Method of forming glass substrates with pre-attached sealing media

A method of producing a glass substrate with electrical conductors deposited thereon suitable for gas panel fabrication which comprises drawing a vitreous or crystallizing solder glass consisting essentially of, on a weight basis, 72% PbO, 15% B.sub.2 O.sub.3, 2% SiO.sub.2, 5% Al.sub.2 O.sub.3, and 6% ZnO and having a softening point of 800 .degree. F into at least one rod 3 - 40 mils in diameter, applying said rod to one surface of said substrate adjacent the periphery thereof, and pre-firing said substrate for a period of time and at a temperature sufficient to permanently attach the solder glass thereto in a highly sintered or glassy state which will reflow and seal at a predetermined sealing temperature.
