  • Patent number: 4431692
    Abstract: The present invention relates to improving the scratch and abrasion resistance of glass surfaces, and especially the exterior surfaces of glass containers such as bottles, jars, tumblers, stemware, and the like. Hollow glassware for container use is subject to abrasive contact with similar articles as well as handling equipment in the normal processes of manufacturing, packaging, filling and shipping. This invention further relates to providing improved abrasion resistance to glass articles and particularly hollow glass containers which are treated by the present hot-end process while retaining considerable heat of formation. The articles are then able to be overcoated at a lower temperature such as by organic materials to further improve their lubricity and durability. The subject process of providing a primary coating is markedly more economical than presently known processes.
