Claim:
1. A glass article having an anti-glare surface, prepared by the process comprising: depositing deformable particles on a portion of at least one glass surface of the article comprising contacting the glass surface with a suspension of wax particles, a suspension of polymer particles, or a combination thereof; deforming the deposited deformable particles on the surface by heating to adhere the particles to the glass surface; contacting the glass surface having the adhered particles with an etchant to form the anti-glare surface, wherein contacting comprises exposing the glass surface having the adhered particles to the etchant for about 1 second to about 30 minutes; and removing the adhered particles from the glass surface, wherein the glass surface comprises at least one of a soda lime silicate glass, an alkaline earth aluminosilicate, glass, an alkali aluminosilicate, glass, an alkali borosilicate glass, a boroaluminosilicate glass, or a combination thereof, the etchant comprises at least one acid selected from HF, H the resulting glass article is a monolith or a single piece of glass; the resulting glass article has a haze of less than 30, a distinctness-of-image (DOI 20°) of 25 to 85, a surface roughness (Ra) of 50 to 500 nm, and an average roughness peak-to-valley difference profile of about 0.1 to about 10 micrometers, and the anti-glare surface comprises a distribution of topographic features having an average diameter of about 1 to about 100 micrometers.
