Using the isothermal method and press softening measurements, the densification process of clays from the Westerwald deposits in West Germany was compared with that of a feldspathic body prepared from Japanese raw materials. The clays from the Westerwald deposits completed the densification at around 120℃ lower than that of the feldspathic body and showed high deformation resistance as well, the softening deformation being 1/3 that of the feldspathic body. This is closely related to the fact that 90% of the illite which is flux component and 22% of the quartz particles are concentrated in the range lower than 2μm. In addition, it is believed that the composition of mullite is different, as judged by the marked difference in the shape of the crystallized mullite.
