Abstract
The invention relates to glass sheet having a composition comprising the following in weight percentage, expressed with respect to the total weight of glass: Total iron (expressed in the form of Fe2O3) 0.002-0.15% Selenium (expressed in the form of Se) 0.0003-0.005% Cobalt (expressed in the form of Co) 0.00005-0.0015%; the glass sheet being characterized in that: N≤10.3*Fe2O3+0.11; N being defined as Formula (I). Such a glass sheet has a high luminous transmittance and has colorless/achromatic edges (very neutral in color). This invention is particularly suitable due to its aesthetics as building glass or interior glass, like for example in furniture applications.
