Tea drinking became popular among folks in the Song dynasty, and there were a lot of porcelain wares that produced tea sets, e.g., the Five Famous Wares – Guan, Ge, Ding, Ru, Jun.. Jian’ou Beiyuan tea was royal tribute. Its dragon and phoenix tea cakes are best if pure white in color. In addition, there were severe competitions, and black glaze calyx and kettle were often winners, e.g. Jian’s rabbit calyx, Jizhou’s flecked calyx, hawksbill calyx, leaf line and paper-cut applique dark glaze calyx, and Cizhou’s rusty black glaze calyx. Apart from that, blue glaze tea sets were also mass-produced in Longquan (South) and Yaozhou (North). The bamboo hat bowl is a typical tea ware in the Song dynasty.
