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.
