This study focuses on combining traditional craft lacquer thread sculpture and augmented reality (AR) technology to develop digital educational content. In this way, we not only make it easier and easier for children to learn and understand the traditional craftsmanship of lacquer thread sculpture, but also finds a new direction for traditional craft education. First, through literature research, the production process of traditional craft lacquer thread sculpture is summarized. Through an in-depth understanding of traditional craft lacquer thread sculpture, it provides a theoretical basis for subsequent AR digital content development to achieve educational goals. Next, we used AR technology to design and produce the digital content of the traditional craft lacquer thread sculpture. This study proposes the application of AR technology and the design and production methods of digital content. It is hoped that the methods and experiences we have proposed will not only provide reference for the development of similar digital content in the future, but also provide new educational methods for the inheritance of traditional crafts.

Lacquer has a high value as a coating of typical arts and crafts in East Asia including Korea, Japan, and China and traditional representative of the gorgeous satin that is fit to the cultural conditions of each region. Lacquer is harmless to the human body and its robustness, preservatives, moth proofness, and strong heat resistance can maintain a long life. It seems that it will be able to make a significant contribution to create a variety of products if we continually study and raise the productivity and quality of the goodness of these lacquer. In this context, we reviewed the Pitae lacquer wares, which is one of the lacquer of traditional techniques that can be applied to the development of daily necessities and cultural product. Joining the goodness of harmless and environment-friendly lacquer and the characteristics of the leather that can produce a variety of physical beauty can develop household goods of tradition and modernity in harmony. It is worthwhile re-interpreting the tradition in the aspect that we can develop our culture from a modern, plastic, and artistic point of view.

Scientific methods for grading urushi lacquer includes general properties (viscosity, pH etc), and quantitative analysis of moisture, urushiol, gum, laccase content etc, and properties of coating layer such as set to touch drying time, gloss, color difference, delamination strength, tensile strength of film. The grading results evaluated by scientific method showed n order with chinese urushi lacquer (E) > domestic urushi lacquer (A) > japanese urushi lacquer (C) > chinese urushi lacquer (D) > domestic urushi lacquer (B). It is different from hose of traditional methods. Therefore, a more accurate grading of urushi lacquer should be ade by combining traditional method with scientific method.

The traditional culture, which is a historical product possessed by each country, represents the competitiveness of the country and becomes a national resource. Raw lacquer has a very long history and tradition in China. Lacquer, which is the basic material of Raw lacquer. Also it is a natural paint which has the functions of preservation, insectproof and waterproof used from ancient times in Asia, not only in China but also in Korea and Japan. Such Raw lacquer using lacquer has a long history and it is becomes to a tradition. On the other hand, Its value and meaning are being faded by oilpaintings and watercolors. Much effort and research are needed to become more popular. I would like to introduce the lacquering technique in illustration as one way. There are a lots of expression techniques in the present illustration, but lacquer expression is rarely seen. In the illustration, lacquering technique is a modern reinterpretation of traditional culture by combining modern technology with traditional culture. In this paper, a Raw lacquer with a long tradition of soul is informed to the public and it is a way to bring attention to the beauty of lacquer and reproduce the original expression technique as an illustration to enhance the understanding of traditional culture, I hope that Raw lacquer will be used in the field.

The purpose of this experiment is to understand a possibility for the techniques of collecting the Korean Rhus lacquer by the traditional method(Hwachil) against the diminishing lacquer industry. Hwachil method, making use of fire to collect lacquer, is practiced at only some areas, but the lacquer is very efficacious for foods and oriental medicine. A comparative experiment between traditional method and new machine method by processing unit 5 kg of lacquer tree was made to improve Hwachil method technically. The results showed that the machine method produced more about 45% of lacquer than the traditional one. The traditional method, moreover, needed intense labour quality and high leveled techniques, which caused to bring physical sufferings. In comparison with the traditional method for the collecting time required, the machine one showed to take more than minutes per a unit. But the machine method was easy and convenient to handle the machine without special techniques.

