<p>The invention relates to a glass sheet, one of the sides of which comprises a frosted surface, wherein the texture of said frosted surface is defined by: (i) a value Ra greater than 1.5 mum and less than 4 mum; and (ii) a value RSm greater than 40 mum and less than 250 mum as measured over an evaluation length of 12 mm and using a Gaussian filter, the cutoff wavelength of which is 0.8 mm. The invention particularly relates to such a glass sheet including, on at least 50% of the frosted surface, a plurality of polyhedra, each polyhedron including a base that lies within the plane of the sheet and at least one planar polygonal side. Such a glass sheet is translucent, diffusive, and has a bright, iridescent appearance.</p> |
