This one is a must for Yixing teapot collector. One of the last batch from the famous Yixing teapot factory in the mid 90's using early 90's clay. The fabrication process of the clay is outstanding and the very light weight of this Yixing teapot is a testimonial to that.
This quite rare clay is called Tiao Sha Hei Pin Zi. It is a mix of the elusive hei ni (black clay) and pin zi ni and will allow any type of tea to be brewe in this Yixing teapot.
