102-611: White Lily is an American brand of all-purpose flour owned by the Hometown Food Company. White Lily was created by J. Allen Smith in Knoxville, Tennessee in 1883, and named after his wife, Lillie. Since Sunday dinner was a special occasion, bakers sometimes reserved its use specifically for that purpose, so it became known to some as the Sunday flour. It is a weak flour, containing 9% protein, which brings it closer to
204-471: A 14% moisture content. Thus, a US flour with 0.48% ash would approximate a French Type 55. Other measurable properties of flour as used in baking can be determined using a variety of specialized instruments, such as the farinograph . Flour dust suspended in air is explosive —as is any mixture of a finely powdered flammable substance with air ( see dust explosion ). Some devastating explosions have occurred at flour mills, including an explosion in 1878 at
306-400: A better way could be found to remove the seed. Eli Whitney responded to the challenge by inventing the inexpensive cotton gin . A man using a cotton gin could remove seed from as much upland cotton in one day as would previously have taken two months to process, working at the rate of one pound of cotton per day. These advances were capitalised on by entrepreneurs , of whom the best known
408-650: A bit more strength than cakes, but still produce flaky crusts rather than hard or crispy ones. All-purpose, or "AP flour", or plain flour is medium in gluten protein content at 9.5–11.5% (10–12% from second source ) protein content. It has adequate protein content for many bread and pizza bases, though bread flour and special 00 grade Italian flour are often preferred for these purposes, respectively, especially by artisan bakers. Some biscuits are also prepared using this type of flour. "Plain" refers not only to AP flour's middling gluten content but also to its lack of any added leavening agent (as in self-rising flour). Bread flour
510-520: A cottage industry under the putting-out system . Occasionally, the work was done in the workshop of a master weaver. Under the putting-out system, home-based workers produced under contract to merchant sellers, who often supplied the raw materials. In the off-season, the women, typically farmers' wives, did the spinning and the men did the weaving. Using the spinning wheel , it took anywhere from four to eight spinners to supply one handloom weaver. The flying shuttle , patented in 1733 by John Kay —with
612-604: A detailed account of the term. Economic historians and authors such as Mendels, Pomeranz , and Kridte argue that proto-industrialisation in parts of Europe, the Muslim world , Mughal India , and China created the social and economic conditions that led to the Industrial Revolution, thus causing the Great Divergence . Some historians, such as John Clapham and Nicholas Crafts , have argued that
714-403: A high proportion of starches , which are a subset of complex carbohydrates also known as polysaccharides . The kinds of flour used in cooking include all-purpose flour (known as plain outside North America), self-rising flour, and cake flour (including bleached flour). The higher the protein content the harder and stronger the flour, and the more it will produce crispy or chewy breads. The lower
816-489: A legal system that supported business; and financial capital available to invest. Once industrialisation began in Great Britain, new factors can be added: the eagerness of British entrepreneurs to export industrial expertise and the willingness to import the process. Britain met the criteria and industrialized starting in the 18th century, and then it exported the process to western Europe (especially Belgium, France, and
918-421: A mechanised industry. Other inventors increased the efficiency of the individual steps of spinning (carding, twisting and spinning, and rolling) so that the supply of yarn increased greatly. Steam power was then applied to drive textile machinery. Manchester acquired the nickname Cottonopolis during the early 19th century owing to its sprawl of textile factories. Although mechanisation dramatically decreased
1020-726: A more even thickness. The technology was developed with the help of John Wyatt of Birmingham . Paul and Wyatt opened a mill in Birmingham which used their rolling machine powered by a donkey. In 1743, a factory opened in Northampton with 50 spindles on each of five of Paul and Wyatt's machines. This operated until about 1764. A similar mill was built by Daniel Bourn in Leominster , but this burnt down. Both Lewis Paul and Daniel Bourn patented carding machines in 1748. Based on two sets of rollers that travelled at different speeds, it
1122-406: A number of subsequent improvements including an important one in 1747—doubled the output of a weaver, worsening the imbalance between spinning and weaving. It became widely used around Lancashire after 1760 when John's son, Robert , invented the dropbox, which facilitated changing thread colors. Lewis Paul patented the roller spinning frame and the flyer-and- bobbin system for drawing wool to

