摘要:
The present invention provides a glass article using a glass composition including a base glass composition and colorants. The base glass composition includes, expressed in mass %: 65 to 80% of SiO2; 0 to 5% of Al2O3; 0 to 10% of MgO; 0 to 15% of CaO; 5 to 15% of MgO+CaO; 10 to 18% of Na2O; 0 to 5% of K2O; 10 to 20% of Na2O+K2O; and 0 to 5% of B2O3, and the colorants consist essentially of, expressed in mass %: 0.6% to 1.0% of T-Fe2O3; 0.026 to 0.8% of TiO2; 0 to 2.0% of CeO2; 0.01 to 0.03% of CoO; 0 to 0.0008% of Se; and 0.06 to 0.20% of NiO. The glass article has a grayish color tone, and has a visible light transmittance in a range of 15% to 40%, which is measured with the illuminant A at a thickness of 3.1 mm.
