Abstract: A method for manufacturing ceramic boards for use as finishing construction materials is provided, which includes the steps of: blending raw materials at predetermined ratios; mixing the blended raw materials with water to prepare a mixture; kneading the mixture to remove bubbles; molding the bubble-free kneaded mixture into planar wares having a face; engraving a predetermined pattern on the face of the planar wares and then filling the patterns with a colored inlay material to form inlaid surfaces; drying the engraved and inlaid wares; polishing the inlaid surfaces to expose the patterns; primarily calcining the wares having exposed patterns at a temperature of 800° C. to 900° C. for a predetermined period to prepare primary ceramic boards; coating a glaze mixture composed of components at fixed ratios on the faces having the exposed patterns to prepare glazed wares and then drying; and secondary calcining the glazed wares at a temperature of 1250° C. to 1350° C. for a predetermined period.
