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.
Claims18
A method for manufacturing a glass article comprising:
- forming the glass article, wherein the glass article comprises a first major surface, a second major surface parallel to the first major surface, and an edge surface extending between the first major surface and the second major surface in a perpendicular direction to the first and second major surfaces;
- applying an etch cream to the edge surface of the glass article, wherein application of the etch cream reduces a density of particles on the edge surface.
