Why is wedging clay important?

Wedging is to potters as kneading is to bakers, only we don't do it for the same reasons.

Basicaly it is mixing it up in a special way using the heals of the hands on a hard (wood or plaster) surface.
What are the two important causes of mechanical weathering?
Temperature changes make rocks expand and contract and it is one of the important cause of mechanical weathering. Water abrasion is the other important cause. Wind and moving water cause rocks to rub against each other and the rocks could well break into smaller pieces.
What is wedging clay?
Clay wedging is the act of preparing clay for the pottery wheel in order throw your pottery. wedging is accomplished by kneading the clay, usually on a plaster surface, until the clay is uniform in moisture and texture. Some potters like to cut the mass of clay and slap it down hard on the surface and then slap the 2 pieces of clay together with force. The idea is to get rid of any air bubbles and to make the mass of clay evenly moist. This will help the potter to form the clay on the wheel with interference of trapped air bubbles or hard lumps of clay which will cause the piece to be uneven. Also, air bubbles can explode when the piece is fired, especially if the piece is not bone dry.
