ABSTRACT:
In order to manufacture large-size porous shaped bodies of low density by swelling clay masses by supplying heat thereto, a plate-like, self-supporting clay mass is used, it is given an all-round support by direct acting, multiple linear solid body contact and at the same time maintained in constant motion relative to the support, and the surface of the swelling clay mass is subjected to constant oxidation by the supply of oxidizing hot gases to the surfaces of the plate-like moving clay mass.
