Air-drying clay is immediately ready for use after it has been removed from the packaging. The clay can be formed by modeling or using a mould. Then let the clay dry and the clay is then completely hardened. This clay does not need to be fired in the oven unlike polymer clay.
If the clay dries a little harder than your work, moisten the clay slightly by spraying some water and you can continue with your project.
Air-drying clay is often in white or other very light colors and can be painted with a good acrylic paint after complete curing.
