1. A cooktop comprising:
a base having an upper surface and a lower surface;
an electric power supply for supplying an electrically conductive coating with electric current; and
an electrically conductive coating applied to said lower surface and operationally connected to said electric power supply;
wherein said coating consists of a paint containing electrically conductive particles, dispersed in a silicone or polyester-silicone or epoxy-silicone resin, wherein said conductive particles are selected from the group consisting of multi-wall carbon nanotubes, single-wall carbon nanotubes, graphene, copper metallic particles, nickel metallic particles, or combinations thereof;
wherein when the coating is supplied with electric current, the coating is heated by the Joule effect and the upper surface of the base is heated by conduction.
