Process, not Product
from Just Add Light and Stir, December 28, 2010
A disposable art material, intended for playing but not for keeping, is playdough. It's not edible, it won't keep for years, and baking it makes it brittle without extra strength. It's not an investment in permanence, which can be therapeutic in itself for some people.
Æsthetically, it's nice for children. It starts off warm (starts off hot), feels good, and smells good, especially with some of the additives Pam Sorooshian recommends here. The play is soothing and easily shared, It can all be saved in ziploc bags for a while, and eventually thrown away.
Meanwhile, children can discover color combinations from mixing bits of different batches. They can experiment with making coil pots and little sculptures, or just generally squish the dough through their fingers. If your children are older, they might still have big fun. If your children are grown, you-the-mom (or dad) might find some unexpected entertainment yourself.
