84-589: A distinctive feature of the Longshan culture was the high level of skill in pottery making , including the use of pottery wheels , producing thin-walled and polished black pottery. This pottery was widespread in North China, and also found in the Yangtze River valley and as far as the southeastern coast. Until the 1950s, such black pottery was considered the principal diagnostic, and all of these sites were assigned to

168-400: A differentiated culture which was earlier thought to be typical Indus Valley civilisation (IVC) culture. Pottery is durable, and fragments, at least, often survive long after artifacts made from less-durable materials have decayed past recognition. Combined with other evidence, the study of pottery artefacts is helpful in the development of theories on the organisation, economic condition and

252-571: A form of divination . Evidence of human sacrifice becomes more common in Shaanxi and the Central Plain in the late Longshan period. Excavations in the 1950s in Shanxian , western Henan, identified a Miaodigou II phase (3000 to 2600 BC) transitional between the preceding Yangshao culture and the later Henan Longshan. A minority of archaeologists have suggested that this phase, which is contemporaneous with

336-640: A given point on the Chongfen Mountain to the East. In ancient times, sunrises related to the winter and summer solstices might have been visible through different slots. This means these slots might share a function similar to the Thirteen Towers of the Chankillo Observatory , having been intentionally constructed for calendrical observation of the sunrise on particular given days, in order to follow

420-667: A hard and durable form. The place where such wares are made by a potter is also called a pottery (plural potteries ). The definition of pottery , used by the ASTM International , is "all fired ceramic wares that contain clay when formed, except technical, structural, and refractory products". End applications include tableware , decorative ware , sanitary ware , and in technology and industry such as electrical insulators and laboratory ware. In art history and archaeology , especially of ancient and prehistoric periods, pottery often means only vessels, and sculpted figurines of

504-409: A heightened prevalence of warfare. This period also saw increasingly widespread and skilled manufacturing of copper tools, rings and bells, alongside a few bronze and brass objects, paving the way for the emergence of the later Bronze Age cultures. The center of Shandong is a mountainous area, including Mount Tai (1,545 m) and other several other peaks over 1000 m. Longshan settlements are found on

588-463: A large cache of grave goods (some with over 200 objects, including jades, copper bells, wooden and crocodile skin musical instruments); middle-size graves featured painted wooden coffins and luxury objects; most of the small graves did not have grave goods. Musical instruments have been unearthed at Taosi, including drums, chimes, and a jaw harp . A single bronze bell was also found at a Taosi grave. Several Chinese archaeologists postulate that Taosi

672-459: A locality. The main ingredient of the body is clay . Some different types used for pottery include: It is common for clays and other raw materials to be mixed to produce clay bodies suited to specific purposes. Various mineral processing techniques are often utilised before mixing the raw materials, with comminution being effectively universal for non-clay materials. Examples of non-clay materials include: The production of pottery includes

756-426: A model centered on the Central Plain to a model of distinctive regional cultures whose development was stimulated by interaction between regions, a situation he called the "Chinese interaction sphere". Also in the 1980s, Yan Wenming proposed the term "Longshan era" to encompass cultures of the late Neolithic (3rd millennium BC) across the area, though he assigned the Central Plain a leading role. The most important crop

840-416: A more distant connection between groups, such as trade in the same market or even relatively close settlements. Techniques that require more studied replication (i.e., the selection of clay and the fashioning of clay) may indicate a closer connection between peoples, as these methods are usually only transmissible between potters and those otherwise directly involved in production. Such a relationship requires

924-581: A rough guide, modern earthenwares are normally fired at temperatures in the range of about 1,000  °C (1,830 °F) to 1,200 °C (2,190 °F); stonewares at between about 1,100 °C (2,010 °F) to 1,300 °C (2,370 °F); and porcelains at between about 1,200 °C (2,190 °F) to 1,400 °C (2,550 °F). Historically, reaching high temperatures was a long-lasting challenge, and earthenware can be fired effectively as low as 600 °C (1,112 °F), achievable in primitive pit firing . The time spent at any particular temperature

