Modern cooking ranges have a glass-ceramic panel ( ) providing a cooking surface with at least one cooking zone, which typically is associated with a radiating heated body. To indicate the cooking zone and, if necessary, the residual heat, it is known to associate an externally lighted annular glass with the heated body, which is observable from above as a lighted ring. A structured lighted cooking zone indicating device is provided according to the present invention by a structured light-impermeable coating layer ( ) applied directly to the underside of the glass-ceramic panel ( ) having transparent regions forming a predetermined or desired structure or pattern within the cooking zone indicating device. This cooking zone indicating device is made by a screen printing technique in which a heat-resistant light-impermeable varnish is applied to the underside of the glass-ceramic panel to form the structured coating layer ( ).
