Patent ID: 11306020

Abstract:
The invention relates to a glass sheet having a luminous transmission LTD4≥87% and having a composition free of antimony and arsenic, comprising total iron (expressed in the form of Fe2O3) from 0.002-0.04% and erbium (expressed in the form of Er2O3) from 0.003-0.1%. The glass sheet composition further having a redox ratio ≤32% and satisfying the formula 1.3*Fe2O3≤Er2O3−21.87*Cr2O3−53.12*Co≤2.6*Fe2O3. Such a glass sheet has a high luminous transmittance and has warm-toned to neutral colored edges and is particularly suitable due to its aesthetics as building glass or interior glass, as well as in furniture applications, as automotive glass, or as cover glass in electronic devices/displays.
