The pinch method is a pottery method performed by repeatedly pinching a soft-plastic clay mass in a sequence, eventually displacing the material into a desired formal configuration.

>Bowls can be made by inserting one's thumb intro the mass, then repeatedly pinching it with one hand while rotating it with the other until a semi-spherical bowl is formed.

At the beginning stages of this growth process, the clay walls are very thick and the capacity of the bowl miniscule as its volume is about the size of the creator's thumb. If one were to attempt filling this bowl with a steady drip of water, it would take only a few moments before it reaches its capacity and overflows.

As the artist continues pinching and material is further displaced, the walls get thinner, the object gets larger, and the volume of the bowl expands despite no material being added.

>It takes longer for the drips of water to fill up the bowl.

>You are the bowl and the water is time.
