  • Patent number: 4975301
    Abstract: A method of decorating a glass substrate that has conductive coating applied thereto as electrically resistive heating elements comprises applying to said glass substrate a glass enamel composition comprising 5 to 25 percent by weight glass coloring agents, 1 to 25 percent by weight of a metal that will be resistant to rapid oxidation under the conditions in which the glass enamel is fired, and the remainder a soda free flux glass. The conductive coating composition is next applied and comprises finely divided conductive noble metals including silver, and a glass binder. The glass enamel composition and the conductive coating composition are fired onto the substrate. The glass enamel and conductive coating do not visibly react and the conductive coating cannot be seen through the glass enamel.
