  • The gold textile is Korean traditional weaving technique using the gold thread since 5th century. The making technique of gold thread was written in various references, but it is severed because the gold thread weaving equipment and sumptuous moods were forbidden in the early 18th century. There are some studies of traditional gold thread which are mainly about conservation treatment of cleaning and strength. To restore traditional gold thread, investigation of material and manufacturing technique is vitally required. The gold threads are composed of gold leaf, adhesive and base sheet. Gold leaf and base sheet are available for investigation because they are exposed to the surface, whereas adhesive is not easy to investigate because it is not exposed to the surface. In this study, samples are made of pure and impure gold, animal glue and lacquer, and various types of Hanji based on domestic and foreign references to compare materials for gold threads. As a result of morphological character and stability evaluation, the optimum materials for the restoration of gold threads are pure gold, animal glue and Dochimji(smoothing paper by beating). This study is expected to be basic data for manufacturing gold threads techniques and modernization of traditional gold threads hereafter research.

  • This study was conducted focusing on the stability on materials of cultural property when the fumigant containing ethylene oxide was applied among some kinds of fumigant. Four kinds of specimens from paper, textile, metal and pigment were prepared to compare color difference, weight, surface condition before and after treatment and FT-IR analysis was carried out on specimens of paper and textile. In the case of fumigation treatment, it was conducted by two groups : one is made up of specimens with the non-fumigation as control groups, the other is made up of specimens treated with ethylene oxide + $HFC_{134a}$ and ethylene oxide + $CO_2$ as experimental groups. The result of color difference showed that there were color differences on the specimens of Hanji(Korean traditional paper), silver, cotton, ramie and yellow pigment. Especially, it was found out there was color change more than 6.0 on average from the silver specimen. However, in the silver specimen's case, color change in the non-fumigated specimen was relatively higher than those of fumigant-treated specimens, therefore, it is judged that fumigant doesn't have a decisive effect on color change in specimens, but required caution while fumigating. The result of weight measurement, there were totally 0~2% weight changes and the slightest change was found in the metal specimen, the biggest change in the papers. The result of microscopic observation on the surface of specimens showed color changes and especially, the biggest change on the silver specimen was observed. But no change in components was identified from FT-IR analysis of papers and textiles.

An Experimental Study on the Printing Characteristics of Traditional Korean Paper (Hanji) Using a Replicated Woodblock of Wanpanbon Edition Shimcheongjeon (완판본(完板本) 심청전 복각 목판을 이용한 한지상의 인출특성에 관한 실험적 연구)

  • When investigating old, printed documents, determining whether a work is printed on a woodblock or using a movable metal type is crucial. It is because the history of printing in Korea and across the world relies on determining the relevant printing invention used and the time of use of the movable metal type. Deciphering details from woodblock and metal prints requires various kinds of information regarding the imprint and the work's printing background, such as information on the characters in the printed document, the outline of the pages, the type of ink used, the production period of the ink, and the production period of the Korean paper. Analyzing such information can generally reveal the production period and the methods used on the old document. However, as such information is not documented systematically, relying on the researcher's judgment based on their experience and perception becomes inevitable. This study conducted an experimental investigation of the printing characteristics of woodblock prints using a replicated woodblock of the Wanpanbon edition of the Shimcheongjeon. Subsequently, the various phenomena and characteristics appearing on the woodblock prints were documented for future reference to determine the printing method of old documents. Finally, woodblock novels without an imprint may be used as a reference to estimate the printing dates by determining the degree of wear on the woodblock.

  • The patterns for Jeogui and Pyeseul (patterns of the queen's ceremonial robe worn and a belt ornament covering knees in the front) as owned by National Museum of Korea were made in the early 20th century and both of them were colored on paper. Through a non-destructive analysis on pigments and dyes used on both the patterns, it was attempted to identify the coloring materials. As for the analysis of the coloring pigments, the XRF was used. As a result of the pigment analysis on the pattern for Jeogui, it is presumed that lead white was used for obtaining the white color, ink stick for black color, orpiment for yellow color, cinnabar and red lead for red color, copper and arsenical or a mixture of copper carbonate and orpiment for green color whereas brass seems to have been used for obtaining other colors. The pigments used for obtaining the colors of white, black, yellow and green on the pattern for Pyeseul are the same as those used on the pattern for Jeogui whereas the red pigments used on each of the two patterns are seen to be different. Although it may be difficult to identify the kinds of blue pigments that were used on the patterns for Jeogui and Pyeseul, a mixture containing lead white is presumed to be used as blue pigment. Also, as a result of the UV-Vis spectroscopic analysis performed on the blue hanji (traditional Korean paper) of the pattern for Jeogui, it was presumed to have been dyed with indigo.

  • Several members of the genus Broussonetia are woody plants with high-quality cellulose fibers and are used to make a traditional type of Korean paper known as Hanji. Three of these species, Broussonetia kazinoki, Broussonetia monoica, and Broussonetia papyrifera, are found in the Korean Peninsula. Because it is challenging to distinguish different Broussonetia species based on morphology alone, we have developed a set of insertion/deletion (InDel) markers for genetic identification of these species. From twenty-two Broussonetia samples collected throughout Korea, we selected six for next-generation sequencing analysis. InDel marker candidates were identified by comparing this sequence information with the B. kazinoki chloroplast genome sequence. The marker candidates were used to screen the genomes of the twenty-two Broussonetia plants, and five useful chloroplast-based InDel markers were identified. Detailed genotyping using these five markers showed that the twenty-two plants of the genus Broussonetia could be clustered into five groups, verifying that the markers developed here can be used for breeding, identification, and analysis of species in the genus Broussonetia.
