Genstand af glaskeramisk materiale, især glaskeramisk plade, dekoreret med keramisk farve samt fremgangsmåde til fjernelse af haloisering fra glaskeramiske genstande dekoreret med keramisk farve

摘要

For removing halo formation, which often occurs on glass-ceramic articles decorated with a ceramic color, a layer of SiO2 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 SiO2 and 7-15% by weight of TiO2.
