Cold Porcelain is a "clay" or paste that can be made at home and is composed of white glue and cornstarch. Cold porcelain is known throughout the world by many different names. It is also known as porcelana fria, masa flexible, biscuit, pasta di mais, among others. It is soft, white and flexible and can be modeled into small figures or large. Hard and durable when cured.
Cold porcelain requires no baking to cure and air-dries at room temperature. As it dries, it will lose 15% to 20% of the original volume and this shrinkage must be considered when modeling.
