Abstract: Disclosed in the present application include: (i) plates, having two approximately parallel main sides, of a glass-ceramic or a glass displaying a certain transparency, with a colored coating fixed to at least one part of the surface of one of said two main sides; (ii) heating plates, particularly cook-tops, consisting of such plates or obtainable from such plates. These heating plates are intended to be fitted above heating elements, their side bearing said coating facing said heating elements; and (iii) the preparation of such plates. The original colored coating proposed is particularly interesting with reference to its color stability.

Abstract: Disclosed in the present application include: (i) a method of reinforcing plates, having two approximately parallel main sides, of a glass-ceramic or a glass, said method comprising fixing at least one layer comprising at least one (co)polymer which is resistant to high temperature onto at least one part of the surface of at least one of their two main sides; as well as (ii) reinforced plates of this type.
