Glass

A wavelength-selective transmissive glass, comprising, as represented by mass % based on oxides,

• a total iron content represented by Fe2O3 of from 0.04 to 0.15%, from 0.35 to 0.45% of CeO2, from 0 to 0.2% of TiO2, and from 0 to 0.2% of SnO2, wherein CeO2+3×TiO2+6×SnO2 is from 0.41 to 0.5, and a value of Fe-Redox is from 25 to 65%,
• wherein a glass matrix composition comprises from 60 to 80%, of SiO2, from 0 to 7%, of Al2O3, from 0 to 10% of MgO, from 4 to 20% of CaO, from 7 to 20% of Na2O, from 0 to 10% of K2O, and 0.5% or less of B2O3,
• having a light transmittance Tmore than 315 nm and 400 nm or less at a wavelength of from more than 315 nm to 400 nm represented by the following formula of 1% or more in terms of a plate thickness of 6 mm and a light transmittance T315 nm or less at a wavelength of 315 nm or less represented by the following formula of 60% or less in terms of a plate thickness of 6 mm:
• Tmore than 315 nm and 400 nm or less=(Σk=more than 315400Ak×Tk)/(Σk=more than 315400Ak)
• T315 nm or less=(Σk=300315Ak×Tk)/(Σk=300315Ak),
• wherein Ak is a weighting factor at a wavelength k in nm for calculating T which is light transmittance defined in ISO-9050:2003, and Tk is a transmittance at the wavelength k in nm in terms of a plate thickness of 6 mm, and
• having a dominant wavelength Dw measured using light source A of 460 to 510 nm in terms of a plate thickness of 6 mm.
