Dyeing clay can be messy. Make sure your hands and your work surface are protected from staining. Only work on disposable or washable surfaces, like a sheet of wax paper over a counter or a plastic cutting board. Wear plastic or rubber gloves, especially if you're working with oil paint or food coloring. Disposable gloves are best. Spend some time kneading and pressing the clay with your hands before you add the colorant. This will help it soften so it can absorb the color more quickly and evenly. Kneading means to repeatedly press your fingers into the clay.The time you spend kneading will depend on the temperature and altitude you're at, but it shouldn't take more than 5 minutes. You'll know it's done when the color is distributed evenly all through the clay. Be careful adding additional colorant--you shouldn't add more than a drop at a time. Be sure to knead the clay thoroughly after each drop!
