England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England and made popular by its use in Arthurian legend; the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximate
Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state, the Zn2+ and Mg2+ ions are of similar size. Zinc has five stable isotopes; the most common zinc ore is sphalerite, a zinc sulfide mineral. The largest workable lodes are in Australia and the United States. Zinc is refined by froth flotation of the ore and final extraction using electricity. Brass, an alloy of copper and zinc in various proportions, was used as early as the third millennium BC in the Aegean, the United Arab Emirates, Kalmykia and Georgia, the second millennium BC in West India, Iran, Syria and Israel/Palestine. Zinc metal was not produced on a large scale until the 12th century in India, though it was known to the ancient Romans and Greeks; the mines of Rajasthan have given definite evidence of zinc production going back to the 6th century BC. To date, the oldest evidence of pure zinc comes from Zawar, in Rajasthan, as early as the 9th century AD when a distillation process was employed to make pure zinc.
Alchemists burned zinc in air to form what they called "philosopher's wool" or "white snow". The element was named by the alchemist Paracelsus after the German word Zinke. German chemist Andreas Sigismund Marggraf is credited with discovering pure metallic zinc in 1746. Work by Luigi Galvani and Alessandro Volta uncovered the electrochemical properties of zinc by 1800. Corrosion-resistant zinc plating of iron is the major application for zinc. Other applications are in electrical batteries, small non-structural castings, alloys such as brass. A variety of zinc compounds are used, such as zinc carbonate and zinc gluconate, zinc chloride, zinc pyrithione, zinc sulfide, dimethylzinc or diethylzinc in the organic laboratory. Zinc is an essential mineral, including to postnatal development. Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children, deficiency causes growth retardation, delayed sexual maturation, infection susceptibility, diarrhea.
Enzymes with a zinc atom in the reactive center are widespread in biochemistry, such as alcohol dehydrogenase in humans. Consumption of excess zinc may cause ataxia and copper deficiency. Zinc is a bluish-white, diamagnetic metal, though most common commercial grades of the metal have a dull finish, it is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures but becomes malleable between 100 and 150 °C. Above 210 °C, the metal can be pulverized by beating. Zinc is a fair conductor of electricity. For a metal, zinc has low melting and boiling points; the melting point is the lowest of all the d-block metals aside from cadmium. Many alloys contain zinc, including brass. Other metals long known to form binary alloys with zinc are aluminium, bismuth, iron, mercury, tin, cobalt, nickel and sodium.
Although neither zinc nor zirconium are ferromagnetic, their alloy ZrZn2 exhibits ferromagnetism below 35 K. A bar of zinc generates a characteristic sound when bent, similar to tin cry. Zinc makes up about 75 ppm of Earth's crust. Soil contains zinc in 5–770 ppm with an average 64 ppm. Seawater has only 30 ppb and the atmosphere, 0.1–4 µg/m3. The element is found in association with other base metals such as copper and lead in ores. Zinc is a chalcophile, meaning the element is more to be found in minerals together with sulfur and other heavy chalcogens, rather than with the light chalcogen oxygen or with non-chalcogen electronegative elements such as the halogens. Sulfides formed as the crust solidified under the reducing conditions of the early Earth's atmosphere. Sphalerite, a form of zinc sulfide, is the most mined zinc-containing ore because its concentrate contains 60–62% zinc. Other source minerals for zinc include smithsonite, hemimorphite and sometimes hydrozincite. With the exception of wurtzite, all these other minerals were formed by weathering of the primordial zinc sulfides.
Identified world zinc resources total about 1.9–2.8 billion tonnes. Large deposits are in Australia and the United States, with the largest reserves in Iran; the most recent estimate of reserve base for zinc was made in 2009 and calculated to be 480 Mt. Zinc reserves, on the other hand, are geologically identified ore bodies whose suitability for recovery is economically based at the time of determination. Since exploration and mine development is an ongoing process, the amount of zinc reserves is not a fixed number and sustainability of zinc ore supplies cannot be judged by extrapolating the combined mine life of today's zinc mines; this concept is well supported by data from the United States Geol
West Midlands (region)
The West Midlands is one of nine official regions of England at the first level of NUTS for statistical purposes. It covers the western half of the area traditionally known as the Midlands, it contains Birmingham and the larger West Midlands conurbation, the third most populous in the United Kingdom. The City of Coventry is located within the West Midlands county, but is separated from the conurbation to the west by several miles of green belt; the region contains 6 shire counties which stretch from the Welsh Border to the East Midlands. The region is geographically diverse, from the urban central areas of the conurbation to the rural western counties of Shropshire and Herefordshire which border Wales; the longest river in the UK, the River Severn, traverses the region southeastwards, flowing through the county towns of Shrewsbury and Worcester, the Ironbridge Gorge, a UNESCO World Heritage Site. Staffordshire is home to the industrialised Potteries conurbation, including the city of Stoke-on-Trent, the Staffordshire Moorlands area, which borders the southeastern Peak District National Park near Leek.