Glossy Glaze - Produces a shiny, reflective surface. - Highlights intricate patterns and textures. - Often used for decorative purposes. 2. Matte Glaze - Provides a smooth, non-reflective finish. - Suitable for modern and minimalist designs. - Ideal for functional wares like plates and mugs, as it minimizes glare. 3. Transparent Glaze - Can be glossy or matte. - Allows

1092-471: Is 240 ha in area, whereas local centers range from 30 ha to 70 ha. Dwelling types of Sanliqiao II culture include both aboveground and semi-subterranean type houses as well as homes horizontally dug into loess cliffs with walls frequently coated with plaster. There is noted similarity between the ceramics of this variant and that of the Kexingzhuang II variant. Kexingzhuang II sites are scattered across

1176-401: Is also important, the combination of heat and time is known as heatwork . Kilns can be monitored by pyrometers , thermocouples and pyrometric devices . The atmosphere within a kiln during firing can affect the appearance of the body and glaze. Key to this is the differing colours of the various oxides of iron, such as iron(III) oxide (also known as ferric oxide or Fe 2 O 3 ) which

1260-482: Is associated with brown-red colours, whilst iron(II) oxide (also known as ferrous oxide or FeO) is associated with much darker colours, including black. The oxygen concentration in the kiln influences the type, and relative proportions, of these iron oxides in fired the body and glaze: for example, where there is a lack of oxygen during firing the associated carbon monoxide (CO) will readily react with oxygen in Fe 2 O 3 in

1344-400: Is important part of archaeology for understanding the archaeological culture of the excavated site by studying the fabric of artifacts, such as their usage, source material composition, decorative pattern, color of patterns, etc. This helps to understand characteristics, sophistication , habits, technology, tools, trade, etc. of the people who made and used the pottery. Carbon dating reveals

1428-426: 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. 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. Glaze is a glassy coating on pottery, and reasons to use it include decoration, ensuring

1512-476: Is located in northern Henan and Southern Hebei. The sites of this Longshan subtradition are densely distributed along the rivers in this region, many of the sites being less than 1 km apart. Walled sites include Hougang (10 ha) and Mengzhuang (16 ha). The Hougang II variant is known for having the first wells in the Yellow River area and the method they employed continued to be used by early bronze-age states in

1596-425: Is made by heating materials, generally including kaolin , in a kiln to temperatures between 1,200 and 1,400 °C (2,200 and 2,600 °F). This is higher than used for the other types, and achieving these temperatures was a long struggle, as well as realizing what materials were needed. The toughness, strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and

1680-633: Is normally fired below 1200 °C. Because unglazed earthenware is porous, it has limited utility for the storage of liquids or as tableware. However, earthenware has had 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 , especially when unglazed or used for sculpture. The development of ceramic glaze made impermeable pottery possible, improving

1764-481: Is not always the case; for example fritware uses no or little clay, so falls outside these groups. Historic pottery of all these types is often grouped as either "fine" wares, relatively expensive and well-made, and following the aesthetic taste of the culture concerned, or alternatively "coarse", "popular", "folk" or "village" wares, mostly undecorated, or simply so, and often less well-made. Cooking in pottery became less popular once metal pots became available, but

1848-430: Is placed within the context of linguistic and migratory patterns, it becomes an even more prevalent category of social artifact. As proposed by Olivier P. Gosselain, it is possible to understand ranges of cross-cultural interaction by looking closely at the chaîne opératoire of ceramic production. The methods used to produce pottery in early Sub-Saharan Africa are divisible into three categories: techniques visible to

1932-405: Is shaped by a variety of techniques, which include: Prior to firing, the water in an article needs to be removed. A number of different stages, or conditions of the article, can be identified: Firing produces permanent and irreversible chemical and physical changes in the body. It is only after firing that the article or material is pottery. In lower-fired pottery, the changes include sintering ,

