Claim 17:
18. A cooking vessel for cooking foods, comprising:
a metal body comprising a bottom wall and at least one side wall, wherein said at least one side wall extends from said bottom wall to form an inner compartment of the cooking vessel into which food is arranged for being cooked;
a handle, constrained to a portion of the metal body by a metal fastening element;
a thermal signalling device applied to a portion of the handle arranged at a respective component having thermal conductivity properties, said thermal signalling device being provided with at least one an indicating element and with a respective actuating element made of a shape-memory alloy;
a metal base for modulation and/or thermal enhancement, interposed between said actuating element and said component having thermal conductivity properties,
wherein the indicating element is operatively connected to the respective actuating element and is configured for highlighting that the cooking vessel has achieved a predefined thermal state through a mechanical movement of the respective actuating element, which is activated when said predefined thermal state is achieved,
wherein the respective actuating element is a shape-memory coil spring, indirectly contacting said component having thermal conductivity properties, said shape-memory coil spring being configured for switching from a first non-operative configuration of the thermal signalling device, wherein said shape-memory coil spring is inactive, to a second operative configuration of the thermal signalling device, wherein said shape-memory coil spring is stretched when a predefined temperature value is achieved, and said metal base for modulation and/or thermal enhancement is arranged in direct contact with said component having thermal conductivity properties to transfer heat to said shape-memory coil spring,
wherein the thermal signalling device is manufactured as a separate component with respect to the handle and comprises a casing containing the indicating element and the respective actuating element,
wherein said casing is applied, either fixedly or removably, to the upper back of a metal fireproof ferrule forming said component having thermal conductivity properties,
wherein said casing, when applied removably to the upper back of the metal fireproof ferrule, is provided with magnetic fastening means.
