(57) [Summary] [Constitution] 0.53 to 0.70 of total iron converted to Fe 2 O 3 in the weight percentage of soda-lime-silica base glass. %, Fe 2 O 3 0.35~0.50% , FeO0.16 ~0.24%, TiO 2 0.2~0.4%, CeO 2 F containing 0.5 to 0.8% and converted to Fe 2 O 3 The weight of eO is 30 to the weight of total iron converted to Fe 2 O 3. A glass having a small solar radiation transmittance and an ultraviolet transmittance of 40%. [Effect] The material can be changed in a short time, the productivity is high, and the clarification is easy. |
