Glass sheet having a high IR and visible transmission with a pleasing slight colour to neutral colour

摘要

A glass sheet having a composition which comprises total iron (expressed in terms of Fe2O3) from 0.002-0.06 wt %; chromium (expressed as Cr2O3) from 3-75 ppm; and manganese (expressed as MnO) from 50-1,000 ppm. The glass sheet has a LTD4 higher than 70%. Such a glass sheet exhibits at once a high luminous transmission, an increased transmission of infrared (IR) radiation and a pleasing slight color or an almost neutral to neutral color.
