Things You'll Need
A mold is a negative, hollowed-out image of a figure used to create multiple, identical sculptures which you can display, give to friends or family members, or sell in a specialty shop. One type of clay often used to create molds is polymer clay. Polymer clay is a versatile craft clay that can be baked in a conventional oven and used to mold any number of objects. For example, a mold of a decorative pipe out of polymer clay can be fired in a basic conventional oven and reused multiple times.
Knead a 6-inch ball of polymer clay for five minutes to remove any air bubbles. Polymer clay can be purchased at craft stores or art supply stores.
