Abstract
Abstract SCRATCH RESISTANCE OF GLASSWARE IS INCREASED BY COATING THE GLASS SURFACE WITH TETRAALKYL TITANATE. THIS COATING SHOULD BE PLACED ONLY ON THE BARREL OF THE GLASSWARE AND NOT THE FINISH OF THE GLASSWARE. CONTROLLED COATING IS ACCOMPLISHED BY PASSING THE GLASSWARE BETWEEN CLOSELY SPACED COACTING RECTANGULAR DISPENSING NOZZLES AND EXHAUST PORTS WHICH COOPERATE TOGETHER TO DISTRIBUTE THE COATING ACROSS THE BARREL OF THE GLASSWARE WITHOUT COATING THE FINISH OF THE GLASSWARE.
