Intangible heritage is living cultural heritage which can express human’s wisdom and sensibility intactly by this time. Even though some of them already disappeared, are about to disappear and would disappear not before long, there still remain many of them in our thoughts and experiences. Such heritage is the infinite future resources and traces of the past that human can enjoy in this digital era. The traditional cultures can play a more important role for us in feeling human’s emotions and humanity in the digital era because they contain old human’s memories, and can be an economic means as well. These intangible heritages, in essence, may have the same function even though their forms are different. In particular, we can see that certain cultures spread to neighboring regions, which led to the creation of a new form of culture in a community that accepted them. This process is important as an asset for sharing humanity and at the same time becomes a meaningful source for each community to have its cultural identity as an expression of diversity of human thought. Therefore, how to preserve the shared or coexisting intangible heritage among cultural communities is a key topic in the international society today. Meantime, there have been some cases in which even though they are the same kind of heritage, certain heritages in some areas were inscribed on the list of World Heritage but others were pushed aside, in spite of their equally excellent values. In today’s fast-changing society, if culture is neglected even a little bit, it will disappear. Then, if it disappears, total amount of culture in that society will eventually shrink, which means that the future values will be lost. What is called culture inevitably comes to vanish without those who use it, no matter how creative it is. In order to preserve traditional heritage that may disappear at any time, it is an essential process to persuade the society, develop modern utility and seek for strategic methods, deeply thinking of its future value of such heritage. To preserve the intangible heritage, it is necessary to build the favorable environment in which communities with such technological culture can keep working on new creative works. For this, each society has to make continuous efforts in cooperation with communities not to wither this heritage away. These efforts are important not only in terms of the transmission of tradition but also as cultural resource to form sustainability for a society in the digital era. Here, we should pay keen attentions to preventing such intangible heritage from being fossilized, remaining fixed cultural system and eventually being eliminated. Intangible heritage should exist as one culture, but its way of expression should adapt to the senses and demands of a new generation by constantly making creative transformation. By doing so, the original form can be also preserved as a part of diversity. In other words, the practical benefit based on tradition is a prerequisite for the transmission through generations.

Human has made great progress beyond the speed of biological evolution by using tools. First, human used stones and wood as tools for hunting and gathering, and then invented earth-baked earthenware such as bowls for food, appropriate to farming life. The defects of woodenware and earthenware, however, were obvious. It was not able to contain liquid due to their moisture absorbency, and easily damaged. Earthenware has evolved into glazed ceramic but it required a high-tech kiln with high temperature, accompanied by a technology for metal refining as a key prerequisite. In East Asia, moisture proof and insect proof techniques to coat objects were invented much earlier. That is lacquer technique. Production process of lacquer is delicate and complicated such as handling lacquer sap at the risk of skin disease, creating hot and humid environment for hardening process, etc. Nevertheless, in East Asia, people have used lacquer technique in many regions from the Neolithic Age, knowing its merits earlier on. Lacquer was used for adhesive and surface protection of leather, earthenware, ceramics and metalware. In particular, it has been inextricably linked to wooden objects. Whereas in West Asia and Europe various varnishes mixed with dry oil and resin has been used, in East Asia lacquer was used as a basic varnish in common. That shows that lacquer is great material and technique to represent the commonality of Asian culture.1) This article aims to briefly look into the origin of lacquer technique in Northeast Asia and share the information on it and its current status of transmission.

The geography of Korea is ideal for growing lacquer trees. Optimal climate, topography, and soil conditions can be found across the country, and the lacquer produced is of the highest quality. This led to lacquerware crafts being highly valued in Korea over the years, and a uniquely Korean culture of lacquerware being developed.
