Sully Sculpt and Dry Air Dry Sculpting Clay is a smooth non-toxic clay that is versatile and is suitable for use by Professional Artists, Students and Home Hobby use. This clay can be used for free hand sculpting, for use with common pottery techniques and used with clay tools, stamps or moulds. The clay air dries in approximately 24 hours depending on thickness and does not require heat or firing to cure. It is suitable for creating detailed works including figurines, jewellery beading, model making, kid's craft and much more. Once dry the clay can be decorated with paint or marker pens, varnished, sanded or drilled. Massage your clay until it is soft and flexible. Shape the soft clay with tools or by hand as required. Work on a non porous surface such as metal or plastic. Add a drop of water if clay begins to dry out too fast while working and also moisten fingers. Wrap your project in plastic wrap and cover with a damp cloth for any short rest periods. It's recommended you place your excess clay into a resealable airtight container when not in use. Wash your work surface and any clay tools with water after each use.
