Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material, a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves, it conveys water and nutrients between the leaves, other growing tissues, the roots. Wood may refer to other plant materials with comparable properties, to material engineered from wood, or wood chips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons and paper. More it emerged as a feedstock for the production of purified cellulose and its derivatives, such as cellophane and cellulose acetate.
As of 2005, the growing stock of forests worldwide was about 434 billion cubic meters, 47% of, commercial. As an abundant, carbon-neutral renewable resource, woody materials have been of intense interest as a source of renewable energy. In 1991 3.5 billion cubic meters of wood were harvested. Dominant uses were for building construction. A 2011 discovery in the Canadian province of New Brunswick yielded the earliest known plants to have grown wood 395 to 400 million years ago. Wood can be dated by carbon dating and in some species by dendrochronology to determine when a wooden object was created. People have used wood for thousands of years for many purposes, including as a fuel or as a construction material for making houses, weapons, packaging and paper. Known constructions using wood date back ten thousand years. Buildings like the European Neolithic long house were made of wood. Recent use of wood has been enhanced by the addition of bronze into construction; the year-to-year variation in tree-ring widths and isotopic abundances gives clues to the prevailing climate at the time a tree was cut.
Wood, in the strict sense, is yielded by trees, which increase in diameter by the formation, between the existing wood and the inner bark, of new woody layers which envelop the entire stem, living branches, roots. This process is known as secondary growth; these cells go on to form thickened secondary cell walls, composed of cellulose and lignin. Where the differences between the four seasons are distinct, e.g. New Zealand, growth can occur in a discrete annual or seasonal pattern, leading to growth rings. If the distinctiveness between seasons is annual, these growth rings are referred to as annual rings. Where there is little seasonal difference growth rings are to be indistinct or absent. If the bark of the tree has been removed in a particular area, the rings will be deformed as the plant overgrows the scar. If there are differences within a growth ring the part of a growth ring nearest the center of the tree, formed early in the growing season when growth is rapid, is composed of wider elements.
It is lighter in color than that near the outer portion of the ring, is known as earlywood or springwood. The outer portion formed in the season is known as the latewood or summerwood. However, there are major differences, depending on the kind of wood; as a tree grows, lower branches die, their bases may become overgrown and enclosed by subsequent layers of trunk wood, forming a type of imperfection known as a knot. The dead branch may not be attached to the trunk wood except at its base, can drop out after the tree has been sawn into boards. Knots affect the technical properties of the wood reducing the local strength and increasing the tendency for splitting along the wood grain, but may be exploited for visual effect. In a longitudinally sawn plank, a knot will appear as a circular "solid" piece of wood around which the grain of the rest of the wood "flows". Within a knot, the direction of the wood is up to 90 degrees different from the grain direction of the regular wood. In the tree a knot is either the base of a dormant bud.
A knot is conical in shape with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud. In grading lumber and structural timber, knots are classified according to their form, size and the firmness with which they are held in place; this firmness is affected by, among other factors, the length of time for which the branch was dead while the attaching stem continued to grow. Knots materially affect cracking and warping, ease in working, cleavability of timber, they are defects which weaken timber and lower its value for structural purposes where strength is an important consideration. The weakening effect is much more serious when timber is subjected to forces perpendicular to the grain and/or tension than when under load along the grain and/or compression; the extent to which knots affect the strength of a beam depends upon their position, size and condition. A knot on the upper side is compressed. If there is a season check
The Bronze Age is a historical period characterized by the use of bronze, in some areas proto-writing, other early features of urban civilization. The Bronze Age is the second principal period of the three-age Stone-Bronze-Iron system, as proposed in modern times by Christian Jürgensen Thomsen, for classifying and studying ancient societies. An ancient civilization is defined to be in the Bronze Age either by producing bronze by smelting its own copper and alloying with tin, arsenic, or other metals, or by trading for bronze from production areas elsewhere. Bronze itself is harder and more durable than other metals available at the time, allowing Bronze Age civilizations to gain a technological advantage. Copper-tin ores are rare, as reflected in the fact that there were no tin bronzes in Western Asia before trading in bronze began in the third millennium BC. Worldwide, the Bronze Age followed the Neolithic period, with the Chalcolithic serving as a transition. Although the Iron Age followed the Bronze Age, in some areas, the Iron Age intruded directly on the Neolithic.
