摘要： A glass ceramic article is provided so that a reliable coloring with a defined transmittance is ensured. The reliable coloring of the glass ceramic article is based on a high content of iron oxide of more than 0.1 percent by weight which itself has a strongly coloring effect does not further reduce transmittance but rather interacts with vanadium oxide to attenuate the absorption caused by vanadium oxide.
