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: A glass plate according to the present disclosure includes: a coated area and an uncoated area; a heating layer that is coated on the coated area and includes a conductive material generating heat by receiving power; and two bus bars that extend along an extension direction, that are electrically connected to the heating layer to supply the power to the heating layer, and that are spaced apart from each other along a reference direction orthogonal to the extension direction. The uncoated area includes a plurality of uncoated lines having a length along the reference direction and formed as a single line bent at least once. The plurality of uncoated lines is disposed to be spaced apart along the extension direction.

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.
