54-469: In 1907, the city council decided to build a new city hall at the former site of Eldkvarn . An architectural design competition was held, which first resulted in the selection of drafts by Ragnar Östberg , Carl Westman , Ivar Tengbom jointly with Ernst Torulf , and Carl Bergsten . After a further competition between Westman and Östberg, the latter was assigned the construction of the City Hall, while

108-601: A Vinča culture site in Pločnik ( Serbia ), and believed to have been smelted from a natural tin-copper ore, stannite . Other early examples date to the late 4th millennium BC in Egypt , Susa (Iran) and some ancient sites in China, Luristan (Iran), Tepe Sialk (Iran), Mundigak (Afghanistan), and Mesopotamia (Iraq). Tin bronze was superior to arsenic bronze in that the alloying process could be more easily controlled, and

162-501: A central motif, namely the juxtaposition of city architecture and water that represents a central feature of Stockholm's cityscape as a whole. The hall's style is one of refined eclecticism, blending massive, austere, Northern European brick construction with whimsical elements reminiscent of Venetian Gothic architecture , such as turrets adorned with golden starlets, decorated balconies, wooden masts, and statues. The Blue Hall, with its straight walls and arcades, incorporates elements of

216-524: A copper oxide (eventually becoming copper carbonate) layer is formed, the underlying metal is protected from further corrosion . This can be seen on statues from the Hellenistic period. If copper chlorides are formed, a corrosion-mode called " bronze disease " will eventually completely destroy it. Bronze, or bronze-like alloys and mixtures, were used for coins over a longer period. Bronze was especially suitable for use in boat and ship fittings prior to

270-689: A formal courtyard. Its walls are in fact without blue decorations; the name derives from Östberg's first draft, and is notable as the dining hall where banquets are held after the annual Nobel Prize award ceremony. The organ in the Blue Hall, with its 10,270 pipes, is the largest in Scandinavia. Above the Blue Hall lies the Golden Hall ( Gyllene Salen ), named after the decorative mosaics made of more than 18 million tiles. The mosaics make use of motifs from Swedish history. They were executed by

324-517: A grand gristmill in central Stockholm that burned in 1878 — an event which was known as "the fire of the century". It was located where today the Stockholm City Hall stands. The mill was built in 1805 for Abraham Niclas Edelcrantz with a steam engine built by Samuel Owen . At the time of the blaze, the fire was known as the fire of the century, because of its ferocity and the fact that it could be seen from many points of

378-595: A location in Stockholm County , Sweden is a stub . You can help Misplaced Pages by expanding it . This Swedish history -related article is a stub . You can help Misplaced Pages by expanding it . Bronze Bronze is an alloy consisting primarily of copper , commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium , manganese , nickel , or zinc ) and sometimes non-metals, such as phosphorus , or metalloids , such as arsenic or silicon . These additions produce

432-665: A major influence on the development of cultures. In Europe, a major source of tin was the British deposits of ore in Cornwall , which were traded as far as Phoenicia in the eastern Mediterranean . In many parts of the world, large hoards of bronze artifacts are found, suggesting that bronze also represented a store of value and an indicator of social status. In Europe, large hoards of bronze tools, typically socketed axes (illustrated above), are found, which mostly show no signs of wear. With Chinese ritual bronzes , which are documented in

486-611: A range of alloys that may be harder than copper alone, or have other useful properties, such as strength , ductility , or machinability . The archaeological period in which bronze was the hardest metal in widespread use is known as the Bronze Age . The beginning of the Bronze Age in western Eurasia and India is conventionally dated to the mid-4th millennium BC (~3500 BC), and to the early 2nd millennium BC in China; elsewhere it gradually spread across regions. The Bronze Age

540-551: A sharper edge longer. Bronze was still used during the Iron Age, and has continued in use for many purposes to the modern day. There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin. Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades. Historical "bronzes" are highly variable in composition, as most metalworkers probably used whatever scrap

594-416: Is a better conductor of heat and electricity than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel -base alloys. Bronzes are typically ductile alloys, considerably less brittle than cast iron. Copper and its alloys have a huge variety of uses that reflect their versatile physical, mechanical, and chemical properties . Some common examples are

648-427: Is decorated with the gold-plated cenotaph of 13th century Swedish statesman Birger Jarl . Stockholm City Hall has been the location of a number of cultural productions, including the 1991 music video Fading Like a Flower (Every Time You Leave) by Swedish pop duo Roxette . The small park between the building and Lake Mälaren's shore is adorned with several sculptures, among them Carl Eldh 's ensemble representing

