Clay softener improves the texture of dry, crumbly clay, creating the perfect consistency. Rescue old unbaked clay! Sculpey dilutant is a softening agent which will improve the texture of clays that have become dry and crumbly. Use sparingly by adding a few drops and kneading into the clay until it softens. Also great as an adhesive agent, apply sparingly to parts that will be attached to each other to increase the clay to clay bond!