The region encompasses five Areas of Outstanding Natural Beauty, the Wye Valley, Shropshire Hills, Cannock Chase, Malvern Hills, parts of the Cotswolds. Warwickshire is home to the towns of Stratford upon Avon, birthplace of writer William Shakespeare, the birthplace of Rugby football and Nuneaton, birthplace to author George Eliot; the official region contains the ceremonial counties of Herefordshire, Staffordshire, West Midlands and Worcestershire. There is some confusion in the use of the term "West Midlands", as the name is used for the much smaller West Midlands county and conurbation, in the central belt of the Midlands and on the eastern side of the West Midlands Region, it is still used by various organisations within that area, such as West Midlands Police and West Midlands Fire Service. The highest point in the region is Black Mountain, at 703 metres in west Herefordshire on the border with Powys, Wales; the region contains five Areas of Outstanding Natural Beauty, including the Shropshire Hills, Malvern Hills and Cannock Chase, parts of the Wye Valley and Cotswolds.
The Peak District national park stretches into the northern corner of Staffordshire. Served by many lines in the urban areas such as the West Coast Main Line and branches; the Welsh Marches Line and the Cotswold Line transect the region as well as the Cross Country Route and Chiltern Line. There are plans to reopen the Honeybourne Line. Numerous notable roads pass with most converging around the central conurbation; the M5, which connects South West England to the region, passes through Worcestershire, near to Worcester, through the West Midlands county, past West Bromwich, with its northern terminus at its junction with the M6 just south of Walsall. The M6, which has its southern terminus just outside the southeast of the region at its junction with the M1, which connects the region to North West England, passes Rugby and Nuneaton in Warwickshire and Birmingham, Stafford and Stoke-on-Trent in Staffordshire; the M6 toll provides an alternative route to the M6 between Coleshill and Cannock, passing north of Sutton Coldfield and just south of Lichfield.
The M40 connects the region through South East England to London, with its northern terminus at its junction with the M42. The M42 connects the M5 at Bromsgrove, passing around the south and east of Birmingham, joining the M40 and M6, passing Solihull and Castle Bromwich, to Tamworth, northeast of Birmingham; the M50 connects the M5 from near Tewkesbury to Ross-on-Wye in the southwest. The M54 connects Wellington in the west, to the M6 near Cannock; the A5 road traverses the region northwest-southeast, passing through Shrewsbury, Cannock and Nuneaton. The longest elevated road viaduct in the UK is the 3 miles section from Gravelly Hill to Castle Bromwich on the M6, opened on 24 May 1972; the section of the A45 in Coventry from Willenhall to Allesley in 1939 was one of the UK's first large planned road schemes. Princes Square in Wolverhampton had Britain's first automatic traffic lights on 5 November 1927. On 13 January 2012, 34-year-old Ben Westwood of Wednesfield, was caught by the police, when speeding at 180 mph, in an Audi RS5 with a Lamborghini engine, from Wolverhampton up to Stafford on the M6, back again.
He was travelling so fast that he was outpacing the Central Counties Air Operations Unit Eurocopter helicopter. He and the vehicle had been in fifteen smash and grab raids and he was jailed for nine years at Wolverhampton Crown Court in August 2012; as part of the transport planning system, the Regional Assembly is under statutory requirement to produce a regional transport strategy to provide long term planning for transport in the region. This involves region wide transport schemes such as those carried out by Highways England and Network Rail. Within the region, the local transport authorities carry out transport planning through the use of a local transport plan which outlines their strategies and implementation programme; the most recent LTP is that for the period 2006–11. In the West Midlands region, the following transport authorities have published their LTP online: Herefordshire, Shropshire U. A. Staffordshire and Wrekin U. A. Warwickshire, West Midlands and Worcestershire; the transport authority of Stoke-on-Trent U.
