<p>A soda-lime-silica glass having, at a thickness in the range of 3 mm to 10 mm, 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> |
