Excellent teapot. This rare Zhu Sha has a distinct, high-granularity texture and great thermal stability. It performs very well with high-end Gushu (like Guafengzhai Chawangshu, Bingdao, and high-altitude Yiwu), preserving the aroma while adding depth to the body. The craftsmanship by Gu Xiao Ming is precise, with a clean and balanced pour. A solid addition to the collection.
