PURPOSE: To improve the fine view seen from the rear side of a glass by providing an intermediate layer between a colored layer and a silver-contg. layer, and controlling the diffusion of silver into the glass pigment layer when both layers are simultaneously calcined in the glass wherein the colored layer is provided between the glass surface and the silver-contg. layer.
CONSTITUTION: A glass pigment is printed on the surface of a glass sheet, and the glass enamel contg. the glass frit having higher viscosity than the glass frit of the glass pigment at the calcination temp. is printed thereon. A silver- contg. paste is further printed thereon, and the printed layers are simultaneously calcined at the calcination temp. By this method, an intermediate layer formed from the glass enamel contg. the glass frit having higher viscosity than the glass frit in the glass pigment at the calcination temp. is provided between the pigment-colored lower layer and the silver-contg. conductive upper layer. Accordingly, the diffusion of the silver in the outer layer into the glass pigment or substrate glass can be controlled.
