At Homespun and Hands-On® our acrylic pottery glaze adds strength to the integrity of our air-dry clay and makes it water-resistant. It also adds another layer of fun to the project as budding artists are amazed when it brushes on opaque and dries perfectly clear! Our 1 oz. glass pot of glaze covers approximately 50 square inches of clay rolled to 1/2” thickness. Conforms to ASTM D-4236 and is safe for educational use.
