The Jiangyang Kiln, also known as the Jian Kiln, was a famous kiln in the Song Dynasty (960-1279), and was located in Jianyang of East China's Fujian Province. The kiln was known for its production of the famous black porcelain, which was first made during the Tang Dynasty (618-907), flourished in the Song Dynasty, especially during the Southern Song Dynasty (1127-1279), and declined by the Qing Dynasty (1644-1911).
The black porcelain of Jian ware had a purplish black paste and a thick lustrous black glaze. A silver gloss showing through the black glaze resembled rabbit hair, partridge feathers, or oil spots.
Small "rabbit-hair" cups were the most popular items of Jian ware and were preferred for the tea-tasting contests prevalent in the Song Dynasty.
