摘要

Tinted silico-sodo-calcic glass composition contains the following coloring agents with a content varying over the given overall limits by weight: (a) Fe2O3 (total iron) : 0.01 - 0.14 %; (b) CoO : 40 - 150 ppm; (c) NiO : 200 - 700 ppm; (d) the weight ratio NiO/CoO is between 3.5 and 6; (e) the glass has a global light transmission under D65 illumination (TLD65) between 20 and 60% measured for a thickness of 6 mm.
