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.
