Glass or glass ceramic substrates are provided that have a decorative coating. Methods for coating a glass or glass ceramic substrate with a decorative coating are also provided. In the method, a first, textured layer is applied which is filled with a further layer, so that a layer material of graded composition is formed.

Glass or glass ceramic substrate provided with a decorative coating and method for producing same

A glass or glass ceramic article is provided that has a glass or glass ceramic substrate with a decorative coating. The decorative coating includes a decoration layer and a sealing layer. The decoration layer is applied to at least some surface portions of the glass or glass ceramic substrate, and the sealing layer is applied to at least portions of the decoration layer. The decoration layer is a cured sol-gel coating having inorganic solid particles, and the sealing layer is a cured silicone coating comprising inorganic solid particles. Methods for producing such glass or glass ceramic articles are also provided.

The glass ceramic or glass element that can be subjected to high thermal loads is decorated with a metallic colorant. The metallic colorant consists of a melted silicate and at least one effect pigment, which is included in a specified proportion in a melt of the silicate glass to form the metallic colorant. The at least one effect pigment is in the form of platelets of synthetic aluminum oxide (AlO) coated with at least one metal oxide. Preferably the at least one effect pigment is a XIRALLIC&#xae; high chroma sparkle pigment supplied commercially by Merck and the metallic colorant has a pigment content of from 1 to 30 wt. %.
