Plaster Sculpture

2 cups water
2 cups Plaster of Paris
3 cups vermiculite

I purchased vermiculite at Earl May gardening center. Make sure you get the kind without fertilizer. The students should be fine if they aren't eating it or breathing in the dust. The mixture should be thick enough that there isn't any dust.

Pour the mixture into your containers to dry. We used plastic yogurt and sour cream containers.

We let ours sit for an hour and it was pliable with our fingers. After four days it was completely dry and ready to carve.

The best item to carve it was a nutcracker pick.
