This is my favorite kind of clay. It’s solid as a rock after drying. I’ve used it to make little Goddess figurines and such. It’s good for making little tiles, (shells look good embedded in it), and midsummer sun coins. I don’t know if it’s water/weather-proof yet, but I’m going to test that out to make some offering bowls that I can leave outdoors.
2 cups sand
1 cup water
1 cup cornstarch
Mix sand, cornstarch and water in an old saucepan. (Add natural dyes if you want color.) Cook over medium heat, stirring constantly. Remove from heat when the mixture thickens. Turn the clay out onto your work surface. (Clean the pot while it’s still hot, or it will be really hard to get the residue out.) Let the clay cool some, but don’t wait too long or it will harden.
