How do you dry pottery quickly?
Using a heater, hair dryer, or other hot air machine can cause serious cracking, especially if the clay is already hard or dry like leather. It is best to dry slowly and evenly. If the piece dries too quickly, cover it loosely with plastic. If the humidity is too high, cover with newspaper, then plastic.
What kind of clay can you bake in the oven?
Oven-baked clay, commonly known as polymer clay or Sculpey, is made from a synthetic material containing PVC powder, plasticizers, binders, fillers, lubricants, and pigments. When placed in the oven, the powdered PVC softens into a plasticizer, forming a solid plastic mass.
Why did my pottery explode in the kiln?
The main reason ceramics explode in the kiln is that residual moisture remains in the clay body, even though it appears to be completely dry. Once the kiln reaches 212F, the moisture begins to turn to vapor. It expands very rapidly and the pottery shatters to accommodate the steam.

Why does my pottery crack?
Cracks are primarily caused by uneven drying of the piece. This means that some parts of the ceramic will shrink more than others. The key to avoiding these pitfalls is to create a consistent environment for the piece to dry and to undertake the necessary preparations to ensure that the entire piece dries at a similar rate.
What do you put on clay so it won’t crack?
