Potter's wheel

technology Maturity 11-13 Next article →

A potter's wheel is a specialized machine used to shape clay into round ceramic objects. This specific shaping process is known as throwing.

Beyond shaping, the wheel is useful for trimming excess clay from pieces that are leather-hard. Leather-hard describes clay that is stiff but still malleable enough to work with. Potters also use the rotation to apply rings of color or incised decorations. This tool is a vital component in the creation of various arts and craft products.

To understand how throwing works, one must follow a specific sequence of movements. First, the potter must center a lump of clay on the rotating surface. Once centered, the potter opens a hole in the middle of the clay. This action creates a donut-shaped ring of clay around the base of the vessel. Finally, the potter raises and shapes the walls to reach the intended final form.

While most cultures spin the wheel counterclockwise with the right hand on the outside, Japanese traditions often spin clockwise with the right hand inside the pot.

There are also mechanical extensions of the wheel used for specific types of pottery. One method is called jiggering, which is used to create flat ware like plates. In jiggering, a shaped tool is slowly pressed onto plastic clay sitting on a rotating plaster mould. The tool shapes one face while the mould shapes the other. A similar technique is called jolleying, which is used to produce hollow ware such as cups.

Before the invention of the wheel, civilizations relied on manual techniques like pinching, coiling, and paddling. In the coiling method, potters roll clay into long threads and pinch them together. This process requires the potter to supply all the energy with their hands. Early potters often worked on mats or large leaves to allow them to rotate the vessel easily.

The oldest wheels, known as tournettes or slow wheels, were likely extensions of this manual rotation. Around 3500 BC in the Near East, these were turned slowly by hand or foot.

History shows a major shift with the development of the fast wheel in the mid to late 3rd millennium BC. This machine operated on the flywheel principle, using a heavy rotating mass to store energy. Potters would kick or push the wheel to provide angular momentum.

This allowed for the creation of thinner-walled pieces and more complex shapes, such as stemmed vessels. The ability to produce many more pots per hour marked an early step toward industrialization.

Scholars still debate the exact origin of the potter's wheel. A stone wheel found in Ur, Iraq, dates to approximately 3129 BC. However, a wheel from the Cucuteni–Trypillia culture in western Ukraine dates to the middle of the 5th millennium BC, making it the oldest found.

Egypt is also considered a possible origin point. Around 3000 BC, Egyptians lengthened the turntable shaft and added a flywheel. This innovation led to the counterclockwise motion that is almost universal today.

In Japan, the technology arrived during the Asuka or Sueki period between 552 and 710 CE. This era saw more sophisticated wares and higher firing temperatures in rudimentary kilns. This progression continued through the Nara and Heian periods. Higher temperatures allowed for the use of new glazes in colors like green, white, and yellowish brown.

Meanwhile, Chinese pottery history spans from the Neolithic era around 4300 BC to 2000 BC. China focused heavily on porcelain, especially during the Ming and Qing dynasties from 1644 to 1911.

Modern technology has introduced electric wheels, which are common in schools and studios.

These wheels use a motor and often feature a foot pedal to control speed, similar to a sewing machine. In some places, like Jingdezhen, China, massive wheels allow for incredible scale. Three or more potters may work on a single large vessel at the same time.

This shows how the wheel continues to connect individual craftsmanship to large-scale production.
