You don’t need to store polymer clay in airtight containers, since it contains no water to evaporate. However, it should be wrapped or covered to prevent dust and lint from getting on it, and kept away from heat and sunlight. Be careful about storing polymer clay in plastic containers or plastic wrap.
Do clay sculptures need to be fired?
Self-hardening clay, also known as air-dried or non-firing clay, is a direct modeling material that cures naturally and does not require mold making and casting to achieve a finished piece. In addition, this modeling clay does not need to be fired in a kiln.
What does air dry clay not stick to?
Air dry clay will not stick to flat metal surfaces but it will stick to rougher metal surfaces or metal wire. It will continue to stick to metal surfaces when it has dried but only if the surface is rough enough to give the clay enough to stick to.
What clay is used for sculptures?
Coarse clay is a better choice for hand-building and sculpting as the clay holds its shape better and reduces shrinkage, reducing cracking or warping. For wheel throwing, coarse or grainy clay can cause hand abrasion, so ultra-fine or no-grain clay is the best option. A fine smooth clay also gives a more matte finish.
Why is my air drying clay cracking?
Cracking is normal in air dry clays: it’s caused by shrinkage because of the loss of the water inside the clay body. Cracking in air dry clay is typically caused by sculpting over an armature or using a lot of water, either to mix the clay or to help it adhere onto a previous layer.
Why is my clay cracking as it dries?
Pottery clay cracks when drying if some parts of the piece dry out more quickly than others. When clay dries, it shrinks. If one part of the clay is shrinking faster than the other, this puts an internal strain on the pottery. The clay cracks to cope with the strain.

Is it OK to use moldy clay?
Two of the most common types of mold that can be found are green mold, which can be seen as a good thing as it can add moisture (and plasticity) to the clay, and black mold, which is more tricky as it has a darker colorant.

Which is better polymer clay or air dry clay?
As a whole, the main difference between air dry clay and polymer clay is that polymer clay is a type of thermoplastic that hardens once it is baked in a regular oven. Air-dry clay is a clay and glue mixture that air dries. Polymer clay is more durable and water-resistant while air dry clay is cheaper.
Why does my polymer clay break after baking?
Sometimes your polymer clay beads will break even after you’ve baked them. If the temperature is too low your polymer clay will not cure properly. Improperly cured clay is very weak and brittle, and susceptible to breaking. Certain polymer clay brands are more brittle than others.
Does polymer clay harden after baking?
Most polymer ‘oven clay’ hardens and cures with sufficient heat for a long enough time. There’s no shortage of crazy ways to cook clay. It’s been hardened with heat guns, cooked in electric roasters, tossed in fry pans on a bed of plaster of paris powder, boiled, fried, and even microwaved.
