Slovakia the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, the Czech Republic to the northwest. Slovakia's territory spans about 49,000 square kilometres and is mountainous; the population is over 5.4 million and consists of Slovaks. The capital and largest city is Bratislava, the second largest city is Košice; the official language is Slovak. The Slavs arrived in the territory of present-day Slovakia in the 6th centuries. In the 7th century, they played a significant role in the creation of Samo's Empire and in the 9th century established the Principality of Nitra, conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which would become the Kingdom of Hungary in 1000. In 1241 and 1242, much of the territory was destroyed by the Mongols during their invasion of Central and Eastern Europe.
The area was recovered thanks to Béla IV of Hungary who settled Germans which became an important ethnic group in the area in what are today parts of central and eastern Slovakia. After World War I and the dissolution of the Austro-Hungarian Empire, the Czechoslovak National Council established Czechoslovakia. A separate Slovak Republic existed during World War II as a totalitarian, clero-fascist one-party client state of Nazi Germany. At the end of World War II, Czechoslovakia was re-established as an independent country. A coup in 1948 ushered in a totalitarian one-party state under the Communist regime during whose rule the country existed as a satellite of the Soviet Union. Attempts for liberalization of communism in Czechoslovakia culminated in the Prague Spring, crushed by the Warsaw Pact invasion of Czechoslovakia in August 1968. In 1989, the Velvet Revolution ended the Communist rule in Czechoslovakia peacefully. Slovakia became an independent state on 1 January 1993 after the peaceful dissolution of Czechoslovakia, sometimes known as the Velvet Divorce.
Slovakia is a developed country, with a high-income advanced economy and a high Human Development Index, a high standard of living and performs favourably in measurements of civil liberties, press freedom, internet freedom, democratic governance and peacefulness. The country maintains a combination of market economy with a comprehensive social security system. Citizens of Slovakia are provided with universal health care, free education and one of the longest paid parental leave in the OECD; the country joined the European Union on 1 May 2004 and joined the Eurozone on 1 January 2009. Slovakia is a member of the Schengen Area, NATO, the United Nations, the OECD, the WTO, CERN, the OSCE, the Council of Europe and the Visegrád Group. Although regional income inequality is high, 90% of citizens own their homes. In 2018, Slovak citizens had visa-free or visa-on-arrival access to 179 countries and territories, ranking the Slovak passport 10th in the world; as part of Eurozone, Slovak legal tender is the world's 2nd-most-traded currency.
Slovakia is the world's largest per-capita car producer with a total of 1,040,000 cars manufactured in the country in 2016 alone and the 7th largest car producer in the European Union. The car industry represents 43% of Slovakia's industrial output, a quarter of its exports; the first written mention of name Slovakia is in 1586. It derives from the Czech word Slováky; the native name Slovensko derives from an older name of Slovaks Sloven what may indicate its origin before the 15th century. The original meaning was geographic, since Slovakia was a part of the multiethnic Kingdom of Hungary and did not form a separate administrative unit in this period. Radiocarbon dating puts the oldest surviving archaeological artefacts from Slovakia – found near Nové Mesto nad Váhom – at 270,000 BCE, in the Early Paleolithic era; these ancient tools, made by the Clactonian technique, bear witness to the ancient habitation of Slovakia. Other stone tools from the Middle Paleolithic era come from the Prévôt cave in Bojnice and from other nearby sites.
The most important discovery from that era is a Neanderthal cranium, discovered near Gánovce, a village in northern Slovakia. Archaeologists have found prehistoric human skeletons in the region, as well as numerous objects and vestiges of the Gravettian culture, principally in the river valleys of Nitra, Ipeľ, Váh and as far as the city of Žilina, near the foot of the Vihorlat and Tribeč mountains, as well as in the Myjava Mountains; the most well-known finds include the oldest female statue made of mammoth-bone, the famous Venus of Moravany. The statue was found in the 1940s in Moravany nad Váhom near Piešťany. Numerous necklaces made of shells from Cypraca thermophile gastropods of the Tertiary period have come from the sites of Zákovská, Podkovice and Radošina; these findings provide the most ancient evidence of commercial exchanges carried out between the Mediterranean and central Europe. The Bronze Age in the geographical territory of modern-day Slovakia went through three stages of development, stretching from 2000 to 800 BCE.
