One name for this type of kiln is Yikun. It was made by Ou Zi Ming of Yixing during the Ming dynasty in China, and is called Yiqun because most of its form follows that of the Yiqun kilns. It is a different lineage from the Yang Jiang Meimei pottery produced in Yixing, i.e., the Zhu Dao school.
It is also somewhat different from the Qing dynasty’s purple sand glaze (glazed purple mud). Most of them seem to have been mixed with a little bit of porcelain during production and are not made of pure purple sand. There are also bottles and pyramids, but the most common type is said to be washing. Although both the Ou and Guang kilns have a massive appearance and are very similar in shape, they are not actually the same. The most common difference between the two types of wares is that the Kwang ware has the largest number of indigo spots in the blue, and although there are other colors, they all do not produce the same type of glaze, namely, grayish black. The Ou ware has a slightly greater range of colors, with the exception of cyan blue, and a deep purple color similar to that of the HUN kiln, as well as cloud bean and eggplant peel, and the indigo spots are not as dark as in the Huang ware.
This is one of the differences between them. The bottom of the Guang kiln has many exposed bodies, while the bottom of the Ou kiln has very few exposed bodies. The Guang ware is pure and elegant, and the Ou ware is elegant and elegant, but has a beautiful and elegant appearance, which is the third difference between the two. In the Qing dynasty, Tang Ying imitated the Ou ware in Jingdezhen, but while the Ming Ou ware has a tachibana bark glaze, Tang Ying’s imitation does not, and the glaze is also not different from that of Qianlong (1736-95) wares. It is easy to tell at a glance which is Ming and which is Qing. (Yunryusai sesshu)
