This site has an amazing array of any topics on clay, pottery, porcelain, ceramics, etc., including firing, shrinkage, drying techniques, and so-on, very comprehensive:

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.
When you heat clay it turns into a pot
Yes any pottery and ceramic item made of clay shrinks in drying and each firing stage.
pottery pieces crack during drying because the clay shrinks too fast and unevenly. If drying is controlled by wrapping pieces in plastic and allowing them to dry slowly, they won't crack usually.
Dry clay can be recycled by putting it in water. This will remoisten the clay and allow it to be kneaded and molded. Once clay has been fired it can no longer be recycled. Fired clay can be soaked a long time and will not dissolve.
As clay dries it shrinks and different types of clays shrink different amounts. In my class, we use a red stoneware that shrinks about 12%.

If the sun shrinks there would be a huge black hole sucking in all the planets with it and any survivors would freeze. Sounds like fun!
