The present invention relates to a method for manufacturing a crack-free heat resistant ceramic pot. The crack-free heat resistant ceramic pot is manufactured by molding an object by a molding method such as a pottery wheel shaping method, a frame molding method, and a casting method by using a heat resistant ceramic composition, firing the molded object, coating the surface of the fired object with a ceramic coating agent, and treating the object with heat. According to the present invention, food dose not stick to the crack-free heat resistant ceramic pot during a cooking process and the crack-free heat resistant ceramic pot can be washed in an easy manner as there is no crack on the surface coating layer of the heat resistant ceramic pot. Pores and surface protrusions are formed on the heat resistant ceramic pot during a manufacturing process. Therefore, an additional sand blast procedure does not need to be performed for ceramic coating. The coating layer is not separated for damaged even after use for a long time as adhesive force between the surface and the coating layer of the heat resistant ceramic pot is excellent. |
