Pottery

arts Maturity 7-9 Vital Level 3 Next article →

Pottery is the process of forming objects from clay and other raw materials. These objects are then fired at high temperatures to become hard and durable. The term pottery can also describe the place where these items are made. According to ASTM International, pottery includes all fired ceramic wares containing clay. This excludes technical, structural, or refractory products. People use pottery for many things, including tableware and decorative ware. It is also used for sanitary ware and industrial needs. For example, it can serve as electrical insulators or laboratory ware.

The making of pottery involves several specific steps. First, a potter forms a clay body into a desired shape. This material is often called the paste or the fabric. A potter may decorate the object before or after the firing process. Next, the object is heated in a pit, a bonfire, or a kiln. The temperature usually ranges from 600 to 1,400 degrees Celsius. This intense heat induces chemical reactions that change the material permanently. These reactions increase the strength and rigidity of the finished object.

Firing
Firing

Pottery is traditionally divided into three distinct types. The first type is earthenware, which is fired at low temperatures. It is often fired below 1,200 degrees Celsius. Because unglazed earthenware is porous, it can absorb liquids. Reddish earthenware used for sculpture is often called terracotta. The second type is stoneware, which is fired at higher temperatures. It is fired between 1,100 and 1,200 degrees Celsius. This makes stoneware very tough and non-porous.

The third type is porcelain, which requires the highest temperatures. It is heated in a kiln between 1,200 and 1,400 degrees Celsius. Porcelain is known for its toughness, strength, and translucence. This unique quality comes from vitrification and the formation of mullite. The Chinese developed porcelain very early in their history. By the Tang dynasty, between AD 618 and 906, porcelain was already being exported. It reached Korea and Japan by the end of the 16th century.

Pottery is one of the oldest human inventions. Some ceramic objects, like the Venus of Dolní Věstonice, date to 29,000–25,000 BC. The earliest known pottery vessels were found in Jiangxi, China. These vessels date back to 18,000 BC. Other early artifacts have been found in many places. These include Jōmon Japan in 10,500 BC and the Russian Far East in 14,000 BC. Sub-Saharan Africa shows pottery from 9,400 BC. South America has pieces from the 9,000s to 7,000s BC.

Archaeologists use pottery to understand the past. Because pottery is durable, it survives long after organic materials decay. Scientists use fabric analysis to study the clay body. This involves looking at the clay matrix and clay inclusions. The matrix consists of grains smaller than 0.02 mm. The inclusions are larger grains visible to the naked eye. By studying these, researchers can learn about ancient technology and trade. They can also use carbon dating to find the age of a site.

Ceramic vessels are also very important for cooking. They have excellent thermal retention and distribute heat evenly. Unlike metal, ceramics emit far-infrared radiation. This radiation penetrates food deeply, which is great for slow-cooking. Porous earthenware, such as a tagine, can release moisture as steam. This helps to tenderize ingredients and preserve flavors. Vitrified stoneware provides a dense surface that resists acid. This ensures that the taste of the food remains pure.
