Abstract

A kitchen cooktop surface in a material of nature, such as marble may be fitted with induction heating elements providing higher efficiency than mere placing in contact with the lower side of the cooktop. According to the invention the cooktop is hollowed out from the lower side, leaving only a thin partition which is reinforced by means of casting in situ of a ferromagnetic particle loaded material. Alternatively, the top surface may be penetrated, and a central circular piece of the cooktop material may be retained by means of similar casting in situ.
