A vitroceramic cooking surface is endowed with a artificial black decoration obtained by firing a decoration color. In order to obtain an intense and very brilliant black decoration, one applies, on a black tinted vitroceramic plate, forming a cooking surface, a decorating color that contains a flux that melts and remains uncolored on the black tinted vitroceramic and that contains a black pigment in a proportion of between 0 and 10%. L'invention concerne une surface de cuisson en vitrocéramique, dotée d'un décor simili-noir obtenu par cuisson d'une couleur à décor. Pour obtenir un décor noir intense et très brillant, on applique, sur une plaque en vitrocéramique teinte en noir dans la masse, formant une surface de cuisson, une couleur à décor qui contient un fondant qui fond en restant incolore sur la vitrocéramique teinte en noir et qui contient un pigment noir en une proportion pondérale de 0 à 10 %.