A. publishes a joint local transport plan in partnership with
An ingot is a piece of pure material metal, cast into a shape suitable for further processing. In steelmaking, it is the first step among semi-finished casting products. Ingots require a second procedure of shaping, such as cold/hot working, cutting, or milling to produce a useful final product. Non-metallic and semiconductor materials prepared in bulk form may be referred to as ingots when cast by mold based methods. Precious metal ingots can be used as a currency reserve, as with gold bars. Ingots are made of metal, either pure or alloy, heated past its melting point and cast into a bar or block using a mold chill method. A special case are single crystal ingots made by pulling from a molten melt. Single crystal ingots of materials are grown using methods such as the Czochralski process or Bridgeman technique; the boules may be either semiconductors or non-conducting inorganic compounds for industrial and jewelry use. Single crystal ingots of metal are produced in similar fashion to that used to produce high purity semiconductor ingots, i.e. by vacuum induction refining.
Single crystal ingots of engineering metals are of interest due to their high strength due to lack of grain boundaries. The method of production is via single crystal dendrite and not via simple casting. Possible uses include turbine blades. In the United States, the brass and bronze ingot making industry started in the early 19th century; the US brass industry grew to be the number one producer by the 1850s. During colonial times the brass and bronze industries were non-existent because the British demanded all copper ore be sent to Britain for processing. Copper based alloy ingots weighed 20 pounds. Ingots are manufactured by the freezing of a molten liquid in a mold; the manufacture of ingots has several aims. Firstly, the mold is designed to solidify and form an appropriate grain structure required for processing, as the structure formed by the freezing melt controls the physical properties of the material. Secondly, the shape and size of the mold is designed to allow for ease of ingot handling and downstream processing.
The mold is designed to minimize melt wastage and aid ejection of the ingot, as losing either melt or ingot increases manufacturing costs of finished products. A variety of designs exist for the mold, which may be selected to suit the physical properties of the liquid melt and the solidification process. Molds may be fluted or flat walled; the fluted design increases heat transfer owing to a larger contact area. Molds may be either solid "massive" design, sand cast or water-cooled shells, depending upon heat transfer requirements. Ingot molds are tapered to prevent the formation of cracks due to uneven cooling. Crack or void formation occurs as the liquid to solid transition has an associated volume change for a constant mass of material. Formation of these ingot defects may render the cast ingot useless, may need to be re-melted, recycled or discarded; the physical structure of a crystalline material is determined by the method of cooling and precipitation of the molten metal. During the pouring process, metal in contact with the ingot walls cools and forms either a columnar structure, or a "chill zone" of equiaxed dendrites, depending upon the liquid being cooled and the cooling rate of the mold.
For a top-poured ingot, as the liquid cools within the mold, differential volume effects cause the top of the liquid to recede leaving a curved surface at the mold top which may be required to be machined from the ingot. The mold cooling effect creates an advancing solidification front, which has several associated zones, closer to the wall there is a solid zone which draws heat from the solidifying melt, for alloys there may exist a "mushy" zone, the result of solid-liquid equilibrium regions in the alloy's phase diagram, a liquid region; the rate of front advancement controls the time that dendrites or nuclei have to form in the solidification region. The width of the mushy zone in an alloy may be controlled by tuning the heat transfer properties of the mold, or adjusting the liquid melt alloy compositions. Continuous casting methods for ingot processing exist, whereby a stationary front of solidification is formed by the continual take-off of cooled solid material, the addition of molten liquid to the casting process.
70 percent of aluminium ingots in the U. S. are cast using the direct chill casting process. A total of 5 percent of ingots must be scrapped because of stress induced cracks and butt deformation. Plano-convex ingots are distributed archaeological artifacts which are studied to provide information on the history of metallurgy; the Chinese New Year food jiaozi was made to symbolize the ingot. The eighth letter in the Ogham alphabet is Tinne, meaning "ingot"; the title of Lindsey Davis' historical mystery crime novel, The Silver Pigs, refers to lead ingots from Roman Britain which feature prominently in the plot.

Borax known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, a salt of boric acid. Powdered borax is white, consisting of soft colorless crystals that dissolve in water. A number of related minerals or chemical compounds that differ in their crystal water content are referred to as borax, but the word is used to refer to the octahydrate. Commercially sold borax is dehydrated. Borax is a component of many detergents and enamel glazes, it is used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, as a precursor for other boron compounds, along with its inverse, boric acid, is useful as an insecticide. In artisanal gold mining, borax is sometimes used as part of a process meant to eliminate the need for toxic mercury in the gold extraction process, although it cannot directly replace mercury.
