A metal oxide coating is applied to a hot glass surface by contacting the surface with a mixture of carrier air, vaporized solvent and a vaporized metal containing reactant. The mixture is directed against the glass through an elongated, converging slot-nozzle, the interior surfaces of which have an increasing radius of curvature towards the exit end, nozzle at a Reynolds number exceeding 2500 with the nozzle-to-glass spacing at least 1.25 times the characteristic dimension of the nozzle. |
