As the potter is working, something goes wrong. The clay was perfectly formed just a minute ago. But suddenly, it wobbles, warps, and tumbles over. What would cause a pot to collapse like that? Sometimes, if the clay has been pulled and stretched too much, water seeps in between the flat plates that make up the clay and weakens its structure. It's called "clay fatigue." And it may seem like a disaster. But the potter is never daunted. There is always something he can do. He scoops up the clay, takes it over to the wedging table, and begins again, pressing and turning, eliminating pockets of air, softening dry places, returning strength and integrity to the entire lump of clay. Then the potter attaches it to the wheel head, sets the wheel spinning, and simply starts the process all over again.
