摘要:
In order to provide a decorative coating (9) which exhibits improved temperature resistance and strength on glass and glass-ceramic and which also has no strength-reducing effect on the substrate (3), or at least no longer has any substantially strength-reducing effect on the substrate, the invention envisions a process for producing glass or glass-ceramic articles having a decorative layer in which at least one decorative pigment (13) is mixed with a sol-gel binder (11), and the pigment mixed with the sol-gel binder is cured on the glass or glass-ceramic substrate of the article by annealing, to form a decorative layer having a porous ceramiclike structure.
