Air Drying, or Dry-Hard Clays do not require firing in a ceramic kiln to achieve hardness. When left out in the open air the clay begins to firm up in a few hours, and will become hard and strong in a few days. Clay can then be painted as you wish.
Do not fire in your kitchen oven, or fire in a kiln.
WED is a non firing clay, but does not dry hard as the Mexo White.
