Inorganic coatings for glass surfaces, especially hot end coatings for glassware, are produced by applying vapors of thermally decomposable metal compounds such as stannic chloride to the surface of glass at an elevated temperature and maintaining in a zone adjacent to and in close proximity to the heated surface a region of elevated moisture content. In a preferred form, separate streams of metal compound vapor and water vapor are directed onto the surface of the heated glass. |
