Abstract

The invention relates to articles comprising a metal surface provided with a glass-, glass-ceramic- or ceramic-type protective layer, characterized in that the protective layer comprises a base layer comprising a matrix made of an alkali and/or alkaline earth silicate and an alkali metal- and alkaline earth metal-free top layer comprising a matrix made of an oxidic silicon compound, and to a method for the manufacture of said articles.The articles comprising the protective layer exhibit high chemical resistance and improved non-stick properties. They are characterized in particular by high dishwasher resistance.