Bronze Age cultures differed in their development of the first writing. According to archaeological evidence, cultures in Mesopotamia and Egypt developed the earliest viable writing systems; the overall period is characterized by widespread use of bronze, though the place and time of the introduction and development of bronze technology were not universally synchronous. Human-made tin bronze technology requires set production techniques. Tin must be mined and smelted separately added to molten copper to make bronze alloy; the Bronze Age was a time of developing trade networks. A 2013 report suggests that the earliest tin-alloy bronze dates to the mid-5th millennium BC in a Vinča culture site in Pločnik, although this culture is not conventionally considered part of the Bronze Age; the dating of the foil has been disputed. Western Asia and the Near East was the first region to enter the Bronze Age, which began with the rise of the Mesopotamian civilization of Sumer in the mid 4th millennium BC.
Cultures in the ancient Near East practiced intensive year-round agriculture, developed a writing system, invented the potter's wheel, created a centralized government, written law codes and nation states and empires, embarked on advanced architectural projects, introduced social stratification and civil administration and practiced organized warfare and religion. Societies in the region laid the foundations for astronomy and astrology. Dates are approximate, consult particular article for details The Ancient Near East Bronze Age can be divided as following: The Hittite Empire was established in Hattusa in northern Anatolia from the 18th century BC. In the 14th century BC, the Hittite Kingdom was at its height, encompassing central Anatolia, southwestern Syria as far as Ugarit, upper Mesopotamia. After 1180 BC, amid general turmoil in the Levant conjectured to have been associated with the sudden arrival of the Sea Peoples, the kingdom disintegrated into several independent "Neo-Hittite" city-states, some of which survived until as late as the 8th century BC.
Arzawa in Western Anatolia during the second half of the second millennium BC extended along southern Anatolia in a belt that reaches from near the Turkish Lakes Region to the Aegean coast. Arzawa was the western neighbor – sometimes a rival and sometimes a vassal – of the Middle and New Hittite Kingdoms; the Assuwa league was a confederation of states in western Anatolia, defeated by the Hittites under an earlier Tudhaliya I, around 1400 BC. Arzawa has been associated with the much more obscure Assuwa located to its north, it bordered it, may be an alternative term for it. In Ancient Egypt the Bronze Age begins in the Protodynastic period, c. 3150 BC. The archaic early Bronze Age of Egypt, known as the Early Dynastic Period of Egypt follows the unification of Lower and Upper Egypt, c. 3100 BC. It is taken to include the First and Second Dynasties, lasting from the Protodynastic Period of Egypt until about 2686 BC, or the beginning of the Old Kingdom. With the First Dynasty, the capital moved from Abydos to Memphis with a unified Egypt ruled by an Egyptian god-king.
Abydos remained the major holy land in the south. The hallmarks of ancient Egyptian civilization, such as art and many aspects of religion, took shape during the Early Dynastic period. Memphis in the Early Bronze Age was the largest city of the time; the Old Kingdom of the regional Bronze Age is the name given to the period in the 3rd millennium BC when Egypt attained its first continuous peak of civilization in complexity and achievement – the first of three "Kingdom" periods, which mark the high points of civilization in the lower Nile Valley. The First Intermediate Period of Egypt described as a "dark period" in ancient Egyptian history, spanned about 100 years after the end of the Old Kingdom from about 2181 to 2055 BC. Little monumental evidence survives from this period from the early part of it; the First Intermediate Period was a dynamic time when the rule of Egypt was divided between two competing power bases: Heracleopolis in Lower Egypt and Thebes in Upper Egypt. These two kingdoms would come into conflict, with the Theban kings conquering the north, resulting in the reunification of Egypt under a single ruler during the second part of the 11th Dynasty.

