Abstract: A method of manufacturing a glass article includes application of an etch cream to an edge surface of the article. Application of the etch cream can reduce a density of particles on the edge surface to less than about 200 per 0.1 square millimeter. The etch cream can, for example, contain hydrofluoric acid, hydrochloric acid and a thickener.
