When a mound is completed, and the ground around has been swept clean of residual combustible material, a senior potter lights the fire. A handful of grass is lit, and the woman runs around the circumference of the mound, touching the burning torch to the dried grass. Some mounds are still being constructed, as others are already burning.{{cite journal|last=Goldner|first=Janet|title=The women of Kalabougou|journal=African Arts|date=Spring 2007|volume=40|issue=1|pages=74–79|doi=10.1162/afar.2007.40.1.74|s2cid=57567441}}
}} ====Fuel==== Kilns may be heated by burning combustible materials, such as [[wood]], [[coal]] and [[Fuel gas|gas]], or by [[electricity]]. The use of microwave energy has been investigated.Sutton, W.H. Microwave Processing of Ceramics – An Overview. MRS Online Proceedings Library 269, 3–20 (1992). The use of [[hydrogen]] as a fuel for the firing of whiteware ceramics reached a significant milestone in early 2025 with the successful deployment of large-scale pilot kilns utilising 100% hydrogen, building upon feasibility trials that began in late 2019 to decarbonize the production process.British Ceramic Confederation (2023). "Hydrogen for the ceramics sector - IFS Feasibility Report."Ceramics UK (January 2025). "Demonstrating Hydrogen in the Ceramics Sector: Phase 2 Pilot Results." Sustainable firing repurposes organic waste such as animal dung, rice chaff and more unusual fuels such as dried seaweed, olive stones and nut shells. These traditional materials provide localised energy sources, and may create unique surface effects from specific vapours.Sillar, B. (2000). Dung by Preference: The Choice of Fuel as an Example of how Andean Pottery Production is Embedded within Wider Technical, Social, and Economic Practices. Archaeometry. Modern equivalents include filtered Waste Vegetable Oil and Biodiesel, which offer cleaner-burning liquid alternatives.Sinton, C. W. (2006). Firing with Vegetable Oil. Ceramics Monthly. Similarly, compressed Biomass Pellets provide automated consistency while Biogas from anaerobic digestion replaces fossil-based methane.De Souza, J. E. A., et al. (2013). Biomass Residues as Fuel for the Ceramic Industry in the State of Alagoas: Brazil. Renewable and Sustainable Energy Reviews. Feasibility studies have demonstrated that these waste-derived fuels are technically viable for industrial whiteware production.Glass Futures (2021). Renewable waste-derived fuels for glass and ceramics manufacturing: feasibility study. GOV.UK. When used as fuels, coal and wood can introduce smoke, soot and ash into the kiln, which can affect the appearance of unprotected wares. For this reason, wares fired in wood- or coal-fired kilns are often placed in [[saggar]]s, ceramic boxes, to protect them. Modern kilns fuelled by gas or electricity are cleaner and more easily controlled than older wood- or coal-fired kilns and often allow shorter firing times. [[File:Kababougou.jpg|thumb|Pottery firing mound in [[Kalabougou]], [[Mali]]. Much of the earliest pottery would have been fired similarly.]] ====Stages==== * ''[[Biscuit (pottery)|Biscuit]]'' (or bisque)"The Fast Firing Of Biscuit Earthenware Hollow-Ware In a Single-Layer Tunnel Kiln." Salt D.L. Holmes W.H. RP737. ''Ceram Research''."New And Latest Biscuit Firing Technology". Porzellanfabriken Christian Seltmann GmbH. ''Ceram.Forum Int.''/Ber.DKG 87, No. 1/2, pp. E33–E34, E36. 2010 refers to the clay after the object is shaped to the desired form and fired in the kiln for the first time, known as "bisque fired" or "biscuit fired". This firing results in both chemical and physical changes to the minerals of the clay body. * ''Glaze fired'' is the final stage of some pottery making, or ''glost fired''. A [[Ceramic glaze|glaze]] may be applied to the biscuit ware, and the object can be decorated in several ways. After this, the object is "glazed fired", causing the glaze to melt and adhere to it. Depending on the temperature schedule, the glaze firing may also further mature the body as chemical and physical changes continue. === Decorating === Pottery may be decorated in many different ways. Some decoration can be done before or after the firing, and may be undertaken before or after glazing. ====Methods==== [[File:Pottery in China 2.jpg|thumb|Hand painting a vase.]] * Painting has been used since early prehistoric times, and can be very