The Longshan (or Lung-shan ) culture , also sometimes referred to as the Black Pottery Culture , was a late Neolithic culture in the middle and lower Yellow River valley areas of northern China from about 3000 to 1900 BC. The first archaeological find of this culture took place at the Chengziya Archaeological Site in 1928, with the first excavations in 1930 and 1931. The culture is named after the nearby modern town of Longshan ( lit. "Dragon Mountain") in Zhangqiu , Shandong . The culture was noted for its highly polished black pottery (or egg-shell pottery). The population expanded dramatically during the 3rd millennium BC, with many settlements having rammed earth walls. It decreased in most areas around 2000 BC until the central area evolved into the Bronze Age Erlitou culture . The Longshan culture has been linked to the early Sinitic (of the Sino-Tibetan languages). According to the area and cultural type, the Longshan culture can be divided into two types: Shandong Longshan and Henan Longshan. Among them, Shandong Longshan Cultural Site includes Chengziya Site; Henan Longshan Cultural Site includes Dengfeng Wangchenggang Site in Wangwan, Taosi Site and Mengzhuang Site in Hougang.
100-607: 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
200-585: A transitional Copper Age and the Bronze Age proper . He did not include the transitional period in the Bronze Age, but described it separately from the customary stone / bronze / iron system, at the Bronze Age's beginning. He did not, however, present it as a fourth age but chose to retain the tripartite system . In 1884, Gaetano Chierici , perhaps following the lead of Evans, renamed it in Italian as
300-400: 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
400-588: 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
500-675: 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
600-409: 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
700-459: 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
800-426: 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
900-416: 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
1000-581: 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
1100-577: A single source. Knowledge of the use of copper was far more widespread than the metal itself. The European Battle Axe culture used stone axes modeled on copper axes, even with moulding carved in the stone. Ötzi the Iceman , who was found in the Ötztal Alps in 1991 and whose remains have been dated to about 3300 BC, was found with a Mondsee copper axe. Examples of Chalcolithic cultures in Europe include Vila Nova de São Pedro and Los Millares on

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

Blackware , painted Koshi ware, pottery, various ornaments made of pearl and copper, various types of tools, pieces of fabric woven from Shimul cotton thread, human and various animal skeletons, burnt clay fragments have been found at the site. In March 2018, archaeologists had discovered three carts and copper artifacts including weapons dating to 1800 BC in Sanauli village of Uttar Pradesh. The artifacts belongs to Ochre Coloured Pottery culture . Andean civilizations in South America appear to have independently invented copper smelting. The term "Chalcolithic"
1500-622: Is also applied to American civilizations that already used copper and copper alloys thousands of years before Europeans immigrated. Besides cultures in the Andes and Mesoamerica, the Old Copper complex mined and fabricated copper as tools, weapons, and personal ornaments in an area centered in the upper Great Lakes region (present-day Michigan and Wisconsin ). The evidence of smelting or alloying that has been found in North America
1600-485: Is also documented at the nearby site of Tell Maghzaliyah , which seems to be dated even earlier, and completely lacks pottery. The Timna Valley contains evidence of copper mining in 7000–5000 BC. The process of transition from Neolithic to Chalcolithic in the Middle East is characterized in archaeological stone tool assemblages by a decline in high quality raw material procurement and use. This dramatic shift
1700-401: 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
1800-485: 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
1900-618: Is doubtful; a lead bracelet, found in level XII of Yarim Tepe I, dated to the 6th millennium BC; a small cone-shaped piece of lead, found in the "Burnt House" in TT6 at Arpachiyah , dated to the Halaf period or slightly later than the Yarim Tepe bracelet; and more. Copper smelting is also documented at this site at about the same time period (soon after 6000 BC). However, the use of lead seems to precede copper smelting. Early metallurgy
2000-400: 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

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

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

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
2400-638: 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
2500-481: 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

Here, analysis of six archaeological sites determined a marked downward trend in not only material quality, but also in aesthetic variation in the lithic artefacts. Fazeli & Coningham use these results as evidence of the loss of craft specialisation caused by increased use of copper tools. The Tehran Plain findings illustrate
2900-405: 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 ,