#17327933606221224-499: A pastry flour, producing lighter and fluffier biscuits. White Lily only uses the endosperm of flour grains, which is then bleached in chlorine, which both whitens the flour and weakens the proteins. Bags of White Lily are taller than most flour bags, as it weighs less per cup than standard all purpose flour due to using soft red winter wheat, which was once mostly grown in Georgia, South Carolina, North Carolina, and Tennessee. In 2018, it
1326-416: A relatively slow distribution system collided with natural shelf life . The reason for the limited shelf life is the fatty acids of the germ , which react from the moment they are exposed to oxygen. This occurs when grain is milled; the fatty acids oxidize and flour starts to become rancid . Depending on climate and grain quality, this process takes six to nine months. In the late 19th century, this process
1428-410: A reverberatory furnace, coal or coke could be used as fuel. The puddling process continued to be used until the late 19th century when iron was being displaced by mild steel. Because puddling required human skill in sensing the iron globs, it was never successfully mechanised. Rolling was an important part of the puddling process because the grooved rollers expelled most of the molten slag and consolidated
1530-438: A simple, wooden framed machine that only cost about £6 for a 40-spindle model in 1792 and was used mainly by home spinners. The jenny produced a lightly twisted yarn only suitable for weft, not warp. The spinning frame or water frame was developed by Richard Arkwright who, along with two partners, patented it in 1769. The design was partly based on a spinning machine built by Kay, who was hired by Arkwright. For each spindle
1632-458: A staple in the Americas. Rye flour is a constituent of bread in both Central Europe and Northern Europe . Cereal flour consists either of the endosperm , germ , and bran together (whole-grain flour) or of the endosperm alone (refined flour). Meal is either differentiable from flour as having slightly coarser particle size (degree of comminution ) or is synonymous with flour; the word
1734-569: A variety of cotton cloth, some of exceptionally fine quality. Cotton was a difficult raw material for Europe to obtain before it was grown on colonial plantations in the Americas. The early Spanish explorers found Native Americans growing unknown species of excellent quality cotton: sea island cotton ( Gossypium barbadense ) and upland green seeded cotton Gossypium hirsutum . Sea island cotton grew in tropical areas and on barrier islands of Georgia and South Carolina but did poorly inland. Sea island cotton began being exported from Barbados in
1836-548: A weight. The weights kept the twist from backing up before the rollers. The bottom rollers were wood and metal, with fluting along the length. The water frame was able to produce a hard, medium-count thread suitable for warp, finally allowing 100% cotton cloth to be made in Britain. Arkwright and his partners used water power at a factory in Cromford , Derbyshire in 1771, giving the invention its name. Samuel Crompton invented
1938-430: Is Arkwright. He is credited with a list of inventions, but these were actually developed by such people as Kay and Thomas Highs ; Arkwright nurtured the inventors, patented the ideas, financed the initiatives, and protected the machines. He created the cotton mill which brought the production processes together in a factory, and he developed the use of power—first horsepower and then water power—which made cotton manufacture
2040-488: Is a principal ingredient used to thicken many puddings or desserts, and is the main ingredient in packaged custard. Industrial Era The Industrial Revolution , sometimes divided into the First Industrial Revolution and Second Industrial Revolution , was a period of global transition of the human economy towards more widespread, efficient and stable manufacturing processes that succeeded
2142-400: Is a theoretically possible protein content ). This flour may be used where a recipe adds ingredients that require the dough to be extra strong to hold together in their presence, or when strength is needed for constructions of bread (e.g., some centerpiece displays). Gluten flour is refined gluten protein, or a theoretical 100% protein (though practical refining never achieves a full 100%). It
