Abstract
Electrically conductive glasslike films have been produced on the surface of various types of glass and porcelain by heating plumbite-treated cellulosics while one surface of the plumbite-treated cellulosic was in contact with glass or porcelain and the other surface of the cellulosic was covered with either aluminum foil or powder. The heating was carried out in a closed oven with a limited availability of oxygen. The various glasses and ceramics treated by the process of this invention were imparted a conductive coating or surface which appeared to be rigid with respect to abrasion and grey with respect to coloration.