Major cultural and political development can be attributed to the significant growth in production of copper in central Slovakia and northwe
Denmark the Kingdom of Denmark, is a Nordic country and the southernmost of the Scandinavian nations. Denmark lies southwest of Sweden and south of Norway, is bordered to the south by Germany; the Kingdom of Denmark comprises two autonomous constituent countries in the North Atlantic Ocean: the Faroe Islands and Greenland. Denmark proper consists of a peninsula, an archipelago of 443 named islands, with the largest being Zealand and the North Jutlandic Island; the islands are characterised by flat, arable land and sandy coasts, low elevation and a temperate climate. Denmark has a total area of 42,924 km2, land area of 42,394 km2, the total area including Greenland and the Faroe Islands is 2,210,579 km2, a population of 5.8 million. The unified kingdom of Denmark emerged in the 10th century as a proficient seafaring nation in the struggle for control of the Baltic Sea. Denmark and Norway were ruled together under one sovereign ruler in the Kalmar Union, established in 1397 and ending with Swedish secession in 1523.
The areas of Denmark and Norway remained under the same monarch until Denmark -- Norway. Beginning in the 17th century, there were several devastating wars with the Swedish Empire, ending with large cessions of territory to Sweden. After the Napoleonic Wars, Norway was ceded to Sweden, while Denmark kept the Faroe Islands and Iceland. In the 19th century there was a surge of nationalist movements, which were defeated in the 1864 Second Schleswig War. Denmark remained neutral during World War I. In April 1940, a German invasion saw brief military skirmishes while the Danish resistance movement was active from 1943 until the German surrender in May 1945. An industrialised exporter of agricultural produce in the second half of the 19th century, Denmark introduced social and labour-market reforms in the early 20th century that created the basis for the present welfare state model with a developed mixed economy; the Constitution of Denmark was signed on 5 June 1849, ending the absolute monarchy, which had begun in 1660.
It establishes a constitutional monarchy organised as a parliamentary democracy. The government and national parliament are seated in Copenhagen, the nation's capital, largest city, main commercial centre. Denmark exercises hegemonic influence in the Danish Realm, devolving powers to handle internal affairs. Home rule was established in the Faroe Islands in 1948. Denmark negotiated certain opt-outs, it is among the founding members of NATO, the Nordic Council, the OECD, OSCE, the United Nations. Denmark is considered to be one of the most economically and developed countries in the world. Danes enjoy a high standard of living and the country ranks in some metrics of national performance, including education, health care, protection of civil liberties, democratic governance and human development; the country ranks as having the world's highest social mobility, a high level of income equality, is among the countries with the lowest perceived levels of corruption in the world, the eleventh-most developed in the world, has one of the world's highest per capita incomes, one of the world's highest personal income tax rates.
The etymology of the word Denmark, the relationship between Danes and Denmark and the unifying of Denmark as one kingdom, is a subject which attracts debate. This is centered on the prefix "Dan" and whether it refers to the Dani or a historical person Dan and the exact meaning of the -"mark" ending. Most handbooks derive the first part of the word, the name of the people, from a word meaning "flat land", related to German Tenne "threshing floor", English den "cave"; the -mark is believed to mean woodland or borderland, with probable references to the border forests in south Schleswig. The first recorded use of the word Danmark within Denmark itself is found on the two Jelling stones, which are runestones believed to have been erected by Gorm the Old and Harald Bluetooth; the larger stone of the two is popularly cited as Denmark's "baptismal certificate", though both use the word "Denmark", in the form of accusative ᛏᛅᚾᛘᛅᚢᚱᚴ tanmaurk on the large stone, genitive ᛏᛅᚾᛘᛅᚱᚴᛅᚱ "tanmarkar" on the small stone.
