Hearty Clay is a light-weight, odorless, soft air drying clay that is ACMI certified non-toxic. No kneading is necessary. Great for intricate, detailed and delicate work; jewelry making, flowers, miniatures, dolls and embellishments. Hearty Clay allows for all water-based paints to be applied before the clay dries. Chalks, embossed powders and other dry agents are best applied when the project is dry.