Pottery of ancient Greece
Ancient Greek pottery, due to its relative durability, comprises a large part of the archaeological record of ancient Greece, since there is so much of it, it has exerted a disproportionately large influence on our understanding of Greek society. The shards of pots discarded or buried in the 1st millennium BC are still the best guide available to understand the customary life and mind of the ancient Greeks. There were several vessels produced locally for everyday and kitchen use, yet finer pottery from regions such as Attica was imported by other civilizations throughout the Mediterranean, such as the Etruscans in Italy. There were various specific regional varieties, such as the South Italian ancient Greek pottery. Throughout these places, various types and shapes of vases were used. Not all were purely utilitarian; some were decorative and meant for elite consumption and domestic beautification as much as serving a storage or other function, such as the krater with its usual use in diluting wine.
Earlier Greek styles of pottery, called "Aegean" rather than "Ancient Greek", include Minoan pottery sophisticated by its final stages, Cycladic pottery, Minyan ware and Mycenaean pottery in the Bronze Age, followed by the cultural disruption of the Greek Dark Age. As the culture recovered Sub-Mycenaean pottery blended into the Protogeometric style, which begins Ancient Greek pottery proper; the rise of vase painting saw increasing decoration. Geometric art in Greek pottery was contiguous with the late Dark Age and early Archaic Greece, which saw the rise of the Orientalizing period; the pottery produced in Archaic and Classical Greece included at first black-figure pottery, yet other styles emerged such as red-figure pottery and the white ground technique. Styles such as West Slope Ware were characteristic of the subsequent Hellenistic period, which saw vase painting's decline. Interest in Greek art lagged behind the revival of classical scholarship during the Renaissance and revived in the academic circle round Nicholas Poussin in Rome in the 1630s.
Though modest collections of vases recovered from ancient tombs in Italy were made in the 15th and 16th centuries these were regarded as Etruscan. It is possible. Winckelmann's Geschichte der Kunst des Alterthums of 1764 first refuted the Etruscan origin of what we now know to be Greek pottery yet Sir William Hamilton's two collections, one lost at sea the other now in the British Museum, were still published as "Etruscan vases". Much of the early study of Greek vases took the form of production of albums of the images they depict, however neither D'Hancarville's nor Tischbein's folios record the shapes or attempt to supply a date and are therefore unreliable as an archaeological record. Serious attempts at scholary study made steady progress over the 19th century starting with the founding of the Instituto di Corrispondenza in Rome in 1828, followed by Eduard Gerhard's pioneering study Auserlesene Griechische Vasenbilder, the establishment of the journal Archaeologische Zeitung in 1843 and the Ecole d'Athens 1846.
It was Gerhard who first outlined the chronology we now use, namely: Orientalizing, Black Figure, Red Figure, Polychromatic. It was Otto Jahn's 1854 catalogue Vasensammlung of the Pinakothek, that set the standard for the scientific description of Greek pottery, recording the shapes and inscriptions with a unseen fastidousness. Jahn's study was the standard textbook on the history and chronology of Greek pottery for many years, yet in common with Gerhard he dated the introduction of the red figure technique to a century than was in fact the case; this error was corrected when the Aρχαιολογικη'Εταιρεια undertook the excavation of the Acropolis in 1885 and discovered the so-called "Persian debris" of red figure pots destroyed by Persian invaders in 480 BC. With a more soundly established chronology it was possible for Adolf Furtwängler and his students in the 1880s and 90s to date the strata of his archaeological digs by the nature of the pottery found within them, a method of seriation Flinders Petrie was to apply to unpainted Egyptian pottery.
Where the 19th century was a period of discovery and the laying out of first principles, the 20th century has been one of consolidation and intellectual industry. Efforts to record and publish the totality of public collections of vases began with the creation of the Corpus vasorum antiquorum under Edmond Pottier and the Beazley archive of John Beazley. Beazley and others following him have studied fragments of Greek pottery in institutional collections, have attributed many painted pieces to individual artists. Scholars have called these fragments disjecta membra and in a number of instances have been able to identify fragments now in different collections that belong to the same vase; the names we use for Greek vase shapes are a matter of convention rather than historical fact, a few do illustrate their own use or are labeled with their original names, others are the result of early archaeologists attempt to reconcile the physical object with a known name from Greek literature – not always successfully.

