ABSTRACT:
A method for lubricating glass contacting surfaces of glass forming equipment is disclosed. The method comprises the steps of delivering MAPD gas to a venturi at a low pressure, preferably below 10 p.s.i., and delivering oxygen to the venturi at a lower pressure, usually is half or less than half of the pressure at which the MAPD gas is delivered to the venturi. The MAPD gas and the oxygen are mixed in the venturi and delivered to and through a nozzle which is directed toward a glass contacting surface. The mixture is ignited as it leaves the nozzle; its flow is controlled so that the temperature of the flame is between approximately 1500 and 1800 degrees K. By controlling the temperature of the flame, the method is operable to deposit on the glass contacting surface a lubricating coating of graphite including a substantial percentage of flat plate graphite.
