this was the second pot i commissioned by master Zhang Ke. Ian advised me in the clay a year ago and so it became a pot in Kui Huang Duan clay. The clay feels a little sandier than other clays and the pot is somewhat heavier. But what a beauty it is, well worth the wait! The skills of master Zhang Ke are second to none. It came in a beautiful box, well wrapped as always! i thank master Zhang ke wholeheartedly for this beautiful piece of art and Ian an Yi-Lei for taking such good care of their customers and making Yixing available for the broader public.
