PURPOSE: A composite for a Buncheong ceramic ware capable of injection-molding is provided to be able to mass-produce various types of Buncheong ceramic wares by controlling the viscosity of the composite and the content of micro-powder. CONSTITUTION: A composite for a Buncheong ceramic ware capable of injection molding comprises 8-18 weight% of feldspar, 18-28 weight% of pottery stone, 22-32 weight% of kaolin, 8-18 weight% of silicastone, 8-18 weight% of clay, and 15-28 weight% of pottery soil. The viscosity of the composite for the Buncheong ceramic ware is 700-3,000cp. The micro-powder content with the particle diameter of 2um or less contained in the composite is less than 20 weight%. The slip specific gravity of the composite is 1.7-1.75g/ml. A manufacturing method of the Buncheong ceramic ware comprises the following steps: feldspar, pottery stone, kaolin, and silica stones are firstly pulverized; clay and pottery soil are mixed with the firstly pulverized material, and secondly pulverized; the composite for the Buncheong ceramic ware is formed with the secondly pulverized material; the composite is injected and molded in a mold with a desired shape; and the inject-molded material is plasticized.
