A system is provided for heating by induction in a receptacle (17) of non-ferrous materials such as aluminum, PFTE, earthenware and others, of an insert (18) consisting of a thin body of ferromagnetic material, such as wire gauze, which is deeply embedded in the base (21) of the receptacle (17). The base is subsequently ground and polished to render the external surface of the thin body (18) of ferromagnetic material perfectly coplanar with the material surrounding it.

1. System for induction heating and cooking of bodies in general, especially food, in a receptacle by application, in a die, to a base of the receptacle of an insert consisting of a thin body of ferromagnetic material, characterized in that the insert is completely enclosed by placing in a base of the die magnetic spacers that create, between the insert and an external surface of the base of the receptacle, a certain thickness even if the die is placed vertically. 2. System as in claim 1, wherein the die is suitable for a casting process in non-ferrous metal, wherein said non-ferrous metal is selected from the group consisting of aluminum, nickel, cobalt, copper and their alloys. 3. System as in claim 1, wherein the receptacle is made of tetrafluoroethylene polymer (PTFE). 4. System as in claim 1, wherein the insert is a piece of gauze. 5. System as in claim 4, wherein the gauze is of the type known as stretched. 6. System as in claim 1, wherein the insert is a perforated sheet having perforations spaced closely to one another. 7. System as in claim 6, wherein the perforations are round. 8. System as in claim 6, wherein the perforations are square. 9. System as in claim 1, wherein the base of the receptacle is ground and polished to render an external surface of the insert perfectly coplanar with material surrounding it. 10. System as in claim 1, wherein the receptacle is made of earthenware. 11. System as in claim 1, wherein the receptacle is made of glass. 12. System as in claim 1, wherein the insert is incorporated by casting in an aluminum base applied to a steel cooking pan.
