Chinese Yixing clay teapots are made from unique clay deposits found in the hills of Yixing, known as zisha or "purple sand". The unglazed nature of the clay allows the teapot to absorb trace amounts of tea flavors over time, which is believed to enhance the taste of future brews of the same type of tea. The teapots are highly valued by tea drinkers and collectors for their rustic elegance and functionality in traditional Gongfu tea ceremonies.
