This set of bronze vessels comes form one of the many pits surrounding an as yet unopned tomb, probabaly that of the consort of thr king who was buried at Shizishan close to where Yanguishan is located. The set consists of a steamer zang whose foot ring perfectly fits the cauldron fu below. The culdron would have been filled with water and placed on a tripod over fire. The steam that bulit up would eascape through the perforations in the steamer, allowing the food to cook. Alternatively, the cauldron and steamer could be placed on a stove resting on the 4 projections that are cast on where the circumference is widest. 2 loop handels on each allow both steamer and cauldron to be lifted. Modle of stoves holding steamers and cauldrons illustrating such use have been found in Han period tombs, such sa in a Western Han period burial excavated in Louyang, Henan.
