one major river, the Taunton River , along with its tributaries, including the Mill River and the Three Mile River . The highest point in the city is near its southwest corner, with an elevation of 207 feet (63 m) above sea level. Prospect Hill, rising over Lake Sabbatia north of

2790-408: Is located further north at the intersection of Broadway and Washington Street, known as Saint Mary's Square. In the 1880s Jewish immigrants from Russia began to move to the town, and Congregation Agudath Achim was founded in 1911. The congregation is now an independent progressive synagogue. Taunton's economy has historically been based on silversmithing and shipbuilding . Reed & Barton produced

2883-407: 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

2976-450: 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"

3069-628: 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

3162-442: Is roughly behind the entrance. The house's first owner, Joseph Willis was a native of Bridgewater who was granted land in Taunton as a favor for his military service during King Philip's War . He moved to the area in 1670, and built this house in 1688. It was extended by two ells in the 19th century, and its interior was remodeled in the 20th century. It is believed to be the oldest building in Taunton at its original location. It

3255-546: Is the mayor of Taunton. Founded in 1637 by members of the Plymouth Colony , Taunton is one of the oldest towns in the United States. Taunton is also known as the "Silver City", as it was a historic center of the silver industry beginning in the 19th century when companies such as Reed & Barton, F. B. Rogers , Poole Silver, and others produced fine-quality silver goods in the city. Since December 1914,

3348-714: Is visible from many surrounding areas. It was added to the National Register of Historic Places in 1978. Currently, the Courthouse Complex is undergoing a major expansion and renovation program. Other significant buildings in the city include some fine stone churches, including the First Parish Church (1830), the Pilgrim Congregational Church (1851) and St. Mary's Church (1868) on Broadway. Downtown Taunton has

3441-648: The 1996 Summer Olympics medals and silverware used exclusively for the White House . Also, the city produced the anchor for the USS Constitution . The nearby town of Raynham produced the anchor for the Civil War-era ironclad USS Monitor . Today, the city's economy has emphases on semiconductor , silicon, and electronics manufacturing. It is home to the corporate headquarters of many leading corporations in various industries. Currently,

3534-555: The Bessemer process and the Siemens–Martin process , the use of wrought iron declined. 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

3627-481: 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

3720-585: The Poole Silver Company , and the Taunton Silverplate Company . In the 19th century, Taunton was also the center of an important iron-making industry, utilizing much bog iron from the numerous swamps in the surrounding area. The iron industry in Taunton produced a variety of goods including stoves (Weir Stove Company/Glenwood), tacks (Field Tack Company) and machinery. One of the more successful companies during this period

3813-609: 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 historic Taunton City Hall is located adjacent to Church Green . One of New England's oldest historical societies, the Old Colony Historical Society is located on picturesque Church Green. Founded in 1853, the Society maintains

4371-638: 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

The other form of iron, cast iron , was in use in China since ancient times but was not introduced into Western Europe until the 15th century; even then, due to its brittleness, it could be used for only a limited number of purposes. Throughout much of

4557-575: The Franklin Institute to conduct a study. As part of the study, Walter R. 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

4650-542: 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 city is served by a central public library, the Taunton Public Library , which opened in 1903 and has undergone several expansions and renovations since that time. Also of note is the Old Colony Historical Society , which archives

4929-535: The Taunton area was called Cohannet, Tetiquet or Titiquet. The English founders of Taunton purchased the land from the Nemasket Natives in 1637 as part of the Tetiquet Purchase and the remaining native families were relocated to the praying town of Ponkapoag in present-day Canton, Massachusetts . Elizabeth Poole , contrary to local folklore, did not take part in the town purchase but

5022-451: 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

5115-544: The city and region's past. The city is home to two state parks operated by the Massachusetts Department of Conservation and Recreation : Massasoit State Park in East Taunton and Watson Pond State Park in the north part of the city. The city of Taunton has a wide array of architecture ranging from the colonial period to modern times. There are numerous pre-Revolutionary War private homes within

5208-429: The city is trying to attract biotechnology research companies to its industrial parks. Silver City Galleria was a large shopping mall in Taunton catering to the local city and to the neighboring towns and cities of Raynham, Berkley, Rehoboth, Dighton, New Bedford, Fall River, Norton, Easton, Assonet, Acushnet, Bridgewater, Lakeville, Middleboro, and Freetown. It was open for 28 years, closing on February 29, 2020 and

