Yixing clay, also known as terracotta, comes from the area near the city of Yixing in Jiangsu province, China. This type of clay has been used in pottery since the Song Dynasty (960–1279).

The unglazed surface of Yixing teaware allows the absorption of the beverage, thereby creating a more complex flavor. Thus, Yixing teaware should only be washed with water and no soap. Some go as far as to suggest only one type of tea (white, green, oolong, black, or pu'er) should be used per vessel.
