This is an important part of the process, as if there is any air within the clay, the shape you give it will not make a difference and it will easily break.

Can air dry clay break easily?
While air-dry epoxy clays harden the best (and fastest)—becoming tough enough to drill holes in it without creating cracks—other air-dry clays can be fragile and prone to cracking.

What clay is heat resistant?
Fire clay is resistant to high temperatures, having fusion points higher than 1,600 °C (2,910 °F); therefore it is suitable for lining furnaces, as fire brick, and for manufacture of utensils used in the metalworking industries, such as crucibles, saggars, retorts and glassware.
How long does air dry clay take to dry in the oven?
For a small 5in sculpture, about 15 mins will generally do, while a larger one will need repeated bakings. I never leave the oven on for longer than 20-25 mins at a time to prevent burning the clay. Optimal technique: turn the oven off after 15-20 mins and leave the sculpture in the oven to cool and cure.
Can you paint air dry clay before it dries?
Can you paint air dry clay before it drys? The short answer is no, you should not.

The paint can also lead to the clay not drying evenly which can in turn cause cracks if you are unlucky.

What type of clay is food safe?
For pieces made from lowfire clays, any surface that comes in contact with food or drink must be covered with a foodsafe glaze that has been correctly fired in order to be considered foodsafe. Even when fired, lowfire clay remains porous enough that fluids may penetrate the surface and soak into the clay.
