2 c. flour
2 c. salt
1/2 c. hot water
1 tbsp. powdered alum
1 tsp. cooking oil
Food coloring
Mix flour, salt and alum with hot water in a bowl. Add cooking oil and food coloring (if you want colored dough). Mix well. Use a little more water if clay is too stiff.
Model clay in shapes on wax paper. Allow to dry for several days. Drying can be speeded up by placing in a 250 degree oven for about 3 hours.
Wrap leftover dough in a plastic bag and store in refrigerator.
