Osmond Iron
Osmond iron (also spelt osmund and also called osborn) was wrought iron made by a particular process. This is associated with the first European production of cast iron in furnaces such as Lapphyttan in Sweden. Osmonds appear in some of the earliest English Customs accounts, for example in 1325. The ''kappe'' a Swedish iron weight used for osmond occurs in a commercial treaty in Novgorod in 1203, and this implies the production of osmond iron. Osmond iron was made by melting pig iron in a hearth that is narrower and deeper than a typical finery in an English finery forge. The hearth had a charcoal fire blown with bellows through a tuyere. As the iron melted, the drops fell through the blast and congealed. They were then lifted with an iron bar into the blast. As they melted they were caught on the end of a large staff, held in the fire and turned rapidly so that the drops spread out, forming a ball. Osmonds reached England during the later Middle Ages through the port of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altena - Burg In - Osemund 02 Ies
Altena (; Westphalian: ''Altenoa'') is a town in the district of Märkischer Kreis, North Rhine-Westphalia, Germany. The town's castle is the origin for the later Dukes of Berg. Altena is situated on the Lenne river valley, in the northern stretches of the Sauerland. History Altena Castle was built in the early 12th century, as a stronghold of the older Counts of Berg. A short time later a village was founded beneath the hill, with the castle alongside the river Lenne, which feeds into the river Ruhr. After the distribution of the Berg family estates in 1161, Altena became the centre of the County of Altena. The first Count of Altena became Eberhard I, Count of Berg-Altena. In 1180, after the death of the first count, the county was divided between the two oldest sons: Arnold of Altena and Friedrich of Altena. The third son, Adolf of Altena, became Archbishop of Cologne. Arnold was provided with on half of the Castle and County of Altena, the Castle Hövel and some estates as fie ...

Westfalen
Westphalia (; german: Westfalen ; nds, Westfalen ) is a region of northwestern Germany and one of the three historic parts of the state of North Rhine-Westphalia. It has an area of and 7.9 million inhabitants. The territory of the region is almost identical with the historic Province of Westphalia, which was a part of the Kingdom of Prussia from 1815 to 1918 and the Free State of Prussia from 1918 to 1946. In 1946, Westphalia merged with North Rhine, another former part of Prussia, to form the newly created state of North Rhine-Westphalia. In 1947, the state with its two historic parts was joined by a third one: Lippe, a former principality and free state. The seventeen districts and nine independent cities of Westphalia and the single district of Lippe are members of the Westphalia-Lippe Regional Association (''Landschaftsverband Westfalen-Lippe''). Previous to the formation of Westphalia as a province of Prussia and later state part of North Rhine-Westphalia, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgical Processes
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mi ...

Ferrous Alloys
In chemistry, the adjective Ferrous indicates a compound that contains iron(II), meaning iron in its +2 oxidation state, possibly as the divalent cation Fe2+. It is opposed to " ferric" or iron(III), meaning iron in its +3 oxidation state, such as the trivalent cation Fe3+.ferrous entry in the online dictionary. Accessed on 2008-04-19. This usage has been largely replaced by the nomenclature, which calls for the oxidation state being indicated by Roman numerals in parentheses, such as |

Tilt Hammer
A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, decorticating and polishing of grain in agriculture. In mining, trip hammers were used for crushing metal ores into small pieces, although a stamp mill was more usual for this. In finery forges they were used for drawing out blooms made from wrought iron into more workable bar iron. They were also used for fabricating various articles of wrought iron, latten (an early form of brass), steel and other metals. One or more trip hammers were set up in a forge, also known variously as a hammer mill, hammer forge or hammer works. The hammers were usually raised by a cam and then released to fall under the force of gravity. Historically, trip hammers were often powered hydraulically by a water wheel. Trip hammers are known to have been used in Imperial China since the Western Han dynasty. They also existed in the contemporary Greco-Roman world, ...

Company Of Mineral And Battery Works
The Company of Mineral and Battery Works was, (with the Society of the Mines Royal), one of two mining monopolies created by Elizabeth I. The Company's rights were based on a patent granted to William Humfrey on 17 September 1565. This was replaced on 28 May 1568 by a patent of incorporation, making it an early joint stock company. The Society of the Mines Royal was incorporated on the same day. Shareholders The original shareholders were: * William Humfrey * Christopher Schutz * Sir Nicholas Bacon *Thomas Howard, 4th Duke of Norfolk * William Herbert, 1st Earl of Pembroke *Robert Dudley, 1st Earl of Leicester *William Brooke, 10th Baron Cobham *Sir William Cecil * Sir Walter Mildmay *Sir Henry Sidney *Sir Francis Jobson * Sir William Garrard, alderman * Sir Rowland Hayward *John Tamworth * Peter Osborne * Thomas Cecil *Francis Agarde * Thomas Fleetwood *William Roberts *Henry Coddenham *Robert Christmas *Roger Wetherall * William Patten *Christopher Chewte *Thomas Smythe *Will ...

Tintern
Tintern ( cy, Tyndyrn) is a village in the community of Wye Valley, on the west bank of the River Wye in Monmouthshire, Wales, close to the border with England, about north of Chepstow. It is popular with tourists, in particular for the scenery and the ruined Tintern Abbey. Modern Tintern has been formed through the coalescence of two historic villages; Tintern Parva, forming the northern end of the village, and Chapel Hill, which forms the southern end. The village is designated as a Conservation Area. In 2022 the community was renamed from "Tintern" to "Wye Valley" and had boundary changes. History Early history A ford across the navigable and tidal River Wye was in use in Roman times, close to the site of the abbey. After the Romans withdrew from Wales, the kingdom of Gwent emerged, and, according to tradition, in the 6th century one of their kings, Tewdrig, came out of retirement as a Tintern hermit to defeat the invading Saxons in battle, perhaps at a site known today as ...

Wire Drawing
Wire drawing is a metalworking process used to reduce the cross-section of a wire by pulling the wire through a single, or series of, drawing die(s). There are many applications for wire drawing, including electrical wiring, cables, tension-loaded structural components, springs, paper clips, spokes for wheels, and stringed musical instruments. Although similar in process, drawing is different from extrusion, because in drawing the wire is pulled, rather than pushed, through the die. Drawing is usually performed at room temperature, thus classified as a cold working process, but it may be performed at elevated temperatures for large wires to reduce forces. Process The wire drawing process is quite simple in concept. The wire is prepared by shrinking the beginning of it, by hammering, filing, rolling or swaging, so that it will fit through the die; the wire is then pulled through the die. As the wire is pulled through the die, its volume remains the same, so as the diameter dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Humfrey
William Humfrey (also Humphrey or Humphreys) (c.1515–1579) was an English goldsmith, mining promoter, and Assay Master at the Royal Mint during the reign of Elizabeth I. Life Little is known of Humfrey's life before 1560, when he is recorded as a member of the Worshipful Company of Goldsmiths in London, and as a resident of the parish of St Vedast. He obtained the patronage of Sir William Cecil, later Lord Burghley, who 'considered him an expert on metallurgical matters', and provided him with both financial and political backing. Humfrey was appointed Assay Master at the Royal Mint in 1561. German technologists had recently been brought to England to assist with the recoinage of the debased English currency, and through these contacts both Humfrey and Cecil became convinced that German metallurgical techniques could be used in the development of the English mining industry. In particular, Humfrey needed someone knowledgeable about calamine ore, essential to the productio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
