For later reference:

Baking Soda Air-Drying Modeling Clay

1. Pour 2 cups Baking Soda and 1 cup of Cornstarch into a saucepan.
2. Add 1¼ cups cold water and keep mixing.
3. Add food coloring if desired.
4. Cook over medium heat, stirring constantly until mixture is the consistency of mashed potatoes (about 10-15 mins).

Also called "cold porcelain". Makes a soft white modeling clay that takes impressed detail well, very suitable for terrain rollers. The clay can be coloured when made, and takes acrylic paint well. It will take a day or two to harden.
