A mould 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 speciality shop. One type of clay often used to create moulds is polymer clay. Polymer clay is a versatile craft clay that can be baked in a conventional oven and used to mould any number of objects. For example, a mould of a decorative pipe out of polymer clay can be fired in a basic conventional oven and reused multiple times.