SECTION 20
#17327933606222244-422: Is flour where the germ is first separated from the endosperm and bran, then processed with steam, dry heat or microwave and blended into flour again. Milling of flour is accomplished by grinding grain between stones or steel wheels. Today, "stone-ground" usually means that the grain has been ground in a mill in which a revolving stone wheel turns over a stationary stone wheel, vertically or horizontally with
2346-416: Is often referred to as "white flour". Bleached flour is artificially aged using a "bleaching" agent, a "maturing" agent, or both. A bleaching agent affects the carotenoids responsible for the natural colour of the flour; a "maturing" agent also affects gluten development. A maturing agent may either strengthen or weaken gluten development. The four most common additives used as bleaching/maturing agents in
2448-457: Is treated either with benzoyl peroxide or chlorine gas, but no way exists to tell which process has been used when buying the flour at the grocery store. The old method of procuring white or "bleached" flour did not entail the use of chemical agents at all. Rather, the wheat kernels were moistened with water long enough for the outer kernels of the wheat which contained the bran to soften and, eventually, fall off while grinding. In some places,
2550-555: Is typically made from hard red winter wheat planted in the fall and harvested in the spring. Hard wheat is high in gluten, a protein that makes dough stretchy. Hard wheat is 11.5–13.5% (12–14% from second source ) protein. The increased protein binds to the flour to entrap carbon dioxide released by the yeast fermentation process, resulting in a better rise and chewier texture. Hard is a general term for flours with high gluten protein content, commonly refers to extra strong flour, with 13.5–16% (or 14–15% from some sources) protein (16%
2652-431: Is used both ways. For example, the word cornmeal often connotes a grittier texture whereas corn flour connotes fine powder, although there is no codified dividing line. The CDC has cautioned not to eat raw flour doughs or batters. Raw flour can contain bacteria like E. coli and needs to be cooked like other foods. The English word flour is originally a variant of the word flower , and both words derive from
2754-474: Is used to strengthen flour as needed. For example, adding approximately one teaspoon per cup of AP flour gives the resulting mix the protein content of bread flour. It is commonly added to whole grain flour recipes to overcome the tendency of greater fiber content to interfere with gluten development, needed to give the bread better rising (gas holding) qualities and chew. Unbleached flour is simply flour that has not undergone bleaching and therefore does not have
2856-613: The Agricultural Revolution . Beginning in Great Britain , the Industrial Revolution spread to continental Europe and the United States , from around 1760 to about 1820–1840. This transition included going from hand production methods to machines ; new chemical manufacturing and iron production processes; the increasing use of water power and steam power ; the development of machine tools ; and
2958-518: The Old French fleur or flour , which had the literal meaning "blossom", and a figurative meaning "the finest". The phrase fleur de farine meant "the finest part of the flour", since flour resulted from the elimination of coarse and unwanted matter from the grain during milling. Maize or corn flour has been important in Mesoamerican cuisine since ancient times and remains a staple in
3060-588: The Washburn "A" Mill in Minneapolis that killed 22 people. The CDC has cautioned not to eat raw flour doughs or batters. Raw flour can contain bacteria like E. coli and needs to be cooked like other foods. Bread , pasta , crackers , many cakes , and many other foods are made using flour. Wheat flour is also used to make a roux as a base for thickening gravy and sauces. It can also be used as an ingredient in papier-mâché glue . Cornstarch

