Drying time is about 1-2 days, depending on thickness of your creations. If the clay feels cold, it is still expelling water and is not completely dry. The clay must not be fired, but will dry into a stable and robust shape without heat curing. For best results, this clay should be kneaded thoroughly before use and have a minimum thickness of 1 cm. Supplied as an individual brick.
