Sand Clay

When this clay dries, it resembles real rock. It is hard and grainy. Depending on the color of sand you use you can make different effects use white sand for a beach sandcastle. Use gray sand to create a granite look. Use yellow sand to look like sandstone. You can even add powdered tempera paint for some really outrageous colors. Lots of fun and full of creative potential!
