Abstract

The invention belongs to the field of porcelain product and relates to Dehua pearl white porcelain and a preparation technology thereof. The prepared Dehua pearl white porcelain comprises a pearl white porcelain body and pearl white glaze. The glaze surface of the prepared Dehua pearl white porcelain has milk white pearly luster, and has the artistic effect closest to that of traditional Dehua pearl white porcelain. Through detection of the glaze surface of the prepared Dehua pearl white porcelain, the refractive index of the surface of the pearl white porcelain is 1.4-1.5, the glaze surface is capable of reflecting light energy into milk white light, the light is abundant, changeable and not dull, and delicate changeable iridescence can be seen through angle transformation; the glaze surface of the Dehua pearl white porcelain is relatively thick, so that the pearl glossiness of the glaze surface can be more obvious and the thick feeling of the porcelain body can be increased; and in addition, the pearl white porcelain has good shielding property on the body and is capable of properly reducing the quality and the content of kaolin in the raw materials of the body, and the kaolin is replaced with low-price bentonite, so that the production cost is reduced.

Description
