in cold water, and finally reheating and forming the article into the desired shape.     I am further aware that it is not new to attach powdered glass to the surface of sheets of glass by first causing it to adhere thereto by gum or cement and thereafter fusing or vitrifying it to the sheets. Articles of such character, which I hereby disclaim, differ both in their method of manufacture and in their finished state from incandescent lamps in accordance with my invention, the latter being formed without the application of heat in the connection of the facing, and thereby being exempt from risk of fracture of the bulb, and the structure of the bulb not being in any wise affected by the facing or its connecting medium.

I claim as my invention and desire to secure by Letters Patent--     In an incandescent electric lamp, the combination of a bulb, a facing of fragments of transparent or translucent material, and a coating of material infusible at the maximum temperature to which the lamp is exposed and insoluble in water, said coating securing the facing to the outer surface of the bulb, substantially as set forth.     In testimony whereof I have hereunto set my hand. FRANK MOORE. Witnesses:     J. SNOWDEN BELL,     R. H. WHITTLESLEY.
