GLASS SHEET HAVING A HIGH IR AND VISIBLE TRANSMISSION WITH A PLEASING SLIGHT COLOUR TO NEUTRAL COLOUR

摘要

The invention relates to a glass sheet having a composition which comprises: - total iron (expressed in terms of Fe 2 O 3 ) : 0.002 - 0.06 wt% - chromium (expressed as Cr 2 O 3 ): 3 - 75 ppm - manganese (expressed as MnO): 50 - 1000 ppm, and having a LTD4 higher than 70%. Such a glass sheet exhibits a high luminous transmission, an increased transmission of infrared (IR) radiation and a pleasing slight color or an almost neutral to neutral color.
