A poem by Du Fu of the Tang dynasty. The poem comprises 204 seals made from porcelain. The seals are made using the bisque firing at 920°C until the porcelain is hard as stone and the carvings are made in oracle bone and bronze scripts. The seals are then applied onto pieces of porcelain to make "sealing clays" and are fired at 1260°C.
