The green pigments of shamanic paintings (83 items) in the 19~20th century were analyzed with X-ray fluorescent spectrometer(XRF), scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (ATR-FTIR). In 60 items, copper and arsenic were detected in green pigments of the paintings by XRF spectra. Cu
(peak intensity ratio of copper and arsenic) of shamanic paintings of Bokgaedang (shrine), solemn paintings (romance of three kingdoms) of Donggwanwangmyo and unknown enshrined place were 5.93~12.04 and higher compared to 5.67-6.26 of standard emerald greens and 4.01~7.89 of remaining shamanic paintings. The SEM images of crystal forms of copper-arsenic green pigments were various. Crystal forms were divided into oval and round spherulite with intersecting plate crystals and spherulite with agglomerate plate crystals. The crystals of the latter were found in shamanic paintings of Bokgaedang (shrine), solemn paintings (romance of three kingdoms) of Donggwanwangmyo and unknown enshrined place and the former were found in the rest of shamanic paintings. Copper-arsenic green pigments of shamanic paintings were identified as Scheele`s green from shamanic paintings of Bokgaedang (shrine) and romance of three kingdoms. Emerald green from the rest of shamanic paintings by ATR-FTIR. From analytical results, it is confirmed that Scheele`s green of shamanic paintings of Bokgaedang and romance of three kingdoms was used in the 1850s~1870s and emerald green had been widely used from late 19th century to 1970 in the rest of shamanic paintings.

"Jocheonillgi", one of the articles left by Jo Heon(1544~1592) whose pen name was Jung-bong, is a travelogue which was written in around 1574~1575 when he was dispatched to Ming as a formal envoy(Giljungkwan). The diary-style manuscript was designated as one of the pieces of the National Treasure 1007. Due to the damage of its binding strings, abrasion, fold, stain, insect and damage on the surface, conservation and restoration was needed. In the process of separation, three more binding strings were found, confirming that the travelogue was rebound at least twice in the past. In addition, the page of `Yeondoillgi`, the original title, was bound inside, confirming that the current cover was revised in the past. As the result of the investigation of base fabric, paper mulberry was found to be the cover, inside paper, lining paper, paper strings. The three kinds of binding string including the current ones was defined to be silk.

Fungi were isolated from mural painting in tomb no.6 at songsan-ri, Gong-ju. Antifungal susceptibility of essential oils extracted from natural medicine was tested and it confirmed applicability for mural painting in tombs. 26 species of fungi collected from air-borne and wall surfaces were identified to 15 species of Ascomycetes, 2 species of Zygomycetes, 1 of Basidiomycetes. Wheat starch and gelatin degradability were evaluated as isolated fungi. SY-18, SY-23, SY-25 showed high degradability of wheat starch. SY-18, SY-21, SY-23 were decomposed into gelatin. Biochemical characteristics of decomposing fungi to wheat starch glue and cowhide glue were analyzed by using
and gelatinase activity. An Antifungal test was conducted in Anethole and Eugenol. Anethole and Eugenol mixture(1:2) showed high antifungal susceptibility. Natural adhesives help microbial growth and can cause structural damage in mural painting. The expectation of this study is the possibility to control microbial growth in wall painting using natural essential oils. It can be used as a data for conservation method to control microbial damages.

In this study, the stability of the adhesive was determined through the Oddy Test that is Verification Test for potential damage by various materials. And to find the factor causing the corrosion of the metal samples, the adhesives and coatings those are usually used in the metal preservation process were selected and treated on the samples. Six kinds of adhesives and four kinds of metal specimens Fe, Pb, Cu, Ag were used. As results, the weight change showed high increasement in the rate of weight change 29.87% of Fe sample. The chromaticity measurement showed the high change value of the Cellulose-based adhesive. In case of the VOCs test from adhesive by using GC-MS, Acetic acid was detected from all six kinds of the adhesives. Compared to cellulose-based adhesives and the other adhesives, the amount of VOCs per 1mg concentration is higher than 900 times and was detected small amount of Formic acid. This is assumed to be facilitated by acid impurities and the light. This reaction was considered as the result of reducing a large amount of molecular and of generating a large amount of Nox. And thus the reacted sulfur changes was considered as the factor for causing corrosion.

