<p>A soda-lime-silica glass having, at a thickness in the range of 3mm to 10mm, a visible light transmittance of 35 % to 75 %, a total solar radiation transmittance in the range of 20 % to 60 %, an ultraviolet radiation transmission less than 55 %, and a blue color defined by the "CIELAB" system of L = 65 to 90, a* = -15 to -4, and b* = -15 to -2. The soda-lime-silica glass composition includes the essential ingredients of about 0.5 % to about 0.9 % weight percent total iron (as Fe2O3), about 50 ppm to 100 ppm CoO, and about 0.1 to about 2.0 weight percent TiO2, with a ferrous iron to total iron ratio of about 20 % to about 40 %.</p> |