2016-455: Is still used for dishes that benefit from the qualities of pottery cooking, typically slow cooking in an oven, such as biryani , cassoulet , daube , tagine , jollof rice , kedjenou , cazuela and types of baked beans . The earliest forms of pottery were made from clays that were fired at low temperatures, initially in pit-fires or in open bonfires . They were hand formed and undecorated. Earthenware can be fired as low as 600 °C, and

2100-400: The "clay matrix" – composed of grains of less than 0.02 mm grains which can be seen using the high-powered microscopes or a scanning electron microscope , and the "clay inclusions" – which are larger grains of clay and could be seen with the naked eye or a low-power binocular microscope. For geologists, fabric analysis means spatial arrangement of minerals in a rock. For Archaeologists,

2184-566: The "fabric analysis" of pottery entails the study of clay matrix and inclusions in the clay body as well as the firing temperature and conditions . Analysis is done to examine the following 3 in detail: The Six fabrics of Kalibangan is a good example of fabric analysis. Body , or clay body, is the material used to form pottery. Thus a potter might prepare, or order from a supplier, such an amount of earthenware body, stoneware body or porcelain body. The compositions of clay bodies varies considerably, and include both prepared and 'as dug';

2268-523: The Erlitou culture ; specifically a 70 ha walled center at Xinzhai is said to lead "typologically directly to early Erlitou". At 300 ha in area, the walled site at Taosi in the Linfen Basin in southern Shanxi , is the largest Longshan settlement in the middle Yellow River area. Mortuary practices indicate a complex society with at least three social ranks. In the late Taosi period, the rammed-earth wall

As the Neolithic population in China reached its peak, hierarchies of settlements developed. In physically circumscribed locations, such as the basin of the Fen River in southern Shanxi, the Yellow River in western Henan (confined by

Dogs were also eaten, particularly in Shandong, though cattle were less important. Small-scale production of silk by raising and domesticating the silkworm in early sericulture was also known. Remains have been found in Shaanxi and southern Henan of scapulae of cattle, pigs, sheep and deer that were heated as

2520-526: The Russian Far East (14,000 BC), Sub-Saharan Africa (9,400 BC), South America (9,000s–7,000s BC), and the Middle East (7,000s–6,000s BC). Pottery is made by forming a clay body into objects of a desired shape and heating them to high temperatures (600–1600 °C) in a bonfire , pit or kiln , which induces reactions that lead to permanent changes including increasing the strength and rigidity of

2604-508: The Wei River valley in southern Shaanxi . The largest site in this area is 60 ha, which is less than half the size of the largest Yangshao -era site in this region. A population decline is also noted during this period, which scholars attribute to migration caused by environmental changes. Out of 718 identified sites, 25 would be considered "medium sized" centers surrounded by small village settlements in three-level settlement hierarchy. Towards

2688-624: The Yi and Luo rivers of central Henan, culminating in the Erlitou culture . The material culture in this area shows a continuous development, through a Xinzhai phase centred on the Song Mountains immediately to the south. In the Taosi area, however, there is no such continuity between Longshan and Erlitou material culture, suggesting a collapse in that area and later expansion from the Erlitou core area. During

2772-552: The Zhongtiao Mountains and Xiao Mountains ) and the coastal Rizhao plain of southeast Shandong, a few very large (over 200 ha) centers developed. In more open areas, such as the rest of Shandong, the Central Plain (in Henan) and the Wei River basin in Shaanxi, local centers were more numerous, smaller (generally 20 to 60 ha) and fairly evenly spaced. Cities were linked to large networks of surrounding towns and villages, indicating

All lunar months always have an integer-dependent number of days, since the half-days of lunar months do not exist in practice. The 29 open spaces might match the 29 days of some lunar months. Most lunar months have 30 days, and thus the 29 day lunar months would have been exceptional, requiring special treatment. One could therefore link this to

2940-441: The 19th and early 20th centuries, there were opposing views on the origin of Chinese culture and civilization: Western origin versus native origin. One of the most representative of "Western Origin" for the culture of prehistoric China was put forward by J. G. Andersson (1874–1960), who excavated the Neolithic site of Yangshao , Henan, in 1921. Many of the unearthed ceramics from Yangshao were painted potsherds. Andersson believed that

