    Dating techniques for pottery

    In Britain, pottery was made from the Neolithic (New Stone Age) period onwards, although some parts of the British Isles were aceramic (did not produce pottery) at various points in time. This crudeness is related to the function of the vessels, which had to withstand thermal shock when placed on a fire for cooking.Fine vessels with incised and stamped decoration were also made. C., wheelmade pottery was being imported from the Roman world and finer 'Belgic-type' vessels were being produced in East Anglia.Wedging can also help produce an even moisture content.Once a clay body has been kneaded and de-aired or wedged, it is shaped by a variety of techniques. There are several materials that are referred to as clay.It is based on the fact that amino acids (the building blocks of all proteins) exist in two mirror image forms, both of which otherwise have the same chemical structures.

    The oldest evidence of pottery manufacture has been found at an archaeological site known as Odai Yamamoto, in Japan, where fragments from a specific vessel have been dated to about 16,500-14,920 years ago.Since weather patterns tend to run in cycles of a number of years, the sequence of tree-rings in a region will also reflect the same cycling, as illustrated by the graph below.By cross-linking core samples from living and dead trees, a master sequence of annual tree-ring widths can be compiled.The following is a basic introduction to pottery in archaeology, focusing particularly on the ceramics of the medieval period.The bibliography at the end provides references to more detailed and comprehensive sources. The earliest evidence of writing anywhere in the world only goes back about 5000 years.Paleoanthropologists frequently need chronometric dating systems that can date things that are many thousands or even millions of years older.Highly decorated tableware, including fine red and whitewares, were available during the Early Roman period.Imported wares, such as fine red samian from Gaul, were popular, and wheelmade pottery was manufactured in Britain.Non-agricultural Jomon peoples of Japan were producing clay pots used for food preparation that were elaborately decorated by about 13,000 years ago.Although there is not necessarily a causal relationship between a sedentary way of life and pottery-making, the introduction of pottery generally coincides with the adoption of an agricultural lifestyle, when durable and strong vessels and containers are needed. However, during the Early Neolithic era, around 8,000 BCE, special ovens used to parch cereal grains and to bake bread were being built in the Near East, which allowed people to control fire and produce high temperatures in enclosed facilities.Due to its abundance and durability, pottery is one of the most common types of items found by archaeologists during excavations, and it has the potential of providing valuable information about the human past.Clay is abundant, cheap, and adaptable, which makes it convenient for human exploitation.A clay body can be decorated before or after firing; however, prior to some shaping processes, clay must be prepared.
