Abstract
In a process for the manufacture of glass articles, mainly glass bottles, said glass articles are strengthened by an ion exchange method, which involves exchanging alkali metal ions from the surface of said glass articles by other alkali metal ions provided by an ion exchange medium applied to the surface of said glass articles, which provides a strengthening layer in the surface of said glass articles. This ion exchange method is greatly improved by supporting said glass articles on a grounded metallic conveyor; charging electrostatically an ion exchange medium; and spraying a flow of said electrostatically charged ion exchange medium on said glass articles, in the line of production before the stage of article thermal treating. This promotes a uniform application of the ion exchange medium in the surface of said articles.
