Identifying elements

(1) The porcelain tire is white with a little gray in it. In the Western Jin Dynasty, the tire quality was rough and the green body was not fully sintered. During the Eastern Jin Dynasty, the quality of tires was excellent and made great progress. Porcelain tires from Tang Dynasty to Song Dynasty were gray or light gray.

(2) During the Three Kingdoms and the Jin Dynasty, the glaze was light blue with high transparency, with a small amount of bluish yellow and turquoise. During the Southern Dynasties, the glaze color was generally yellow, and the glaze was cracked, and the fetal glaze was not well combined, which was easy to peel off. In the early and middle Tang Dynasty, the glaze color was yellow or light yellow. From the late Tang Dynasty to the Song Dynasty, there was pure cyan or bluish yellow, and the fetal glaze was closely combined, and there was very little glaze shedding.

(3) Most products are the same as Yue Kiln in variety and shape, but there are some special products, such as bull-shaped lamps, brown covered cans and five-ring cans in the Eastern Jin Dynasty, while three-legged washing, carving, lion-shaped candlesticks, frog-shaped water tanks and funerary wares are rarely produced. In the Tang Dynasty, the bottom bowl had a wall-left bottom, and the abdominal wall was inclined at 45 degrees, which was higher than that of Yueyao. Yin He in the Five Dynasties and the Northern Song Dynasty tended to be broad and flat.

(4) The decoration is relatively simple, such as string pattern, lotus petal pattern and brown. Among them, brown is quite distinctive and widely used in porcelain from the Eastern Jin Dynasty to the Southern Dynasties, especially the long pattern, which is thin at first and thick at first and not seen in other porcelain kilns. In the Tang and Song Dynasties, the decorative patterns were simple, and there was no complicated carving, which was different from Yueyao in the Northern Song Dynasty.