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

Artifacts from some of these sites have been dated to 6500–1000 BC, making them some of the oldest Chalcolithic sites in the world. Some archaeologists find artifactual and structural evidence of casting by Hopewellian and Mississippian peoples to be demonstrated in the archaeological record. In

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

Archaeologists have found remains of copper metallurgy in various cultures from

The term chalcolithic is a combination of two words- Chalco+Lithic, derived from the Greek words "khalkos" meaning "copper", and "líthos" meaning "stone". But "chalcolithic" could also mislead: For readers unfamiliar with the Italian language, chalcolithic seemed to suggest another -lithic age, paradoxically part of
4900-616: 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

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.

7200-696: The late 3rd millennium BC . In the Ancient Near East the Copper Age covered about the same period, beginning in the late 5th millennium BC and lasting for about a millennium before it gave rise to the Early Bronze Age . A study in the journal Antiquity from 2013 reporting the discovery of a tin bronze foil from the Pločnik archaeological site dated to c. 4,650 BC , as well as 14 other artefacts from Bulgaria and Serbia dated to before 4,000 BC, showed that early tin bronze
7300-597: The late Dawenkou culture in Shandong, should instead be assigned to the Yangshao culture, but most describe it as the early phase of the Henan Longshan. 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
7400-586: The late Middle Ages, as European kilns were less efficient, and the right type of clay less common. It remained a speciality of Germany until the Renaissance. 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
7500-698: The late fourth to the early third millennia BC. These include the copper-smelting remains and copper artifacts of the Hongshan culture (4700–2900) and copper slag at the Yuanwozhen site. This indicates that inhabitants of the Yellow River valley had already learned how to make copper artifacts by the later Yangshao period. In the region of the Aïr Mountains , Niger, independent copper smelting developed between 3000 and 2500 BC. The process
7600-467: The likes of North American Great Lakes Old Copper complex , from around 6,500 BC, through the later copper smelting cultures. The archaeological site of Belovode, on Rudnik mountain in Serbia , has the world's oldest securely dated evidence of copper smelting at high temperature, from c. 5,000 BC . The transition from Copper Age to Bronze Age in Europe occurred between the late 5th and
7700-424: The object. Much pottery is purely utilitarian, but some can also be regarded as ceramic art . An article can be decorated before or after firing. 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
7800-430: The period. Originally, the term Bronze Age meant that either copper or bronze was being used as the chief hard substance for the manufacture of tools and weapons. Ancient writers, who provided the essential cultural references for educated people during the 19th century, used the same name for both copper- and bronze-using ages. The concept of the Copper Age was put forward by Hungarian scientist Ferenc Pulszky in
7900-468: The plains surrounding this massif. 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
8000-453: 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
8100-482: 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
8200-423: 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
8300-421: The raw materials and cause it to be reduced to FeO. 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
8400-462: The region. The Wangwan III variant of the Longshan culture is located in western and central Henan province. 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
8500-745: The same material are called terracottas . 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),
8600-481: 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
8700-471: 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,
8800-467: The southeast coast in the Rizhao area, with Yaowangcheng about 35 km to the south of Liangchengzhen. Each site is surrounded by a hierarchy of economically integrated settlements, but there are relatively few settlements in the area between the two, suggesting that they were political centers of rival polities. Production of pottery, stone tools and textiles was common. There is also evidence suggesting
8900-449: The support of elite kin networks. The technology of well construction in cities improved, while some large houses included rudimentary plumbing through clay pipes. Walls of rammed earth have been found in 20 towns in Shandong, 9 in the Central Plain and one ( Taosi ) in southern Shanxi, suggesting conflict between polities in these areas. The introduction of the dagger-axe , a purely military weapon that cannot be used for hunting, indicates
