Feldspars are important ingredients in clay bodies and glazes. In both applications, their primary function is to supply ﬂuxes to the formulations, but they also provide additional alumina (Al2O3) and silica (SiO2). Feldspars are naturally occurring minerals and are generally classiﬁed as either potash (potassium) or soda (sodium) feldspars based upon the predominant alkali metal element (the ﬂux) that is present. The minerals commonly referred to as lithium feldspars are not true feldspars, but they are aluminosilicates like feldspars and contain the ﬂuxing element lithium, and are used for the same purposes as the feldspars.
