ABSTRACT:
Electrostatic coating methods and apparatus are used to coat the exterior surface of glassware and preclude deposition on the interior surface and mouth of the glassware. A preferred stearic acid coating electrostatically applied over glassware with a hot end coating provides a more durable coating, improves scratch resistance and can reduce the amount of hot end coating for improved scratch resistance.