The inhabitants of Denmark are there called "Danes", in the accusative. The earliest archaeological findings in Denmark date back to the Eem interglacial period from 130,000–110,000 BC. Denmark has been inhabited since around 12,500 BC and agriculture has been evident since 3900 BC; the Nordic Bronze Age in Denmark was marked by burial mounds, which left an abundance of findings including lurs and the Sun Chariot. During the Pre-Roman Iron Age, native groups began migrating south, the first tribal Danes came to the country between the Pre-Roman and the Germanic Iron Age, in the Roman Iron Age; the Roman provinces maintained trade routes and relations with native tribes in Denmark, Roman coins have been found in Denmark. Evidence of strong Celtic cultural influence dates from this period in Denmark and much of North-West Europe and is among other things reflected in the finding of the Gundestrup cauldron; the tribal Danes came from the east Danish islands and Scania and spoke an early form of North Germanic.
Historians believe that before their arrival, most of Jutland and the nearest islands were settled by tribal J
A printing press is a mechanical device for applying pressure to an inked surface resting upon a print medium, thereby transferring the ink. It marked a dramatic improvement on earlier printing methods in which the cloth, paper or other medium was brushed or rubbed to achieve the transfer of ink, accelerated the process. Used for texts, the invention and global spread of the printing press was one of the most influential events in the second millennium. Johannes Gutenberg, a goldsmith by profession, circa 1439, a printing system by adapting existing technologies to printing purposes, as well as making inventions of his own. Printing in East Asia had been prevalent since the Tang dynasty, in Europe, woodblock printing based on existing screw presses was common by the 14th century. Gutenberg's most important innovation was the development of hand-molded metal printing matrices, thus producing a movable type-based printing press system, his newly devised hand mould made possible the precise and rapid creation of metal movable type in large quantities.
Movable type had been hitherto unknown in Europe. In Europe, the two inventions, the hand mould and the printing press, together drastically reduced the cost of printing books and other documents in short print runs; the printing press spread within several decades to over two hundred cities in a dozen European countries. By 1500, printing presses in operation throughout Western Europe had produced more than twenty million volumes. In the 16th century, with presses spreading further afield, their output rose tenfold to an estimated 150 to 200 million copies; the operation of a press became synonymous with the enterprise of printing, lent its name to a new medium of expression and communication, "the press". In Renaissance Europe, the arrival of mechanical movable type printing introduced the era of mass communication, which permanently altered the structure of society; the unrestricted circulation of information and ideas transcended borders, captured the masses in the Reformation and threatened the power of political and religious authorities.
The sharp increase in literacy broke the monopoly of the literate elite on education and learning and bolstered the emerging middle class. Across Europe, the increasing cultural self-awareness of its peoples led to the rise of proto-nationalism, accelerated by the development of European vernacular languages, to the detriment of Latin's status as lingua franca. In the 19th century, the replacement of the hand-operated Gutenberg-style press by steam-powered rotary presses allowed printing on an industrial scale; the rapid economic and socio-cultural development of late medieval society in Europe created favorable intellectual and technological conditions for Gutenberg's improved version of the printing press: the entrepreneurial spirit of emerging capitalism made its impact on medieval modes of production, fostering economic thinking and improving the efficiency of traditional work-processes. The sharp rise of medieval learning and literacy amongst the middle class led to an increased demand for books which the time-consuming hand-copying method fell far short of accommodating.
Technologies preceding the press that led to the press's invention included: manufacturing of paper, development of ink, woodblock printing, distribution of eyeglasses. At the same time, a number of medieval products and technological processes had reached a level of maturity which allowed their potential use for printing purposes. Gutenberg took up these far-flung strands, combined them into one complete and functioning system, perfected the printing process through all its stages by adding a number of inventions and innovations of his own: The screw press which allowed direct pressure to be applied on flat-plane was of great antiquity in Gutenberg's time and was used for a wide range of tasks. Introduced in the 1st century AD by the Romans, it was employed in agricultural production for pressing wine grapes and oil fruit, both of which formed an integral part of the mediterranean and medieval diet; the device was used from early on in urban contexts as a cloth press for printing patterns.
