ABSTRACT:
A process for forming a glazed ceramic substrate, more particularly for forming a particular surface finish and/or surface pattern in the glass. The process consists of preparing a ceramic mixture which includes a basic oxide, such as Al.sub.2 O.sub.3, and a glass, forming the substrate as by molding, pressing, or doctor blading and lamination, and sintering in a non-reactive atmosphere on a setter tile that is non-wettable by the glass. During the sintering operation the glass becomes molten and flows downwardly under the influence of gravity through the ceramic particles. The glass flows to the setter plate to conform to its surface configuration, forming a glazed surface on the substrate.
