defined temperature program the cut out molded parts are annealed at temperatures up to 1600 u00b0 c and subsequently slowly cooled this has the result that the ceramic material does not crack and or does not later deform in an undesired way under thermocyclic conditions as are provided in a cooktop 3 this temperature treatment step is preferably combined with the baking of the printed resistor web 23 in addition it is preferable according to the present invention to apply a glass or glass ceramic layer over the resistor web 23 to protect and possibly insulate the latter the application is again performed using screen printing technology this protective insulating insulation layer 26 is subsequently fixed on the substrate carrying the resistor web 23 through baking at or just below the melting temperature of the glass or ceramic frit used electrical contact between the contact 41 and the resistor web 23 may be produced via a metal strip 42 which is connected to the resistor web 23 from the contact 41 via a slot in the ceramic element 22 see fig1 an elastic contact 41 a may also be connected via a rivet 43 to the ceramic element 22 the resistor web 23 being clamped between the elastic contact 41 a and the ceramic element 22 fig2 shows a ceramic cooktop 33 having heating regions 3 the number shape and position of the heating regions 3 on a cooktop may be varied arbitrarily in.
