During the period of the Goryeo dynasty when they frequently traded with China, royalties and nobles used thin bronze tableware made with bangjja technique.

In the period of Chosun dynasty, the country greatly supported mining and established many brassware plants in local territories.

In the end of modern age, most of bronzeware in all households got ravished by Japan, and they were melted down for their metal during World War II.

In reversal, nowadays, through various chemical experiments, bangjja bronzeware is becoming famous and known for its O-157 sterilization function, anti pathogen, and detection of pesticides.

One special thing about the process is that they do not use ready-made mold machine, instead they repeat hammering and heating in fire as they are making the shape of bronzeware.

Bangjja bronzeware, now called "bowl of mystery" shows its great heat retention, which is far greater than other tableware made with other materials.

Bangjja artisan Lee Bong Ju, who was appointed as Important Intangible Cultural Property in 1983, has his works sold at his company Napcheong Bronzeware.
