Cold porcelain is a popular, non-toxic, air-drying modeling clay made from cornstarch and white glue, not actual porcelain, that hardens at room temperature without a kiln. It dries to a hard, smooth, porcelain-like finish, ideal for delicate crafts like jewelry, figurines, and embellishments, becoming durable yet soft enough to mold for detailed work, hardening as it dries.
