DECORATED GLASS-CERAMIC PLATE AND CORRESPONDING METHOD OF DECORATION

摘要

The invention relates to a decorated glass-ceramic plate, suitable in particular as a cooktop, comprising a glass-ceramic plate having a low coefficient of thermal expansion between +/- 15 x 10<-7> K<-1> (20-700 DEG C) and a decoration on the surface of said plate. Characteristically, said decoration comprises a vitrified glass frit containing 10 to 35 % by weight of pigments and said decorated glass-ceramic cooktop has a modulus of rupture of at least 120 MPa. The invention also relates to a method of decorating glass-ceramic plates and to an enamel which is useful in particular for implementing said method.
