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 applications and are ...

Cut Steel Jewellery
Cut steel jewellery is a form of jewellery composed of steel that was popular between the 18th century and the end of the 1930s. Design The basic design of cut steel jewellery is a thin metal baseplate onto which closely placed steel studs were riveted or scewed. The baseplate could be made from various metals such as brass, tin or silver alloys. Early cut steel consisted of individual steel studs that had been polished and inserted into metal frames. More complicated designs used multiple baseplates held together by small bits of metal. In the early 19th century the manufacturing process shifted towards using stamped strips in place of individual steel studs. The idea behind the design was that the polished steel faces would catch the light and sparkle in a similar way to the then highly fashionable diamonds. The studs were made by forming them from steel and giving them a partial polish before case-hardening and giving them a final polish. Aside from the studs some items of cut ...

James Tassie
James Tassie (1735–1799) was a Scottish gem engraver and modeller. He is remembered for a particular style of miniature medallion heads, portraying the profiles of the rich and famous of Britain, and for making and selling large numbers of "Tassie casts" of engraved gems for collectors. Life He was born of humble parentage at Pollokshaws, in Glasgow. During his earlier years he worked as a stonemason, but, having seen the collection of paintings brought together in Glasgow by Robert Foulis and Andrew Foulis, the printers, he removed to Glasgow, attended the academy which had been established there by the brothers Foulis, and became one of the most distinguished pupils of the school. Subsequently, he visited Dublin in search of commissions, and there became acquainted with Henry Quin, who had been experimenting, as an amateur, in imitating antique engraved gems in coloured pastes. He engaged Tassie as an assistant, and together they perfected the discovery of an enamel, ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josiah Wedgwood
Josiah Wedgwood (12 July 1730 – 3 January 1795) was an English potter, entrepreneur and abolitionist. Founding the Wedgwood company in 1759, he developed improved pottery bodies by systematic experimentation, and was the leader in the industrialisation of the manufacture of European pottery. The renewed classical enthusiasms of the late 1760s and early 1770s were of major importance to his sales promotion. His expensive goods were in much demand from the upper classes, while he used emulation effects to market cheaper sets to the rest of society. Every new invention that Wedgwood produced – green glaze, creamware, black basalt, and jasperware – was quickly copied. Having once achieved efficiency in production, he obtained efficiencies in sales and distribution. His showrooms in London gave the public the chance to see his complete range of tableware. Wedgwood's company never made porcelain during his lifetime, but specialised in fine earthenwares and stonewares that had ...

Jasperware
Jasperware, or jasper ware, is a type of pottery first developed by Josiah Wedgwood in the 1770s. Usually described as stoneware, it has an unglazed matte "biscuit" finish and is produced in a number of different colours, of which the most common and best known is a pale blue that has become known as Wedgwood Blue. Relief decorations in contrasting colours (typically in white but also in other colours) are characteristic of jasperware, giving a cameo effect. The reliefs are produced in moulds and applied to the ware as sprigs. After several years of experiments, Wedgwood began to sell jasperware in the late 1770s, at first as small objects, but from the 1780s adding large vases. It was extremely popular, and after a few years many other potters devised their own versions. Wedgwood continued to make it into the 21st century. The decoration was initially in the fashionable Neoclassical style, which was often used in the following centuries, but it could be made to suit oth ...

Millesimal Fineness
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of ''fine metal'' therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% and 24 karat gold is considered 100% g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gothic Architecture
Gothic architecture (or pointed architecture) is an architectural style that was prevalent in Europe from the late 12th to the 16th century, during the High and Late Middle Ages, surviving into the 17th and 18th centuries in some areas. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. It originated in the Île-de-France and Picardy regions of northern France. The style at the time was sometimes known as ''opus Francigenum'' (lit. French work); the term ''Gothic'' was first applied contemptuously during the later Renaissance, by those ambitious to revive the architecture of classical antiquity. The defining design element of Gothic architecture is the pointed or ogival arch. The use of the pointed arch in turn led to the development of the pointed rib vault and flying buttresses, combined with elaborate tracery and stained glass windows. At the Abbey of Saint-Denis, near Paris, the choir was reconstructed between 1140 and 1144, draw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neoclassicism
Neoclassicism (also spelled Neo-classicism) was a Western cultural movement in the decorative and visual arts, literature, theatre, music, and architecture that drew inspiration from the art and culture of classical antiquity. Neoclassicism was born in Rome largely thanks to the writings of Johann Joachim Winckelmann, at the time of the rediscovery of Pompeii and Herculaneum, but its popularity spread all over Europe as a generation of European art students finished their Grand Tour and returned from Italy to their home countries with newly rediscovered Greco-Roman ideals. The main Neoclassical movement coincided with the 18th-century Age of Enlightenment, and continued into the early 19th century, laterally competing with Romanticism. In architecture, the style continued throughout the 19th, 20th and up to the 21st century. European Neoclassicism in the visual arts began c. 1760 in opposition to the then-dominant Rococo style. Rococo architecture emphasizes grace, ornamentati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria And Albert Museum
The Victoria and Albert Museum (often abbreviated as the V&A) in London is the world's largest museum of applied arts, decorative arts and design, housing a permanent collection of over 2.27 million objects. It was founded in 1852 and named after Queen Victoria and Prince Albert.

Iron Work Necklace
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 I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
