Abstract: An enamel composition, a method for preparing an enamel composition, and a cooking appliance are provided. The enamel composition may include 20 to 50% by weight of silicon dioxide (SiO2), 7 to 12% by weight of boron oxide (B2O3), one or more of lithium superoxide (Li2O), sodium oxide (Na2O), or potassium oxide (K2O), and 10 to 20% by weight of sodium fluoride (NaF), 1 to 10% by weight of zinc oxide (ZnO), and one or more of molybdenum oxide (MoO3), bismuth oxide (Bi2O3), or cerium dioxide (CeO2), and 10 to 40% by weight of titanium dioxide (TiO2). With such an enamel composition, cleaning is possible in a heating condition of a relatively low temperature and without a soaking process using water.
