Purpose To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point. Context This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. The first lesson, Isotopes of Pennies , deals with isotopes and atomic mass. The second lesson, Radioactive Decay: A Sweet Simulation of Half-life , introduces the idea of half-life. By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope. They should also understand that the atoms of any element are alike but are different from atoms of other elements. Atoms may stick together in well-defined molecules or they could be packed together in large arrays.

A potter at work in Jaura, Madhya Pradesh , India Clay ware takes on varying physical characteristics during the making of pottery. Greenware refers to unfired objects. At sufficient moisture content, bodies at this stage are in their most plastic form they are soft and malleable, and hence can be easily deformed by handling.
Leather-hard refers to a clay body that has been dried partially.

Iron Age Art BCE Paleolithic Pottery Up until the s, most archeologists and anthropologists believed that pottery was first made during the period of Neolithic art c. However, the discoveries at Xianrendong and Yuchanyan, together with the cache of Jomon pottery discovered at Odaiyamamoto I site 14, BCE at Aomori Prefecture, Japan, prove beyond doubt that ceramic pottery was being made ten thousand years earlier, during the European era of Solutrean art 20, , BCE – a surprising development given the relative absence of Chinese cave art during this period.
Moreover, with better dating techniques being developed, it is probable that we will find even older sites from the Middle period of the Upper Paleolithic. For primitive Stone Age cooking pots, all that was needed was a supply of clay and a source of heat. Thus most Chinese pottery of the Upper Paleolithic until about 10, BCE was roughly made earthenware, fired in bonfires for a short time at temperatures up to degrees Celsius.
Vessels were made with round bottoms thus avoiding any sharp angles or rims that would be more prone to cracking. Glazes were not used, while decoration was limited to the use of coiled “ropes” and basketry. In Japan, from about 14, BCE, the “Jomon” culture was named after the decorative technique of leaving impressions on the outside of the pot, by pressing rope into the clay before firing it.
During the era of Chinese Neolithic art , however, the introduction of the potter’s wheel and better kilns, as well as the emergence of parallel technologies in smelting and metallurgy, helped to improve the range and quality of all types of ceramic ware. Decoration was limited to simple designs applied by stamping and impressing techniques. Early Neolithic cultures in China include:
Glass Beach – The Dump You’ll Want to Visit
Some historians believe that ceramics production may have started there in the Han dynasty BC. Pine wood was found in abundance around the town. The Chang River provided transport for raw material to the kilns as well as for later shipping of the finished products. In summary, the ample clay resources, fuel supply, convenient transportation and eventual imperial favors provided the necessary catalyst for potters from other places in China to join in the commercial pottery production in the town.
Other texts say that pottery was being made at Jingdezhen by A. Hutian had a great impact on other Jingdezhen kilns which began producing similar quality wares.
An ostracon (Greek: ὄστρακον ostrakon, plural ὄστρακα ostraka) is a piece of pottery, usually broken off from a vase or other earthenware vessel. In an archaeological or epigraphical context, ostraca refer to sherds or even small pieces of stone that have writing scratched into them. Usually these are considered to have been broken off before the writing was added; ancient.

25 Most Amazing Caves In The World
Stone Age Materials Wood The most basic material that the Stone Age people used was wood, as this was readily available and could be used for many different things, from making tools and weapons, to building shelters, to cooking with fire. Unfortunately wood rarely survives over time, so often archaeologists have to interpret how wood was used by studying the areas that was once occupied by wood, such as post-holes. When early man learned to control fire, cooking on open fires was eventually developed – probably by accident.
Evidence for when cooking meat started has not yet been found, however archaeologists working in places such as Swartkrans South Africa are searching for evidence to show that this was possibly 1 million BP.
Nov 14, · (Newser) – Wine has been used as a “social lubricant, mind-altering substance, and highly valued commodity” throughout the ages.
Elah Fortress at Khirbet Qeiyafa  Additionally, the lots drawn at Masada are believed to have been ostraca, and some potsherds resembling the lots have been found. In October , Israeli archaeologist, Yosef Garfinkel of the Hebrew University of Jerusalem , has discovered what he says to be the earliest known Hebrew text. This text was written on an Ostracon shard; Garfinkel believes this shard dates to the time of King David from the Old Testament, about 3, years ago.
Carbon dating of the Ostracon and analysis of the pottery have dated the inscription to be about 1, years older than the Dead Sea Scrolls. The inscription has yet to be deciphered, however, some words, such as king, slave and judge have been translated. The shard was found about 20 miles southwest of Jerusalem at the Elah Fortress in Khirbet Qeiyafa, the earliest known fortified city of the biblical period of Israel.

