==History==


Bangjja brassware reflects its deep historical value as well as traditional fashion of Korea. The history of Bangjja starts from the Bronze Age and it was widely used to make a variety of tools and tableware. Ordos region’s bronze culture related to Scythian Bronze Culture was spread and affected several regions including Korean territory. As the Bronze Age culture in Korea was influenced by Ordos region, where bronze culture was originated from the northern part of Siberia, Korean also produced ceremonial products such as ritual tools with bronze.

In the period of Chosun dynasty, the country greatly supported mining and established many brassware plants in local territories. Although, people in this era generally used porcelains, upper-class people continued using brassware like Goryeo period. As time passed, even in the middle class, people started using brassware increasingly and it formed many markets across the country.

In the end of modern age, most of brassware in all households got ravished by Japan. With the liberation in 1945, brassware became widely used again, but soon after Korean War, when briquettes took place, people preferred stainless bowls to brassware because brassware gets easily discolored by briquettes gas.

In reversal, nowadays, through various chemical experiments, Bangjja brassware is becoming famous and known for its O-157 sterilization function, anti pathogen, and detection of pesticides. Also its heat retention rate turned out to be higher than porcelains and stainless bowls. Bangjja is currently used for making instruments, tableware, and other various goods such as household supplies.

When ''bangjja'' bronzeware is made, a mass of alloy of copper and tin is heated with fire and gets hammered several times. The proportion of tin in ''bangjja'' bronzeware is very high compared to general bronze bowls.


In general, iron becomes more firm when it is quenched after being heated in fire over 600 degree. However, ''bangjja'' bronzeware becomes softer as it gets heated in fire. This is another mystery of brassware. Several people form a circle around the ingot and start hammering to make a form of plates. 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.

== Today's ''bangjja'' ==
First of all, mass of brass nugget is made by alloying copper and tin in ratio of 78:22, which is a golden ratio which permits no error at all. Interestingly enough, this alloying ratio is not possible in modern metallographic study because in today’s practical products, the proportion of tin must be under 10 percent. Surprisingly, though Bangjja brassware has to be made with the ratio of 78:22. According to modern theology, the existence of Bangjja brassware is unexplainable.
''Bangjja'' bronzeware produced by handed down traditional techniques till today are not bent or easily broken. Furthermore, with more usage, it becomes burnished without any discoloration. Recent reports about various experiments revealed that ''bangjja'' bronzeware contains a sterilization function and detects pesticides. ''Bangjja'' bronzeware, now called "bowl of mystery" shows its great heat retention, which is far greater than other tableware made with other materials. It is also commonly used as a material for percussion instruments like the tam-tam, hobnail, and gong.


Several people form a well organized group to produce ''bangjja'' and it requires complicated and highly skilled techniques to be done, which makes ''bangjja'' more distinctive. ''Bangjja'' products are used not only as simple household supplies, but also as work of art, which depicts the traditional custom of Korea. The value of ''bangjja'' bronzeware is highly respected. ''Bangjja'' artisan Lee Bong Ju, who was appointed as Important Intangible Cultural Property in 1983, has his works sold at his company [[Napcheong Bronzeware]]. Many of his works are now exhibited at Daegu Bangjja Bronzeware Museum.<ref name=":2">{{Cite web |last=엄 |first=민용 |last2=남 |first2=소라 |date=2017-11-26 |title=[서울 그집 ‘오래가게’] 납청놋전…최고의 합금술 ‘방짜’의 매력 폴폴 |url=https://www.khan.co.kr/feature_story/article/201711261539001 |access-date=2024-08-19 |website=경향신문 |language=ko}}</ref>
In addition, the robustness of Bangjja brassware is semi-permanent and its placid emotion reflected by its beautiful color is not comparable to any other bowl in the world. It is due to this golden ratio. Interesting part is that the brassware cannot endure hammerings without this ratio.

In general, iron becomes more firm when it is quenched after being heated in fire over 1 Celsius nectarine. However, Bangjja brassware becomes softer as it gets heated in fire. This is another mystery of brassware. Several people form a united circle around the mass of annoy and start hammering to make a form of plates. 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 brassware.

'''Today's Bangjja'''

Bangjja brassware produced by handed down traditional techniques till today are not bent or easily broken. Furthermore, with more of usage, it becomes burnishing without any discoloration. Recent reports about various experiments revealed that Bangjja brassware contains sterilization function and detects pesticides. Bangjja brassware, now called as a bowl of mystery shows its great heat retention rates, which is far greater than other tableware made with other materials. Since Bangjja is completely free from toxicity, it is also commonly used as materials for percussion instruments like tam-tam, hobnail, and gong. The sound of the instrument is totally depended on one hammering of artisans at a time.

Several people form a well organized group to produce Bangjja and it requires complicated and highly skilled techniques to be done, which makes Bangjja more distinctive. Bangjja products are used not only as simple household supplies, but also as work of art, which depicts traditional custom of Korean. The value of Bangjja brassware is highly respected and it also has a profound mystery, which is unable to be explained by scientific knowledge because Bangjja brassware is the only metal product that is made by a craftsman. A Bangjja artisan Lee Bong-Ju, who was appointed as Important Intangible Cultural Property in 1983 is currently maintaining the root of Bangjja in South Korea. All of his various masterpieces are now exhibited at Dae-Gu Bangjja Brassware Museum.

Bangjja (Korean방짜), also called yugi (Korean유기; Hanja鍮器), is a Korean type of hand-forged bronzeware. A complete set of bangjja includes dishes, bowls, spoons, and chopsticks. The main difference between Korean bronzeware or bangjja from other bronzeware is the alloy ratio between copper and tin. The bangjja contains much more tin than other bronzewares (Cu:Sn = 78:22 as volume) while the normal ratio of tin to copper is 1/9. Due to this compositional difference, bangjja (unlike other kinds of bronzeware) can be sterilized. For this reason, it has historically been used as tableware for the royal families of Korea. Bangjja is used for the traditional presentation of Korean royal court cuisine (surasang). In 1983, the government of South Korea officially designated bangjjaa as an Important Intangible Cultural Property.
