Ru porcelain is the first of five famous porcelain, and the traditional Ru porcelain is mainly prepared by adding quartz, black feldspar, yellow feldspar, high collar soil (Fengcave soil and half slope soil), clay (black hair soil and Tanggou soil), calcite, dolomite, plant ash and the like; when adding, the method mainly comprises the following steps of: processing the raw materials into pug and glaze by the traditional process, and performing the working procedures of picking, rinsing, crushing, grinding, ageing and the like; and then molding: manually drawing, carving, kneading and rubbing the blank for molding; and (3) final firing: biscuit firing at about 800 ℃, glazing by a glaze dipping method, glazing for 1 or 2 times according to the color requirement of a product, and firing by reducing fire. Although iron ore is added in the preparation of the outer glaze in the patent application of CN102503365A, the amount of the added iron ore is small, the weight percentage of the added iron ore is only 2-3%, particularly, tourmaline powder without nano-scale particles is not added in the patent, and the nano-scale tourmaline has a good piezoelectric effect. In the patent application CN101700167A, although it is mentioned that the ru porcelain bowl has the function of keeping fresh, the component capable of forming the function of keeping fresh in the porcelain material is added with green agate, because the technical solution of the application lacks the substance with piezoelectric magnetic substance and the effective combination of various magnetic substances, the application does not use iron ore and silica, so the application does not have the function of magnetization and health care effect. Therefore, the preparation method and the ingredients of the porcelain are single, and the prepared porcelain has no good effect.
