Cornstarch Clay Art

To be honest with you, I am getting a little confused by all these different clay recipes. Cornstarch clay for instance is also referred to as cold porcelain, but Polymer clay and Play Dough pop up as well, when doing a search for cornstarch art. What's up with that???

Let's see if we can get some clarity in all of it. As far as cornstarch clay goes, I found the following recipes:

2/3 cup salt, 1/3 cup baking soda, 1/2 cup cornstarch, or:
1 cup cornstarch, 2 cups salt, 1 1/3 cups cold water.
I suppose these are just guidelines and you can mix and match until you found the consistency which works for you.

Mix salt and baking soda with 1/3 cup of water and bring to a boil. In a small bowl, combine the cornstarch and 1/4 cup of water and stir well. As soon as the salt mixture boils, remove it from the heat and add the cornstarch mixture. Stir vigorously for a couple of minutes, so the clay thickens. Spoon it on a sheet of waxed paper and let it cool before working with it.

Just like salt dough and other clay, it is easy to use it for all kinds of projects and even though it is not really edible, it is safe for children to play with.

The clay can either be air dried (give it at least several days to harden), or baked in the oven on 225 degrees, until it is hard. It can then be painted as well.

So far, the only difference I found between cornstarch and salt dough were the ingredients. Concerning cold porcelain clay; now that requires a little more research!
