    • A ceramic ware for a kimchi refrigerator is provided to age kimchi as naturally as earthenwares, to preserve inherent taste of fresh kimchi, to contain no harmful material, and to emit no environmental hormone. A method for manufacturing a square ceramic ware for a kimchi refrigerator includes the steps of: mixing 28-32wt% of kaolin with 68-72wt% of water; putting the mixture into a lid mold and a body mold, and hardening the mixture for 30-40 minutes; removing water from the molds after hardening, and drying the molded materials naturally for 90 minutes; detaching the dried materials from the molds, and drying the molded materials in the shade for 2-3 days; coloring the molded materials; coating the colored materials with a glaze, and drying the glazed materials; firing the colored and glazed materials in a gas furnace at 1350 °C or below for 26-28 hours to obtain a square body and a square lid; putting a U type silicone band into the formed ceramic lid; and attaching a rubber prop to the bottom of the ceramic body. Further, limestones are adhered to inner wall surfaces of the molds.