702-527: Is likely that 'nehoshet' refers to copper and its alloys with tin, now called bronze. In the King James Version, there is no use of the word 'bronze' and 'nehoshet' was translated as 'brass'. Modern translations use 'bronze'. Bronze (nehoshet) was used widely in the Tabernacle for items such as the bronze altar (Exodus Ch.27), bronze laver (Exodus Ch.30), utensils, and mirror (Exodus Ch.38). It

756-649: Is that a small gas lamp fell, igniting the many bits of dust and grain on the floor, and it spread from there. As with the Great Fire of London , where a small fire expanded quickly, the fire at the mill in Stockholm started small, but was very poorly dealt with, and managed to spread throughout the factory. Unlike the Great Fire of London, though, it was contained to the area in and around the factory, meaning it did not spread to other parts of Stockholm. However, it

810-453: Is used to make hammers , mallets , wrenches and other durable tools to be used in explosive atmospheres or in the presence of flammable vapors. Bronze is used to make bronze wool for woodworking applications where steel wool would discolor oak . Phosphor bronze is used for ships' propellers, musical instruments, and electrical contacts. Bearings are often made of bronze for its friction properties. It can be impregnated with oil to make

864-541: Is used to make the tone rings of many professional model banjos . The tone ring is a heavy (usually 3 lb; 1.4 kg) folded or arched metal ring attached to a thick wood rim, over which a skin, or most often, a plastic membrane (or head) is stretched – it is the bell bronze that gives the banjo a crisp powerful lower register and clear bell-like treble register. Bronze has also been used in coins; most "copper" coins are actually bronze, with about 4 percent tin and 1 percent zinc. As with coins, bronze has been used in

918-560: The Etruscans were making bronze mirrors in the sixth century BC, and Greek and Roman mirrors followed the same pattern. Although other materials such as speculum metal had come into use, and Western glass mirrors had largely taken over, bronze mirrors were still being made in Japan and elsewhere in the eighteenth century, and are still made on a small scale in Kerala , India. Bronze is

972-513: The Golden Age , when men lived among the gods; the Silver age , where youth lasted a hundred years; and the Bronze Age , the era of heroes. It was first adopted for a sports event at the 1904 Summer Olympics . At the 1896 event, silver was awarded to winners and bronze to runners-up, while at 1900 other prizes were given rather than medals. Bronze is the normal material for the related form of

1026-756: The Kingdom of Benin ; in Europe, Grecian bronzes typically of figures from Greek mythology ; in east Asia , Chinese ritual bronzes of the Shang and Zhou dynasty —more often ceremonial vessels but including some figurine examples. Bronze continues into modern times as one of the materials of choice for monumental statuary. Tiffany Glass Studios, made famous by Louis C. Tiffany commonly referred to his product as favrile glass or " Tiffany glass ," and used bronze in their artisan work for his Tiffany lamps . The largest and most ornate bronze fountain known to be cast in

1080-550: The plaquette , normally a rectangular work of art with a scene in relief , for a collectors' market. Bronze is also associated with eighth wedding anniversaries. There are over 125 references to bronze ('nehoshet'), which appears to be the Hebrew word used for copper and any of its alloys. However, the Old Testament era Hebrews are not thought to have had the capability to manufacture zinc (needed to make brass) and so it

1134-623: The 12th-century Romanesque Baptismal font at St Bartholomew's Church, Liège is sometimes described as bronze and sometimes as brass . In the Bronze Age, two forms of bronze were commonly used: "classic bronze", about 10% tin, was used in casting; and "mild bronze", about 6% tin, was hammered from ingots to make sheets. Bladed weapons were mostly cast from classic bronze, while helmets and armor were hammered from mild bronze. Modern commercial bronze (90% copper and 10% zinc) and architectural bronze (57% copper, 3% lead , 40% zinc) are more properly regarded as brass alloys because they contain zinc as

1188-615: The Berlin, Germany, firm of Puhl & Wagner (Gottfried Heinersdorff), after nine years of negotiations by Gottfried Heinersdorff (1883–1941) for the commission. The southeast corner of the building, immediately adjacent to the shore, is dominated by a monumental tower topped with the Three Crowns , the Swedish national symbol . The tower is 106 metres high and is accessible by lift or a 365 step staircase. The eastern side of its base

1242-401: The artists August Strindberg , Gustaf Fröding and Ernst Josephson , as well as Eldh's bronze sculptures "Sången" and "Dansen" ("The Song" and "The Dance"). To the south-east of the city hall, facing Riddarholmen , is a pillar topped with a statue of Engelbrekt Engelbrektsson .