DOI : 10.12654/JCS.2015.31.3.06
In this study, the potash glass beads of 281 samples in 30 sites analyzed until now were classified according to the chemical composition. And the color, size, manufacturing technique and distribution period were compared. Korea potash glass beads are divided into 3 types depending on the stabilizer content. I, II type is the CaO and
content of less than 5%. Relatively, I type has a high CaO and II type has a high
. In contrast, III type comprises more than CaO 5%. I, II type is the saltpetre, III type is estimated using plant ash as row material of flux. A review of the properties by type, I type is cobalt blue, copper blue and purple beads. The outer diameter is sized to the range 1.4~7.4mm. Also it was produced by the drawing technique. It was used continuously from BC 1C until around AD 6C. On the other hand, II type is outer diameter of 1.9~3.6mm and a copper blue beads. manufacturing technique is the same as the I type. This seems to have been in use since around AD 1C to 4C. Finally, III type is brown, colorless, amber beads and an outer diameter of about 10mm. It was formed by winding technique and appeared in the tombs of Goryeo and Joseon Dynasty. As a result, 3 types of potash glass beads distributed in Korea is likely to flowing through the various trade routes from different provenances.
A Study on Selection of Ultrasonic Transducer and Contact Material for Surface Irregularities of Stone Cultural Heritage
Jo, Young Hoon ; Lee, Chan Hee ;
Journal of Conservation Science, volume 31, issue 3, 2015, Pages 267~278
DOI : 10.12654/JCS.2015.31.3.07
In this study, the elastomer cover, a new contact material, was developed to establish the customized ultrasonic measurement considering surface irregularities of stone cultural heritages. The cover exhibits high elastic force and wear resistance because it has tensile strength of 17MPa and elongation of 625%. In addition, as a result of comparative experiments for the seven types according to transducers and contact materials including the elastomer cover, rock surface irregularities significantly affect attenuation of ultrasonic velocity. The phenomenon was more noticeable in the chiseling finish and indirect transmission measurement rather than the dabbed finish and direct transmission measurement. However, the Type F using the exponential transducer and elastomer cover showed stable P-wave velocity and high amplitude regardless of the surface irregularities. This because the elastomer cover sufficiently sticks to surface irregularities and removes pores between a transducer and a rock specimen. Therefore, the Type F should be used for the ultrasonic measurement of stone cultural heritages with surface irregularities.

DOI : 10.12654/JCS.2015.31.3.10
Aim of this study is to identify dyestuff of the Dallryeong(official`s robe in Joseon Dynasty, 16th century) excavated from Yuryang-dong, Cheonan, in 1996. For this purpose, extracted dyestuffs from Dallryeong fabric and from natural dyestuffs for red color(safflower, Sapanwood, Madder) which are presumed to have been used in the Dallryeong, are analyzed and compared by high performance liquid chromatography(HPLC). As a result, HPLC chromatogram of extracts of the Dallryeong`s dyestuff and safflower are showed a peak at 17.5 minutes. The UV/Vis spectra of the samples are showed the maximum absorption wavelength at 519nm. This result is identical with the analysis of the previous studies on red dyestuff of safflower. In addition, the analysis of Mass Spectrometry(MS) showed the identical result of the peak with m/z 910. Following these results, excavated pink Dallryeong were considered to have been dyed with safflower.

Lee, Jae-sung ; Jeon, Ik-hwan ;
Journal of Conservation Science, volume 31, issue 3, 2015, Pages 309~318
DOI : 10.12654/JCS.2015.31.3.11
The staff given with chair to Yi Gyeong-seok, senior official over 70 years old by King Hyeonjong of Joseon Dynasty is representative handcraft of Joseon Dynasty. Results of analysis on the metallic decoration show that the metallic ornament of the end part which is connected to the spade was made by rolling of iron plate and brass plating. The plated part is limited to the ornament of the end part connected to the spade and the plating was not applied to the spade. Brass including 20% zinc was used for the connecting part of guard while brass gilded iron was used for the spade. This suggests that the tone of the connecting part of the guard and the spade was not different for reason of visual harmonization. Potential applied plating method can be amalgam, dippping in molten brass, and brushing but the analysis result suggests that dipping in molten brass method is the most likely accepted method. The brass guard of knife was joined by tin-lead solder. Rivet used to fix the blade was made by pure iron as an optimum material which satisfies flexibility and strength.

DOI : 10.12654/JCS.2015.31.3.12
This study attempted to review the chemical composition of 25 samples of Sangpyeongtongbo having different manufacturing place and period, and then to find the manufacturing method. As a result of chemical composition analysis of Sangpyeongtongbo, main components include Cu, Zn and Pb, and some samples contained Sn and Fe. But, the chemical composition of each Sangpyeongtongbo varied with big differences. When the main content change was examined, Cu and Sn became decreased at the later period, and Zn and Pb had higher contents. The difference in the ingredient content had close relation for the profit of Sangpyeongtongbo. When refined microstructure was observed, 25 kinds of Sangpyeongtongbo had developed different types of microstructure such as dendrite, large grain and grain refinement. But, 25 kinds of Sangpyeongtongbo had no heat treatment processing. And, the types of microstructure were difference, which seems because different microstructure was developed due to the difference of Sn and Fe and cooling speed in Sangpyeongtongbo.
