Abstract

This glass paste, when applied to a high alumina, ceramic substrate in a given pattern as shown in A and fired at 1600-1650 degrees C for one to two hours, forms a shallow depression or cavity in the substrate. Such cavity has the exact configuration of the deposited pattern as shown in B. The glass paste comprises, by weight, 75% of solids and 25% of an inert liquid vehicle composed of #163-C squeegee medium from L. Reusche & Co., beta terpineol, and ethyl cellulose. The solids include, by weight, up to 10% CaO, up to 20% MgO and at least 70% SiO(2).