1296-452: The barrel. It is still widely used today for springs, bearings, bushings, automobile transmission pilot bearings, and similar fittings, and is particularly common in the bearings of small electric motors . Phosphor bronze is particularly suited to precision-grade bearings and springs. It is also used in guitar and piano strings. Unlike steel, bronze struck against a hard surface will not generate sparks, so it (along with beryllium copper )

1350-415: The city became gripped by the fire, noting that ‘the most varied rumours were about the origin of the fire and the most incredible stories were raised’. Despite the fire being so large, they managed to save part of the mill and, perhaps most amazingly, it stayed open until 1906. 59°19′39″N 18°3′17″E  /  59.32750°N 18.05472°E  / 59.32750; 18.05472 This article about

1404-494: The city, dominating the skyline. It was a moment that gripped the city in horror, as citizens watched the fire rage and fill the night sky. The fire occurred in central Stockholm at the Eldkvarn gristmill on 31 October 1878. It was a steam-powered mill built in 1805 that made flour, something that was very important to Stockholm in the 19th century. A variety of different causes have been suggested. The most widely accepted one

1458-438: The former was asked to build Stockholm Court House . Östberg modified his original draft using elements of Westman's design, including the tower. During construction, Östberg constantly reworked his plans, resulting in the addition of the lantern on top of the tower, and the abandonment of the blue glazed tiles in the Blue Hall. Oskar Asker was employed as construction leader and Paul Toll, of builders Kreuger & Toll, designed

1512-415: The foundations. Georg Greve also assisted in preparing the plans. Construction took twelve years, from 1911 to 1923. Nearly eight million red bricks were used. The dark red bricks, called "munktegel" (monks's brick) because of their traditional use in the construction of monasteries and churches, were provided by Lina brickworks of Södertälje . The building was inaugurated on Saturday 23 June 1923, which

1566-545: The high electrical conductivity of pure copper, low-friction properties of bearing bronze (bronze that has a high lead content— 6–8%), resonant qualities of bell bronze (20% tin, 80% copper), and resistance to corrosion by seawater of several bronze alloys. The melting point of bronze varies depending on the ratio of the alloy components and is about 950 °C (1,742 °F). Bronze is usually nonmagnetic, but certain alloys containing iron or nickel may have magnetic properties. Typically bronze oxidizes only superficially; once

1620-699: The highest form of sculpture in Ancient Greek art , though survivals are few, as bronze was a valuable material in short supply in the Late Antique and medieval periods. Many of the most famous Greek bronze sculptures are known through Roman copies in marble, which were more likely to survive. In India, bronze sculptures from the Kushana ( Chausa hoard ) and Gupta periods ( Brahma from Mirpur-Khas , Akota Hoard, Sultanganj Buddha ) and later periods ( Hansi Hoard) have been found. Indian Hindu artisans from

1674-484: The inscriptions they carry and from other sources, the case is clear. These were made in enormous quantities for elite burials, and also used by the living for ritual offerings. Though bronze is generally harder than wrought iron , with Vickers hardness of 60–258 vs. 30–80, the Bronze Age gave way to the Iron Age after a serious disruption of the tin trade: the population migrations of around 1200–1100 BC reduced

1728-824: The main alloying ingredient. They are commonly used in architectural applications. Plastic bronze contains a significant quantity of lead, which makes for improved plasticity, and was possibly used by the ancient Greeks in ship construction. Silicon bronze has a composition of Si: 2.80–3.80%, Mn: 0.50–1.30%, Fe: 0.80% max., Zn: 1.50% max., Pb: 0.05% max., Cu: balance. Other bronze alloys include aluminium bronze , phosphor bronze , manganese bronze, bell metal , arsenical bronze , speculum metal , bismuth bronze , and cymbal alloys . Copper-based alloys have lower melting points than steel or iron and are more readily produced from their constituent metals. They are generally about 10 percent denser than steel, although alloys using aluminum or silicon may be slightly less dense. Bronze

