CLAY - Storing.
Clay storing. Clay can be kept for a long time in a plastic state by keeping it in the unopened plastic bag in which it has been purchased. With leftover pieces of the same type of clay, knead and roll them together, and to keep the clay in a damp state, put it in a plastic, airtight container. Plastic buckets with flat, airtight lids are very good as they can be piled one on top of the other.
