Abstract: A low reflectance glass surface is disclosed which includes a particular combination of surface structures which produce a low reflectance yet high clarity glass. The surface structure includes a plurality of islands distributed at a density of about 60 to 10,000 islands per square millimeter. The glass surface also includes a skeletalized silica structure of 200 to 600 angstroms in diameter, uniformly distributed over the surface. By combining the various surface structures on one piece of glass, unique properties of low reflectance yet high clarity are provided, which is particularly suitable for use in picture frames where any distortion would distract from viewing a picture contained therein and also in computer or t.v. screens where distortion or glare could produce operator fatigue or stress. The glass structure is achieved by a process which is readily adaptable to existing production lines without requiring major modifications.

Abstract: A low reflectance glass surface is disclosed which includes a particular combination of surface structures which produce a low reflectance yet high clarity glass. The surface structure includes a plurality of randomly distributed surface scallops which have a diameter of about 100 to 2000 micrometers, with a plurality of islands at spaced-apart intervals distributed thereover, at a density of about 25 to 500 islands per square millimeter. The glass surface preferably also includes a microporous structure which is uniformly provided across the surface of both the scallops and the islands, with the micropores being about 0.2 to 1.0 micrometers in diameter. The glass further includes a skeletalized silica structure of 200 to 600 angstroms in diameter, uniformly distributed over the surface.
