These 90 ml Zini teapots were completely handmade in the Iron Arhant style by Chen Ju Fang from Wuxing Shan Fang studio in Yixing. The clay is highest quality #2 aged Zini clay. The pots are handmade by a master potter with a lifetime of experience. Due to the incredibly pure, high quality clay and masterful production, the pot softens the water, pouring with great control and accuracy, maintaining heat and aesthetically beautiful. The lid fits very well. Ideal for Puerh, Yencha or Liu Bao. We suggest using this pot for one class of tea as the clay is porous and will absorb the tea used.