Gutenberg may have been inspired by the paper presses which had spread through the German lands since the late 14th century and which worked on the same mechanical principles. Gutenberg adopted the basic design. Printing, put a demand on the machine quite different from pressing. Gutenberg adapted the construction so that the pressing power exerted by the platen on the paper was now applied both evenly and with the required sudden elasticity. To speed up the printing process, he introduced a movable undertable with a plane surface on which the sheets could be swiftly changed; the concept of movable type was not new in the 15th century. In Europe, sporadic evidence that the typographical principle, the idea of creating a text by reusing individual characters, was well understood and employed in pre-Gutenberg Europe had been cropping up since the 12th century and before; the known examples range from Germany to England to Italy. However, the various techniques employed did not have the refinement and efficiency needed to become accepted.
Gutenberg improved the process by treating typesetting and printing as two separate work steps. A goldsmith by profession, he created his type pieces from a lead-based alloy
Henry Ford was an American captain of industry and a business magnate, the founder of the Ford Motor Company, the sponsor of the development of the assembly line technique of mass production. Although Ford did not invent the automobile or the assembly line, he developed and manufactured the first automobile that many middle-class Americans could afford. In doing so, Ford converted the automobile from an expensive curiosity into a practical conveyance that would profoundly impact the landscape of the 20th century, his introduction of the Model T automobile revolutionized American industry. As the owner of the Ford Motor Company, he became one of the richest and best-known people in the world, he is credited with "Fordism": mass production of inexpensive goods coupled with high wages for workers. Ford had a global vision, with consumerism as the key to peace, his intense commitment to systematically lowering costs resulted in many technical and business innovations, including a franchise system that put dealerships throughout most of North America and in major cities on six continents.
Ford left most of his vast wealth to the Ford Foundation and arranged for his family to control the company permanently. Ford was widely known for his pacifism during the first years of World War I, for promoting antisemitic content, including The Protocols of the Elders of Zion, through his newspaper The Dearborn Independent and the book The International Jew, having an influence on the development of Nazism and Adolf Hitler. Henry Ford was born July 1863, on a farm in Greenfield Township, Michigan, his father, William Ford, was born in County Cork, Ireland, to a family, from Somerset, England. His mother, Mary Ford, was born in Michigan as the youngest child of Belgian immigrants. Henry Ford's siblings were Margaret Ford, his father gave him a pocket watch in his early teens. At 15, Ford dismantled and reassembled the timepieces of friends and neighbors dozens of times, gaining the reputation of a watch repairman. At twenty, Ford walked four miles to their Episcopal church every Sunday. Ford was devastated when his mother died in 1876.
His father expected him to take over the family farm, but he despised farm work. He wrote, "I never had any particular love for the farm—it was the mother on the farm I loved."In 1879, Ford left home to work as an apprentice machinist in Detroit, first with James F. Flower & Bros. and with the Detroit Dry Dock Co. In 1882, he returned to Dearborn to work on the family farm, where he became adept at operating the Westinghouse portable steam engine, he was hired by Westinghouse to service their steam engines. During this period Ford studied bookkeeping at Goldsmith, Bryant & Stratton Business College in Detroit. Ford married Clara Jane Bryant on April 11, 1888, supported himself by farming and running a sawmill, they had one child: Edsel Ford. In 1891, Ford became an engineer with the Edison Illuminating Company of Detroit. After his promotion to Chief Engineer in 1893, he had enough time and money to devote attention to his personal experiments on gasoline engines; these experiments culminated in 1896 with the completion of a self-propelled vehicle which he named the Ford Quadricycle.
He test-drove it on June 4. After various test drives, Ford brainstormed ways to improve the Quadricycle. In 1896, Ford attended a meeting of Edison executives, where he was introduced to Thomas Edison. Edison approved of Ford's automobile experimentation. Encouraged by Edison, Ford designed and built a second vehicle, completing it in 1898. Backed by the capital of Detroit lumber baron William H. Murphy, Ford resigned from the Edison Company and founded the Detroit Automobile Company on August 5, 1899. However, the automobiles produced were of higher price than Ford wanted; the company was not successful and was dissolved in January 1901. With the help of C. Harold Wills, Ford designed and raced a 26-horsepower automobile in October 1901. With this success and other stockholders in the Detroit Automobile Company formed the Henry Ford Company on November 30, 1901, with Ford as chief engineer. In 1902, Murphy brought in Henry M. Leland as a consultant. With Ford gone, Murphy renamed the company the Cadillac Automobile Company.