Rapid economic growth began to reoccur after 1870, springing from a new group of innovations in what has been called the Second Industrial Revolution . These included new steel-making processes , mass production , assembly lines , electrical grid systems,

Crompton's mule was able to produce finer thread than hand spinning and at a lower cost. Mule-spun thread was of suitable strength to be used as a warp and finally allowed Britain to produce highly competitive yarn in large quantities. Realising that
3366-441: The 1650s. Upland green seeded cotton grew well on inland areas of the southern U.S. but was not economical because of the difficulty of removing seed, a problem solved by the cotton gin . A strain of cotton seed brought from Mexico to Natchez, Mississippi , in 1806 became the parent genetic material for over 90% of world cotton production today; it produced bolls that were three to four times faster to pick. The Age of Discovery
3468-439: The Americas. Rye flour is a constituent of bread in central and northern Europe. Archaeological evidence for making flour ( wheat seeds crushed between simple millstones ) dates to at least 6000 BC. In 2018, archaeologists reported finding evidence of bread making at Shubayqa 1, a Natufian hunter-gatherer site more than 14,000 years old in northwest Jordan. The Romans were the first to grind seeds on cone mills . In 1786, at

The commencement of the Industrial Revolution is closely linked to a small number of innovations, beginning in the second half of the 18th century. By the 1830s, the following gains had been made in important technologies: In 1750, Britain imported 2.5 million pounds of raw cotton, most of which
3672-496: The Indian industry. Bar iron was the commodity form of iron used as the raw material for making hardware goods such as nails, wire, hinges, horseshoes, wagon tires, chains, etc., as well as structural shapes. A small amount of bar iron was converted into steel. Cast iron was used for pots, stoves, and other items where its brittleness was tolerable. Most cast iron was refined and converted to bar iron, with substantial losses. Bar iron
3774-425: The Industrial Revolution began in Britain in the 1780s and was not fully felt until the 1830s or 1840s, while T. S. Ashton held that it occurred roughly between 1760 and 1830. Rapid adoption of mechanized textiles spinning occurred in Britain in the 1780s, and high rates of growth in steam power and iron production occurred after 1800. Mechanised textile production spread from Great Britain to continental Europe and
3876-577: The Scottish inventor James Beaumont Neilson in 1828, was the most important development of the 19th century for saving energy in making pig iron. By using preheated combustion air, the amount of fuel to make a unit of pig iron was reduced at first by between one-third using coke or two-thirds using coal; the efficiency gains continued as the technology improved. Hot blast also raised the operating temperature of furnaces, increasing their capacity. Using less coal or coke meant introducing fewer impurities into

4080-628: The United States in the early 19th century, with important centres of textiles, iron and coal emerging in Belgium and the United States and later textiles in France. An economic recession occurred from the late 1830s to the early 1840s when the adoption of the Industrial Revolution's early innovations, such as mechanised spinning and weaving, slowed as their markets matured; and despite the increasing adoption of locomotives, steamboats and steamships, and hot blast iron smelting . New technologies such as

Although Engels wrote his book in the 1840s, it was not translated into English until the late 19th century, and his expression did not enter everyday language until then. Credit for popularising the term may be given to Arnold Toynbee , whose 1881 lectures gave

4284-427: The ash mass is only rarely given on the label by flour manufacturers. However, the legally required standard nutrition label specifies the protein content of the flour, which is also a way for comparing the extraction rates of different available flour types. In general, as the extraction rate of the flour increases, so do both the protein and the ash content. However, as the extraction rate approaches 100% (whole meal),
4386-617: The beginning of the Industrial Era , the first steam-powered flour mill, Albion Mills, Southwark , was completed in London . In the 1930s, some flour began to be enriched with iron, niacin, thiamine and riboflavin. In the 1940s, mills started to enrich flour and folic acid was added to the list in the 1990s. An important problem of the Industrial Revolution was the preservation of flour. Transportation distances and

