Abstract: Embodiments relate to a glass composition which can allow for realizing beautiful bluish green colors therein even upon the use of a trace amount of a colorant such as Ti, Co, and Cr, securing high visible light transmittance suitable for window glass, and effectively reducing transmittance of solar heat radiation to help reduce a cooling load in buildings and vehicles.

Abstract: Embodiments relate to a green glass composition, which can reduce the cooling load of a building and a vehicle by effectively lowering solar heat ray and ultraviolet ray transmittance while ensuring a high visible light transmittance suitable for window glass without using a coloring agent such as Ce, Co and Cr, and also has excellent bubble quality; green glass manufactured therefrom; and a method for manufacturing green glass. According to at least one embodiment, there is provided a green glass composition including 0.65-1.3 wt % of Fe2O3, 0.1-0.4 wt % of TiO2, and 0.05-0.20 wt % of SO3, based on 100 wt % of a soda lime mother glass composition, wherein an oxidation-reduction ratio of Fe2O3 is 0.22 to 0.38.
