Coiling is a method of creating pottery. It has been used to shape clay into vessels for many thousands of years. To do this, the potter takes a pliable material (usually clay) then rolls it until it forms a coil, or long pliable cylinder. By placing one coil on top of another, different shapes can be formed.
Why Does clay have a memory?
Memory is caused by the loss of water content. As moisture is lost, the yield point increases until the maximum green strength is achieved. As drying occurs, the uniform negative charge reverts back to neutral, which in turn causes disorientation of the particles. Once the water leaves the clay, so does memory.