Cake flour is the lowest in gluten protein content, with 6–7% (5–8% from second source ) protein to produce minimal binding so the cake "crumbles" easily. Pastry flour has the second-lowest gluten protein content, with 7.5–9.5% (8–9% from second source ) protein to hold together with
4590-471: The coal do not migrate into the metal. This technology was applied to lead from 1678 and to copper from 1687. It was also applied to iron foundry work in the 1690s, but in this case the reverberatory furnace was known as an air furnace. (The foundry cupola is a different, and later, innovation.) Coke pig iron was hardly used to produce wrought iron until 1755–56, when Darby's son Abraham Darby II built furnaces at Horsehay and Ketley where low sulfur coal
4692-409: The coke pig iron he made was not suitable for making wrought iron and was used mostly for the production of cast iron goods, such as pots and kettles. He had the advantage over his rivals in that his pots, cast by his patented process, were thinner and cheaper than theirs. In 1750, coke had generally replaced charcoal in the smelting of copper and lead and was in widespread use in glass production. In
4794-447: The color of "white" flour. An example is graham flour , whose namesake, Sylvester Graham , was against using bleaching agents, which he considered unhealthy. In English-speaking countries, self-raising (or self-rising) flour is commercially available with chemical leavening agents already in the mix. In America, it is also likely to be pre-salted; in Britain this is not the case. The added ingredients are evenly distributed throughout
4896-467: The column of materials (iron ore, fuel, slag) flowing down the blast furnace more porous and did not crush in the much taller furnaces of the late 19th century. As cast iron became cheaper and widely available, it began being a structural material for bridges and buildings. A famous early example is the Iron Bridge built in 1778 with cast iron produced by Abraham Darby III. However, most cast iron
4998-495: The cost of cotton cloth, by the mid-19th century machine-woven cloth still could not equal the quality of hand-woven Indian cloth, in part because of the fineness of thread made possible by the type of cotton used in India, which allowed high thread counts. However, the high productivity of British textile manufacturing allowed coarser grades of British cloth to undersell hand-spun and woven fabric in low-wage India, eventually destroying
5100-487: The cotton textile industry in Britain was 2.6% in 1760, 17% in 1801, and 22.4% in 1831. Value added by the British woollen industry was 14.1% in 1801. Cotton factories in Britain numbered approximately 900 in 1797. In 1760, approximately one-third of cotton cloth manufactured in Britain was exported, rising to two-thirds by 1800. In 1781, cotton spun amounted to 5.1 million pounds, which increased to 56 million pounds by 1800. In 1800, less than 0.1% of world cotton cloth
5202-427: The country. Steam engines made the use of higher-pressure and volume blast practical; however, the leather used in bellows was expensive to replace. In 1757, ironmaster John Wilkinson patented a hydraulic powered blowing engine for blast furnaces. The blowing cylinder for blast furnaces was introduced in 1760 and the first blowing cylinder made of cast iron is believed to be the one used at Carrington in 1768 that

Six factors facilitated industrialisation: high levels of agricultural productivity, such as that reflected in the British Agricultural Revolution , to provide excess manpower and food; a pool of managerial and entrepreneurial skills; available ports, rivers, canals, and roads to cheaply move raw materials and outputs; natural resources such as coal, iron, and waterfalls; political stability and
5508-688: The entry for "Industry": "The idea of a new social order based on major industrial change was clear in Southey and Owen , between 1811 and 1818, and was implicit as early as Blake in the early 1790s and Wordsworth at the turn of the [19th] century." The term Industrial Revolution applied to technological change was becoming more common by the late 1830s, as in Jérôme-Adolphe Blanqui 's description in 1837 of la révolution industrielle .

In 1776, he patented a two-man operated loom. Cartwright's loom design had several flaws, the most serious being thread breakage. Samuel Horrocks patented a fairly successful loom in 1813. Horock's loom

6630-695: The major causes of the Industrial Revolution. Developments in law also facilitated the revolution, such as courts ruling in favour of property rights . An entrepreneurial spirit and consumer revolution helped drive industrialisation in Britain, which after 1800, was emulated in Belgium, the United States, and France. The Industrial Revolution marked a major turning point in history, comparable only to humanity's adoption of agriculture with respect to material advancement. The Industrial Revolution influenced in some way almost every aspect of daily life. In particular, average income and population began to exhibit unprecedented sustained growth. Some economists have said

