Abstract:
1. A glass article, the glass article having a peripheral surface, the peripheral surface comprising a roughened portion that has been ground and etched, wherein the roughened portion has a RMS roughness that is capable of scattering light of a predetermined wavelength, and wherein the peripheral surface having the roughened portion has a particle release of less than about 740 particles/cm 2 area of the peripheral surface, wherein each of the particles released is greater than 2 μm in size, and wherein the light scattered by the roughened portion, when measured at an angle in a range from about 5° to about 60° to incident light, has a normalized intensity in a range from about 120 to 20 with absolute total scattering in a range from about 1% up to about 20%.
