composition will consist of 50% clay, 25% quartz and 25% feldspar. China clay imparts rigidity to the ware and feldspar, as a flux provides a glassy phase in the microstructure. Quartz on the other hand lowers both drying and firing shrinkage and imparts rigidity to the wares. Mullite and glass constitute the major phases of porcelain materials.

The first step in the hydrolysis of feldspars is for the feldspar to dissolve in water, which occurs better in acidic or basic solutions and less so in neutral solutions. The rate at which feldspars are dissolved determines how easily they weather. Clays are formed when dissolved feldspar reacts with H+ or OH ions.
