Go, In Hee ; Jeong, Hye Young ; Park, Ju Hyeon ; Jeong, Sir Lin ; Jo, A Hyeon ;
Journal of Conservation Science, volume 31, issue 4, 2015, Pages 331~339
DOI : 10.12654/JCS.2015.31.4.01
This study were conducted the particle-size analysis on 57 blue pigments to understand the step distribution characteristics of blue pigments made out of Azurite by using Malvern's Mastersizer 2000. As the result, most of the conventional blue pigments in Korea, Japan, and Chinese showed good granularity step separation except for few, and the smaller the particle, the more the Span value increased and the wider the granularity distribution range. On the basis of Friedman and Sanders's Grain size, most of the pigments were sand size to silt size. 72.2% of B-100 was clay size and 2.5% of A-14 was gravel size. Even the same components can differ by the grain size directly affecting the important property such as color formation, oil absorption, specific gravity, usability, etc. so the information about the granularity distribution would be used for basic data to deal with natural pigments.

Lee, Tae Jong ; Oh, Hyeon Jung ; Cho, Ha Jin ; Kim, Sa Dug ;
Journal of Conservation Science, volume 31, issue 4, 2015, Pages 351~360
DOI : 10.12654/JCS.2015.31.4.03
This is the result of the study on the temporary fortifier using sublimation type Consolidate is Cyclododecane to prepare plan for reinforcement of the surface part that can be damaged during the dismantling of stone cultural heritages. To supplement the disadvantages of the existing reinforcement methods using intumescent urethane foam, Cyclododecane was diluted in solvent to reinforce the surface and inside desquamation, and after dismantling the framework, it sublimated by imposing heat of about
. Such method can guarantee the strength needed for reinforcement of the damaged surface with outstanding reversibility of Cyclododecane being entirely sublimated. But, it shows big difference of effect according to the solvent, so it shall be diluted in petroleum ether or heated in a double boiler. Therefore, considering the working conditions at the site, it seems the most appropriate to use petroleum ether double boiler heating method for injection and filling of the desquamation part and temporary reinforcement processing with Cyclododecane diluted in petroleum ether for surface spraying.

DOI : 10.12654/JCS.2015.31.4.04
The experiment attempts to find out the effect of the mixture of the antimicrobial agent and insecticide on metallic material including Silver(99.9%), Copper(99.9%), Lead(99.9%) and Iron(99.5%) by Oddy test. The mixtures of the antimicrobial agent and insecticide were prepared in 60ml; with the standard concentration of 17.5% in B77 Essential oil mixture, one for mixture of concentration of
and insect repellent material; the other for mixture of low concentration and antimicrobial agent(BS-2 and BS-3) material. After Oddy test, we investigated the variation in the surface of the samples by visual inspection, weighing, color measurement and SEM-EDS analysis. The result showed that Lead had the biggest change in the surface, and Copper had the biggest change in the color. In addition, changes in the samples before and after the experiment were found to be greatest at concentration of 19% of Essential oil mixture of the antimicrobial agent and insecticide. Also, B78 Essential oil mixture produce change in samples. It means when the concentration of oil mixture rises, the variation of the samples gets bigger. And, the low concentration of mixture including B77 Essential oil mixture and B78 Essential oil mixture also produce big change in the samples. However, the low concentration of B77 Essential oil mixture that do not contain B78 Essential oil mixture was able to confirm that the change of the surface is not large.

DOI : 10.12654/JCS.2015.31.4.05
This study identified degradation properties by temperature stress with Araldite
AY103-1/HY956 used for ceramics. Tensile and compressive strength of durability increased for 6,480 hours at temperature of
. In stability of external stress and temperature, compressive strength is superior to tensile strength, it requires conservation plans considering strength properties and stress of restoration materials. The tensile shear strength of adhesion properties decreased for 4,320 hours at temperature of
. In ceramics with porosity, environments under isothermal-isohumidity are important because interfacial properties of adherend are concerned with performance variation. Glossiness decreased for 6,480 hours at temperature of
and color difference increased. Gloss stability was superior and color stability was weak, which requires improvement of optical properties. In artifacts on display in museums, there is concern about temperature rise on restoration materials by lighting therefore, it needs to minimize change in physical properties by exposure environments.

Damages of wooden cultural heritages caused by various bio-species have been a trend that is increasing on climate change. The decay and bio-damage caused by microbial organisms or insect species are also known to factors of the shape changes and structural problems of wooden cultural heritages. There are so many phenomenons of damage and weathering in wooden cultural heritage for many years and particularly termite can threaten seriously wooden cultural heritage. We investigated with respect to internal and external environment and termite inhabitation around the wooden cultural heritage in Jeollanam-do, Jeollabuk-do, and Jeju-do. As this investigation results, we confirmed that there were the difference in between resident and non-resident about temperature, humidity, moisture contents of wooden building. Resident building is high temperature but humidity and moisture contents is low and these factors are sources of inhabitation condition change about insects as termites. Now we suggest to carry out in parallel to the target wooden cultural heritage and the surrounding habitat for wooden cultural heritage termite damage investigation. Also with the chemical control methods, we must consider necessary to present eco-friendly control management such as construction of heating facilities, residential status, periodic management.

