Abstract

The invention relates to a manufacturing method using reducing atmosphere to fire scattering-blue glaze. The ground glaze of the scattering-blue glaze comprises, by weight percentage, 5-15% of Dicranopteris linearis ash, 25-40% of Yaoli glaze stone, 2-5% of Zhuming material, 1-3% of tin oxide, 5-10% of copper scale and 30-60% of saltpeter frit. The surface glaze of the scattering-blue glaze comprises, by weight percentage, 30-40% of Yaoli glaze stone, 15-30% of Shouan lime-flyash and 30-55% of saltpeter frit. The manufacturing method includes: preparing raw materials, performing ball milling, sieving, performing unique twice glaze application on a high-temperature biscuit-firing body, and firing the scattering-blue glaze under the reducing atmosphere of 1100-1200 DEG C. The method has the advantages that the manufactured scattering-blue glaze is even in blue spot scattering, stable in appearance color, good in decoration effect and promising in application prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a blue glaze and an application method thereof. Background technique [0002] Sprinkle blue glaze, also known as "snowflake blue glaze", was created and fired in Jingdezhen during the Xuande period of the Ming Dynasty, and then stopped firing. It was not until the Kangxi period of the Qing Dynasty that production resumed. The blue-glazed porcelain from the Kangxi, Yongzheng, and Qianlong periods of the Qing Dynasty was stable in color and fine in workmanship. Its characteristic is that the glaze layer is thicker in the dense part, and the white ground is exposed in the thin part, making the glazed surface seem to be covered with a layer of snowflakes, and the color is bright and elegant. Due to the complicated firing process and low success rate, blue-glazed porcelain was a relatively rare variety at that time. In the late Qing Dynasty, th...
