A laminate includes at least two sheets, one of the at least two sheets including a colored glass and another of the at least two sheets being a further sheet. The sheet including the colored glass in a wavelength range from 875 nm to 1600 nm has an internal transmittance at at least one wavelength of at least 75%. A connecting layer is disposed between the at least two sheets. The laminate has a thickness of at most 6 mm. The laminate in a wavelength range from 400 to 700 nm has an average transmittance τof less than 15% where τis defined as and/or at each wavelength has a spectral transmittance of less than 15%.

Laminated glass and its use

A glass includes: a plurality of components (in wt.-%) as follows: a sum of a plurality of proportions of LiO, NaO and KO being in a range of from 5.0 to 30.0 wt.-%, a sum of a plurality of amounts of MnOand CrObeing at least 0.3 wt.-%, and a ratio of a plurality of proportions of MnO(in wt.-%) and CrO(in wt.-%) being in a range of from 1.5:1 to 12.5:1.