elaborate. The painting is often applied to pottery that has been fired once and may then be overlaid with a glaze. Many [[pigment]]s change colour when fired, and the painter must allow for this. * [[Ceramic glaze|Glaze]]: Perhaps the most common form of decoration, which also serves as protection to the pottery, by being tougher and keeping liquid from penetrating the pottery. Glaze may be colourless, especially over painting, or coloured and opaque. * Crystalline glaze: characterised by crystalline clusters of various shapes and colours embedded in a more uniform and opaque glaze, produced by the slow cooling of the glost fire. * [[Carving]]: Pottery vessels may be decorated by shallow carving of the clay body, typically with a knife or similar instrument used on the wheel. This is common in Chinese porcelain of the classic period. * [[Burnishing (pottery)|Burnishing]]: The surface of pottery wares may be ''burnished'' before firing by rubbing with a suitable instrument of wood, steel, or stone to produce a polished finish that survives firing. It is possible to produce very highly polished wares when fine clays are used or when the polishing is carried out on wares that have been partially dried and contain little water, though wares in this condition are extremely fragile and the risk of breakage is high. * [[Terra Sigillata]] is an ancient form of decorating ceramics that was first developed in Ancient Greece. * [[Lithography]], also called litho, although the alternative names of [[Transfer-print|transfer print]] or "''decal''" are also common. These are used to apply designs to articles. The litho comprises three layers: the colour, or image, layer, which contains the decorative design; the cover coat, a clear protective layer that may incorporate a low-melting glass; and the backing paper on which the design is printed by screen printing or lithography. There are various methods for transferring the design while removing the backing paper, some of which are suited to machine application. * Banding is the application by hand or by machine of a band of colour to the edge of a plate or cup. Also known as "lining", this operation is often carried out on a potter's wheel. * [[Agateware]]: named after its resemblance to the mineral [[agate]], is produced by partially blending clays of differing colours. In Japan, the term "''neriage''" is used, whilst in China, where such things have been made since at least the [[Tang dynasty]], they are called "''marbled''" wares. * [[Digital printing]]: high-resolution inkjet technology has been a recent, significant developmenthttps://www.ceramicindustry.com/articles/93433-digital-decoration-of-ceramic-tiles{{Dead link | date=June 2026 | fix-attempted=yes}} Patented in the late 1990s and commercially viable by 2005, it became the tile industry standard by 2012 before extending into ceramic tableware.{{cite journal |last1=Sanz |first1=V. |last2=Reig |first2=Y. |last3=Feliu |first3=C. |last4=Bautista |first4=Y. |last5=Ribes |first5=C. |last6=Edwards |first6=M. |year=2012 |title=Technical Evolution of Ceramic Tile Printing |journal=Journal of Imaging Science and Technology |volume=56 |issue=5 |pages=50402-1–50402-7 |doi=10.2352/j.imagingsci.technol.12.56.5.050402}}{{cite conference |last1=Hutchings |first1=I. |year=2010 |title=Ink-jet printing for the decoration of ceramic tiles: Technology and opportunities |book-title=Qualicer 2010: XI World Congress on Ceramic Tile Quality |pages=1–14 |url=https://www.qualicer.org/recopilatorio/ponencias/pdfs/2010234.pdf}}{{cite journal |last1=Gardini |first1=D. |last2=Blosi |first2=M. |last3=Dondi |first3=M. |last4=Zanelli |first4=C. |last5=Baldi |first5=G. |year=2014 |title=Ink technology for digital decoration of ceramic tiles |journal=Boletín de la Sociedad Española de Cerámica y Vidrio |volume=53 |issue=4 |pages=161–171 |doi=10.3989/cyv.2014.v53.i4}}{{cite journal |last1=Moreno |first1=R. |year=2012 |title=Inkjet printing of ceramic suspensions |journal=Advanced Engineering Materials |volume=14 |issue=12 |pages=1037–1049 |doi=10.1002/adem.201200024}} Using metal-oxide inks, printers replicate textures like marble with photorealistic precision.https://www.digitaltileprinting.com/technology{{Dead link | date=June 2026 | fix-attempted=yes}} This non-contact method decorates irregular surfaces without damaging fragile pieces.

