Dark yellow grey glass composition

The invention relates to a float glass composition, particular to a grey glass composition, and specifically provides a dark yellow grey glass composition. The dark yellow grey glass composition comprises the following functional coloring components: total iron (Fe2O3), cerium dioxide (CeO2), titanium dioxide (TiO2), chromium sesquioxide (Cr2O3), cobalt oxide (CoO) and selenium (Se). The dark yellow gray glass composition adopted by the invention has solar transmittance of 20% or below, infrared transmittance of 25% or below, visible light transmittance of 20% or below and ultraviolet transmittance of 1% or below on the basis of a glass thickness of 3.2 mm; so the dark yellow grey glass composition can meet the demand for privacy protection, has ultra-strong ultraviolet penetration blocking performance and low solar transmittance, can well prevent ultraviolet rays from damaging ornaments and people in a vehicle or in a room, and has good energy-saving and environment-friendly effects. 本发明涉及浮法玻璃组合物，特别是灰色玻璃组合物，
