912,752. Tempering and coating glass. WARTENBERG, E. W. June 2, 1960 [June 8, 1959], No. 19516/60. Class 56. Glass is heated and quenched in a bath of a liquid in which is dissolved a substance which reacts with the surface to produce a coating. Coating substances include water-free metal halides and oxy-halides, particularly of metals of Groups IV and V, such as stannic chloride, silanes, particularly phenyltrichlorsilane, and organo-metallic compounds such as zinc ethyl. The solvent may be monochlorbenzene, carbon tetrachloride or amyl alcohol. Phosphorus trichloride or phosphorus oxychloride may be added to the bath to render the coating electrically conducting. The thickness of the coating may be controlled by varying the strength of the coating solution.
