Modeling clay that hardens when exposed to air. It is suitable for use in classrooms or for visual artists as an introduction to sculpture. The clay is shaped manually, and various accessories can be used. To prevent the clay from drying out, store it in an airtight container after use. It dries naturally in the air (within 24 hours) and does not require kiln firing. The clay can be smoothed easily and leaves no marks or peeling. It can be painted, varnished, wiped, polished, turned, and cut. Clay weight: 500 g.
