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.
