Abstract
A textured glass article includes: a body comprising an aluminosilicate glass comprising greater than or equal to 16 wt % Al2O3 and a Al2O3/SiO2 ratio less than or equal to 0.3, the body having at least a first surface; a plurality of polyhedral surface features extending from the first surface, each of the plurality of polyhedral surface features comprising a base on the first surface, a plurality of facets extending from the first surface, and a surface feature size at the base greater than or equal to 10 μm and less than or equal to 100 μm, wherein the plurality of facets of each polyhedral surface feature converge toward one another; and a transmittance haze greater than or equal to 50%.
