Professor Paul Mueller demonstrates the manufacture of a pinch pot. You will see a series of still pictures which go from a lump of clay to a pot ready to be fired. Click on each image to go to the next one.

Rotating the pot about his thumb, he widens the hole while maintaining a relatively smooth interior and exterior surface.

...and the bottom is sliced off to provide a flat base.

An ugly but functional pot holds water. Clay is added to the water to make a thin soup called a slip. A sponge is used to coat the surfaces of the pot, which provides a smooth surface.

The walls are so thin that they must be supported from the inside.

After drying for a day, a smooth stone is used to burnish the surface. This provides a smooth, glossy, less porous finish.
