A glassware coating process and apparatus including ware handling, heating, coating and transfer equipment that is continuously operable to apply a coating of thermoplastic polymer resin to the exterior surface of the ware. The apparatus, among other things, includes a clamping mechanism for gripping heated ware about the finish thereof, which mechanism is immersible in a fluidized bed of the thermoplastic polymer resin along with the ware. Means feed pressurized gas to separate reciprocable cooperating elements of the clamping member to both cool said member and to inhibit polymer deposition on the grasped portion of the wave.
