The composition of the porcelain clays is usually more malleable than the clays used for china ware. This allows for forming of more intricate and detailed shapes. China ware differs from porcelain not only in color shade, but also in the way it is fired. Where Porcelain becomes vitrified during the second firing (second firing is hotter than first firing), china ware is vitrified during a single firing. With the china, there is only a single firing.