3024-605: The Longshan culture. In the first edition of his influential survey The Archaeology of Ancient China , published in 1963, Kwang-chih Chang described the whole area as a "Longshanoid horizon", suggesting a fairly uniform culture attributed to expansion from a core area in the Central Plain . More recent discoveries have uncovered much more regional diversity than previously thought, so that many local cultures included within Chang's Longshanoid horizon are now viewed as distinct cultures, and

The structure consists of an outer semi-ring-shaped path, and a semi-circular rammed-earth platform with a diameter of about 60 m. The platform is 42m in diameter and over 1000 sq m in area, and can be reconstructed as a three-level altar. The most important construction preserved was a semi-cirular structure of rammed earth, facing East. Depending on

An astronomical observatory was also partially preserved at Taosi, the oldest in East Asia. This was discovered in 2003-2004. Archaeologists unearthed a Middle Taosi period semi-circular foundation just beside the southern wall of

3276-602: The Yangshao painted pottery originated from the west, with connections with Anau in Central Asia and Trypillia in Eastern Europe. Heavily flawed, this view has been long abandoned in academia. The Longshan culture period is an important period in history. The use of bronze ware, the emergence of a large number of city sites, and the wide application of thin-bodied black pottery and quick-wheel pottery-making techniques indicate that

3360-503: The ability of the involved parties to communicate effectively, implying pre-existing norms of contact or a shared language between the two. Thus, the patterns of technical diffusion in pot-making that are visible via archaeological findings also reveal patterns in societal interaction. Chronologies based on pottery are often essential for dating non-literate cultures and are often of help in the dating of historic cultures as well. Trace-element analysis , mostly by neutron activation , allows

3444-440: The ability of urban elites to exert control over the countryside and its agrarian wealth. Settlements developed into cities with clearly demarcated sections for different classes and occupations, as well as large elite residences and ritual structures. Signs of considerable population growth and rising social stratification indicate that the Longshan culture began forming into competing chieftainships, ruled by dynastic lineages with

Sites with similar pottery characteristics have the same culture, those sites which have distinct cultural characteristics but with some overlap are indicative of cultural exchange such as trade or living in vicinity or continuity of habitation, etc. Examples are black and red ware , redware , Sothi-Siswal culture and Painted Grey Ware culture . The six fabrics of Kalibangan is a good example of use of fabric analysis in identifying

Relative to other Longshan-era cultures, the gap between rich and poor in the Shandong Longshan was far less pronounced and there seemed to be less violence compared to other Longshan sites. The Shandong Longshan developed out of the Dawenkou culture and was succeeded by the Bronze Age Yueshi culture . The Hougang II variant of Longshan culture

Although the mound contains the pots of many women, who are related through their husbands' extended families, each women is responsible for her own or her immediate family's pots within the mound. 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

The ancient Chinese used shadow measurements for creating calendars that are mentioned in several ancient texts. According to the collection of Zhou Chinese poetic anthologies Classic of Poetry , one of the distant ancestors of King Wen of the Zhou dynasty used to measure gnomon shadow lengths to determine orientation around

3948-431: The cultural development of the societies that produced or acquired pottery. The study of pottery may also allow inferences to be drawn about a culture's daily life, religion, social relationships, attitudes towards neighbours, attitudes to their own world and even the way the culture understood the universe. It is valuable to look into pottery as an archaeological record of potential interaction between peoples. When pottery

4032-480: The duration of firing influences the final characteristics of the ceramic. Thus, the maximum temperature within a kiln is often held constant for a period of time to soak the wares to produce the maturity required in the body of the wares. Kilns may be heated by burning combustible materials, such as wood , coal and gas , or by electricity . The use of microwave energy has been investigated. When used as fuels, coal and wood can introduce smoke, soot and ash into