Its purpose is often decorative, though it can also be used to mask undesirable features in the clay to which it is applied. The engobe may be applied by painting or by dipping to provide a uniform, smooth coating. Such decoration is characteristic of [[slipware]]. For [[sgraffito]] decoration, a layer of engobe is scratched through to reveal the underlying clay. * Gold: Decoration with gold is used on some high-quality ware. Different methods exist for its application, including:[[File:Sèvres - brunissage 13.jpg|thumb|Burnishing a plate's gold decoration]] ** ''Best gold'' – a suspension of gold powder in essential oils mixed with a flux and a mercury salt extended. A painting technique can apply this. From the kiln, the decoration is dull and requires burnishing to reveal the full colour ** ''Acid Gold'' – a form of gold decoration developed in the early 1860s at the English factory of [[Mintons Ltd]]. The glazed surface is etched with diluted [[hydrofluoric acid]] before application of the gold. The process demands great skill and is used for the decoration only of ware of the highest class. ** ''Bright Gold'' – consists of a solution of gold sulphoresinate together with other metal resonates and a flux. The name derives from the appearance of the decoration immediately after removal from the kiln, as it requires no burnishing ** ''Mussel Gold'' – an old method of gold decoration. It was made by rubbing together gold leaf, sugar, and salt, followed by washing to remove solubles * [[Underglaze]] decoration is applied, by several techniques, onto ware before it is glazed; an example is [[Blue and white porcelain|blue and white wares]]. Several techniques can be applied. * [[In-glaze decoration]] is applied on the surface of the [[Ceramic glaze|glaze]] before the [[glost firing]]. * [[On-glaze decoration]] is applied on top of the already fired, glazed surface, and then fixed in a second firing at a relatively low temperature. ===Glazing=== {{Main|Ceramic glaze}} [[File:Sèvres - Émaillage - insufflation 050.jpg|thumb|Spraying glaze onto a vase]] Glaze is a glassy coating on pottery, and reasons to use it include decoration, ensuring the item is impermeable to liquids, and minimizing the adherence of pollutants. Glaze may be applied by spraying, dipping, trailing, or brushing on an aqueous suspension of the unfired glaze. The colour of a glaze after firing may be significantly different from before firing. To prevent glazed wares sticking to [[kiln furniture]] during firing, either a small part of the object being fired (for example, the foot) is left unglazed or special refractory "''spurs''" are used as supports. These are removed and discarded after the firing. Some specialised glazing techniques include: * [[Salt glaze pottery|Salt-glazing]] – [[common salt]] is introduced to the kiln during the firing process. The high temperatures cause the salt to volatilise, depositing it on the surface of the ware, where it reacts with the body to form a sodium aluminosilicate glaze. In the 17th and 18th centuries, salt-glazing was used in the manufacture of domestic pottery. Now, except for use by some studio potters, the process is obsolete. The last large-scale application before its demise in the face of environmental clean air restrictions was in the production of salt-glazed [[Sanitary sewer|sewer-pipes]].{{cite journal |last1=Schurecht |first1=H.

The ash generally came from combustion waste from kiln fuelling, although the potential of ash derived from arable crop wastes has been investigated."Ash Glaze Research." C. Metcalfe. ''Ceramic Review'' No. 202. 2003. pp. 48–50. Ash glazes are of historical interest in the Far East, although there are reports of small-scale use in other locations such as the [[Catawba Valley Pottery]] in the United States. They are now limited to a small number of studio potters who value the unpredictability that arises from the raw material's variability."Glaze From Wood Ashes And Their Colour Characteristics." Y-S. Han, B-H. Lee. ''Korean Ceramic Society'' 41. No. 2. 2004. ===Health and environmental issues=== Although many of the environmental effects of pottery production have existed for millennia, some have been amplified by modern technology and production scales. The principal factors for consideration fall into two categories: * Effects on workers: Notable risks include [[silicosis]], [[toxic heavy metal|heavy metal poisoning]], poor [[indoor air quality]], [[noise health effects|dangerous sound levels]] and possible [[over-illumination]]. * Effects on the general environment. Historically, [[lead poisoning]] (''plumbism'') was a significant health concern to those glazing pottery. This was recognised at least as early as the nineteenth century. The first legislation in the UK to limit pottery workers' exposure to lead was included in the [[Factory Acts#Factories Act Extension Act 1867|Factories Act Extension Act in 1864]], with further amendments introduced in 1899.{{Cite web |url=http://www.stokemuseums.org.uk/collections/browse_collections/ceramics/research_resources/general/health_risks_pottery |title=Stoke Museums – Health Risks in a Victorian Pottery Industry |date=7 July 2012 |website= |access-date=23 February 2022 |archive-url=https://web.archive.org/web/20120707001548/http://www.stokemuseums.org.uk/collections/browse_collections/ceramics/research_resources/general/health_risks_pottery |archive-date=7 July 2012 }}{{cite web | url=https://www.historyofosh.org.uk/timeline.html | title=Timeline – History of Occupational Safety and Health }} [[Silicosis]] is an [[occupational lung disease]] caused by inhaling large amounts of crystalline silica dust, usually over many years. Workers in the ceramic industry can develop it due to exposure to [[silica]] dust in the raw materials; colloquially, it has been known as 'Potter's rot'. Less than 10 years after its introduction in 1720 as a raw material for the British ceramics industry, the negative effects of calcined flint on workers' lungs had been noted.'The Successful Prevention Of Silicosis Among China Biscuit Workers In The North Staffordshire Potteries.' A. Meiklejohn.

