Jian ware tea bowls, produced in the kilns of Jianyang (modern-day Fujian province), are among the most revered ceramics of the Song Dynasty. Characterized by their dark, often black, glazes, often displaying a unique hare's fur or oil spot effect, Jian ware tea bowls were particularly prized by Zen Buddhist monks and tea connoisseurs for their aesthetic and functional qualities. The dark hues and varied patterning made them ideal for showcasing the light colour of the tea itself.
