ABSTRACT:
The present invention relates to an ultraviolet and infrared absorptive greenish glass (the first glass) containing in weight % expression at least coloring components of 0.3-0.5% of total Fe2O3, 0.8-2.0% CeO2, 0.8-2.0% TiO2, and 0.10-0.25% of FeO. This first glass may be an ultraviolet and infrared absorptive greenish glass (the second glass) in which CeO2amounts to 0.8-1.5% and TiO2amounts to 0.8-1.5%, and which contains at least 0.1-0.7% SnO as a coloring component. Each glass is characterized in each glass at 5 mm thickness is 9% or less in ultraviolet transmittance (Tuv) according to ISO/DIS9050, 1% or less in 350 nm wavelength transmittance (T350), 70% or greater in 550 nm wavelength transmittance (T550), and 25% or less in 1100 nm wavelength transmittance (T1100).
