Abstract

A process is provided for employing scrap glass (cullet) having an organic coating thereon in an overall process wherein molten-glass forming ingredients are converted into agglomerates and the agglomerates preheated to an elevated temperature prior to melting in a glass melting furnace. The organic coating is pyrolized, i.e., thermally decarbonized, during the preheating of the agglomerates.
