We had these 'Gong Fu' tea 'islands' made for us and stamped with the Imperial teas chop mark. They are made from the finest Yixing clay, famous because its unique properties enhance the fragrance and flavour of the best teas, and created by a master craftsman in Taiwan. When you have brewed the tea to perfection in the matching 'Gong Fu' tea pot it is decanted into the tea island then distributed to the four tea bowls, ensuring an equal strength of tea for all.
