Clay features an easy-to-use design that air dries to a hard solid to eliminate the need for baking or firing. Water can be added to the clay to soften or join pieces. When joining two pieces together, score or roughen both surfaces, then apply slip before pressing firmly together. To make slip, simply mix clay and water until it's the consistency of heavy cream. You can use most traditional clay sculpting techniques with this clay, such as coil, slab, pinch and score-and-weld. The wet clay takes impressions well from rubber stamps or textured materials. You can also press beads, small stones or other decorative items directly into the clay. Air-dry clay is similar to a porcelain clay body when wet and can be thrown on a potter's wheel by intermediate and advanced students.
