  • Apparatus for making mirrors
    Patent number: 4365584
    Abstract: A method and apparatus are provided for silvering glass at higher than normal deposition efficiencies by premixing a silver solution, a caustic solution and a reducing solution and immediately spraying the mixture onto a glass to be coated through a large orifice spray nozzle. The spray nozzle is one which provides an orifice large enough to pass the total volume of mixtures required for silvering through a single opening with a defined spray pattern, preferably in the form of a conical spray.
    Type: Grant
    Filed: September 13, 1978
    Date of Patent: December 28, 1982
    Assignee: Falconer Plate Glass Corporation

  • Methods of manufacturing and protecting mirrors
    Patent number: 4255214
    Abstract: A method is provided for protecting silver and copper coated mirrors against oxidation and corrosion by passivating the metallic coating prior to applying a protective organic coating. The silver and copper can be passivated by applying an effective amount of tolyltriazole to the metal surfaces by spraying, wiping, flooding or the like.
