Only four other buckets of this type are known to exist and three of them are in major museum collections. The whereabouts of the final bucket is unknown. The bucket would have been passed around at the beginning or end of a meal for guests to rinse their fingers - the inscription appearing around the vessel reads 'I am a toy for the fingers shaped as (in the form of) a vessel. I contain cool water'.
