Compositions in the high clay area of the triaxial, feldspar, clay, Cornwall stone, were studied as slip coatings for a terra cotta body. Calcined English ball clay was used to introduce a portion of the clay content. The porosity, checking behavior, tendency to craze in the autoclave, and the relative compression of the slips are shown. A typical desirable slip was chosen and the effect of additions of various fluxes and coloring oxides was studied. Slips of this type seem to offer the terra cotta industry the possibility of vitreous slips with greater resistance to moisture crazing.
