MANUFACTURING METHOD OF OVERGLAZED PORCELAIN WITH PATTERNS USING LASER

摘要

The present invention relates to a method for manufacturing an over glaze decorated pottery using a laser which includes the steps of: primarily baking a molded object; glazing the first glaze onto the primarily baked resultant; secondary baking the resultant glazed with the first glaze; glazing a coloration glaze having a color different from the color of the first glaze onto the secondary baked resultant; forming a decoration by irradiating a laser onto the coloration glaze while selectively melting the coloration glaze; and removing a portion of the coloration glaze where the laser is not irradiated. According to the present invention, the design pattern can be accurately imprinted by irradiating the laser onto the surface of the glazed pottery to induce melting of the partial glaze and cleaning a region where the energy (laser) is not applied. Also, the mass production can be possible and various decorations can be expressed by incorporating a laser technique.