A different use of rolling, which was done at lower temperatures than that for expelling slag, was in the production of iron sheets, and later structural shapes such as beams, angles, and rails. The puddling process was improved in 1818 by Baldwyn Rogers, who replaced some of the sand lining on the reverberatory furnace bottom with iron oxide . In 1838 John Hall patented

By 1600, Flemish refugees began weaving cotton cloth in English towns where cottage spinning and weaving of wool and linen was well established. They were left alone by the guilds who did not consider cotton a threat. Earlier European attempts at cotton spinning and weaving were in 12th-century Italy and 15th-century southern Germany, but these industries eventually ended when

According to Cambridge historian Leigh Shaw-Taylor, Britain was already industrialising in the 17th century, and "Our database shows that a groundswell of enterprise and productivity transformed the economy in the 17th century, laying the foundations for the world's first industrial economy. Britain was already a nation of makers by the year 1700" and "the history of Britain needs to be rewritten". Eric Hobsbawm held that

When flours do not contain gluten, they are suitable for people with gluten-related disorders , such as coeliac disease , non-celiac gluten sensitivity or wheat allergy sufferers, among others. Contamination with gluten-containing cereals can occur during grain harvesting, transporting, milling, storing, processing, handling and/or cooking. Flour also can be made from soybeans , arrowroot , taro , cattails , manioc , quinoa , and other non-cereal foodstuffs. In some markets,