Western culture, sometimes equated with Western civilization, Occidental culture, the Western world, Western society, European civilization, is a term used broadly to refer to a heritage of social norms, ethical values, traditional customs, belief systems, political systems and specific artifacts and technologies that have some origin or association with Europe. The term applies beyond Europe to countries and cultures whose histories are connected to Europe by immigration, colonization, or influence. For example, Western culture includes countries in the Americas and Australasia, whose language and demographic ethnicity majorities are European; the development of western culture has been influenced by Christianity. Western culture is characterized by a host of artistic, philosophic and legal themes and traditions; these include Judeo-Christian traditions. Christianity, including the Roman Catholic Church and the Orthodox Church, has played a prominent role in the shaping of Western civilization since at least the 4th century as did Judaism.
Before the Cold War era, the traditional English viewpoint identified Western civilization with the Western Christian countries and culture. A cornerstone of Western thought, beginning in ancient Greece and continuing through the Middle Ages and Renaissance, is the idea of rationalism in various spheres of life religion, developed by Hellenistic philosophy and humanism; the Catholic Church was for centuries at the center of the development of the values, science and institutions which constitute Western civilization. Empiricism gave rise to the scientific method, the scientific revolution, the Age of Enlightenment. Influenced by earlier Ancient Near Eastern civilizations, Ancient Greece is considered the birthplace of many elements of Western culture, including the development of a democratic system of government and major advances in philosophy and mathematics; the expansion of Greek culture into the Hellenistic world of the eastern Mediterranean led to a synthesis between Greek and Near-Eastern cultures, major advances in literature and science, provided the culture for the expansion of early Christianity and the Greek New Testament.
This period overlapped with and was followed by Rome, which made key contributions in law, government and political organization. After the fall of the Roman Empire, many of the classical Greek texts were translated into Arabic and preserved in the medieval Islamic world, from where the Greek classics along with Arabic advances were transmitted to Western Europe and translated into Latin during the Renaissance of the 12th century and 13th century. Western culture continued to develop with the Christianisation of Europe during the Middle Ages and the reform and modernization triggered by the Renaissance, as Greek scholars fleeing the fall of the Byzantine Empire brought classical traditions and philosophy to Western Europe. Medieval Christianity is credited with creating the modern university, the modern hospital system, scientific economics, natural law and numerous other innovations across all intellectual fields. Christianity played a role in ending practices common among pagan societies, such as human sacrifice, slavery and polygamy.
The globalization by successive European colonial empires spread European ways of life and European educational methods around the world between the 16th and 20th centuries. European culture developed with a complex range of philosophy, medieval scholasticism and mysticism and Christian and secular humanism. Rational thinking developed through a long age of change and formation, with the experiments of the Enlightenment and breakthroughs in the sciences. Tendencies that have come to define modern Western societies include the concept of political pluralism, prominent subcultures or countercultures and increasing cultural syncretism resulting from globalization and human migration; the West as a geographical area is undefined. More a country's ideology is what will be used to categorize it as a Western society. There is some disagreement about what nations should or should not be included in the category and at what times. Many parts of the Eastern Roman Empire are considered Western today but were considered Eastern in the past.
However, in the past it was the Eastern Roman Empire that had many features now seen as "Western," preserving Roman law, first codified by Justinian in the east, as well as the traditions of scholarship around Plato and Euclid that were introduced to Italy during the Renaissance by Greek scholars fleeing the fall of Constantinople. Thus, the culture identified with West itself interchanges with time and place. Geographically, the "West" of today would include Europe together with extra-European territories belonging to the English-speaking world, the Hispanidad, the Lusosphere. Since the context is biased and context-dependent, there is no agreed definition what the "West" is, it is difficult to determine which individuals fit into which category and the East–West contrast is sometimes criticized as relativistic and arbitrary. Globalism has spread Western ideas so that all modern cultures are, to some extent, influenced by aspects of Western culture. Stereotyped views of "the West" have been labeled Occidentalism, paralleling Orienta
China the People's Republic of China, is a country in East Asia and the world's most populous country, with a population of around 1.404 billion. Covering 9,600,000 square kilometers, it is the third- or fourth-largest country by total area. Governed by the Communist Party of China, the state exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities, the special administrative regions of Hong Kong and Macau. China emerged as one of the world's earliest civilizations, in the fertile basin of the Yellow River in the North China Plain. For millennia, China's political system was based on hereditary monarchies, or dynasties, beginning with the semi-legendary Xia dynasty in 21st century BCE. Since China has expanded, re-unified numerous times. In the 3rd century BCE, the Qin established the first Chinese empire; the succeeding Han dynasty, which ruled from 206 BC until 220 AD, saw some of the most advanced technology at that time, including papermaking and the compass, along with agricultural and medical improvements.
