Beschreibung
Zusammenfassung:	A method of strengthening an edge of a glass article while maintaining the optical clarity of the major surfaces or protecting layers or structures deposited on the surfaces of the article. A protective coating or film of a polymer or polymer resin is applied to at least one surface of the glass article. The surface may either be melt-derived or polished, and/or chemically or thermally strengthened. The edge is etched with an etchant to reduce the size and number of flaws on the edge, thereby strengthening the edge. A glass article having an edge strengthened by the method is also provided.