The following table shows some typical examples of how protein and ash content relate to each other in wheat flour: This table is only a rough guideline for converting bread recipes. Since flour types are not standardized in many countries, the numbers may differ between manufacturers. There is no French type corresponding to
7650-429: The protein the softer the flour, which is better for cakes, cookies, and pie crusts. Cereal flour consists either of the endosperm , germ , and bran together (whole-grain flour) or of the endosperm alone (refined flour). "Bleached flour" is "refined" flour with a chemical whitening (bleaching) agent added. "Refined" flour has had the germ and bran, containing much of the nutritional fibre and vitamins, removed and
7752-437: The rise of the mechanised factory system . Output greatly increased, and the result was an unprecedented rise in population and the rate of population growth . The textile industry was the first to use modern production methods, and textiles became the dominant industry in terms of employment, value of output, and capital invested. Many of the technological and architectural innovations were of British origin. By
7854-418: The slag from almost 50% to around 8%. Puddling became widely used after 1800. Up to that time, British iron manufacturers had used considerable amounts of iron imported from Sweden and Russia to supplement domestic supplies. Because of the increased British production, imports began to decline in 1785, and by the 1790s Britain eliminated imports and became a net exporter of bar iron. Hot blast , patented by
7956-457: The smelting and refining of iron, coal and coke produced inferior iron to that made with charcoal because of the coal's sulfur content. Low sulfur coals were known, but they still contained harmful amounts. Conversion of coal to coke only slightly reduces the sulfur content. A minority of coals are coking. Another factor limiting the iron industry before the Industrial Revolution was the scarcity of water power to power blast bellows. This limitation
8058-424: The starchy endosperm is much lower than that of the outer parts of the grain. Flour made from all parts of the grain ( extraction rate : 100%) leaves about 2 grams (0.071 oz) ash or more per 100 grams (3.5 oz) dry flour. Plain white flour with an extraction rate of 50–60% leaves about 0.4 grams (0.014 oz). In the United States and the United Kingdom, no numbered standardized flour types are defined, and
8160-528: The supply of cotton was cut off. The Moors in Spain grew, spun, and wove cotton beginning around the 10th century. British cloth could not compete with Indian cloth because India's labour cost was approximately one-fifth to one-sixth that of Britain's. In 1700 and 1721, the British government passed Calico Acts to protect the domestic woollen and linen industries from the increasing amounts of cotton fabric imported from India. The demand for heavier fabric
8262-415: The use of low sulfur coal. The use of lime or limestone required higher furnace temperatures to form a free-flowing slag. The increased furnace temperature made possible by improved blowing also increased the capacity of blast furnaces and allowed for increased furnace height. In addition to lower cost and greater availability, coke had other important advantages over charcoal in that it was harder and made
8364-406: The use of roasted tap cinder ( iron silicate ) for the furnace bottom, greatly reducing the loss of iron through increased slag caused by a sand lined bottom. The tap cinder also tied up some phosphorus, but this was not understood at the time. Hall's process also used iron scale or rust which reacted with carbon in the molten iron. Hall's process, called wet puddling , reduced losses of iron with
8466-410: The water frame used a series of four pairs of rollers, each operating at a successively higher rotating speed, to draw out the fibre which was then twisted by the spindle. The roller spacing was slightly longer than the fibre length. Too close a spacing caused the fibres to break while too distant a spacing caused uneven thread. The top rollers were leather-covered and loading on the rollers was applied by
8568-505: Was 7,800 tons and coke cast iron was 250,000 tons. In 1750, the UK imported 31,200 tons of bar iron and either refined from cast iron or directly produced 18,800 tons of bar iron using charcoal and 100 tons using coke. In 1796, the UK was making 125,000 tons of bar iron with coke and 6,400 tons with charcoal; imports were 38,000 tons and exports were 24,600 tons. In 1806 the UK did not import bar iron but exported 31,500 tons. A major change in
8670-407: Was a means of decarburizing molten pig iron by slow oxidation in a reverberatory furnace by manually stirring it with a long rod. The decarburized iron, having a higher melting point than cast iron, was raked into globs by the puddler. When the glob was large enough, the puddler would remove it. Puddling was backbreaking and extremely hot work. Few puddlers lived to be 40. Because puddling was done in
8772-606: Was available (and not far from Coalbrookdale). These furnaces were equipped with water-powered bellows, the water being pumped by Newcomen steam engines . The Newcomen engines were not attached directly to the blowing cylinders because the engines alone could not produce a steady air blast. Abraham Darby III installed similar steam-pumped, water-powered blowing cylinders at the Dale Company when he took control in 1768. The Dale Company used several Newcomen engines to drain its mines and made parts for engines which it sold throughout
8874-414: Was converted to wrought iron. Conversion of cast iron had long been done in a finery forge . An improved refining process known as potting and stamping was developed, but this was superseded by Henry Cort 's puddling process. Cort developed two significant iron manufacturing processes: rolling in 1783 and puddling in 1784. Puddling produced a structural grade iron at a relatively low cost. Puddling
8976-566: Was cut off to eliminate competition. In order to promote manufacturing, the Crown paid for models of Lombe's machinery which were exhibited in the Tower of London . Parts of India, China, Central America, South America, and the Middle East have a long history of hand manufacturing cotton textiles, which became a major industry sometime after 1000 AD. In tropical and subtropical regions where it
