Lee, Myeong Seong ; Kim, Jiyoung ; Lee, Chan Hee ; Kim, Yeong Taek ; Han, Byoung Il ;
Journal of Conservation Science, volume 29, issue 1, 2013, Pages 1~14
DOI : 10.12654/JCS.2013.29.1.01
The Hongjimun Ogansumun (Five-arched floodgates) is composed mainly of biotite granite, pink feldspar granite and granodiorite that are very similar with granitic rocks around the Seoul. Main damage in the floodgates was gray, yellow and predominantly white discoloration on the surface of stone blocks. All floodgates showed more discoloration in the wall than ceiling, and there were growing stalactite on the ceiling. Scientific analyses determined that the white discoloring substrates were mainly calcite. Therefore, conservation treatment was carried out to remove the substrates by using dry cleaning, high pressure cleaning and chemicals. The floodgates have been restored to good state, but it is still significantly necessary to install drainage on the top of the gates.

Chil-sa head-wear excavated in Buksandong of Ulsan is precious relic with historical, cultural, social and artistic values because it shows head-wear shape at the period of Goryeo dynasty with the invaluable worth in the field of Korean traditional costumes. Also, this excavated head-wear provides the empirical information about Goryeo dynasty which has relatively insufficient remains. The purposes of this study are to recover and maintain the original states of the artifacts from various environmental factors and then to preserve the materials from rapid decomposition. As a result, the original shape of the head-wear from Goryeo dynasty can be conserved and through the material and structure analysis it is found out that the head-wear's surface structure is composed of silk(紗) and the ground structure is made by bamboo(竹絲).

This study aims to investigate the film performance by physical properties of glue and gelatin in traditional paint(Dancheong). To do this, homemade, commercial glue and gelatin was selected and evaluated water reaction and weatherproof. The result, the highest gel strength, gelatin was better than acrylic acid ester resin, when compared with hygroscopic property and adhesive property. And that was better than in any others, when compared with water-proofing.

DOI : 10.12654/JCS.2013.29.1.04
The Clay Statues of Donggwanwangmyo Shrine (Treasure No. 142) are highly damaged physical weathering which are crack, exfoliation. Pigment of surface are discolored by chemical weathering like dust. The result of ultrasonic velocity measurement, low velocity zone was measured the lowest part of Woojanggun Statue. Deficiency condition of pigment layer was evaluated quantitatively through infrared Thermography. As a result, exfoliation part was detected at high temperature. Making techniques of the Clay statues were identified by gamma rays, infrared TV, SEM. All Clay Statues were founded on wood base and joints of wood were fixed using thin iron wires. After wood base was twisted a straw rope, it was made by clay. Clay was blended with rice straw to prevention of crack and exfoliation. The upper side of clay layer was coated with Hanji(Korean handmade paper) and cotton in order to isolate the pigment layer.
Study on Aging Characteristics Depending on the Utilized Mordants of Dyed Restoration Paper for Paper Conservation
Jee, Joo-Yeon ; Wi, Koang-Chul ;
Journal of Conservation Science, volume 29, issue 1, 2013, Pages 47~54
DOI : 10.12654/JCS.2013.29.1.05
The following study tests for the effects of mordants on the production of restoration papers during the conservation process of damaged paper artifacts. For this, four different types of synthetic mordants that are being marketed currently (
) were selected to produce samples for measuring variable properties through artificial degradation. The research conducts tests for changes in color, tensile index, and pH level (degree of acidity). The results for changes in color have shown that the value of
mordant sample was the highest, and the tests for tensile index have shown that the strength of dyeing sample was decreased in accordance with the aging time, but Changes according to the mordant was not evident. Finally, the findings for pH level have shown that samples with
have pH levels drop below 6. As a result, the research have concluded that mordants used for dyeing restoration paper were identified to have an affect in the dyeing and aging characteristics of the paper.
Study on Applicability of Passive Infrared Thermography Analysis for Blistering Detection of Stone Cultural Heritage
Jo, Young Hoon ; Lee, Chan Hee ; Yoo, Ji Hyun ;
Journal of Conservation Science, volume 29, issue 1, 2013, Pages 55~67
DOI : 10.12654/JCS.2013.29.1.06
This study focused on analysis condition and application method of the passive infrared thermography according to the direction and time to nondestructively detect the blistering zone of stone cultural heritage. As a result, the passive thermographic images showed different temperature characteristics by time because it sensitively reacts to air temperature, insolation and sunshine direction. In particular, the insolation and sunshine direction, which are periodically changed from 6:00 to 17:00, irregularly made surface temperature. In addition, surface temperature differences were brought on fresh zones and blistering zones except specific time since blistering causes erratic thermal transfer. As a result of examining the detection characteristics of blistering by time, the blistering was well detected between 9:00 and 10:00 when there was rapid increase in air temperature and insolation in all direction except the north. However, this study isn't considered effects of four seasons because it is carried out in autumn, and the passive thermography has difficulty to analyze the quantitative area of blistering zone. Therefore, an additional study for synthetic consideration of the passive thermography analysis about four seasons and quantitative modeling of blistering zone using the active thermography are needed.

This study aims at identifying the variation of physicochemical properties for galena ore in order to use it in understanding of manufacturing techniques in terms of metallurgical method and smelting or refining process for obtaining lead. The ores in the study obtained from the operating mine have been washed and pre-treated for a test. Metallic lead has been extracted by roasting process. The result displays that galena is still in present in the matt despite of exposure to high temperature, over
specific gravity metallic lead has been collected from the refining test of which aim was to remove the remnant galena and a trace of concentrated silver has been identified at the grain boundary. The result suggests that at least one refining process was essential to acquire high purity metallic lead and cupellation had been executed to remove remnant silver.
A Study on Painting Layer Fixative Processing of Mural Paintings of Buddhist Temples in Korea

In the past, European material and method were applied to conservation of Buddhist mural paintings in Korea. At that time, there were inadequate to selection of materials in consideration of porosity and hydrophilicity, therefore insufficiency to assessing their suitability for materials. The treatment result of mural painting are dissatisfied with consolidation of painting layer using synthetic resin. Therefore, it has experimented on applying fixative for reinforcement of painting layer on Buddhist mural painting in order to establish the effects of conservation. In relationship of binder's viscosity, adhesion and penetrating depth, adhesion increased in high-viscosity specimen whereas it decreased in low-viscosity specimen. While the binder's penetrating depths show similar patterns, the surface's response and combination adjacent to painting layer have differences. Animal glue and methyl cellulose (MC) shows excellent performance in their reaction with soil and painting layer. It is estimated that the fixative penetrates deep into soil to produce a stable fixing effect. The viscosity of polyvinyl acetate resin (PVAc) and acrylic resins are low, and thus penetrates well into soil, but they adhere poorly to soil.
