A method for applying a cold end lubricating coating to glassware articles on which a hot end metal oxide coating may have been applied includes conveying the glassware articles through a heated vapor deposition chamber provided by thermally isolating a conveyer portion. Lubricating coating material, such as a fatty acid, is liquified in a heated reservoir inside a heated tank which also contains a heated vapor chamber. The reservoir and vapor chamber are separated by an internal wall of the tank. At least one flow of the liquefied coating material is directed to at least one vaporizer positioned on the tank adjacent to the reservoir and vapor chamber. The liquefied coating material is vaporized by feeding a flow of pressurized air to each vaporizer such that vaporous particles of liquefied coating material are entrained in the air. The air and entrained vaporous particles are directed to a vapor deposition chamber. The glassware articles are coated by impingement of the vaporous particles on them, and the glassware articles are then cooled such that the coating solidifies.

An apparatus for forming a coating on glassware articles comprises a source of pressurized air and source of liquid coating material. The source of liquid coating material includes a reservoir and a vapor-forming chamber. An adjustable gas pressure regulator provides a regulated gas pressure in the reservoir and a regulated flow of liquid coating material out of the reservoir. A plurality of vapor-forming atomizers are positioned and configured to atomize the liquid coating material and direct the coating material vapor into the vapor chamber. The apparatus further includes a vapor booth and a conveyor operable to convey glassware articles to the vapor booth to be coated. A plurality of fans provide circulating flows of coating material vapor within the booth and along the conveyer portion.
