Ironwork
Ironwork is any weapon, artwork, utensil, or architectural feature made of iron, especially one used for decoration. There are two main types of ironwork: wrought iron and cast iron. While the use of iron dates as far back as 4000BC, it was the Hittites who first knew how to extract it (see iron ore) and develop weapons. Use of iron was mainly utilitarian until the Middle Ages; it became widely used for decoration in the period between the 16th and 19th century. Wrought iron Wrought ironwork is forged by a blacksmith using an anvil. The earliest known ironwork are beads from Jirzah in Egypt dating from 3500 BC and made from meteoric iron with the earliest use of smelted iron dates back to Mesopotamia. However, the first use of conventional smelting and purification techniques that modern society labels as true iron-working dates back to the Hittites in around 2000 BC. Knowledge about the use of iron spread from the Middle East to Greece and the Aegean region by 1000BC and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jean Tijou
Jean Tijou () was a French Huguenot ironworker. He is known solely through his work in England, where he worked on several of the key English Baroque buildings. Very little is known of his biography. He arrived in England in c. 1689 and enjoyed the patronage of William III and Mary II where he was titled as England's Best Wrought-iron Designer. He was employed at St Paul's for twenty years. Not only did he work for royal destinations, but he also worked for estates and other private homes located on the countryside. He left England for the continent c. 1712. He was father-in-law to the painter of decorative schemes Louis Laguerre who married in St Martin-in-the-Fields in London. Tijou had a wife named Ann Tijou as well as a daughter. She was married in the church of St. Martin's. Both wife and daughter were buried there as well. Little else is known of Jean Tijou or his training other than that he was a master metalworker. Works His major commissions include gates and railing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron– carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applicatio ...

Iron
Iron () is a chemical element with symbol Fe (from la, ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. In its metallic state, iron is rare in the Earth's crust, limited mainly to deposition by meteorites. Iron ores, by contrast, are among the most abundant in the Earth's crust, although extracting usable metal from them requires kilns or furnaces capable of reaching or higher, about higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BCE and the use of iron tools and weapons began to displace copper alloys, in some regions, only around 1200 BCE. That event is considered the transition from the Bronze Age to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). 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 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 hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julio González (sculptor)
Julio González i Pellicer (21 September 1876 – 27 March 1942), born in Barcelona, was a Spanish sculptor and painter who developed the expressive use of iron as a medium for modern sculpture. He was from a lineage of metalsmith workers and artists. His grandfather was a goldsmith worker and his father, Concordio González, a metalsmith worker who taught him the techniques of metalsmith in his childhood years. His mother, Pilar Pellicer Fenés, came from a long line of artists. Julio attended Circol Artist Sant Luc, a Catholic school whose model of education was based on the medieval art guilds and influenced by the Arts and Crafts movement in England. Biography Youth Julio González Pellicer was born in Barcelona, on September 21, 1876. He came from a line of metalsmith workers; his grandfather was a goldsmith in Galicia. González's father, Concordio González, owned a workshop and as a young boy, González learned from him the techniques of gold, silver, and iron meta ...

Hampton Court
Hampton Court Palace is a Grade I listed royal palace in the London Borough of Richmond upon Thames, southwest and upstream of central London on the River Thames. The building of the palace began in 1514 for Cardinal Thomas Wolsey, the chief minister of Henry VIII. In 1529, as Wolsey fell from favour, the cardinal gave the palace to the king to check his disgrace. The palace went on to become one of Henry's most favoured residences; soon after acquiring the property, he arranged for it to be enlarged so that it might more easily accommodate his sizeable retinue of courtiers. Along with St James' Palace, it is one of only two surviving palaces out of the many the king owned. The palace is currently in the possession of King Charles III and the Crown. In the following century, King William III's massive rebuilding and expansion work, which was intended to rival the Palace of Versailles, destroyed much of the Tudor palace.Dynes, p. 90. His work ceased in 1694, leaving the pala ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Paul's Cathedral
St Paul's Cathedral is an Anglicanism, Anglican cathedral in London and is the seat of the Bishop of London. The cathedral serves as the mother church of the Diocese of London. It is on Ludgate Hill at the highest point of the City of London and is a Listed Building, Grade I listed building. Its dedication to Paul the Apostle dates back to the original church on this site, founded in AD 604. The present structure, dating from the late 17th century, was designed in the English Baroque style by Sir Christopher Wren. Its construction, completed in Wren's lifetime, was part of a major rebuilding programme in the city after the Great Fire of London. The earlier Gothic cathedral (Old St Paul's Cathedral), largely destroyed in the Great Fire, was a central focus for medieval and early modern London, including Paul's walk and St Paul's Churchyard, being the site of St Paul's Cross. The cathedral is one of the most famous and recognisable sights of London. Its dome, surrounded by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetylene Torch
Principle of burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, bio diesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen- acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. A common propane/air flame burns at about , a propane/oxygen flame burns at about , an oxyhydrogen flame burns at and an acetylene/oxygen flame burns at about . During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of exce ...