Teaming up with former racing cyclist Tom Cooper, Ford produced the 80+ horsepower racer "999" which Barney Oldfield was to drive to victory in a race in October 1902. Ford received the backing of an old acquaintance, Alexander Y. Malcomson, a Detroit-area coal dealer, they formed a partnership, "Ltd." to manufacture automobiles. Ford went to work designing an inexpensive automobile, the duo leased a factory and contracted with a machine shop owned by John and Horace E. Dodge to supply over $160,000 in parts. Sales were slow, a crisis arose when the Dodge brothers demanded payment for their first shipment. In response, Malcomson brought in another group of investors and convinced the Dodge Brothers to accept a portion of the new company. Ford & Malcomson was reincorporated as the Ford Motor Company on June 16, 1903, with $28,000 capital; the original investors included Ford and Malcomson, the Dodge brothers, Malcomson's uncle John S. Gray, Malcolmson's secretary James Couzens, two of Malcomson's lawyers, John W. Anderson and Horace Rackham.
Ford demonstrated a newly designed car on the ice of Lake St. Clair, driving 1 mile in 39.4 seconds and setting a ne
Pottery is the process of forming vessels and other objects with clay and other ceramic materials, which are fired to give them a hard, durable form. Major types include earthenware and porcelain; the place where such wares are made by a potter is called a pottery. The definition of pottery used by the American Society for Testing and Materials, is "all fired ceramic wares that contain clay when formed, except technical and refractory products." In archaeology of ancient and prehistoric periods, "pottery" means vessels only, figures etc. of the same material are called "terracottas". Clay as a part of the materials used is required by some definitions of pottery, but this is dubious. Pottery is one of the oldest human inventions, originating before the Neolithic period, with ceramic objects like the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC, pottery vessels that were discovered in Jiangxi, which date back to 18,000 BC.
Early Neolithic pottery artefacts have been found in places such as Jōmon Japan, the Russian Far East, Sub-Saharan Africa and South America. Pottery is made by forming a ceramic body into objects of a desired shape and heating them to high temperatures in a kiln and induces reactions that lead to permanent changes including increasing the strength and solidity of the object's shape. Much pottery is purely utilitarian, but much can be regarded as ceramic art. A clay body can be decorated after firing. Clay-based pottery can divided in three main groups: earthenware and porcelain; these require more specific clay material, higher firing temperatures. All three are made for different purposes. All may be decorated by various techniques. In many examples the group a piece belongs to is visually apparent, but this is not always the case; the fritware of the Islamic world does not use clay, so technically falls outside these groups. Historic pottery of all these types is grouped as either "fine" wares expensive and well-made, following the aesthetic taste of the culture concerned, or alternatively "coarse", "popular" "folk" or "village" wares undecorated, or so, less well-made.
All the earliest forms of pottery were made from clays that were fired at low temperatures in pit-fires or in open bonfires. They were hand undecorated. Earthenware can be fired as low as 600°C, is fired below 1200°C; because unglazed biscuit earthenware is porous, it has limited utility for the storage of liquids, eating off. However, earthenware has a continuous history from the Neolithic period to today, it can be made from a wide variety of clays, some of which fire to a buff, brown or black colour, with iron in the constituent minerals resulting in a reddish-brown. Reddish coloured varieties are called terracotta when unglazed or used for sculpture; the development of ceramic glaze which makes it impermeable makes it a popular and practical form of pottery. The addition of decoration has evolved throughout its history. Stoneware is pottery, fired in a kiln at a high temperature, from about 1,100°C to 1,200°C, is stronger and non-porous to liquids; the Chinese, who developed stoneware early on, classify this together with porcelain as high-fired wares.