Grading of the urushi lacquer is quite difficult because of large variations depending on origin, growing conditions, time acquisition, storage conditions. It is urgently required to establish a grading system of urushi lacquer by combining traditional method with scientific methods. Traditional grading of urushi lacquer was done by visual inspection of 10 experts who are working on urushi lacquer industry. Common aspects of the experts were color, odor, viscosity, spread properties on Hanji, color and drying properties on glass based the traditional grading system. In addition, rubbing on Hannj and heating with alcohol lamp was also used to grade urushi lacquer. The grading results of 10 experts showed that chinese urushi lacquer (E) of 7.03, japanese urushi lacquer (C) of 6.84, domestic urushi lacquer of (A) of 6.41 and another chinese urushi lacquer (D) of 5.27, and domestic urushi lacquer (B) of 2.50 in descending order. The degree of spread on Hanji was not consistent among 10 experts. These results indicated that the traditional grading system was pretty much personal and required of developing more objective method based on scientific background.

Furniture is a medium to interconnect the living space to human, and it is the closest environmental element that limits the functions of the space, defines the style of the living, and adjusts the actions and behaviors of human. Therefore the furniture can be said to be one of the craft arts that reflects the culture and living style as they are according to the periodical, regional, and social stratum characteristics. Within this context, this study tries to suggest new design and living culture that can harmonize with the modern residence living culture and incorporate the traditional varnishing technique with lacquer that had been discontinued. Coming to the modern days, the varnishing with lacquer is getting attention again with its environment friendly characteristics and antibiotic functions, and is being applied to various applications. To inherit and maintain such an excellent traditional culture, I would like to improve the practicality by applying to modern furniture, and to contribute to develop and tell the world about the superiority of our culture.

The lacquer is one of the most important resources for endogenous development and cultural reproduction in Wonju. However traditional and social network, which had been formed by lacquer farmers, group of lacquer-pickers, refineries, and lacquer-ware craftsmen, is being collapsed. It is due to the recent imports of raw lacquer from China and refined lacquer from Japan. Public sectors including Wonju city have continuously improved the potential of lacquer production by planting lacquers. However, the potential of lacquer production isn't under enough condition to realize its value. In this study, it is suggested that the efforts of public sectors to raise lacquer industry, focused on the improvements of lacquer production potential until now, should be concentrated on realization of the production potential by reconstructing social productive system which is composed of diverse groups involved in lacquer ware production.

In this study, we investigated the weathering properties of Korean Rhus lacquers containing tung oil and their potential use as exterior coatings. The finished lacquers were prepared with a raw Korean Rhus lacquer or refined Korean Rhus lacquer content of 10, 20, 30 and 40 wt.% (corresponding to ratios of 10/90, 20/80, 30/70 and 40/60 by weight of Korean Rhus lacquer/tung oil, respectively). The curing temperature of the prepared lacquer increased with increasing the content of the raw Korean Rhus lacquer. This increased curing temperature is related to higher proportion of hydroxyl groups in the prepared lacquer, due to the content of the raw Korean Rhus lacquer. In accelerated weathering testing, the changes in the gloss and contact angle of the prepared lacquers showed a similar trend to that of traditional exterior oil stain. In addition, the prepared lacquers containing tung oil showed greater discoloration than traditional exterior oil stain. However, the discoloration of the prepared lacquer with a raw Korean Rhus lacquer content of 40 wt.%, and that of the prepared lacquer with refined Korean Rhus lacquer contents of 30 wt.% and 40 wt.%, showed a similar trend to that of traditional exterior oil stain. Consequentially, these prepared lacquers showed a potential for being used as exterior coatings.

This study uses traditional lacquer techniques to coat the metal surface and evaluates its physical properties to check the applicability of the lacquer coating. For this purpose, a total of six specimens were produced by setting the variation conditions for the number of times (1, 2, 3) and the heating temperature (120℃, 150℃) using SS275 metal(60*60 mm) and 'Wonju lacquer'. For analysis, chromaticity measurements, contact angle/surface energy measurements, Chemical Resistance, and cross-cut tests were used. The analysis showed that the corrosivity was improved and the adhesion of lacquer to the metal surface was excellent. There was no significant change in contact angle/surface energy. Also, there was no significant difference in color. Through this study, it was confirmed that lacquer on metal surfaces improves waterproofing and has a anticorrosion effect. We could also check the proper number of lacquer and heating temperature. Additional physical characteristics such as hardness and wear rate should be studied. It is also necessary to study how lacquer can be painted with a certain thickness.
