摘要： APPLYING A DECORATIVE COATING OR DESIGN OF ELECTROCONDUCTIVE MATERIAL TO A GLASS BASE. WHEN THE BASE IS TRANSPARENT, THE RESULTING ARTICLE IS USEFUL AS A READILY HEATED WINDOW FROM WHICH FOG AND ICE CAN BE READILY REMOVED ON HEATING. A FRIT COMPOSITION HAVING AN APPROPRIATE COEFFICIENT OF EXPANSION, AN APPROPRIATE MATURING TEMPERATURE, AND WHICH MATURES INTO A ROUGH, POROUS COATING, IS APPLIED TO A GLASS SHEET SURFACE IN THE CIRCUIT PATTERN DESIRED, THE SHEET IS HEATED AND THEN COOLED RAPIDLY TO PRODUCE A TEMPERED GLASS SHEET HAVING A ROUGH, POROUS FRIT COATING CONFORMING TO THE PATTERN DESIRED FOR THE ELECTROCONDUCTIVE HEATING CIRCUIT, AND A CONDUCTIVE METAL COATING IS SELECTIVELY DEPOSITED ON THE ROUGH, POROUS FRIT BY ELECTROLESS PLATING. THE FRIT MAY BE SENSITIZED BY INCORPORATING A MINOR AMOUNT OF A SENSITIZING METAL THEREIN OR BY APPLYING A SENSITIZING COMPOSITION.

摘要： THE INVENTION COMPRISES IMPROVEMENTS IN MAKING IMAGE-PLANE PLATES OF GLASS STAINED ON ONE SURFACE THEREOF, IN ACCORDANCE WITH WHICH IMPROVED RESOLUTION AND/OR THE ADVANTAGES ASSOCIATED WITH HAVING A PLANAR PLATE SURFACE ARE OBTAINED BY USING THE SCREENING ACTION OF TIN OXIDE, WHICH PREVENTS METAL STAINING OF THE GLASS.
