The soda spars are used in glasses and glazes, and the high potash spars in whiteware bodies. Potassium feldspars (KAlSi 3 O 8) enable the broadest firing range and the best stability of the body against deformation during firing. Sodium feldspar (NaAlSi 3 O 8) exhibits a lower viscosity than potassium feldspar when melted at a given ...