Therefore, much of this history can only be found among the [[Artifact (archaeology)|artifacts]] of [[archaeology]]. Because pottery is so durable, pottery and [[Sherd|shards]] of pottery survive for millennia at [[archaeological site]]s and are typically the most common and important artifacts to survive. Many prehistoric cultures are named after the pottery that is the easiest way to identify their sites, and archaeologists have developed the ability to recognise different types from the chemistry of small shards. Before pottery becomes part of a culture, several conditions must generally be met. * First, there must be usable clay available. Archaeological sites where the earliest pottery was found were near deposits of readily available clay that could be properly shaped and fired. China has large deposits of a variety of clay, which gave it an advantage in the early development of fine pottery. Many countries have large deposits of various clays. * Second, it must be possible to heat the pottery to temperatures that will achieve the transformation from raw clay to ceramic. Methods to reliably create fires hot enough to [[Pottery firing|fire pottery]] did not develop until late in the development of cultures. * Third, the potter must have time available to prepare, shape, and fire the clay into pottery. Even after control of fire was achieved, humans did not seem to develop pottery until a [[sedentism|sedentary life]] was achieved. It has been hypothesized that pottery was developed only after humans established agriculture, which led to permanent settlements. However, the [[Venus of Dolní Věstonice|oldest known pottery]] is from the Czech Republic and dates to 28,000 BC, at the height of the most recent ice age, long before the beginnings of agriculture. * Fourth, there must be a sufficient need for pottery to justify the resources required for its production.William K. Barnett and John W. Hoopes, ''The Emergence of Pottery: Technology and Innovation in Ancient Society'', Smithsonian Institution Press, 1995, p. 19 ===Early pottery=== [[File:JomonPottery.JPG|thumb|upright|An Incipient [[Jōmon]] pottery vessel reconstructed from fragments (10,000–8,000 BC), [[Tokyo National Museum]], Japan]] * Methods of forming: Hand-shaping was the earliest method used to form vessels. This included the combination of [[Pinch pot|pinching]] and [[Coiling (pottery)|coiling]]. * Firing: The earliest method for firing pottery wares was the use of bonfires [[Pit fired pottery|pit-fired pottery]]. Firing times might be short, but the peak temperatures achieved in the [[Pottery firing|fire]] could be high, perhaps in the region of {{convert|900|°C|°F}}, and were reached very quickly.Metropolitan Museum of Art {{cite web |url=http://www.metmuseum.org/toah/hd/jomo/hd_jomo.htm |title=Jomon Culture (Ca. 10,500-ca. 300 B.C.) {{pipe}} Thematic Essay {{pipe}} Heilbrunn Timeline of Art History {{pipe}} the Metropolitan Museum of Art |date=October 2002 |access-date=2011-09-15 |url-status=live |archive-url=https://web.archive.org/web/20110906082446/http://www.metmuseum.org/toah/hd/jomo/hd_jomo.htm |archive-date=2011-09-06 }} * Clay: Early potters used whatever clay was available to them in their geographic vicinity. However, the lowest-quality common red clay was adequate for low-temperature fires used to make the earliest pots. Clay [[Temper (pottery)|tempered]] with sand, grit, crushed shell, or crushed pottery was often used to make bonfire-fired ceramics because it provided an open-body texture that allowed water and the clay's volatile components to escape freely. The coarser particles in the clay also acted to restrain shrinkage during drying, thereby reducing the risk of cracking. * Form: In the main, early bonfire-fired wares were made with rounded bottoms to avoid sharp angles that might be susceptible to cracking. * Glazing: the earliest pots were not glazed. * The [[potter's wheel]] was invented in [[Europe]] in the 5th millennium BC, and revolutionised pottery production. The earliest potter's wheel dates to the middle of the 5th millennium BC from the [[Cucuteni–Trypillia culture]] in western Ukraine.{{Cite book |last=Haarmann |first=Harald |author-link=Harald Haarmann |url=https://books.google.com/books?id=FkL_DwAAQBAJ&dq=danube+river+civilization+potter%27s+wheel&pg=PA40 |title=Advancement in Ancient Civilizations: Life, Culture, Science and Thought |publisher=McFarland & Company, Inc., Publishers |year=2020 |isbn=978-1-4766-4075-4 |location=Jefferson, North Carolina |page=40 |language=en}} * Moulds were used to a limited extent as early as the 5th and 6th century BC by the [[Etruscan civilization|Etruscans]]Glenn C.

