In pottery, a potter's wheel is a machine used in the shaping (known as throwing) of clay into round ceramic ware. The wheel may also be used during the process of trimming excess clay from leather-hard dried ware that is stiff but malleable, and for applying incised decoration or rings of colour.
Ancient Egyptian pottery includes all objects of fired clay from ancient Egypt. [1] First and foremost, ceramics served as household wares for the storage, preparation, transport, and consumption of food, drink, and raw materials.
The clay is then kneaded by the potter and placed on a wheel. Once the clay is on the wheel the potter can shape it into any of the many shapes shown below, or anything else he desires.

Pottery techniques include the potter's wheel, slip casting and many others. Methods for forming powders of ceramic raw materials into complex shapes are desirable in many areas of technology. For example, such methods are required for producing advanced, high-temperature structural parts such as heat engine components, recuperators and the ...
