う問題があった。In the above-mentioned prior art ultraviolet and infrared absorbing glass, the ultraviolet absorbing ability is Fe
It is provided by UV absorption due to each of 2 O 3 , CeO 2 , TiO 2 and the interaction between them. However, in a glass having a bronze color tone using the Se color, the Fe 2 O 3 content must be relatively small in order to maintain the Se pink color, and the bronze color tone is high. It was difficult to achieve both the ultraviolet absorbing ability. That is, when the content of TiO 2 is increased, yellowishness is likely to occur, and even when the content of CeO 2 is increased,
Depending on the redox balance of the glass, there is a problem that Se does not sufficiently develop color and the ultraviolet absorbing ability may not be effectively increased.
