Academics call the Yaozhou kiln in the Tang and Five Dynasties period "Huangbao kiln", and the kiln site in the Song Dynasty and later is called Yaozhou kiln. The tea glaze applied to the pot belongs to the iron crystal glaze fired by high-temperature reduction flame, which is one of the innovative color glaze varieties of Huangbao kiln in the Tang Dynasty, which is a crystallization produced by the combination of iron, magnesium and silicic acid in the glaze. Its glaze is milky, moist and shiny, but has a sense of opacity. The glaze color has brownish green, yellow-green, emerald green, dark green, and there are often small crystalline glaze spots of dark color on the pure green bottom glaze, just like the tea powder sprayed on the surface of the vessel in the new year, so it is called "tea glaze". The representative products are nearly half a meter high giant flare mouth thin neck oval belly cake foot amphora bottle, bell mouth short flow injection pot and lip deep belly injection bowl, Islamic style skimming open flow single handle pot and so on. Although the Yaozhou kiln also fired a small amount of tea-glazed porcelain in the later sections, the quality was obviously inferior to that of the Tang Dynasty. The glaze color of the Jin, Yuan and Ming dynasties is mostly yellow-green, and the crystalline glaze spots in the form of dots are rarely seen. Compared with the products of the early Tang Dynasty of this kiln, it shows obvious characteristics of decline.
The tea glaze fired by Jingdezhen Imperial Kiln Factory in the Ming Dynasty is called "eel yellow", and the tea glaze burned by the Imperial Kiln Factory in the Qing Dynasty (especially in the Yongzheng period) is called "factory official glaze", the most successful firing in the Qianlong period, is regarded as the precious color glaze variety fired by the Qing official kiln, and the higher quality of the tea glaze in the Tang Dynasty of the Huangbao kiln can be completely comparable to it.