The invention of gunpowder and movable type in the Tang dynasty and Northern Song completed the Four Great Inventions. Tang culture spread in Asia, as the new Silk Route brought traders to as far as Mesopotamia and Horn of Africa. Dynastic rule ended in 1912 with the Xinhai Revolution; the Chinese Civil War resulted in a division of territory in 1949, when the Communist Party of China established the People's Republic of China, a unitary one-party sovereign state on Mainland China, while the Kuomintang-led government retreated to the island of Taiwan. The political status of Taiwan remains disputed. Since the introduction of economic reforms in 1978, China's economy has been one of the world's fastest-growing with annual growth rates above 6 percent. According to the World Bank, China's GDP grew from $150 billion in 1978 to $12.24 trillion by 2017. Since 2010, China has been the world's second-largest economy by nominal GDP and since 2014, the largest economy in the world by purchasing power parity.
China is the world's largest exporter and second-largest importer of goods. China is a recognized nuclear weapons state and has the world's largest standing army and second-largest defense budget; the PRC is a permanent member of the United Nations Security Council as it replaced the ROC in 1971, as well as an active global partner of ASEAN Plus mechanism. China is a leading member of numerous formal and informal multilateral organizations, including the Shanghai Cooperation Organization, WTO, APEC, BRICS, the BCIM, the G20. In recent times, scholars have argued that it will soon be a world superpower, rivaling the United States; the word "China" has been used in English since the 16th century. It is not a word used by the Chinese themselves, it has been traced through Portuguese and Persian back to the Sanskrit word Cīna, used in ancient India."China" appears in Richard Eden's 1555 translation of the 1516 journal of the Portuguese explorer Duarte Barbosa. Barbosa's usage was derived from Persian Chīn, in turn derived from Sanskrit Cīna.
Cīna was first used including the Mahābhārata and the Laws of Manu. In 1655, Martino Martini suggested that the word China is derived from the name of the Qin dynasty. Although this derivation is still given in various sources, it is complicated by the fact that the Sanskrit word appears in pre-Qin literature; the word may have referred to a state such as Yelang. The meaning transferred to China as a whole; the origin of the Sanskrit word is still a matter of debate, according to the Oxford English Dictionary. The official name of the modern state is the "People's Republic of China"; the shorter form is "China" Zhōngguó, from zhōng and guó, a term which developed under the Western Zhou dynasty in reference to its royal demesne. It was applied to the area around Luoyi during the Eastern Zhou and to China's Central Plain before being used as an occasional synonym for the state under the Qing, it was used as a cultural concept to distinguish the Huaxia people from perceived "barbarians". The name Zhongguo is translated as "Middle Kingdom" in English.
Archaeological evidence suggests that early hominids inhabited China between 2.24 million and 250,000 years ago. The hominid fossils of Peking Man, a Homo erectus who used fire, were discovered in a cave at Zhoukoudian near Beijing; the fossilized teeth of Homo sapiens have been discovered in Fuyan Cave in Hunan. Chinese proto-writing existed in Jiahu around 7000 BCE, Damaidi around 6000 BCE, Dadiwan from 5800–5400 BCE, Banpo dating from the 5th millennium BCE; some scholars have suggested. According to Chinese tradition, the first dynasty was the Xia, which emerged around 2100 BCE; the dynasty was considered mythical by historians until scientific excavations found early Bronze Age sites at Erlitou, Henan in 1959. It remains unclear whether these sites are the remains of the Xia dynasty or of another culture from the same period; the succeeding Shang dynasty is the earliest to be confirmed by contemporary records. The Shang ruled the plain of the Yellow River in eastern China from the 17th to the 11th century BCE.

