The method for producing a glass article, the method including preparing a glass to be processed, the glass comprising a glass bulk and a low-refractive surface layer disposed on the glass bulk, and etching away the low-refractive surface layer to form an etched glass, wherein the etching away the low-refractive surface layer comprises: cleaning the low-refractive surface layer with an acid solution; and cleaning the low-refractive surface layer with a base solution after the cleaning it with the acid solution.
Abstract:
A method of detecting defects of a glass substrate includes cutting a glass mother substrate into a plurality of glass substrates, penetrating ions into an incision surface of the glass substrate to visualize defects of the incision surface, and photographing the defects of the incision surface to determine a bending strength of the glass substrate based on a size of the defects.
Abstract:
A glass substrate has a first surface, a second surface opposite to the first surface, and a thickness from the first surface to the second surface. The glass substrate includes a first region, a second region, and a third region. The first region extends from the first surface a first depth into the glass substrate and has a first compressive stress. The second region extends from the second surface a second depth into the glass substrate and has a second compressive stress different from the first compressive stress. The third region is between the first region and the second region. In the glass substrate, the first compressive stress has a maximum value at a location between the first surface and the first depth, and the second compressive stress has a maximum value at a location between the second surface and the second depth.
