ABSTRACT:
This invention teaches a method for forming a tempered, coated, grooved and/or beveled decorative glass sheet. The decorative glass sheet includes a coating on a surface thereof and a groove or bevel formed in the surface. The coating is substantially registered with at least on peripheral edge of the groove or bevel such that the coating is not disposed within the groove or bevel. The decorative glass sheet is formed by applying a coating, preferably by screen printing, to a surface of the glass panel. The coating is fired so as to set the coating into the glass panel. A groove and/or bevel is formed in the coated surface. The glass panel is then tempered. Preferably, the step of firing the coating is followed by the step of cooling the glass panel at a rate sufficient to temper the glass panel and, more preferably, at a rate sufficient to induce heat strengthening.
