Patent ID: 11214507

Abstract:
A glass sheet having a composition comprising a total iron content of 0.002-0.03% expressed in the form of Fe2O3 and in weight percentage with respect to the total weight of glass, and further satisfying the formula N*5≤0.05; N*5 being defined as N*5=√{square root over ((a*5−a*0)2+(b*5−b*0)2)}, a*5 and b*5 being measured for a sheet thickness of 5 mm in transmission with illuminant D65, 10°, SCI; a*0 and b*0 being computed for a sheet thickness of 0 mm in transmission with illuminant D65, 10°, SCI. Such a glass sheet allows a color rendering of the sheet which is essentially the same whatever the view path available for an observer of the object integrating said glass sheet (when looking through its main faces or through its edges or through a zone bearing a diffusing coating).