4116-478: The end of the 3rd millennium BC, the population decreased sharply in most of the region and many of the larger centres were abandoned, possibly due to environmental change linked to the end of the Holocene Climatic Optimum . This was matched by the disappearance of high-quality black pottery found in ritual burials. In contrast, there was a rapid growth of population and social complexity in the basin of

4200-544: The era of maximum marine transgression. The late period (2600 to 2000 BC) of the Longshan culture in the middle Yellow River area is contemporaneous with the classic Shandong Longshan culture. Most scholars regard the Chalcolithic to have begun during the Longshan culture from 2600 to 2000 BC. Several regional variants of the late middle Yellow River Longshan have been identified, including Wangwan III in western Henan, Hougang II in northern Henan and southern Hebei, Taosi in

These three categories can be used to consider the implications of the reoccurrence of a particular sort of pottery in different areas. Generally, the techniques that are easily visible (the first category of those mentioned above) are thus readily imitated, and may indicate

4368-430: The following stages: Before being shaped, clay must be prepared. This may include kneading to ensure an even moisture content throughout the body. Air trapped within the clay body needs to be removed, or de-aired, and can be accomplished either by a machine called a vacuum pug or manually by wedging . Wedging can also help produce an even moisture content. Once a clay body has been kneaded and de-aired or wedged, it

4452-481: The foot) is left unglazed or, alternatively, special refractory " spurs " are used as supports. These are removed and discarded after the firing. Some specialised glazing techniques include: Types of Glazing in Pottery. Glazing in pottery is the process of applying a coating or layer of material to ceramics that, when fired, forms a vitreous or glass-like surface. Glazes enhance the aesthetic appeal of pottery, provide

4536-646: 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 when it was first made. A degree of translucency and whiteness was achieved by the Tang dynasty (AD 618–906), and considerable quantities were being exported. The modern level of whiteness

4620-443: The former being by far the dominant type for studio and industry. The properties also vary considerably, and include plasticity and mechanical strength before firing; the firing temperature needed to mature them; properties after firing, such as permeability, mechanical strength and colour. There can be regional variations in the properties of raw materials used for pottery, and these can lead to wares that are unique in character to

4704-412: The fusing together of coarser particles in the body at their points of contact with each other. In the case of porcelain, where higher firing-temperatures are used, the physical, chemical and mineralogical properties of the constituents in the body are greatly altered. In all cases, the reason for firing is to permanently harden the wares, and the firing regime must be appropriate to the materials used. As

4788-555: The glaze. Taosi Taosi ( Chinese : 陶寺 ; pinyin : Táosì ) is an archaeological site in Xiangfen County , Shanxi , China . Taosi is considered to be part of the late phase of the Longshan culture in southern Shanxi, also known as the Taosi phase (2300 BC to 1900 BC). Taosi was surrounded by a gigantic rammed-clay enclosure. This was discovered from 1999 to 2001 by

4872-431: The interpretation, this was (a) a tall wall pierced with a number of irregularly spaced and separated slots, or (b) a series of pillars, separated by small somewhat irregular vertical spaces. This wall or line of pillars was linked to a central position from which observations could be made by peering through the empty spaces. Standing in the center of the altar and looking out, one finds that most of slots are oriented toward

4956-417: 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 it has been fired 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,

For this reason, wares fired in wood- or coal-fired kilns are often placed in the kiln in saggars , 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 to be used. Niche techniques include: [...] pots are positioned on and amid

Some scholars argue that the late Dawenkou culture should be considered the early phase of the Shandong Longshan culture. Miaodigou II sites are found in central and western Henan, southern Shanxi and the Wei River valley in Shaanxi. The tools and pottery found at these sites were significantly improved from those of

Stoneware is very tough and practical, and much of it has always been utilitarian, for the kitchen or storage rather than the table. But "fine" stoneware has been important in China , Japan and the West, and continues to be made. Many utilitarian types have also come to be appreciated as art. Porcelain

