<p>A ceramic composite for porous ceramics and a manufacturing method of a tea bowl using the same are provided to perform a unique beauty by properly mixing a sandy soil, clay, and pink kaolin. A ceramic composite for porous ceramics includes sandy soil 60~90 weight%, clay 5~30 weight%, and pink kaolin 5~20 weight%. The composite includes SiO2 450~520 molar ratio, Fe2O3 8~10 molar ratio, K2O 15~25 molar ratio, MgO 6~10 molar ratio, CaO 2.5~3.5 molar ratio, and Na2O 1.0~3.0 molar ratio about Al2O3 100 molar ratio. A manufacturing method of a tea bowl comprises the following steps: a step for molding a vessel through a ceramic composite; a step for primarily sintering the vessel at 800~900‹C after drying the vessel; and a step for secondarily sintering the primarily sintered vessel at oxidizing flame or reducing flame of 1150~1250‹C after applying glaze to the primarily sintered vessel.</p> |