Situated in Ziyun County in the province of Guizhou in China, the enourmous cave opened as a school in with students and 8 teachers. Carved out of the mountain by wind, water, seismic shifts and other natural forces for thousands of years, it now houses rooms, small buildings, and recreational areas for the students. Entirely constructed and operated by volunteers, the displays are constantly changed and replaced. The national park was created to protect its over caves and grottoes, aside from the ecosystem and the limestone forest of the Annamite Range.
Pottery is the art of using ceramic material to make pottery wares, of which major types include earthenware, stoneware and place where such wares are made by a potter is also called a pottery (plural “potteries”). The definition of pottery used by the American Society for Testing and Materials (ASTM) is “all fired ceramic wares that contain clay when formed, except technical.
McGovern and his team searched the remains of two villages from the Neolithic era — or the last part of the Stone Age — about 30 miles south of the capital, Tbilisi. Clay vessels found at these Neolithic sites and others in Georgia suggest the people most likely stored their wine in large, round jars as big as liters, enough to hold about bottles. They also probably buried them underground to ferment, which is still practiced in Georgia to this day.
The team retrieved several jar shards from the sites, which they then chemically analyzed. To their surprise, eight had telltale signs of wine residue long absorbed into the pottery, including tartaric acid, which is like a flashing neon light indicating traces of grape, as well as malic, succinic and citric acids. McGovern said that to his knowledge, the combination of these four acids is found only in grape wine. Radiocarbon dating of the site dated jar shards to the years 6, to 5, B.
The team also found traces of ancient grape pollen, starch from grape wine and remains from Neolithic fruit flies.

China Nowhere in the world has pottery assumed such importance as in China, and the influence of Chinese porcelain on later European pottery has been profound. It is difficult to give much practical assistance on the question of Chinese marks. Most of the Chinese marks give the name of the dynasty and that of the emperor; however, many of them have been used so inconsequentially that, unless the period can also be assigned with reasonable certainty by other means, it is better to disregard them.
The dating of Chinese pottery is further complicated by the fact that there were traditional and persisting types that overlapped; quite often, therefore, dynastic labels cannot be regarded as anything more than an indication of the affinities of the particular object under discussion. Longevity is symbolized by such things as the stork, the pine, and the tortoise, the lingzhi fungus, and the bamboo, all reputed to enjoy long life.
The character shou, which also denotes longevity, is used in a variety of ornamental forms. Together, the peach and the bat represent fu and shou, happiness and long life. The bagua , consisting of eight sets of three lines, broken and unbroken in different combinations, represent natural forces. They are often seen in conjunction with the yin-yang symbol, which represents the female-male principle, and which has been well described by the pottery scholar R.
22 Chinese Inventions That Changed the World
For the better part of fifteen hundred years, the Chinese civilization has given birth to developments in navigation, spiritual balance, mathematics and natural prevention and diagnosis. Since it was this culture that was responsible for the invention and the discovery of such things as porcelain, paper, fishing reels, church bells, rudders, solar wind, the circulation of blood in the human body, the suspension bridge, the technique for drilling for natural gas, the iron plough, the seed drill, the mechanical clock, the seismograph, planting and hoeing techniques and the compass.

Production stages[ edit ] Clay ware takes on varying physical characteristics during the making of pottery. Greenware refers to unfired objects. At sufficient moisture content, bodies at this stage are in their most plastic form they are soft and malleable, and hence can be easily deformed by handling. Leather-hard refers to a clay body that has been dried partially.
Clay bodies at this stage are very firm and only slightly pliable. Trimming and handle attachment often occurs at the leather-hard state. At that moisture level, the item is ready to be bisque fired. Biscuit or bisque   refers to the clay after the object is shaped to the desired form and fired in the kiln for the first time, known as “bisque fired” or “biscuit fired”.
This firing changes the clay body in several ways. Mineral components of the clay body will undergo chemical changes that will change the colour of the clay. Glaze fired is the final stage of some pottery making. A glaze may be applied to the bisque form and the object can be decorated in several ways. After this the object is “glazed fired”, which causes the glaze material to melt, then adhere to the object.

Travelling in large dug-out canoes, they came in successive waves of migration up through the islands, with the smaller islands such as Bequia being the last to be occupied on any meaningful or permanent basis. Much evidence of pre-historic life has already been unearthed on Bequia, with doubtless still more to be discovered.
A small display of pottery shards and other artefacts can be seen in the Bequia Tourism Office and at the Frangipani Hotel, providing an intriguing glimpse into Bequia’s distant past. The Bequia Heritage Foundation is also planning to include a significant Amerindian exhibit in their new building at St.
