Hi! We have been looking through many books to try and find the
types of clay that you are looking for and we have found several:

1) PLAY CLAY: Make up a large batch of Play Clay for hours of manipulative
fun. You need: 6 cups of baking soda
3 cups of corn starch
3 1/2 cups of water
1/2 cup of salt
You do: - stir all of the ingredients together in a
sauce pan.
- cook on medium heat, stirring occasionally
until the mixture bubbles and thickens.
- then spoon out onto a board, cover with a
damp cloth and let cool.
- knead until smooth and divide into batches.
- add food coloring if you wish.
- after using, store your clay in a tightly
sealed plastic bag or a jar in the
refrigerator. (put a hole in small balls of
clay and fill them with water before storing.)
*Note: Play Clay hardens slowly w/out baking and can
be decorated with tempera or acrylic paint
for a permanent finish.

2) SAND SMUSH: Materials: 2 cups of sand
1 cup of corn starch
1 T alum
3/4 cup water
old pot, wooden spoon, newspaper
Process: 1) stir sand, corn starch, alum, and water in the
old pot until well mixed.
2) put the pot over low heat and stir constantly
until the mixture thickens to look like dough.
3) take the pot off the heat and let it cool
4) when the messy mixture cools, model it into
sand creations.
5) let the sand sculptures dry at room temp.
Drying time will vary according to size of the
6) expect anywhere from 2 to 5 days.

Try this: When the masterpiece is completely dry, sand it
very gently with fine sand paper. This will
remove loose grains and give the piece a smooth

Your creation can be painted, painting with a
small sponge will give your work a marbled effect.

Seal the finished creation with a finish of
white glue applied with a paint brush. Other
sealants include glazes, clear enamel sprays,
lacquers, or nail polish.

3) SAWDUST DOUGH: Materials: 2 cups sawdust
1 cup of flour
2 tsp white glue
2 tsp starch
large bowl, large spoon
Process: 1) mix the dry ingredients together
2) moisten with starch, glue, and water to
gain a good modelling consistancy.
3) model around a wire or stick frame. Pat
modelling mixture onto the frame, shaping as
4) Allow creations to harden for a permanent
work of art.
5) finish with a coat of shellac or paint.

We found these in Big Book of Fun by Carolyn Buhai Haas and Kid
Creations by Robynne Eagan. Hope they're helpful. Have fun!!