1782-462: The manufacture of various types of medals for centuries, and " bronze medals " are known in contemporary times for being awarded for third place in sporting competitions and other events. The term is now often used for third place even when no actual bronze medal is awarded. The usage in part arose from the trio of gold , silver and bronze to represent the first three Ages of Man in Greek mythology:

1836-673: The massive bronze doors to the United States Supreme Court Building in Washington, DC. Before it became possible to produce glass with acceptably flat surfaces, bronze was a standard material for mirrors. Bronze was used for this purpose in many parts of the world, probably based on independent discoveries. Bronze mirrors survive from the Egyptian Middle Kingdom (2040–1750 BC), and China from at least c.  550 BC . In Europe,

1890-801: The names of individual alloys. This is done (at least in part) to prevent database searches from failing merely because of errors or disagreements in the naming of historic copper alloys. The word bronze (1730–1740) is borrowed from Middle French bronze (1511), itself borrowed from Italian bronzo ' bell metal, brass ' (13th century, transcribed in Medieval Latin as bronzium ) from either: The discovery of bronze enabled people to create metal objects that were harder and more durable than previously possible. Bronze tools , weapons , armor , and building materials such as decorative tiles were harder and more durable than their stone and copper (" Chalcolithic ") predecessors. Initially, bronze

1944-581: The period of the Chola empire in Tamil Nadu used bronze to create intricate statues via the lost-wax casting method with ornate detailing depicting the deities of Hinduism . The art form survives to this day, with many silpis, craftsmen, working in the areas of Swamimalai and Chennai . In antiquity other cultures also produced works of high art using bronze. For example: in Africa, the bronze heads of

1998-424: The preferred metal for bells in the form of a high tin bronze alloy known as bell metal , which is typically about 23% tin. Nearly all professional cymbals are made from bronze, which gives a desirable balance of durability and timbre . Several types of bronze are used, commonly B20 bronze , which is roughly 20% tin, 80% copper, with traces of silver, or the tougher B8 bronze made from 8% tin and 92% copper. As

2052-452: The proprietary Oilite and similar material for bearings. Aluminum bronze is hard and wear-resistant, and is used for bearings and machine tool ways. The Doehler Die Casting Co. of Toledo, Ohio were known for the production of Brastil , a high tensile corrosion resistant bronze alloy. The Seagram Building on New York City 's Park Avenue is the "iconic glass box sheathed in bronze, designed by Mies van der Rohe ." The Seagram Building

2106-454: The ready availability of silicon bronze brazing rod, which allows color-matched repair of defects in castings. Aluminum is also used for the structural metal aluminum bronze. Bronze parts are tough and typically used for bearings , clips, electrical connectors and springs . Bronze also has low friction against dissimilar metals, making it important for cannons prior to modern tolerancing , where iron cannonballs would otherwise stick in

2160-690: The resulting alloy was stronger and easier to cast. Also, unlike those of arsenic , metallic tin and the fumes from tin refining are not toxic . Tin became the major non-copper ingredient of bronze in the late 3rd millennium BC. Ores of copper and the far rarer tin are not often found together (exceptions include Cornwall in the United Kingdom, one ancient site in Thailand and one in Iran), so serious bronze work has always involved trade with other regions. Tin sources and trade in ancient times had

2214-478: The shipping of tin around the Mediterranean and from Britain, limiting supplies and raising prices. As the art of working in iron improved, iron became cheaper and improved in quality. As later cultures advanced from hand- wrought iron to machine- forged iron (typically made with trip hammers powered by water), blacksmiths also learned how to make steel . Steel is stronger and harder than bronze and holds

2268-469: The tin content in a bell or cymbal rises, the timbre drops. Bronze is also used for the windings of steel and nylon strings of various stringed instruments such as the double bass , piano, harpsichord , and guitar. Bronze strings are commonly reserved on pianoforte for the lower pitch tones, as they possess a superior sustain quality to that of high-tensile steel. Bronzes of various metallurgical properties are widely used in struck idiophones around

2322-439: The unusual and desirable property of expanding slightly just before they set, thus filling the finest details of a mould. Then, as the bronze cools, it shrinks a little, making it easier to separate from the mould. The Assyrian king Sennacherib (704–681 BC) claims to have been the first to cast monumental bronze statues (of up to 30 tonnes) using two-part moulds instead of the lost-wax method . Bronze statues were regarded as

2376-419: The wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion. Bronze is still commonly used in ship propellers and submerged bearings. In the 20th century, silicon was introduced as the primary alloying element, creating an alloy with wide application in industry and the major form used in contemporary statuary . Sculptors may prefer silicon bronze because of

