The cone rating of a clay or glaze is the temperature at which the clay matures. So if a cone 10 clay is fired to cone 5, the resulting pot will not be completely matured. This may or may not cause a problem, depending on what the piece is used for. For example, a cone 10 porcelain which is fired to cone 5 and not glazed will still be somewhat porous.

Which of the 5 stages of clay can be recycled?
As long as the clay has not been fired in the kiln, it can be recycled.
What temperatures does kilns for ceramics operate at?
Ceramic kilns fire to many different temperatures for the various types of clay and glazes. We use pyrometric cones to determine the correct firing of items. Clays and glazes are usually designated as Low fire or High fire. Low fire cones start at 022 or approximately 1094 F and most low fire ceramics are fired at cone 06 approximately 1911 degrees F. High fire pottery is generally fired from cone 5 or 2205 F to cone 10 which is approximately 2381 degrees F. Industrial ceramics may use much higher temperatures than a hobbyist kiln.
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.

How was clay fired?
This site explains the changes, the excerpt is a small explanation:The item is heated to temperatures up to 1170oC, during which time the clay undergoessome chemical changes and the silica and feldspar undergo physical changes. Thereactions of the clay can be summarised as follows:6Al2Si2O5(OH)4 ? 6Al2Si2O7 ? 3Al4Si3O12 ? 2Al6Si2O13kaolinite metakaolinite silicon spinel mulliteSilica and water (from the crystal lattice) are also expelled during firing, resulting in afurther 5 - 7% volume reduction. This silica mixes with the silica already present andmelts to form a glass. It is this glass, which also includes metallic ions from thefeldspar, that makes the ceramic item non-porous and water-tight.* The site: http://www.nzic.org.nz/ChemProcesses/inorganic/9C.pdf

What are the six stages of clay?
1. Slip - Potters glue. Slip is used to join clay to clay and to decorate. It is the consistency of toothpaste when it is used like glue and paint when it is used like a glaze. It is usually a make of clay and water. 2. Plastic or wet - The best time for pinch construction, stamping and modeling. Cool the touch. 3. Leather hard - The best time to do slab construction or carve. It is cool to the touch and has the consistency of hard cheese or leather. There are 3 sub-catagories within leather hard. A. Early - Still able to move clay slightly without cracking or damage. B. Middle - Can no longer move clay without cracking or damage. Good time to create texture or carve into clay. C. Late - Clay is still cool to touch, good time to do detail carving, clean edges, fine tune, etc. 4. Bone dry - The clay is no longer cool to the touch and is ready to be fired. 5. Bisque - Finished ceramics that has been fired once. 6. Glaze ware - Finished ceramics that has a coat of glaze for decoration or to make it vitreous.
