GLASS SHEET APPROACHING ITS CHARACTERISTICS TO NEUTRAL INDEPENDENT OF THICKNESS

摘要

The present invention relates to sheet glass, the composition of which contains the total mass fraction of iron in percent, expressed as FeO and equal to 0.002-0.03% in terms of the total weight of glass and is characterized by the following: a and bmeasured for a sheet 5 mm thick when passing the illumination D65, 10 °, SCI; a and b are calculated for a 0 mm thick sheet by passing the illumination of D65, 10 °, SCI. Such a sheet of glass makes it possible to obtain a specified sheet with such a color rendition, which remains essentially the same for any viewing path available looking at an object of which the specified sheet of glass is a part (if you look through its main surfaces, or through edges, or through an area with a diffusing coating ).
