Pottery is the first synthetic material ever created by humans. The term refers to objects made of clay that have been fashioned into the desired shape, dried, and either fired or baked to fix their form. 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.

Early Development of Pottery

Clay is abundant, cheap, and adaptable, which makes it convenient for human exploitation. Because usable clay is widely available, pottery was independently invented in many parts of the world at different times. The earliest recorded evidence of clay usage dates back to the Late Palaeolithic period in central and western Europe, where fired and unfired clay figurines were created as a form of artistic expression. As early as 30,000 years ago, we can also see evidence of some experimentation with clay: at a site known as Dolni Vestonice (Czech Republic), figurines made of clay mixed with crushed mammoth bone were found.

The introduction of pottery generally coincides with the adoption of an agricultural lifestyle, when durable & strong vessels & containers are needed.

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. Non-agricultural peoples of Jomon Period 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. Initially, pottery was made in open fires. 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. The use of ovens added new possibilities to the development of pottery. Around the same time, some areas of South America were also developing pottery technology.

Technical Sophistication in Pottery Production

Open firing techniques were used to produce the earliest pottery. Through this method, temperatures could range from about 600 to about 800-900 degrees Celsius, which are relatively low temperatures. Japanese Jomon pottery (dated back to 13,000 years ago) and Middle Nile Egyptian vessels (from about 10,000 years ago) are some examples of pottery produced using this technique.

Firing pottery in a kiln is another method of pottery production. Enclosing the pottery inside a chamber results in key advantages: the temperatures that can be achieved are higher, last longer, and the heat can be controlled more efficiently. The simplest forms of kilns are pit kilns, which is a pit fire installation where the fuel is placed at the bottom, followed by the pottery, and more fuel in the upper layer. Another type of kiln is an updraft kiln, which is usually a cylindrical construction divided into two compartments: the lower compartment is where the fuel is placed, while the pottery is placed in the upper compartment. This allows the heat to rise and the pottery is fired at a temperature level normally ranging from 1,000 to 1,200 degrees Celsius.

In ancient China, firing techniques allowed temperatures of about 1300-1400 degrees Celsius and even higher in some cases. At these temperatures, the mineral components of clay melt, resulting in a thin, translucent, white vitrified type of ceramic that is known as porcelain. Not all types of clay can stand temperatures this high - only some special types of clay which are largely free of impurities.

In some cases, the overall color of the pottery can be changed from its natural reddish to gray without the need of pigments, merely by manipulating the temperature and air influx in the kiln during the firing process. This type of knowledge is usually the last step in a long sequence of experimentation, an indication that pottery production in that specific society was not new, and it probably had been developing for several thousand years.

Dating Pottery & Archaeological Sites

According to the context in which the pottery was found, there are several techniques that can be applied for dating pottery. Pottery can be dated based on a stratigraphic sequence: this means that during an excavation, archaeologists study the different layers of soil and analyse how the different objects found in them relate to one another. If the layers are undisturbed, then objects found in the lower layers are older than those located in the upper layers. Some of these objects can be dated independently: radiocarbon dating can be applied to human and animal remains and even to charcoal. Pottery fragments may be found, for example, on the same layer where a piece of charcoal is found, and the radiocarbon dates obtained for the charcoal can be extended to the pottery fragments, which provide us with an approximate date for the pottery.

If the pottery fragments found belong to a well-known pottery type (e.g. Chinese or Greek pottery, which have been widely studied), then dating can be based on what is known as a typological sequence. There are well-established pottery typological systems for most regions of the world: changes in the surface decoration styles and in the shape of the vessels are normally gradual, so when a pottery fragment can be related to a well-known pottery typology, it provides a basis to assign a date to the piece.

Another method than can be applied to date pottery is called thermoluminiscence. This dating method can applied to pottery and other ceramic materials that have been fired and buried in the ground. Thermoluminiscence is often used when no other method is available, mainly because there are restrictions to its application, and its precision is rarely better than +/- 10% of the age of the sample.

Pottery can be used to date archaeological sites. This is especially important at sites where written records cannot offer chronological references, either because they cannot be found or because they remain undeciphered. A famous example is on the island of Crete, where Arthur Evans was able to date the excavation of the Palace of Knossos based on imported Egyptian artefacts that were found there, including pottery, allowing the researchers to extend the Egyptian chronology to Crete. This brings us to another important aspect of pottery: it can provide evidence of trade and exchange networks. During the excavations on Crete, Arthur Evans also proved trade and cultural links between Crete and Egypt on the basis that Egyptian artefacts were found in Crete and also Cretan pottery was identified in Egypt.

Pottery can be analysed on the basis of several features: shape, type of surface, the colours, drawing patterns, and decorative styles. All these elements, studied in detail for each particular culture and time, can help to understand the artistic development of a society and may also enable specialists to identify pottery fragments when they are found in places far away from their production centre, reflecting trade activity and exchange networks.
