Things You'll Need
Instructions
Turn on the oven to 350 degrees Fahrenheit. This will dry the clay safely and help strengthen it.
Line a metal baking tray with a sheet aluminum foil. Put your children's clay models on the aluminum baking sheet.
Place the tray into the center of the oven. Leave the clay models to dry for four hours, or until they're completely dry.
Turn off the oven. Leave the clay models in the oven ̵1; preferably overnight ̵1; while the oven cools.
Remove the clay models once the oven is completely cool. Your children can now paint their models.