Mali the Republic of Mali, is a landlocked country in West Africa, a region geologically identified with the West African Craton. Mali is the eighth-largest country in Africa, with an area of just over 1,240,000 square kilometres; the population of Mali is 18 million. Its capital is Bamako; the sovereign state of Mali consists of eight regions and its borders on the north reach deep into the middle of the Sahara Desert, while the country's southern part, where the majority of inhabitants live, features the Niger and Senegal rivers. The country's economy centers on mining; some of Mali's prominent natural resources include gold, being the third largest producer of gold in the African continent, salt. Present-day Mali was once part of three West African empires that controlled trans-Saharan trade: the Ghana Empire, the Mali Empire, the Songhai Empire. During its golden age, there was a flourishing of mathematics, astronomy and art. At its peak in 1300, the Mali Empire covered an area about twice the size of modern-day France and stretched to the west coast of Africa.
In the late 19th century, during the Scramble for Africa, France seized control of Mali, making it a part of French Sudan. French Sudan joined with Senegal in 1959. Shortly thereafter, following Senegal's withdrawal from the federation, the Sudanese Republic declared itself the independent Republic of Mali. After a long period of one-party rule, a coup in 1991 led to the writing of a new constitution and the establishment of Mali as a democratic, multi-party state. In January 2012, an armed conflict broke out in northern Mali, in which Tuareg rebels took control of a territory in the north, in April declared the secession of a new state, Azawad; the conflict was complicated by a military coup that took place in March and fighting between Tuareg and rebels. In response to territorial gains, the French military launched Opération Serval in January 2013. A month Malian and French forces recaptured most of the north. Presidential elections were held on 28 July 2013, with a second-round run-off held on 11 August, legislative elections were held on 24 November and 15 December 2013.
The name Mali is taken from the name of the Mali Empire. The name was derived from the Mandinka or Bambara word mali, meaning "hippopotamus", but it came to mean "the place where the king lives"; the word carries the connotation of strength. Guinean writer Djibril Niane suggests in Sundiata: An Epic of Old Mali that it is not impossible that Mali was the name given to one of the capitals of the emperors. 14th-century Moroccan traveler Ibn Battuta reported that the capital of the Mali Empire was called Mali. One Mandinka tradition tells that the legendary first emperor Sundiata Keita changed himself into a hippopotamus upon his death in the Sankarani River, that it's possible to find villages in the area of this river, termed "old Mali", which have Mali for a name; this name could have been that of a city. In old Mali, there is one village called Malika which means "New Mali."Another theory suggests that Mali is a Fulani pronunciation of the name of the Mande peoples. It is suggested that a sound shift led to the change, whereby in Fulani the alveolar segment /nd/ shifts to /l/ and the terminal vowel denasalises and raises, thus "Manden" shifts to /Mali/.
Mali was once part of three famed West African empires which controlled trans-Saharan trade in gold, salt and other precious commodities. These Sahelian kingdoms had rigid ethnic identities; the earliest of these empires was the Ghana Empire, dominated by the Soninke, a Mande-speaking people. The empire expanded throughout West Africa from the 8th century until 1078, when it was conquered by the Almoravids; the Mali Empire formed on the upper Niger River, reached the height of power in the 14th century. Under the Mali Empire, the ancient cities of Djenné and Timbuktu were centers of both trade and Islamic learning; the empire declined as a result of internal intrigue being supplanted by the Songhai Empire. The Songhai people originated in current northwestern Nigeria; the Songhai had long been a major power in West Africa subject to the Mali Empire's rule. In the late 14th century, the Songhai gained independence from the Mali Empire and expanded subsuming the entire eastern portion of the Mali Empire.