This refers to the markings made on the vessels and figures using sticks with cords during their production. Recent research has elucidated how [[Jōmon pottery]] was used by its creators.{{cite journal |title=Earliest evidence for the use of pottery |author=O.E. Craig, H. Saul, A. Lucquin, Y. Nishida, K.

Alternatively, the creation of pottery in the case of the Incipient Jōmon civilisation could be due to the intensive exploitation of freshwater and marine organisms by late glacial foragers, who started developing ceramic containers for their catch. ====East Asia==== {{main|Chinese ceramics|Japanese pottery|Korean pottery}} [[Image:Ming-Schale1.jpg|thumb|Chinese Ming dynasty [[blue-and-white porcelain]] dish with a dragon]] [[File:Grès chinois Guimet.jpg|thumb|Group of 13th-century pieces of [[Longquan celadon]]]] In Japan, the [[Jōmon period]] is known for the development of [[Jōmon pottery]], characterized by rope impressions on the surface, created by pressing rope into the clay before firing. Glazed stoneware was being created as early as the 15th century BC in China. A form of [[Chinese porcelain]] became a significant Chinese export from the Tang dynasty (AD 618–906) onwards. Korean potters adopted porcelain as early as the 14th century AD.Cooper (2010), p. 75 The ceramic industry has developed greatly since the [[Goryeo]] dynasty, and [[Goryeo ware]], a celadon with unique inlaying techniques, was produced. Later, as white porcelain became more common and celadon declined in popularity, they created distinctive ceramics such as [[Buncheong]]. Japan's white porcelain was influenced by potters kidnapped during the [[Japanese invasions of Korea (1592–1598)]], known as the Ceramic Wars, and by Japanese engineers, who introduced it during the Fall of the Ming dynasty. Typically, Korean potters who settled in Arita pass on pottery techniques. Shonzui Goradoyu-go brought back the secret of its manufacture from the Chinese kilns at Jingdezhen.Cooper (2010), p. 79 In contrast to Europe, the Chinese social elite used pottery extensively at the table, for religious purposes, and for decoration, and the standards of fine pottery were very high. From the [[Song dynasty]] (960–1279) for several centuries, the tastes of Chinese elites favoured plain-coloured and exquisitely formed pieces; during this period, porcelain was perfected in [[Ding ware]], although it was the only one of the [[Five Great Kilns]] of the Song period to use it. The traditional Chinese category of high-fired wares includes stoneware types such as [[Ru ware]], [[Longquan celadon]], and [[Guan ware]]. Painted wares such as [[Cizhou ware]] had a lower status, though they were acceptable for making [[pillow#Ancient China|pillows]]. The arrival of Chinese [[blue and white porcelain]] was probably a result of the Mongol [[Yuan dynasty]] (1271–1368) dispersing artists and artisans throughout its vast empire. Both the [[Cobalt(II) oxide|cobalt]] stains used for the blue colour, and the style of painted decoration, usually based on plant shapes, were initially borrowed from the Islamic world, which the Mongols had also conquered. At the same time, [[Jingdezhen porcelain]], produced in Imperial factories, took the undisputed leading role in production. The new, elaborately painted style was now favoured at court, and gradually more colours were added. The secret of making such porcelain was sought in the Islamic world and later in Europe when examples were imported from the East. Many attempts were made to imitate it in Italy and France. However, it was not produced outside of East Asia until 1709 in Germany.Cooper (2010), pp. 160–62 ====South Asia==== {{See also|Pottery in the Indian subcontinent}} [[File:Pottery wheel before 1910.jpg|thumb|A potter with his pottery wheel, [[British Raj]] (1910)]] Cord-Impressed style pottery belongs to the "Mesolithic" ceramic tradition that developed among Vindhya hunter-gatherers in Central India during the [[Mesolithic]] period.{{cite book |last1=D.