Malachite and Azurite are the typical copper system pigments which used the mural paintings since ancient times. The mural painting is at risk for damages of the painting layer by atmosphere gas because it is exposed at external environment. In this study, it did experiment about an effect to Malachite and Azurite by environmental pollution gas(
) then analysis and estimate about test for pieces using mural painting colored that two pigments. As a result, Malachite and Azurite were changed on
but not changed
. Especially as the concentration of
is increased, exfoliation of the pigment layer weave remarkably formed pores on the pigment particles on SEM, the phenomenon to be pieces were observed together with smaller particles. In the case of Malachite that were exposed to
gas, new compounds(Rouaite : dicopper (nitrate(V) trihydroxide,
)) was appeared by XRD analysis. Therefore, there had been able to verify the fact that the cause exfoliation and discoloration phenomena accompanied by chemical changes for Malachite and Azurite.

Lee, Eun Woo ; Lee, Jang Jon ; Chae, Mi Hui ; Kim, Eun Ji ;
Journal of Conservation Science, volume 31, issue 4, 2015, Pages 411~427
DOI : 10.12654/JCS.2015.31.4.09
The purpose of the present study is to examine the objects excavated from the archaeological site of the Nogye Village in terms of their relationships with the iron production facilities such as 1ho smithing hearth and 2ho smelting furnace. 32 samples including slags, iron ores, and wall were analyzed to identify the mineralogical and chemical characterization. In addition, in the case of the 1ho smithing hearth slag, differing points of the cross-section were analyzed to examine its formation in depth. The analysis results suggest that the slags from the each site adjacent to the 1ho smithing hearth and 2ho furnace are related to smithing and smelting process respectively. Furthermore, it is possible to draw some conclusions that the aspects of the increased contents of nonferrous elements such as CaO in the slags in comparison with those of the iron ores are due to various factors such as charcoal ash and analytical reasons rather than an addition of CaO as flux.

DOI : 10.12654/JCS.2015.31.4.10
The purpose of this study is to analyse the properties of Seokrok and Noerok that are used for restoration of heritage and arts. Malachite is main constituent mineral for Seokrok and Celadonite is Main component of Noerok. To evaluate the physical properties of pigment, A,B-class Seokrok and heated Seokrok that are sold in market were selected. To compare this results, Noerok sold in Japan were studied. In addition, we studied the pigments of Noerok. The heat treatment had no significant effect on the physical properties, except for the color-difference. The color-difference of Seokrok is larger than that of the Noerok sold in Japan. The
values of Seokrok specimens are horizontal distribution, so it will expand the coloring ranges. The properties that are chromaticity, specific gravity and oil-absorption of Noerok are different from Seokrok. Noerok is suggested that achromatic color because the values of
located near zero. Specific gravity of Noerok is smaller than Seokrok, but oil-absorption is larger twice. Noerok and Amnok, although ingredients are different, it is possible to use alternative because of similar physical characteristics. The result from this study expects to be used as useful referencing data for conservation and restoration of cultural heritage and understanding phenomena of the properties.

Lee, Dong Sik ; Kim, Hyun Yong ;
Journal of Conservation Science, volume 31, issue 4, 2015, Pages 477~488
DOI : 10.12654/JCS.2015.31.4.13
At this, in this study, some tests were conducted to come up with a method to minimize intervention, to reduce the secondary damage to original materials, and to produce remarkable reinforcing effects. The followings show objective standards. The proportion of original material to steel reinforcement bar (the ratio of steel reinforcement bar) needs to be calculated in light of weathering intensity. Second, in the case of partial damage, prosthetic treatment is applied to add new stone materials to original materials. In that case, the ratio of steel reinforcement bar should be calculated based on material that is highly resistant to weathering. With the results of this study, it is possible to suggest conditions that can structurally stabilize stone cultural heritage, according to the weathering area. As a result, the ratio of steel reinforcement bars can be 0.13 to 0.23 in the case of
or less, 0.24 to 0.28 in
or higher, and 0.29 to 0.5 in
or higher. In particular, there is the need to take the coefficient of rupture of stone material and the properties of the steel reinforcement bar into account in cases of calculating the ratio of steel reinforcement bars according to weathering intensity.

The artifacts of Admiral Yi Sun-sin (Treasure No.326) consist of six items with two long swords, a jade decoration, a belt and two peach-shaped cups. In commemoration of the opening of Chungmugong Yi sun-sin Memorial Museum (April 28, 2011), there were conservation treatments for those artifacts at the beginning of 2011. At that time, from the result of non-destructive surface analysis on pigments in blood-colored grooves of the two long swords, it was presumed to be synthetic resin paints. This study shows the accurate identification on pigments which was presumed as synthetic resin paints and its removal. To identify pigments in blood-colored grooves, the optical microscope, scanning electron microscope, Micro-XRF, XRD and FT-IR were used for the analysis. The results turned out that the thickness of
in a single layer was measured. And major components containing Pb and Cr and lead chromium molybdenum oxide were identified and to identify components of adhesives from the analysis by FT-IR, it turned out to be alkyd resin, which can be presumed that they were recently colored with synthetic paints. The synthetic paints easily react with most of the organic solvents. And it is so easy to handle without the effect on metal that it was removed with acetone. While removing synthetic paints, all of paints on it were collected for identifying whether there is traditional pigment but nothing was identified.
