To make easy salt clay dough, combine 2 cups of all-purpose flour with 1 cup salt in a large bowl. Pour in 1/2 cup of water. Knead the dough, adding water if the mixture is too stiff or dry, until the dough is firm but easily maneuvered. To make it more sticky, add 1 to 2 tablespoons of wallpaper paste. For colored dough, stir in several drops of food coloring or food items, such as coffee, annatto or curry.
Wrap dough in plastic wrap or a resealable bag, and place it in the refrigerator for long storage. If the dough is too tacky when removed from the refrigerator, add some flour or salt. If it is too dry, add some water.
Another simple salt clay dough involves mixing 1 cup of salt, 2 cups of flour, 1 cup of water and 1/2 teaspoon of powdered alum. For extra pliability and longer lasting freshness, add 1 teaspoon of oil. Knead the dough, shape as desired, and then let it air dry or bake at 325 degrees Fahrenheit until the dough is browned. If you want to hang the sculpture, insert paper clips prior to baking.
Baked dough can be painted, and plastic varnish adds luster and long-lasting preservation. When combining the ingredients, add food coloring for extra color.
