Zisha is a type of clay used primarily in the making of teapots and other tea-related items in China. Known for its unique properties, Zisha clay is porous, allowing it to absorb the flavors and aromas of tea over time, enhancing the drinking experience. The clay is often hand-crafted into intricate designs, making each piece a work of art. The term "Zisha" translates to "purple sand," referring to the clay's natural color. This material is sourced from the Yixing region, famous for its rich deposits. Zisha teapots are highly valued among tea enthusiasts for their ability to improve the taste of brewed tea.