In contrast, stoneware could only be produced in Europe from the late Middle Ages, as European kilns were less efficient, the right sorts of clay less common. It remained a speciality of Germany until the Renaissance. Stoneware is tough and practical, much of it has always been utilitarian, for the kitchen or storage rather than the table, but "fine" stoneware has been important in China and the West, continues to be made. Many utilitarian types have come to be appreciated as art. Porcelain is made by heating materials including kaolin, in a kiln to temperatures between 1,200 and 1,400 °C; this is higher than used for the other types, achieving these temperatures was a long struggle, as well as realizing what materials were needed. The toughness and translucence of porcelain, relative to other types of pottery, arises from vitrification and the formation of the mineral mullite within the body at these high temperatures. Although porcelain was first made in China, the Chinese traditionally do not recognise it as a distinct category, grouping it with stoneware as "high-fired" ware, opposed to "low-fired" earthenware.
This confuses the issue of. A degree of translucency and whiteness was achieved by the Tang Dynasty, considerable quantities were being exported; the modern level of whiteness was not reached until much in the 14th century. Porcelain was made in Korea and in Japan from the end of the 16th century, after suitable kaolin was located in those countries, it was not made outside East Asia until the 18th century. Before being shaped, clay must be prepared. Kneading helps to ensure an moisture content throughout the body. Air trapped within the clay body needs to be removed; this is called de-airing and can be accomplished either by a machine called a vacuum pug or manually by wedging. Wedging can help produce an moisture content. Once a clay body has been kneaded and de-aired or wedged, it is shaped by a variety of techniques. After it has been shaped, it is dried and fired. Greenware refers to unfired objects. At sufficient moisture content, bodies at this stage are in their most plastic form (as they are soft and mal
Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place. Tanning hide into leather involves a process which permanently alters the protein structure of skin, making it more durable and less susceptible to decomposition, possibly coloring it. Before tanning, the skins are unhaired, degreased and soaked in water over a period of 6 hours to 2 days; this process was considered a noxious or "odoriferous trade" and relegated to the outskirts of town. Traditionally, tanning used tannin, an acidic chemical compound from which the tanning process draws its name; the use of a chromium solution was adopted by tanners in the Industrial Revolution. The English word for tanning is from medieval Latin tannāre, deriv. of tannum, from French tan, from old-Cornish tann. These terms are related to a hypothetical dʰonu meaning fir tree in Proto-Indo-European.. Despite the linguistic confusion between quite different conifers and oaks, the word tan referring to dyes and types of hide preservation is from the Gaulic use referencing the bark of oaks, not fir trees.
Ancient civilizations used leather for waterskins, bags and tack, armour, scabbards and sandals. Tanning was being carried out by the inhabitants of Mehrgarh in Pakistan between 7000 and 3300 BC. Around 2500 BC, the Sumerians began using leather, affixed by copper studs, on chariot wheels. Tanning was considered a noxious or "odoriferous trade" and relegated to the outskirts of town, amongst the poor. Indeed, tanning by ancient methods is so foul smelling, tanneries are still isolated from those towns today where the old methods are used. Skins arrived at the tannery dried stiff and dirty with soil and gore. First, the ancient tanners would soak the skins in water to soften them, they would pound and scour the skin to remove any remaining flesh and fat. Next, the tanner needed to remove the hair from the skin; this was done by either soaking the skin in urine, painting it with an alkaline lime mixture, or allowing the skin to putrefy for several months dipping it in a salt solution. After the hairs were loosened, the tanners scraped them off with a knife.
Once the hair was removed, the tanners would "bate" the material by pounding dung into the skin, or soaking the skin in a solution of animal brains. Bating was a fermentative process. Among the kinds of dung used were those of dogs or pigeons; the actual tanning process used vegetable tanning. In some variations of the process, cedar oil, alum, or tannin were applied to the skin as a tanning agent; as the skin was stretched, it would absorb the agent. Following the adoption in medicine of soaking gut sutures in a chromium solution after 1840, it was discovered that this method could be used with leather and thus was adopted by tanners; the tanning process begins with obtaining an animal skin. When an animal skin is to be tanned, the animal is killed and skinned before the body heat leaves the tissues; this can be done by the tanner, or by obtaining a skin at a slaughterhouse, farm, or local fur trader. Preparing hides begins by curing them with salt. Curing is employed to prevent putrefaction of the protein substance from bacterial growth during the time lag from procuring the hide to when it is processed.
