<p>An ultraviolet and infrared absorptive greenish glass (a first glass) which comprises, in wt %, 0.3 to 0.5 % of total Fe2O3, 0.8 to 2.0 % of CeO2, 0.8 to 2.0 % of TiO2, and 0.10 to 0.25 % of FeO, as coloring components; and an ultraviolet and infrared absorptive greenish glass (a second glass) which is the first glass wherein the content of CeO2 is changed to 0.8 to 1.5 %, the content of TiO2 is changed to 0.8 to 1.5 %, and 0.1 to 0.7 % of SnO is at least comprised additionally as a coloring component. Each glass is characterized in that it exhibits an ultraviolet transmittance (TUV) according to ISO/DIS9050 of 9 % or less, a 350 nm wave length transmittance (T350) of 1 % or less, a 550 nm wave length transmittance (T550) of 70 % or more and a 1100 nm wave length transmittance (T1100) of 25 % or less.</p> |
