Colored glass-ceramic materials and colored articles made of such glass-ceramic materials

A transparent glass-ceramic, including vanadium oxide, containing a solid solution of β-quartz as a main crystal phase, comprising:

• an optical transmission, for any wavelength between 1000 and 2500 nm, of greater than 50% for a thickness of 3 mm;
• an integrated transmission Y, in the visible range between 380 and 780 nm, measured with an illuminant C, of between 1.5% and 5%, for a thickness of 3 mm;
• and
• an optical transmission, for any wavelength between 450 and 480 nm, of greater than 0.5% for a thickness of 3 mm.
