<p>The invention relates to an object made of hollow glass and having, for a thickness of 5 mm, a global light transmission higher than or equal to 70%, said global light transmission being calculated by taking into account the illuminant C as defined by standard ISO/CIE 10526 and the colorimetric reference observer C. I. E. 1931 as defined by standard ISO/CIE 10527, and a filtration power higher than or equal to 65% and preferably 70%, said filtration power being defined as equal to a value of 100% minus the arithmetic average of transmission of 330 to 450 nm, wherein said object has a silico-sodo-calcic chemical composition that comprises the following optical absorbing agents in a concentration that varies within the following weight limits: Fe2O3 (total iron) 0.01 to 0.15% TiO2 0.5 to 3% Sulphides (S<sup>2-</sup>) 0.0010 to 0.0050%.</p> |
