Numerous bowl-shaped bronze cauldrons were found in South Siberia so it is likely that this type of cauldron originated from the Scythian culture which dates to 7th - 5th centuries. Similar ancient cauldrons have been found throughout central Asia, Mongolia and northern China. The earliest of these is dated to the 8th century and originated in China. They then spread to the west as the Eurasian people settled near the Black Sea. During the Hunnu period, bowl-shaped cauldrons were popularly used in Mongolia and commonly found in Hunnu burials. In archaeological research this type of cauldron is therefore called the Hunnu cauldron.
