Abstract: An enamel composition for a cooking appliance is prepared by a preparation method. The enamel composition includes glass frits, a siloxane-based compound, a silane-based compound, and mill addition. The mill addition includes one or more materials selected from a group comprised of SiO2, Al2O3, ZrO2, and TiO2, thereby suppressing defects such as chipping even when the enamel composition is used at high temperature, for pyrolysis of contaminants.

Abstract: Described is a method for controlling an induction heating device having one or more working coils and a controller configured to perform pre-testing based on a single pulse. The method includes: selecting a working coil to be tested, performing a detection operation to detect a vessel disposed on the working coil and generate a first output pulse; comparing at least one of: a count of the first output pulse to a predetermined reference count range, or an on-duty time of the first output pulse to a predetermined reference time range; and adjusting, by the controller, a duration of an on-state of the single pulse based on (i) a result of the comparison of the count of the first output pulse to the predetermined reference count range or (ii) a result of the comparison of the on-duty time of the first output pulse to the predetermined reference time range.