A painted pole discovered in a tomb at the prehistoric site dating from perhaps 2000 or 2300 BCE is the probably the oldest gnomon known in China. From ancient texts, we know that the gnomon was widely used in ancient China from the second century BC onward in order determine

Pottery is traditionally divided into three types: earthenware , stoneware and porcelain . All three may be glazed and unglazed. All may also be decorated by various techniques. In many examples the group a piece belongs to is immediately visually apparent, but this

The cemetery contained over 1,500 burials. The burials at Taosi were highly stratified (the most stratified of Longshan sites), with burial wealth concentrated in the graves of a few males (nine large graves). The largest graves were placed in separated rooms with murals, had

The settlement represents the most politically organized system on the Central Plains at the time. The polities in the Taosi site are considered an advanced chiefdom, but may not have developed into a higher political organization. It was not

To the north are four evenly spaced walled centers, Chengziya , Dinggong, Tianwang and Bianxianwang (from west to east), with the largest, Chengziya, enclosing only 20 ha. A pottery sherd inscribed with 11 symbols was found at Dinggong, but scholars disagree on whether it should be dated to the Neolithic period. The largest sites yet found in Shandong are Liangchengzhen (273 ha) and Yaowangcheng (368 ha). Both sites are near

5712-502: The popularity and practicality of pottery vessels. Decoration has evolved and developed through history. Stoneware is pottery that has been fired in a kiln at a relatively high temperature, from about 1,100 °C to 1,200 °C, and is stronger and non-porous to liquids. The Chinese, who developed stoneware very early on, classify this together with porcelain as high-fired wares. In contrast, stoneware could only be produced in Europe from

5796-482: The preceding Yangshao culture. Agriculture was intensified, and the consumption of domesticated animals (pigs, dogs, sheep and cattle) greatly increased. Similarities in ceramic styles of central Henan Miaodigou II with the late Dawenkou culture to the east and the late Qujialing culture to the south suggest trade contacts between the regions. There were also expansions from middle and late Dawenkou sites (3500-2600 BC) toward central Henan and northern Anhui which coincides

5880-423: The production of fermented beverages and prestige items made from jade and metal. Since both jade prestige items and utilitarian goods such as stone tools and pottery have been found at the sites, this suggests that they were also regional centers for production and exchange of goods. At Liangchengzhen, rice, foxtail millet, broomcorn millet and wheat were grown. Foxtail millet was the most important crop in terms of

An oxygen deficient condition, called a reducing atmosphere, is generated by preventing the complete combustion of the kiln fuel; this is achieved by deliberately restricting the supply of air or by supplying an excess of fuel. Firing pottery can be done using a variety of methods, with a kiln being the usual firing method. Both the maximum temperature and

The number of sites in this region triples from the Yangshao period, developing into multi-centered competitive systems. There is evidence of metallurgy at the Wangchenggang site, though it is possibly attributed to later layers. The Wangwan III variant is said to have given rise to

Pottery is one of the oldest human inventions , originating before the Neolithic period , with ceramic objects such as the Gravettian culture Venus of Dolní Věstonice figurine discovered in the Czech Republic dating back to 29,000–25,000 BC. However, the earliest known pottery vessels were discovered in Jiangxi , China, which date back to 18,000 BC. Other early Neolithic and pre-Neolithic pottery artifacts have been found, in Jōmon Japan (10,500 BC),

6216-481: The social productive forces achieved unprecedented development during this period, which led to the polarization of the rich and the poor within the society; thus the emergence of class antagonisms. The Longshan culture had individuals of extraordinary stature who have been dubbed the "Longshan giants". Some samples of Longshan culture males recovered from Shandong fell between the 180 cm to 190 cm height range, making them taller than any other Neolithic population in

6300-467: The sources of clay to be accurately identified and the thermoluminescence test can be used to provide an estimate of the date of last firing. Examining sherds from prehistory, scientists learned that during high-temperature firing, iron materials in clay record the state of the Earth's magnetic field at that moment. The "clay body" is also called the "paste" or the "fabric" , which consists of 2 things,