It can be divided into four periods, namely: the [[Hassuna]] period (7000–6500 BC), the Halaf period (6500–5500 BC), the [[Ubaid period]] (5500–4000 BC), and the Uruk period (4000–3100 BC). By about 5000 BC, pottery-making was becoming widespread across the region and spreading to neighbouring areas. Pottery making began in the 7th millennium BC. The earliest forms, found at the [[Hassuna]] site, were hand-formed from slabs into undecorated, unglazed, low-fired pots made from reddish-brown clays. Within the next millennium, wares were decorated with elaborate painted designs and natural forms, incising and burnished. [[File:Ubaid III pottery 5300-4700 BC Louvre Museum.jpg|thumb|200px|Earthenware Ubaid jar. c. 5,300–4,700 BCE.]] The invention of the [[potter's wheel]] in [[Mesopotamia]] sometime between 6,000 and 4,000 BC ([[Ubaid period]]) revolutionised pottery production. Newer kiln designs could fire wares to {{convert|1050|C|F}} to {{Convert|1200|C|F}}, enabling greater possibilities. Small groups of potters now carried out production for small cities, rather than individuals making wares for a family. The shapes and uses of ceramics and pottery expanded beyond simple vessels for storing and carrying to include specialized cooking utensils, pot stands, and rat traps.Cooper (2010), pp. 19–20 As the region developed new organizations and political forms, pottery became more elaborate and varied. Some wares were made using moulds, allowing for increased production to meet the needs of growing populations. Glazing was commonly used, and pottery was more decorated.Cooper (2010), pp. 20–24 In the [[Chalcolithic]] period in Mesopotamia, [[Halaf culture#Halaf pottery|Halafian pottery]] achieved a level of technical competence and sophistication, not seen until the later developments of [[Greek pottery]] with Corinthian and [[Attic ware]]. ====Europe==== {{Main|Minoan pottery|Pottery of ancient Greece|Ancient Roman pottery}} [[File:Altamura Painter - Red-Figure Calyx Krater - Walters 48262 - Side A.jpg|thumb|Greek [[Red-figure pottery|red-figure]] vase in the [[krater]] shape, between 470 and 460 BC, by the [[Altamura Painter]]]] Europe's oldest pottery, dating from circa 6700 BC, was found on the banks of the [[Samara (Volga)|Samara River]] in the middle [[Volga]] region of [[Russia]].D. W. Anthony. ''[[The Horse, the Wheel, and Language]]''. P. 149. These sites are known as the [[Yelshanka culture]]. The early inhabitants of Europe developed pottery in the [[Linear Pottery culture]] slightly later than the Near East, circa 5500–4500 BC. In the ancient Western Mediterranean, elaborately painted earthenware reached very high levels of artistic achievement in the Greek world; numerous survivals from tombs remain. Minoan pottery was characterized by complex painted decoration with natural themes.Cooper (2010), pp. 36–37 Classical Greek culture began to emerge around 1000 BC, featuring a variety of well-crafted pottery that now included the human form as a decorative motif. The pottery wheel was now in regular use. Although glazing was known to these potters, it was not widely used. Instead, a more porous clay slip was used for decoration. A wide [[Typology of Greek vase shapes|range of shapes]] for different uses developed early and remained essentially unchanged during Greek history.Cooper (2010), p. 42 Fine [[Etruscan pottery]] was heavily influenced by Greek pottery and often imported Greek potters and painters. [[Ancient Roman pottery]] made much less use of painting but relied on moulded decoration, enabling industrial-scale production. Much of the so-called red [[Samian ware]] of the Early [[Roman Empire]] was produced in modern Germany and France, where entrepreneurs established large potteries. Excavations at [[Augusta Raurica]], near Basel, Switzerland, have revealed a pottery production site in use from the 1st to the 4th century AD.