MANUFACTURING METHOD OF ARTIFICIAL JEWELRY AND ARTIFICIAL JEWELRY MANUFACTURED BY THE METHOD

摘要

PURPOSE: A manufacturing method of artificial jewelry and an artificial jewelry manufactured by the method are provided to enhance heat resistance of the manufactured artificial jewelry by completely removing bubbles contained in molten products. CONSTITUTION: A manufacturing method of artificial jewelry comprises the following steps: mixing materials for the artificial jewelry which includes scoria with glass crucible(110); heating the glass crucible at 1300-1500 deg. Celsius for 815 hours and primary melting the material for the artificial jewelry(120); quick cooling the primary molten material with cooling water(130); re-melting the material for the artificial jewelry by heating the cooled material in the glass crucible at 1300-1500 deg. Celsius for 815 hours(140); molding the re-molten material by using a mold(150); heat treating the molded product at 400-600 deg. Celsius for 10-16 hours and slowly cooling the heat treated molded products(160); and processing the surface of the sintered molded products(170).