The city is bordered by Norton to the northwest, Easton to the north, Raynham to the northeast, Middleborough to the east, Lakeville to the southeast, Berkley and Dighton to the south, and Rehoboth to the west. City neighborhoods include the Bird Lanes, Clearview Estates, East Taunton , Elliot's Corner, Herring Run Estates, Linden Estates, Matthews Landing, North Taunton , Oakland , Pine Crest Estates, Pine Hill Estates, Wades Corner, Weir Village , Westville, Whittenton, Whittenton Junction, Britannia Village or Britanniaville, Willis Lake Village and Woodward Estates. Taunton

5394-555: The city of Taunton has provided a large annual light display each December on Taunton Green , giving it the additional nickname of the Christmas City . The original boundaries of Taunton included the land now occupied by many surrounding towns, including Norton , Easton , Mansfield , Dighton , Raynham , Berkley , and Lakeville . Possession of the latter is still noted by the naming of Taunton Hill in Assonet . Taunton

5487-507: The city, including Roman Catholic, Protestant, and Jewish congregations. The First Parish Church, now a Unitarian Universalist church, located at Church Green at the east end of downtown, was founded in 1637, before the Town of Taunton was even established. The current church dates from 1830. The Pilgrim Congregational Church on Broadway was formed in 1821, its current church built in 1851. The city's oldest Roman Catholic parish, St. Mary's Church,

With its tall copper dome, the Superior Courthouse

5673-413: The course of the smelt, slag would melt and run out, and carbon monoxide from the charcoal would reduce the ore to iron, which formed a spongy mass (called a "bloom") containing iron and also molten silicate minerals (slag) from the ore. The iron remained in the solid state. If the bloomery were allowed to become hot enough to melt the iron, carbon would dissolve into it and form pig or cast iron, but that

5766-498: 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. The modern functional equivalent of wrought iron is mild steel , also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardened by heating and quenching. Wrought iron

5859-593: The development of the blast furnace, of which medieval examples have been discovered at Lapphyttan , Sweden and in Germany . The bloomery and osmond processes were gradually replaced from the 15th century by finery processes, of which there were two versions, the German and Walloon. They were in turn replaced from the late 18th century by puddling , with certain variants such as the Swedish Lancashire process . Those, too, are now obsolete, and wrought iron

In 2012 Taunton became the target location for a Wampanoag casino complex which was embroiled in conflict by competing regional bands of the Wampanoag over territory claims. The proposed casino resort complex location is adjacent to a local elementary school and

6138-432: The fuel, and so is not contaminated by its impurities. The heat of the combustion products passes over the surface of the puddle and the roof of the furnace reverberates (reflects) the heat onto the metal puddle on the fire bridge of the furnace. Unless the raw material used is white cast iron, the pig iron or other raw product of the puddling first had to be refined into refined iron , or finers metal. That would be done in

6231-401: The gases were liberated. The molten steel then froze to yield a spongy mass having a temperature of about 1370 °C. The spongy mass would then be finished by being shingled and rolled as described under puddling (above). Three to four tons could be converted per batch with the method. Steel began to replace iron for railroad rails as soon as the Bessemer process for its manufacture

6324-430: The iron. The included slag in wrought iron also imparts corrosion resistance. Antique music wire , manufactured at a time when mass-produced carbon-steels were available, was found to have low carbon and high phosphorus; iron with high phosphorus content, normally causing brittleness when worked cold, was easily drawn into music wires. Although at the time phosphorus was not an easily identified component of iron, it

In Japan the last of the old tatara bloomeries used in production of traditional tamahagane steel, mainly used in swordmaking, was extinguished only in 1925, though in the late 20th century the production resumed on

6510-666: The product is no longer wrought iron, since the slag stringers characteristic of wrought iron disappear on melting, so the product resembles impure, cast, Bessemer steel. 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,

On June 10, 2012, the City of Taunton dedicated the Taunton Global War on Terrorism War Memorial on Church Green . Taunton is home to a General Dynamics Mission Systems factory, which develops military communications equipment. According to the United States Census Bureau , the city has a total area of 48.4 square miles (125.4 km ), of which 46.4 square miles (120.1 km )

6696-531: The same manner as mild steel, but the presence of oxide or inclusions will give defective results. The material has a rough surface, so it can hold platings and coatings better than smooth steel. 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