{{cite web| url=https://www.deutsches-museum.de/en/exhibitions/materials-energy/ceramics/history/| archive-url=https://web.archive.org/web/20160707153740/http://www.deutsches-museum.de/en/exhibitions/materials-energy/ceramics/history| archive-date=2016-07-07| title=Deutsches Museum: History}} Pottery was hardly seen on the tables of elites from [[Hellenistic]] times until the [[Renaissance]], and most medieval wares were coarse and utilitarian, as the elites ate off metal vessels. Painted [[Hispano-Moresque ware]] from Spain, developing the styles of [[Al-Andalus]], became a luxury for late medieval elites, and was adapted in Italy into ''[[maiolica]]'' in the [[Italian Renaissance]]. Both of these were [[faience]] or [[tin-glazed]] earthenware, and fine faience continued to be made until around 1800 in various countries, especially France, with [[Nevers faience]] and several other centres. In the 17th century, imports of [[Chinese export porcelain]] and its [[Japanese export porcelain|Japanese equivalent]] raised the market expectations of fine pottery, and European manufacturers eventually learned to make porcelain, often in the form of [[soft-paste porcelain]]. From the 18th century onward, European porcelain and other wares from many producers became extremely popular, reducing Asian imports. ====United Kingdom==== {{Main|Wedgwood|Staffordshire figure|Royal Doulton|Mintons|Midwinter Pottery|Spode}} [[File:BLW Bone China Chocolate Cup.jpg|thumb|200px|Handpainted bone china cup. England, 1815–1820]] The city of [[Stoke-on-Trent]] is widely known as "The Potteries" because of the large number of pottery factories or, colloquially, "Pot Banks". It was one of the first industrial cities of the modern era, where, as early as 1785, 200 pottery manufacturers employed 20,000 workers.Richard Whipp, ''Patterns of Labour – Work and Social Change in the Pottery Industry'' (1990).Simeon Shaw, ''History of the Staffordshire Potteries: And the Rise and Progress of the Manufacture of Pottery and Porcelain; with References to Genuine Specimens, and Notices of Eminent Potters'' (1900). [https://archive.org/details/historystafford00shawgoog At the Internet Archive.] [[Josiah Wedgwood]] (1730–1795) was the dominant leader.Brian Dolan, ''Wedgwood: The First Tycoon'' (2004). In North Staffordshire, hundreds of companies produced all kinds of pottery, from tablewares and decorative pieces to industrial items. The main pottery types of earthenware, stoneware, and porcelain were all made in large quantities. The Staffordshire industry was a major innovator in developing new varieties of ceramic bodies, such as [[bone china]] and [[jasperware]], and in pioneering [[transfer printing]] and other glazing and decorating techniques. In general, Staffordshire was strongest in the middle and lower price ranges, though it also produced the finest and most expensive wares.Aileen Dawson, "The Growth of the Staffordshire Ceramic Industry", in Freestone, Ian, [[David Gaimster|Gaimster, David R. M.]] (eds), ''Pottery in the Making: World Ceramic Traditions'' (1997), pp 200–205 By the late 18th century, North Staffordshire was the largest producer of ceramics in the UK, despite significant hubs elsewhere. Large export markets took Staffordshire pottery around the world, especially in the 19th century.Dawson, 200–201 Production had begun to decline in the late 19th century, as other countries developed their industries, and declined notably after World War II. Employment fell from 45,000 in 1975 to 23,000 in 1991 and to 13,000 in 2002.{{cite news | url=https://www.theguardian.com/society/2002/may/29/guardiansocietysupplement | title=Gone to pot | newspaper=The Guardian | date=29 May 2002 | last1=Ridge | first1=Mian }} ====Arabic pottery==== {{Main|Islamic pottery|Persian pottery}} Early [[Islamic pottery]] followed the forms of the regions which the Arabs conquered. Eventually, however, there was cross-fertilization between the regions. This was most notable in the [[Chinese influences on Islamic pottery]]. Trade between China and the Islamic world occurred through a network of trading posts along the lengthy [[Silk Road]]. Middle Eastern nations imported stoneware and later porcelain from China. China imported the minerals for [[Cobalt blue]] from the Islamic-ruled [[Persia]] to decorate their [[blue and white porcelain]], which they then exported to the Islamic world. Likewise, Arabic art contributed to a lasting pottery form identified as [[Hispano-Moresque]] in [[Andalucia]]. Unique Islamic forms were also developed, including [[fritware]], [[lusterware]], and specialized glazes such as [[tin-glazing]], which led to the emergence of the popular [[maiolica]].Nelson (1966), pp. 23–26 One major emphasis in ceramic development in the Muslim world was the use of [[tile]] and [[Tile#Decorative tilework and coloured brick|decorative tilework]].
