Claim 0:
1. A method for heating an aerosol-forming substrate to a predefined maximum temperature, the method comprising:
providing first and second susceptor materials each in thermal proximity to the aerosol-forming substrate, wherein the first and second susceptor materials are different from each other and have different geometrical configurations than one another;
inductively heating, by activating an inductive heating device, the first susceptor material such that the first susceptor material heats the aerosol-forming substrate to form an aerosol;
detecting a first phase-change of the second susceptor material, using the inductive heating device, during the inductive heating, the first phase-change occurring at the predefined maximum temperature; and
responsive to detecting the first phase-change of the second susceptor material, stopping the inductive heating by deactivating the inductive heating device.
