Explain why clay shrinks how much does clay shrink on average?
In the "Kilning" and "bisquing" processes, the moist clay loses water (Evaporates). The water makes up about 5-10 % of the clays' substance, thus, on average, clay shrinks about 15-20% after it is in its final finished stage.

What does leather-hard mean to potters?
The stage reached in the drying of clay when most of the water of plasticity has evaporated off, maximum shrinkage has occurred and the clay particles have come into contact with each other. It is at this stage that most surface treatments and some secondary manufacturing techniques, such as paddling, are executed, because the clay is still moist enough to allow alteration. Also known as green-hard.
Is pottery a malleable or a brittle material?
Clay is malleable if there is water present in the clay body. As clay dries it goes through several stages. First is wet clay, which is very malleable. Second is what I call the cheese hard stage. It is still slightly bendable without cracking. Third is the leather hard stage. At this stage clay cannot be bent without cracking but you can still add or subtract from the surface by carving or building up with wet clay. Fourth is the bone dry stage. At this point the clay is dry and can no longer be added upon or subtracted from. It can only be fired or reconstituted into wet clay. After firing, I'm sure you know that pottery is very durable.
