A process is disclosed for the manufacture of glass sheets, particularly electrically heated backlites (EHB's). The process includes the steps of selecting a glass sheet and then applying an opaque band to a surface of that sheet. The opaque band is formed from a radiation curable paste which includes both a filler material which can fuse to the glass sheet when heated to a fusion temperature and a radiation curable material which is heat decomposable into components which are nonreactive with the glass sheet when heated to a fusion temperature. The radiation curable material is cured thereby to form a temporary bond of the radiation curable paste to the surface of the glass sheet. As an optional step in order to form an EHB, a pattern of electrically conductive material is deposited on the surface of the glass sheet. This conductive material contains at least one component which is heat fusable with the surface of the glass sheet when heated to the fusion temperature. The glass sheet is passed through a heating lehr which heats the various elements to the fusion temperature whereby the fusable materials are fused to the surface of the glass sheet and the radiation curable material is heat decomposed into components which are nonreactive with the surface of the glass sheet. |