Curing removes water from the skins using a difference in osmotic pressure. The moisture content of hides and skins is reduced, osmotic pressure increased, to the point that bacteria are unable to grow. In wet-salting, the hides are salted pressed into packs for about 30 days. In brine-curing, the hides are agitated in a saltwater bath for about 16 hours. Curing can be accomplished by preserving the hides and skins at low temperatures; the steps in the production of leather between curing and tanning are collectively referred to as beamhouse operations. They include, in order, liming, removal of extraneous tissues, bating or puering and pickling. In soaking, the hides are soaked in clean water to remove the salt left over from curing and increase the moisture so that the hide or skin can be further treated. To prevent damage of the skin by bacterial growth during the soaking period, biocides dithiocarbamates, may be used. Fungicides such as 2-thiocyanomethylthiobenzothiazole may be added in the process, to protect wet leathers from mold growth.
After 1980, the use of pentachlorophenol and mercury-based biocides and their derivatives was forbidden. After soaking, the hides and skins are taken for liming: treatment with milk of lime that may involve the addition of "sharpening agents" such as sodium sulfide, amines, etc; the objectives of this operation are to: Remove the hair and other keratinous matter Remove some of the interfibrillary soluble proteins such as mucins Swell up and split up the fibres to the desired extent Remove the natural grease and fats to some extent Bring the collagen in the hide to a proper condition for satisfactory tannageThe weakening of hair is dependent on the breakdown of the disulfide link of the amino acid cystine, the characteristic of the keratin class of proteins that gives strength to hair and wools.

Skansen is the first open-air museum and zoo in Sweden and is located on the island Djurgården in Stockholm, Sweden. It was opened on 11 October 1891 by Artur Hazelius to show the way of life in the different parts of Sweden before the industrial era; the name "Skansen" has been used as a noun to refer to other open-air museums and collections of historic structures in Central and Eastern Europe, but in the United States, e.g. Old World Wisconsin and Fairplay, Colorado; the 19th century was a period of great change throughout Europe, Sweden was no exception. Its rural way of life was giving way to an industrialised society and many feared that the country's many traditional customs and occupations might be lost to history. Artur Hazelius, who had founded the Nordic Museum on the island of Djurgården near the centre of Stockholm, was inspired by the open-air museum, founded by King Oscar II in Kristiania in 1881, when he created his open-air museum on the hill that dominates the island. Skansen became the model for other early open-air museums in Scandinavia and ones elsewhere.
Skansen was a part of the Nordic Museum, but became an independent organisation in 1963. The objects within the Skansen buildings are still the property of the Nordic Museum. After extensive travelling, Hazelius bought around 150 houses from all over the country and had them shipped piece by piece to the museum, where they were rebuilt to provide a unique picture of traditional Sweden. Only three of the buildings in the museum are not original, were painstakingly copied from examples he had found. All of the buildings are open to visitors and show the full range of Swedish life from the Skogaholm Manor house built in 1680, to the 16th century Älvros farmhouses. Skansen attracts more than 1.3 million visitors each year. The many exhibits over the 75 acre site include a full replica of an average 19th-century town, in which craftsmen in traditional dress such as tanners, silversmiths and glass-blowers demonstrate their skills in period surroundings. There is a small patch growing tobacco used for the making of cigarettes.
There is an open-air zoo containing a wide range of Scandinavian animals including the bison, brown bear, grey seal, otter, red fox, reindeer and wolverine. There are farmsteads where rare breeds of farm animals can be seen. In early December the site's central Bollnäs square is host to a popular Christmas market, held since 1903, attracting around 25,000 visitors each weekend. In the summer there are displays of folk dancing and concerts. Since 1897, Skansen has been served by the Skansens Bergbana, a funicular railway on the northwest side of the Skansen hill; the funicular is 196.4 meters long, with a total rise of 34.57 meters. Skansen is served by modern and vintage trams on line 7.