9000-555: The term "Longshan culture" is restricted to the middle and lower Yellow River valley. For example, the contemporaneous culture of the lower Yangtze area is now described as the Liangzhu culture . At the same time, researchers recognized the diversity within the Yellow River valley by distinguishing regional variants in Henan, Shanxi and Shaanxi from the Shandong or "classic" Longshan. In the fourth edition of his book (1986), Chang moved from
9100-527: The underlying decoration or texture of the pottery to show through. - Often used over underglaze decorations. 4. Opaque Glaze - Completely covers the surface of the pottery, hiding any underlying texture or decoration. - Useful for creating uniform, bold colors. 5. Celadon Glaze - A translucent glaze, usually in shades of green or blue. - Originated in China and is popular in East Asian ceramics. - Accentuates carved or textured designs beneath
9200-420: The world. Modern day inhabitants of Shandong have the tallest heights of any Chinese province. The tallest Longshan individual discovered so far is a 193 cm male, aged approximately 16-18 years old, from Shaanxi . Works cited Pottery Pottery is the process and the products of forming vessels and other objects with clay and other raw materials, which are fired at high temperatures to give them
9300-457: Was foxtail millet , but traces of broomcorn millet , rice and wheat have also been found. Rice grains have been found in Shandong and southern Henan, and a small rice field has been found on the Liaodong peninsula . Specialized tools for digging, harvesting and grinding grain have been recovered. The most common source of meat was the pig. Sheep and goats were apparently domesticated in
9400-497: Was a pottery workshop in province of Balochistan , Pakistan, that dates to 4,500 years ago; 12 blades and blade fragments were excavated there. These blades are 12–18 cm (5–7 in) long, 1.2–2.0 cm (0.5–0.8 in) wide, and relatively thin. Archaeological experiments show that these blades were made with a copper indenter and functioned as a potter's tool to trim and shape unfired pottery. Petrographic analysis indicates local pottery manufacturing, but also reveals
9500-620: Was destroyed, and there are indications of violence and political upheaval. At around the same time, the new large center of Fangcheng (230 ha) was built 20 km to the southeast of Taosi, on the other side of the Chong Mountains. Sanliqiao II sites are located on both sides of the Yellow River in western Henan, southwestern Shanxi and eastern Shaanxi. There are nearly a hundred settlements belonging to this regional variant which show three level settlement hierarchy. The largest site (Xiaojiaokou, 10 km southeast of modern Sanmenxia )
9600-611: Was indeed taking place by the 4th millennium BC. Since the slag identified at Norşuntepe contains no arsenic, this means that arsenic in some form was added separately. A copper axe found at Prokuplje , Serbia contains the oldest securely dated evidence of copper-making, c. 5500 BC (7,500 years ago). The find in June ;2010 extends the known record of copper smelting by about 800 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from
9700-589: Was more common than previously thought and developed independently in Europe 1,500 years before the first tin bronze alloys in the Near East . In Britain, the Chalcolithic is a short period between about 2,500 and 2,200 BC, characterized by the first appearance of objects of copper and gold, a new ceramic culture and the immigration of Beaker culture people, heralding the end of the local late Neolithic. The multiple names result from multiple definitions of
9800-520: Was not reached until much later, in the 14th century. Porcelain was also 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 effectively outside East Asia until the 18th century. The study of pottery can help to provide an insight into past cultures. Fabric analysis (see section below), used to analyse the fabric of pottery ,
9900-639: Was on a small scale. Ceramic similarities between the Indus Valley civilisation , southern Turkmenistan , and northern Iran during 4300–3300 BC of the Chalcolithic period suggest considerable mobility and trade. The term "Chalcolithic" has also been used in the context of the South Asian Stone Age . In Bhirrana , the earliest Indus civilization site, copper bangles and arrowheads were found. The inhabitants of Mehrgarh in present-day Pakistan fashioned tools with local copper ore between 7000 and 3300 BC. The Nausharo site
10000-437: Was produced in eastern Turkey ( Malatya Province ) at two ancient sites, Norşuntepe and Değirmentepe , around 4200 BC. According to Boscher (2016), hearths or natural draft furnaces, slag , ore, and pigment had been recovered throughout these sites. This was in the context of Ubaid period architectural complexes typical of southern Mesopotamian architecture. Norşuntepe site demonstrates that some form of arsenic alloying