9078-403: Was designed by John Smeaton . Cast iron cylinders for use with a piston were difficult to manufacture; the cylinders had to be free of holes and had to be machined smooth and straight to remove any warping. James Watt had great difficulty trying to have a cylinder made for his first steam engine. In 1774 Wilkinson invented a precision boring machine for boring cylinders. After Wilkinson bored
9180-399: Was developed in the mid-20th century. Modern farm equipment allows livestock farmers to do some or all of their own milling when it comes time to convert their own grain crops to coarse meal for livestock feed . This capability is economically important because the profit margins are often thin enough in commercial farming that saving expenses is vital to staying in business. Flour contains
9282-531: Was difficult to find north of Washington, D.C. but was more readily available as far west as Seattle , Washington and San Jose, California in 2020 during the Covid 19 Pandemic , possibly due to the company expanding retail operations with the loss of customers in the food industry. The J.M. Smucker Company bought the brand in 2006, shutting down the Knoxville mill in 2007 and moving production to two mills in
9384-544: Was followed by a period of colonialism beginning around the 16th century. Following the discovery of a trade route to India around southern Africa by the Portuguese, the British founded the East India Company , along with smaller companies of different nationalities which established trading posts and employed agents to engage in trade throughout the Indian Ocean region. One of the largest segments of this trade
9486-569: Was grown, most was grown by small farmers alongside their food crops and was spun and woven in households, largely for domestic consumption. In the 15th century, China began to require households to pay part of their taxes in cotton cloth. By the 17th century, almost all Chinese wore cotton clothing. Almost everywhere cotton cloth could be used as a medium of exchange . In India, a significant amount of cotton textiles were manufactured for distant markets, often produced by professional weavers. Some merchants also owned small weaving workshops. India produced
9588-479: Was improved by Richard Roberts in 1822, and these were produced in large numbers by Roberts, Hill & Co. Roberts was additionally a maker of high-quality machine tools and a pioneer in the use of jigs and gauges for precision workshop measurement. The demand for cotton presented an opportunity to planters in the Southern United States, who thought upland cotton would be a profitable crop if
9690-660: Was in cotton textiles, which were purchased in India and sold in Southeast Asia , including the Indonesian archipelago where spices were purchased for sale to Southeast Asia and Europe. By the mid-1760s, cloth was over three-quarters of the East India Company's exports. Indian textiles were in demand in the North Atlantic region of Europe where previously only wool and linen were available; however,
9792-400: Was later used in the first cotton spinning mill . In 1764, in the village of Stanhill, Lancashire, James Hargreaves invented the spinning jenny , which he patented in 1770. It was the first practical spinning frame with multiple spindles. The jenny worked in a similar manner to the spinning wheel, by first clamping down on the fibres, then by drawing them out, followed by twisting. It was
9894-437: Was made by the bloomery process, which was the predominant iron smelting process until the late 18th century. In the UK in 1720, there were 20,500 tons of cast iron produced with charcoal and 400 tons with coke. In 1750 charcoal iron production was 24,500 and coke iron was 2,500 tons. In 1788, the production of charcoal cast iron was 14,000 tons while coke iron production was 54,000 tons. In 1806, charcoal cast iron production
9996-419: Was met by a domestic industry based around Lancashire that produced fustian , a cloth with flax warp and cotton weft . Flax was used for the warp because wheel-spun cotton did not have sufficient strength, but the resulting blend was not as soft as 100% cotton and was more difficult to sew. On the eve of the Industrial Revolution, spinning and weaving were done in households, for domestic consumption, and as
10098-413: Was overcome by the steam engine. Use of coal in iron smelting started somewhat before the Industrial Revolution, based on innovations by Clement Clerke and others from 1678, using coal reverberatory furnaces known as cupolas. These were operated by the flames playing on the ore and charcoal or coke mixture, reducing the oxide to metal. This has the advantage that impurities (such as sulphur ash) in
10200-425: Was produced on machinery invented in Britain. In 1788, there were 50,000 spindles in Britain, rising to 7 million over the next 30 years. The earliest European attempts at mechanised spinning were with wool; however, wool spinning proved more difficult to mechanise than cotton. Productivity improvement in wool spinning during the Industrial Revolution was significant but far less than that of cotton. Arguably
10302-686: Was spun and woven by the cottage industry in Lancashire . The work was done by hand in workers' homes or occasionally in master weavers' shops. Wages in Lancashire were about six times those in India in 1770 when overall productivity in Britain was about three times higher than in India. In 1787, raw cotton consumption was 22 million pounds, most of which was cleaned, carded, and spun on machines. The British textile industry used 52 million pounds of cotton in 1800, which increased to 588 million pounds in 1850. The share of value added by
10404-435: Was too short for an industrial production and distribution cycle. As vitamins , micronutrients and amino acids were completely or relatively unknown in the late 19th century, removing the germ was an effective solution. Without the germ, flour cannot become rancid. Degermed flour became standard. Degermation started in densely populated areas and took approximately one generation to reach the countryside. Heat-processed flour