6789-465: 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

6882-560: 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

6975-446: Was Luso-American . The biggest ethnic backgrounds people claimed were 23% Portuguese , 17% Irish , 9% English , 9% French , 8% Cape Verdean and 4% Puerto Rican . Most of Taunton's immigration occurred near the turn of the 1900s when immigrants came to work in the city's mills. There were 22,045 households , out of which 32.3% had children under the age of 18 living with them, 45.0% were married couples living together, 15.4% had

7068-435: Was 36 years. For every 100 females, there were 92.5 males. For every 100 females age 18 and over, there were 89.2 males. Males had a median income of $ 36,895 versus $ 27,686 for females. The per capita income for the city was $ 19,899. About 10.0% of families and 12.0% of the population were below the poverty line , including 13.9% of those under age 18 and 11.3% of those age 65 or over. Numerous religious groups exist within

7161-486: Was a departure point for over a million U.S. and allied military personnel bound for Europe during World War II. It also functioned as a prisoner of war camp housing German and Italian soldiers. While Camp Myles Standish was later closed in 1946, it was re-purposed as the Paul A Dever School which was a facility that housed mentally disabled persons. The school site of 220 acres (89 ha) was shut down in 1982. This portion

7254-515: Was a major shipping point for grain from the inland rural farm areas of Massachusetts to the rest of the nation via Weir Village and the Taunton River . With the advent of the railroad, Taunton would also become an important transportation hub due to its central location. The city formed the Taunton Municipal Light Plant (TMLP) in 1897, when it decided to purchase the floundering Taunton Electric Lighting Company, making it

7347-479: 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

7440-399: Was among its greatest benefactors and played a significant role in the founding of its church. Described as "the foundress of Taunton" and its matriarch, Poole "was accorded equality of rights, whether in the purchase of lands, [or] in the sharing of iron works holdings," having been a financier of the settlement's first dam and mill built for the manufacture of bar iron . Plymouth Colony

7533-490: 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

7626-625: Was demolished on May 9, 2021. The Taunton Green is the city's central square. Early in its history, "The Green" was used as a training ground for militias in the American Revolution . Some say it was also the site of the historic "Liberty & Union"/"Taunton" flag raising in 1774 by the Sons of Liberty , prior to the American Revolution. Since the early 20th century, Taunton Green has temporarily been transformed during

7719-466: Was formally divided into counties on June 2, 1685, with Taunton becoming the shire town of Bristol County. The counties of Plymouth Colony were transferred to the Province of Massachusetts Bay on the arrival of its charter and governor on May 14, 1692. The Taunton area has been the site of skirmishes and battles during various conflicts, including King Philip's War and the American Revolution . Taunton

7812-454: Was founded by settlers from England and officially incorporated as a town on September 3, 1639. Most of the town's settlers were originally from Taunton in Somerset , England , which led early settlers to name the settlement after that town. At the time of Taunton's incorporation, they explained their choice of name as being "in honor and love to our dear native country." Prior to 1640,

7905-515: 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

7998-426: Was listed on the National Register of Historic Places on July 5, 1984. Taunton, Massachusetts Taunton is a city and county seat of Bristol County, Massachusetts , United States. Taunton is situated on the Taunton River , which winds its way through the city on its way to Mount Hope Bay , 10 miles (16 km) to the south. At the 2020 census , the city had a population of 59,408. Shaunna O'Connell

8091-477: 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

8184-445: 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

8277-541: 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

8370-533: Was re-incorporated as a city on May 11, 1864. In 1656, the first successful iron works in Plymouth Colony was established on the Two Mile River, in what is now part of Raynham . The Taunton Iron Works operated for over 200 years until 1876. It was the first of many iron industries in Taunton. During the 19th century, Taunton became known as the "Silver City", as it was home to many silversmithing operations, including Reed & Barton , F.B. Rogers ,

8463-469: Was the Mason Machine Works , founded by William Mason , which produced machinery for the textile industry, as well as steam locomotives. The Taunton Locomotive Works (begun in 1846) also operated in the city during this time. Taunton was also home to several textile mills (Whittenton Mills) and other industries, such as felt (Bacon Felt) and brick making. During the 19th century, Taunton

8556-473: 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

8649-651: Was turned into an expansion scheme for the existing the Myles Standish Industrial Park, Taunton's north end, which is currently one of the largest in New England, covering an area over 800 acres (320 ha). It services manufacturing, offices, high tech, and distribution centers. The National Weather Service operates a regional weather forecast office that serves much of Massachusetts, all of Rhode Island , and most of northern Connecticut there. The National Weather Service also operates
