• a notification means capable of issuing an alert indicating that the content of said container is dangerous;
• and a control determination circuit, said method comprising the steps of:
• storing or holding the value of an output of said temperature sensor at time t1;
• starting the supply of power to said heat source at time t3 which is later than said time t1;
• terminating the supply of power to said heat source at time t4 which is after said time t3;
• storing or holding the value of an output of said temperature sensor at time t5 which is later than said time t3;
• finding the difference between the value of an output of said temperature sensor at time t1 and the value of an output of said temperature sensor at time t5;
• comparing the difference with a predetermined threshold value;
• and
• issuing an alert to said notification means depending on the result of comparison between the difference and the threshold value.
