Flat glass is disclosed, bearing a tin oxide coating layer which is at least 200 nm in thickness. In order to promote a uniform visual appearance across the coated area, the expected grain area of a representative sample of the tin oxide coating crystals measured in units of 10-4 mu m2 is numerically equal to a value of at least 0.4 times the layer thickness measured in nanometers. |
