This is the original polymer ovenbake clay, available in the White formulation. Original Sculpey works and feels like ceramic clay but will not dry out when exposed to air. Shape into desired form and bake at 275F for about 15 minutes per 1/4in of thickness. Once cooled, your project can be sanded, drilled, carved, painted with water-based acrylics or glazed. This formulation is ideal for sculpture and children's projects.
