Patent ID: 8771532

Claim:
A method of making a glass article having an anti-glare surface, the method comprising the steps of: a. providing a glass article; b. growing crystals on a surface of the glass article; c. etching glass from the surface surrounding the crystals with a first etching solution to form a roughened texture on the surface; d. removing the crystals from the surface by applying a second aqueous etching solution to the surface, wherein the second aqueous etching solution comprises a mineral acid and is free of HF, to form the anti-glare surface; and e. etching the surface after removing the crystals to obtain at least one of a selected surface roughness, a selected surface haze, and a selected distinctness-of-reflected image, wherein the step of etching the surface after removing the crystals comprises applying an aqueous etching solution comprising a mineral base and a chelating agent to the surface.
