Abstract: A coating composition, a coating glass, a method for preparing a coating composition, and cooking appliances using a coating composition. More specifically, the coating composition may include 20 to 40% by weight of Phosphorus Pentoxide (P2O5), 10 to 25% by weight of 10 to 25% by weight of Aluminum Oxide (Al2O3), 1 to 5% by weight of Zirconium Dioxide (ZrO2), 10 to 30% by weight of at least one of Sodium Oxide (Na2O) and Potassium Oxide (K2O), 5 to 20% by weight of Boric Oxide (B2O3), 5 to 15% by weight of Zinc Oxide (ZnO), and 3 to 10% by weight of Silicon Dioxide (SiO2). Thus, the coating composition has high light transmittance, and excellent cleaning performance.
