Beschreibung
Zusammenfassung:	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. The glass articles are exposed to a highly moisture reactive first constituent confined to the centre of the flow pattern and a less moisture reactive second constituent surrounding said first constituent. TiCl4 may form the first constituent with SnCl4 being the second constituent. 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.
