PROBLEM TO BE SOLVED: To develop a color tone of glass which looks like a dark greenish tone of an imported glass and is easy to recycle, by an oxidizing glass.;SOLUTION: This color tone of glass is realized by a soda-lime glass which contains 0.09-0.13% of Fe2O3, 0.15-0.17% of Cr2O3, 0.01-0.04% of MnO, and 0.02-0.04% of CuO as a colorant, and 0.15-0.24% of SO3. This color tone of glass is a dark green color of which the lightness Y is 30-60% in CIE expression (in terms of 3 mm thickness), the main wavelength λd is 540-580 nm, and the excitation purity Pe is 10-50%.;COPYRIGHT: (C)2006,JPO&NCIPI