2430-657: The world was by the Roman Bronze Works and General Bronze Corporation in 1952. The material used for the fountain, known as statuary bronze, is a quaternary alloy made of copper, zinc, tin, and lead, and traditionally golden brown in color. This was made for the Andrew W. Mellon Memorial Fountain in Federal Triangle in Washington, DC. Another example of the massive, ornate design projects of bronze, and attributed to General Bronze/Roman Bronze Works were

2484-710: The world, notably bells, singing bowls, gongs , cymbals, and other idiophones from Asia. Examples include Tibetan singing bowls , temple bells of many sizes and shapes, Javanese gamelan , and other bronze musical instruments . The earliest bronze archeological finds in Indonesia date from 1–2 BC, including flat plates probably suspended and struck by a wooden or bone mallet. Ancient bronze drums from Thailand and Vietnam date back 2,000 years. Bronze bells from Thailand and Cambodia date back to 3600 BC. Some companies are now making saxophones from phosphor bronze (3.5 to 10% tin and up to 1% phosphorus content). Bell bronze/B20

2538-556: Was believed to be the 400th anniversary of Gustav Vasa's entrance into Stockholm in 1523 . However, the anniversary was actually on 4 July, because it occurred on 24 June 1523 in the Julian calendar , which would be 4 July 1523 in the Gregorian . Verner von Heidenstam and Hjalmar Branting delivered the inaugurational speeches. Stockholm City Hall is an example of National Romantic style . The site, overlooking Riddarfjärden, inspired

2592-429: Was followed by the Iron Age starting about 1300 BC and reaching most of Eurasia by about 500 BC, although bronze continued to be much more widely used than it is in modern times. Because historical artworks were often made of brasses (copper and zinc) and bronzes of different metallic compositions, modern museum and scholarly descriptions of older artworks increasingly use the generalized term "copper alloy" instead of

2646-470: Was large enough and powerful enough that it made a real impression on the people of the city. Dagens Nyheter, one of the most popular newspapers in Sweden, wrote extensively about the fire and noted that ‘in view of the fierce outbreaks of the fire and the fierce widening of the fire, the entire capital and its immediate surroundings were illuminated as through a magic wand’. The newspaper also commented on how

2700-525: Was made out of copper and arsenic or from naturally or artificially mixed ores of those metals, forming arsenic bronze . The earliest known arsenic-copper-alloy artifacts come from a Yahya Culture (Period V 3800-3400 BCE) site, at Tal-i-Iblis on the Iranian plateau , and were smelted from native arsenical copper and copper-arsenides, such as algodonite and domeykite . The earliest tin-copper-alloy artifact has been dated to c.  4650 BC , in

2754-474: Was mentioned in the account of Moses holding up a bronze snake on a pole in Numbers Ch.21. In First Kings, it is mentioned that Hiram was very skilled in working with bronze, and he made many furnishings for Solomon's Temple including pillars, capitals, stands, wheels, bowls, and plates, some of which were highly decorative (see I Kings 7:13-47). Bronze was also widely used as battle armor and helmet, as in

2808-424: Was not only the most expensive building of its time — $ 36 million — but it was the first building in the world with floor-to-ceiling glass walls. Mies van der Rohe achieved the crisp edges that were custom-made with specific detailing by General Bronze and "even the screws that hold in the fixed glass-plate windows were made of brass." Bronze is widely used for casting bronze sculptures . Common bronze alloys have

2862-481: Was on hand; the metal of the 12th-century English Gloucester Candlestick is bronze containing a mixture of copper, zinc, tin, lead, nickel, iron, antimony, arsenic and an unusually large amount of silver – between 22.5% in the base and 5.76% in the pan below the candle. The proportions of this mixture suggest that the candlestick was made from a hoard of old coins. The 13th-century Benin Bronzes are in fact brass, and

2916-593: Was the first time that an entire building was sheathed in bronze. The General Bronze Corporation fabricated 3,200,000 pounds (1,600 tons) of bronze at its plant in Garden City, New York . The Seagram Building is a 38-story, 516-foot bronze-and- topaz -tinted glass building. The building looks like a "squarish 38-story tower clad in a restrained curtain wall of metal and glass." "Bronze was selected because of its color, both before and after aging, its corrosion resistance, and its extrusion properties. In 1958, it
