Self-Hardening Clay

November 11, 2010 Teachnet Staff 0

Self-hardening clay is available in five pound boxes at hobby stores, dries on its own when left uncovered in about a week, and is paintable. This clay is great for a first-time art project if no kiln is available, and dividing the five pound cube into eight equal sections gives students a large enough piece to make a small coiled pot.
