A teapot made of stoneware of blueschist/glaucophane schist from Taiwan. Zhuyeshi is the chinese name for this rock. These teapots made of stoneware are the fruit of great craftsmanship. They are also difficult to find, in the past years we did not find any that we would purchase. The present pots are the work of the artist Huang Longxian. He is a rather old-fashioned Master, going about his business unaware of marketing strategies and other such things. His works don't even come in beautiful boxes, never mind certificates with pictures or descriptions of the piece.
