1. A method for embodying a hotplate for a hob having at least one cooking zone that is visible when viewing the hob on a topside and upon which a preparation vessel can be positioned for preparing food, the method comprising:
providing the hotplate, wherein the hotplate is one of a glass hotplate and a ceramic hotplate;
forming at least one metallic layer and a further layer under the at least one metallic layer on an underside of the hotplate; and
after the forming the at least one metallic layer and the further layer, forming the at least one cooking zone on the hotplate by irradiating at least one region of the at least one metallic layer with a laser light of a laser beam directed to strike the topside of the hotplate and to radiate through the hotplate and moving the laser light with respect to the at least one region of the at least one metallic layer such that an entire layer thickness of the at least one region of the at least one metallic layer disposed between the hotplate and the further layer is completely continuously removed with each movement of the laser light so that the further layer is visible from the topside of the hotplate.
