Abstract

The invention belongs to the field of porcelain products, and particularly relates to Te-hua scallion-root-white porcelain and a preparation method thereof. A whiteness degree of the prepared Te-hua scallion-root-white porcelain is between 83 and 85 degrees, a water absorption rate is 0, the light transmittance is greater than 15 percent (1 mm), the Te-hua scallion-root-white porcelain is white and pure, and a glaze surface is moisturized. According to the Te-hua scallion-root-white porcelain, local raw materials of Te-hua are selected as raw materials for burning the scallion-root-white porcelain, chemical components of the raw materials are strictly controlled, rose quartz are introduced into the raw materials of a green body and glaze, so that not only can the content of silicon dioxide in the raw materials be increased, but also natural and trace Mn and Ti of the rose crystals can improve the moisturizing degree of the green body and the glaze surface, the color is moisturized, the glaze surface is soft, and an artistic effect closest to traditional Te-hua scallion-root-white porcelain can be achieved.
