Abstract
The present disclosure relates to an enamel composition, a method for preparation thereof, and a cooking appliance using the same, which provide excellent cleaning performance, reduce a defect caused by carbon gases when an enamel coating is implemented on a base material made of cast iron, and provides excellent thermal shock resistance and durability. In the enamel composition according to the disclosure, components implementing glass and components having catalytic performance have an optimal component system, thereby ensuring excellent thermal shock resistance and durability. The enamel composition of the present disclosure has a component system that helps enamel cast iron as well as low carbon steel, thereby ensuring excellent cleaning performance, thermal shock resistance and durability. The enamel composition of the present disclosure is appropriate for a cooktop grate, a hob burner, and the like which directly contact a fire and are exposed to repetitive thermal shock.