Borax was used by gold miners in parts of the Philippines in the 1900s. Borax was first discovered in dry lake beds in Tibet and was imported via the Silk Road to the Arabian Peninsula in the 8th century AD. Borax first came into common use in the late 19th century when Francis Marion Smith's Pacific Coast Borax Company began to market and popularize a large variety of applications under the 20 Mule Team Borax trademark, named for the method by which borax was hauled out of the California and Nevada deserts; the term borax is used for a number of related minerals or chemical compounds that differ in their crystal water content: anhydrous sodium tetraborate, Na2B4O7 sodium tetraborate pentahydrate, Na2B4O7·5H2O sodium tetraborate decahydrate, Na2B4O7·10H2O or equivalently the octahydrate, Na2B4O54·8H2OFrom the chemical perspective, borax contains the 2− ion. In this structure, there are two four-coordinate boron centers and two three-coordinate boron centers. Borax is easily converted to boric acid and other borates, which have many applications.
Its reaction with hydrochloric acid to form boric acid is: Na2B4O7·10H2O + 2 HCl → 4 B3 + 2 NaCl + 5 H2OThe "decahydrate" is sufficiently stable to find use as a primary standard for acid base titrimetry. When borax is added to a flame, it produces a yellow green color. Borax is not used for this purpose in fireworks due to the overwhelming yellow color of sodium. Boric acid is used to color methanol flames a transparent green. Borax is soluble in ethylene glycol, moderately soluble in diethylene glycol and methanol soluble in acetone, it is poorly soluble in cold water, but its solubility increases with temperature. The English word borax is Latinized: the Middle English form was boras, from Old French boras, bourras; that may have been from medieval Latin baurach, borax, along with Spanish borrax and Italian borrace, in the 9th century. Another name for borax is tincal, from Sanskrit; the word tincal "tinkle", or tincar "tinker", refers to crude borax, before it is purified, as mined from lake deposits in Tibet and other parts of Asia.
The word was adopted in the 17th century from Malay tingkal and from Urdu/Persian/Arabic تنکار tinkār/tankār. These all appear to be related to the Sanskrit टांकण ṭānkaṇa. Borax occurs in evaporite deposits produced by the repeated evaporation of seasonal lakes; the most commercially important deposits are found in: Turkey. Borax has been found at many other locations in the Southwestern United States, the Atacama desert in Chile, newly discovered deposits in Bolivia, in Tibet and Romania. Borax can be produced synthetically from other boron compounds. Occurring borax is refined by a process of recrystallization. Borax is used in various household laundry and cleaning products, including the "20 Mule Team Borax" laundry booster, "Boraxo" powdered hand soap, some tooth bleaching formulas. Borate ions are used in biochemical and chemical laboratories to make buffers, e.g. for polyacrylamide gel electrophoresis of DNA and RNA, such as TBE buffer or the newer SB buffer or BBS buffer in coating procedures.
Borate buffers are used as preferential equilibration solution in dimethyl pimelimidate based crosslinking reactions. Borax as a source of borate has been used to take advantage of the co-complexing ability of borate with other agents in water to form complex ions with various substances. Borate and a suitable polymer bed are used to chromatograph non-glycosylated hemoglobin differentially from glycosylated hemoglobin, an indicator of long term hyperglycemia in diabetes mellitus. Borax alone does not have a high affinity for the hardness cations, although it has been used for water-softening, its chemical equation for water-softening is given below: Ca2+ + Na2B4O7 → CaB4O7 ↓ + 2 Na+ Mg2+ + Na2B4O7 → MgB4O7 ↓ + 2 Na+ The sodium ions introduced do not make water ‘hard’. This method is suitable for removing both permanent types of hardness. A mixture of borax and ammonium chloride is used as a flux when welding steel, it lowers the melting point of the unwanted iron oxide. Borax is used mixed with water as a flux when soldering jewelry metals such as gold or silver, where it allows the molten solder to wet the metal and flow evenly int
Thomas Boulsover, was a Sheffield cutler, best remembered as the inventor of Sheffield Plate. He made his fortune manufacturing various items, but buttons using the process, he diversified into making cast steel and saws. Boulsover was born in Longley, a remote hamlet between the town of Sheffield and the village of Ecclesfield, He was the son of Samuel Boulsover, a farmer and cutler and Margaret Brownell of Hathersage, being baptised at Ecclesfield church on 18 October 1705, he began his apprenticeship to learn the trade of cutler in 1718, being apprenticed to Joseph Fletcher, a native of Wirksworth in Derbyshire who had established himself as a cutler in Sheffield. Fletcher was a Presbyterian and the young Boulsover would have been brought up with the same religious views as it was expected that an apprentice would join his master and family in their manner of worship. Thomas Boulsover's apprenticeship was completed in 1726 and he was granted the freedom of the Company of Cutlers in Hallamshire on 26 November of that year, the act being recorded in the Freedoms Book at the Cutlers' Hall.
