What happens if Clay gets too wet?
Wet clay contains a large amount of water, a minimum of 25%, actually. When clay starts to dry, water evaporates from it. As this happens, the particles of clay are drawn closer together resulting in shrinkage. Porcelain clay has very fine particle sizes which makes it very plastic and also shrinks the most.
