Abstract
For removing halo formation, which often occurs on glass-ceramic articles decorated with a ceramic color, a layer of SiO.sub.2 is applied to the glass-ceramic article after the glass-ceramic color has been burnt-in. The layer is preferably 40-200 nm thick. The layer can contain up to 66.5% by weight of oxides, which change the refractive index so that the layer is invisible, the layer being, for example, 85-93% by weight of SiO.sub.2 and 7-15% by weight of TiO.sub.2.