As was traditional Boulsover was awarded his own trademark and this was registered in the Mark Book. Boulsover chose to practice as a free cutler in the developing township of Sheffield and on 28 October 1728 he married Hannah Dodworth of Owlerton at Sheffield parish church, they set up home in the Norfolk Street area where groups of cutlers were settling in newly built properties; the Boulsovers' first child Sarah was born in June 1729 but the infant soon died. Thomas Boulsover continued as a cutler, with several apprentices working for him over the years. In early 1743 Boulsover made the accidental discovery, to change his life and have an immense effect on the success and development of Sheffield. While repairing the decorative handle of a knife made from copper and silver he accidentally overheated the handle causing the two metals to fuse. Boulsover's initial despair at ruining a customer's expensive knife soon turned to elation when he realised the significance and potential of his find.
Boulsover experimented with his discovery of Sheffield Plate and found that when the silver and copper were fused together they could be treated as one metal, meaning that an ingot of copper fused with a layer of silver could be rolled to any area and thickness and still retain the same proportion of the two metals. This satisfied Boulsover that the fused metal could be modelled into any article and could be used on a commercial scale. Thomas Boulsover needed financial assistance to set up a business in fused plate and it came from Mr Strelley Pegge of Beauchief Hall who loaned him the necessary capital, he went into partnership with Joseph Wilson whose father was a scythe smith at Sharrow, setting up a workshop on Baker's Hill in Sheffield. The main product of the business was to make buttons from fused plate which would cost only a fraction of the cost of solid silver buttons. Boulsover's buttons were stamped from a die on a fused metal sheet cut out and burnished until they were hardly distinguishable from genuine silver.
The business made buckles and small snuff boxes. Joseph Wilson left the partnership in the mid 1740s, setting up his own business at Sharrow Mills making Sheffield plate items before diversifying into manufacturing snuff for which the Wilsons became World-famous. In 1749 Boulsover rented a lease of land in Beeley Wood to build a grinding wheel, but an alteration to the original lease allowed it to be converted into a tilt forge known as the Nova Scotia Tilts. Thomas Boulsover repaid the money loaned from Strelley Pegge and continued his enterprise with the help of two apprentices hiring John Hoyland as an agent to promote the sale of his buttons. Boulsover did not take out a patent on his discovery of Sheffield plate and Hoyland set up a business of his own making buttons and passed the secrets of the process on to others. Despite this competition, Boulsover's button business thrived. In 1751 Thomas was elected as one of the 24 assistants to the Master Cutler, however though he was re-elected as an assistant the following year he never rose any higher in the Company of Cutlers.
In 1757 he moved his business to larger premises on Norfolk Street, in the same year he bought Whiteley Wood Hall from his initial patron Strelley Pegge. Now a member of the gentry, Boulsover's guidance as a leading townsman was eagerly sought. In 1760 Boulsover turned his interest to manufacturing better quality steel, he purchased land from the Duke of Norfolk on the Porter Brook just below Whiteley Wood Hall and commenced rolling steel. He discovered that cast steel gave a much better edge to saws and concentrated on saw making, with his product being far superior to those made by the old method of hammering. In 1774 Boulsover & Co. based at Whiteley Woods and Norfolk Street, was described as “makers of saws, edge tools, cast steel and emory”. However button production continued at a site further up the Porter at Forge Dam, Fulwood. In 1772 Hannah Boulsover, Thomas's wife died and was buried in the churchyard of St Paul's Church on 9 July; the couple had been married for 44 years. As Thomas Boulsover grew older, he was helped by Anthony Thompson whom he had taken into partnership and who event
