유화 작품 색맞춤용 재료 특성 연구 - 복원용 물감과 아크릴과슈를 중심으로 -

최희진,강대일,Choi, Hee Jin,Kang, Dai Ill 한국문화재보존과학회 2021 보존과학회지 Vol.37 No.5

유화 색맞춤에 사용되는 복원용 물감과 아크릴과슈에 대하여 물감별 특성을 파악하고 자외선 및 흡습건조 열화실험을 통하여 복원재료로서의 내구성을 확인하였다. 4개 제조사에서 제작된 총 20종의 물감을 사용하였으며 분석 결과 동일한 색명의 물감일지라도 제조사별 성분 및 발색 특성 차이가 존재했다. 이는 제조 시 체질, 착색 안료로 사용된 안료의 차이에서 기인한 것으로 판단된다. 열화 후 대부분의 시료에서 𝚫E^* 12.0 이상의 변색이 일어났으며, C사의 Viridian에서는 광택 변화도 관찰되었다. Lemon Yellow에서는 변색과 균열이 모두 관찰되었다. 균열은 복원용 물감인 B사의 것에서 가장 많이 발생했다. 이는 제조 시 사용된 수지의 영향인 것으로 추측되나 향후 정확한 원인 규명을 위해 변수를 통제하여 추가적인 연구가 진행되어야 할 것이다. 연구를 통해 색맞춤용 재료의 색 및 제조사에 따른 물리적 특성 차이가 확인되었으므로, 유화 보존처리자는 색맞춤 시 재료별 변색, 균열, 광택 변화와 같은 물리적 특성을 고려하여 복원재료의 선정 및 사용에 신중해야 할 것이다. In this study, we compare the properties and estimate the durability of five oil colors that are the most popularly used colors in the conservation of oil paintings. A set of these colors was obtained form four manufacturers each, and their properties were analyzed by conducting deterioration experiments. Subsequently, we observed the colors and performed X-ray fluorescence analysis. As a result of colour observation and XRF analysis, it was confirmed that there are the differences according to the pigment types, mixing rations and the manufacturers even for colors having the same product name. The deterioration test indicated differences in the appearance of the colors ; for instance, the color difference was above 12.0 in most of the samples, including restoration color and acrylic gouache. In the case of Lemon Yellow a lot of discoloration and cracking occurred, and difference in gloss was ob served in Viridian of manufacturer C. Most cracks were ob served in the restoration color obtained from manufacturer B and were assumed to be because of the resin used by the manufacturer. Nevertheless, additional research will have to be conducted by controlling variables in order to find out the cause. Through this study, we demonstrated that retouching materials for conservation of oil painting differed in their physical properties according to the color and manufacturer. Therefore a conservator should be mindful during the selection and use of materials for retouching oil paintings.

It has been proved that pollutants stuck on the surface of stone architecture have significant direct and indirect harmful effects on them. Among them some do not look evidently harmful, but they have potentials to ruin stone architecture as time goes on. Since the cultural assets have magnificent meanings as historical aspects, their future states should be considered seriously as well as that of the presence. The past method to get rid of the pollutants from the surface of cultural properties has been changed a lot till the present along with scientific development of technology on this field. Existing method to eliminating pollutants are based on physical and chemical processing, which can make damages on them too. Recently cleansing using LASER has been developed in Europe and proved as effective and relatively less harmful to remove pollutants, and it has been adopted widely. After the success of the way by LASER, there are several trials to adopt the way to our cultural properties which have similar materials. Those showed satisfactory results and studies for developing the securer and more dependable ways to apply. From now on the report will show the effective ways to apply the method using LASER on to the similar materials and different materials as well and discuss about the pros and cons about the method.

The scientific analysis and provenance study of potteries excavated from kiln sites at Jeonla Nam. Buk-do were carried out using XRD,ICP-AES and NAA. We can summarize the following consequence. First, as a result of XRD analysis, it showed that soft potteries consist of quartz, feldspar and clay minerals while hard potteries consist of high temperature crystals such as mullite, tridymite, cristobalite. In case of firing temperature which are determined by crystals using XRD, potteries are composed of quartz, feldspar and clay minerals had very low firing temperature. While potteries having only cristobalite ranged above$1200^{\circ}C$. Second, as a result of correlation analysis using trace element, the selected characteristic elements which was able to distinguish from each kiln site was Ce, Lu, Cs, Sc, Eu. Third, discriminant analytical results showed that kiln site of the Jeonla Namdo were classified into five groups and that of the Jeolna Buk-do into three groups. This suggests that there are no correlations between the raw materials used in each kiln sites.

<P><B>Abstract</B></P> <P>Gamma irradiation can destroy fungi and insects involved in the bio-deterioration of organic cultural heritages. However, this irradiation procedure can alter optical and structural properties of historical pigments used in wooden cultural heritage paintings. The crystal structure and color centers of these paintings must be maintained after application of the irradiation procedure. In this study, we investigated the effects of gamma irradiation on Korean traditional multicolored paintwork (Dancheong) for the preservation of wooden cultural heritages. The main pigments in Korean traditional wooden cultural heritages, <I>Sukganju</I> (Hematite; Fe<SUB>2</SUB>O<SUB>3</SUB>), <I>Jangdan</I> (Minium; Pb<SUB>3</SUB>O<SUB>4</SUB>), <I>Whangyun</I> (Crocoite; PbCrO<SUB>4</SUB>), and <I>Jidang</I> (Rutile; TiO<SUB>2</SUB>), were irradiated by gamma radiation at doses of 1, 5, and 20kGy. After irradiation, changes in Commision Internationale d’Eclairage (CIE) color values (<I>L</I>*, <I>a</I>*, <I>b</I>*) were measured using the color difference meter, and their structural changes were analyzed using X-ray diffraction (XRD) analysis. The slightly change in less than 1 <I>dE</I>* unit by gamma irradiation was observed, and structural changes in the Dancheong were stable after exposure to 20kGy gamma irradiation. In addition, gamma irradiation could be applied to painted wooden cultural properties from the Korean Temple. Based on the color values, gamma irradiation of 20kGy did not affect the Dancheong and stability was maintained for five months. In addition, the fungicidal and insecticidal effect by less than 5kGy gamma irradiation was conformed. Therefore, the optical and structural properties of Dancheong were maintained after gamma irradiation, which suggested that gamma irradiation can be used for the preservation of wooden cultural heritages painted with Dancheong.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Effects of gamma irradiation on the Dancheong were evaluated. </LI> <LI> We confirmed that optical and structural properties of Dancheong were maintained. </LI> <LI> Irradiation can contribute the decontamination for wooden cultural heritages. </LI> <LI> It also can be used for preservation of painted-wooden cultural heritages. </LI> </UL> </P>
