The present invention relates to a glass composition, and a method for producing same, where the glass is a soda-lime-silica glass, and comprises, in weight percentage: from 1.30 to 2.50% of total iron expressed as Fe2O3; from 15 to 40% of Fe2+ (Ferrous) and from 0.15 to 0.65% of FeO, expressed as Fe2O3; from about 0.05 to about 0.30% of SO3; from about 0.02 to about 1.0% of TiO2; from about 0.0002 to about 0.03% of Cr2O3; and from about 0.0002 to about 0.015% of CuO. The glass having an illuminant “A” light transmission (TLA) greater than 70%, a direct solar transmittance (TDS) of less than 51%, a total UV light transmittance (TUV) of less than 40% and a total solar transmittance (TTS) of less than 63%; a dominant wavelength (λ) from 490 nm to 600; and excitation purity less than 7, for thickness from about 0.7 to 3.0 mm.
A symmetric-hybrid or asymmetric-hybrid laminated glass having an inner ply, an outer ply, and a polymer interlayer provided between the inner ply and outer ply, the inner ply and the outer ply and the polymer interlayer being laminated together, wherein the at least one ply includes at least one glass sheet comprising a glass composition comprising a soda-lime-silicate base glass and a colorant, wherein the colorant comprises 1.30 to 2.50% of total iron expressed as Fe2O3;
