ABSTRACT:
A process of forming a glass sheet by coating a portion of a glass sheet with a ceramic color paste, then forming a silver paste over a portion of the ceramic color paste and then firing the sheet. The ceramic color paste is of a composition which prevents the migration of silver ions to the glass plate during the firing. Migrated silver ions causes discoloration in the glass. The ceramic color composition comprising, as inorganic components, from 40 to 95 wt % of a glass powder, from 4 to 40 wt % of a heat resistant pigment powder and from 1 to 30 wt % of a boride, a nitride, a carbide, lead sulfide or a mixture thereof.
