This material is prized as a porcelain ingredient because of its low iron content. It is used in casting and throwing porcelains of all types. At cone 6 for example, it is possible to make a vitreous body using 50-60%. However to get enough plasticity in such bodies, it is necessary to use ball clay or bentonite which can darken the color. If high plasticity is not essential, Macaloid and plastic kaolins can be used.
Another similar material is Nepheline Syenite.
