Jianshui purple refers to Jianshui Zitao (建水紫陶), a type of high-quality purple clay pottery originating from Jianshui County in Yunnan Province, China. This traditional pottery is crafted using natural clay rich in iron and other minerals, giving it its distinctive purple, black, or reddish-brown hues. Jianshui purple pottery is celebrated for its smooth texture, intricate designs, and exceptional durability.

A hallmark of Jianshui pottery is the "carved and filled" technique, where artisans carve delicate patterns or calligraphy into the clay, fill the grooves with contrasting clay, and polish the surface to create a smooth, seamless finish. The final result often showcases artistic motifs and a glossy, refined surface without the need for additional glaze.