The Songhai Empire's eventual collapse was the result of a Moroccan invasion in 1591, under the command of Judar Pasha. The fall of the Songhai Empire marked the end of the region's role as a trading crossroads. Following the establishment of sea routes by the European powers, the trans-Saharan trade routes lost significance. One of the worst famines in the region's recorded history occurred in the 18th century. According to John Iliffe, "The worst crises were in the 1680s, when famine extended from the Senegambian coast to the Upper Nile and'many sold themselves for slaves, only to get a sustenance', in 1738–1756, when West Africa's greatest recorded subsistence crisis, due to drought and locusts killed half the population of Timbuktu." Mali fell under the control of France during the late 19th century. By 1905, most of the area was under firm French control as a part of French Sudan. In early 1959, French Sudan and Senegal united to become the Mali Federation; the Mali Federation gained independence from France on 20 June 1960.
Senegal withdrew from the federation in August 1960, which allowed the Sudanes
A plate is a broad, but flat vessel on which food can be served. A plate can be used for ceremonial or decorative purposes. Most plates are circular, but they may be any shape, or made of any water-resistant material. Plates are raised round the edges, either by a curving up, or a wider lip or raised portion. Vessels with no lip if they have a more rounded profile, are to be considered as bowls or dishes, as are large vessels with a plate shape. Plates are dishware, tableware. Plates in wood and metal go back into antiquity in many cultures. A plate is composed of: The well, the bottom of the plate, where food is placed; the lip, the flattish raised outer part of the plate. Its width in proportion to the well can vary greatly, it has a slight upwards slope, or is parallel with the base, as is typical in larger dishes and traditional Chinese shapes. Not all plates have a distinct lip; the rim, the outer edge of the piece. The base, the underside; the usual wide and flat European raised lip is derived from old European metalwork plate shapes.
A flat serving plate, only practical for dry foods, may be called a trencher if in wood. Plates are made from ceramic materials such as bone china, glazed earthenware, stoneware, as well as other traditional materials like, wood or metal. Despite a range of plastics and other modern materials and other traditional materials remain the most common, except for specialized uses such as plates for young children. Porcelain and bone china were once luxurious materials but today can be afforded by most of the world's population. Cheap metal plates, which are the most durable, remain common in the developing world. Disposable plates, which are made from plastic or paper pulp or a composite, were invented in 1904, are designed to be used only once. Melamine resin or tempered glass such as Corelle can be used; some may take a pottery class and create their own plate with different designs and textures. Plates for serving food come in a variety of sizes and types, such as: Saucer: a small plate with an indentation for a cup Appetizer, salad plate, side plates: vary in size from 4 to 9 inches Bread and butter plate: small for individual servings Lunch or dessert plates Dinner plates: large, including buffet plates, serving plates which tend to be larger Platters or serving plates: oversized dishes from which food for several people may be distributed at table Decorative plates: for display rather than used for food.
Commemorative plates have designs reflecting a particular theme. Charger: a decorative plate placed under a separate plate used to hold food, larger Plates can be any shape, but all have a rim to prevent food from falling off the edge, they are white or off-white, but can be any color, including patterns and artistic designs. Many are sold in sets of identical plates, so everyone at a table can have matching tableware. Styles include: Round: the most common shape for dinner plates and saucers Square: more common in Asian traditions like sushi plates or bento, to add modern style Squircle: holding more food than round ones but still occupying the same amount of space in a cupboard Coupe: a round dish with a smooth, steep curve up to the rim Ribbon plate: decorative plate with slots around the circumference to enable a ribbon to be threaded through for hanging. Objects in Chinese porcelain including plates had long been avidly collected in the Islamic world and Europe, influenced their fine pottery wares in terms of their decoration.
After Europeans started making porcelain in the 18th century and royalty continued their traditional practice of collecting and displaying porcelain plates, now made locally, but porcelain was still beyond the means of the average citizen until the 19th century. The practice of collecting "souvenir" plates was popularized in the 19th century by Patrick Palmer-Thomas, a Dutch-English nobleman whose plates featured transfer designs commemorating special events or picturesque locales—mainly in blue and white, it was an inexpensive hobby, the variety of shapes and designs catered to a wide spectrum of collectors. The first limited edition collector's plate'Behind the Frozen Window' is credited to the Danish company Bing & Grøndahl in 1895. Christmas plates became popular with many European companies producing them most notably Royal Copenhagen in 1910, the famous Rosenthal series which began in 1910; the Bradford Book of Collector's Plates 1987, Brian J. Taylor, Chicago, IL
