The metal corrosion caused by museum indoor air pollutants
Kang, Dai-Ill ;
Journal of Conservation Science, volume 22, 2008, Pages 5~14
The effect of air pollutants coming from internal museum materials such as wood-based products and cements on metal corrosion have been investigated. The Oddy test and the Chamber test was employed as a corrosion test. The metal pieces after the Oddy test had different corrosion types caused by the internal museum materials. The most effective wood based product was 18T HS(E0) and 9mm plywood(F0,E0). Iron(Fe) and copper(Cu) also bronze of the Chamber test had corrosion caused by Formic acid, Acetic acid, and Acetaldehyde. The packing materials in high humidity had caused more corrosion on the surface of the metal pieces than in low humidity.

Journal of Conservation Science, volume 22, 2008, Pages 15~30
The roof tiles from the tomb in Baekje Kingdom of the Danjiri site in Gongju, Korea were studied for the production techniques and raw material provenance based on archaeometric characteristics. The roof tiles had traditional shapes of Baekje Kingdom, which show flow texture on the surfaces and sections with the roof tiles of hard or soft-type. These roof tiles were locally produced, using refining soils according to mineralogical and geochemical characteristics. Also roof tiles were divided to 2 groups by firing temperature and physical properties. One of them had soft with porous texture and fired probably about 700 to
. The other had hard with vitrified texture and probably fired about 940 to
. Buried for long time and used as a tomb, roof tiles had experienced chemical alteration due to the enrichments of trace elements abundant in human tissues.

A stone cultural heritage often lacks design drawing and detailed geometric informations, thus it becomes more difficult to conservation and restoration. Even though there is active database of detail shape information and numerical measurement for stone monuments, most of the data is in hard-to-utilize two-dimensional images. The new technology developed to overcome this problem is three-dimensional image scanning system. The multi-storied stone pagoda of the Daewonsa temple was analysed with 3D scanning image data then survey map with orientation displacement was evaluated. The difference of each side became apparent with the members of the stone properties was measured, also horizontal and vertical displacement occurred. Horizontal displacement occurred in increasing severity from left to right and from body section to upper part. The 8th roof stones are leaning toward northwest direction due to lateral displacement. The evaluation and measurement of displacement could cause a little errors due to the characteristics uneven surface of stone monuments, computer program and mistakes from the researcher. In future, more precise measurement and stability studies should be done to suggest that accurate data for conservation and understanding of damage condition can be provided.

This study is investigated the characteristics and the comparison on blackware and whiteware at Gilmyeong-ri kilns, located Poncheon-si, Geonggi province at AD 19c using scientific analysis. It is measured by scientific analysis classified as microstructure observation, physical methods which involved chromaticity, specific gravity, absorption ratio and porosity, and chemical analysis of components of body and glaze. As a result, a particle and a pore of body surface appeared differently by the degree of vitrification. In glaze, Blackware have better on good vitrification than whiteware in the microstructure observation. The physical characteristics of chromaticity, specific gravity, absorption ratio and porosity differed according to degree of vitrification rather than porcelain types. In composition, body of blackware have higher ratio of
than of whiteware. Also glaze of blackware have higher ratio of
, and lower ratio of
than whiteware. Especially, blackware have higher ratio in the composition of CaO and
by which ash is used or not.

Cho, Hyun-kyung ; Cho, Nam-Chul ;
Journal of Conservation Science, volume 22, 2008, Pages 61~76
We examined characterizations of Paraloid B72 films when it dissolved in four different solvents-acetone, MEK, toluene and xylene. The surface before and after coating were observed by optical microscope and AFM. Thickness and contact angle of films was measured and surface energy was calculated for grasping properties of films. We also tested adhesive strength of films by scratch tester and durability of films by performing yellowing test. The result was that xylene has better coating property than other solvents. Because 10% Paraloid B72 in xylene film is even, non-mottled, thin, stabilized in yellowish and has proper hydrophobic, we confirmed xylene is good solvent for bronze artifact conservation. However, other tests will need for finding appropriate concentration of Paraloid B72.

The pre-treatment for conservation must be needed for the exhumed historic sites. So, the study of conservation and restoration of historical sites has progressed favorably with using various polymers for solving upper problems. The problems which should be essentially solved for conservation of the exhumed historic sites are, however, using reinforcing agents that don't impair their original forms and sorting reinforcing agents on the lines of the historic sites' soil. These agents should be able to use without the effect of outer environments like marsh, winter time or temperature. In this work, we synthesized Epoxy resin and Epoxy hardener for the restoration of historical sites. These products have very good tension strength and adhesion strength and various physical properties that the users want. Particularly, these epoxy with high viscosity have good separation of between Epoxy final product and Urethane pre-surface.
Surface Treatments of Bronze Mirrors Excavated from Korean Peninsula

Journal of Conservation Science, volume 22, 2008, Pages 87~98
Microstructures and chemical compositions of 24 bronze mirrors recovered from the Korean peninsula were examined using the scanning electron microscope equipped with the energy dispersive spectrometer in an effort to characterize the treatments applied on their surface. Their provenance and chronology are mostly unspecified except for two objects from a Koryo burial site. In antiquity the surface of bronze mirrors was frequently finished by mere polishing when their tin content was high enough to guarantee the required reflectivity. In many cases, however, their surface was given a special treatment. The most typical treatment was to coat the surface with tin in two different processes referred to as wipe-tinning and amalgam-tinning. In wipe-tinning only tin was used, but in amalgam-tinning tin and mercury were used together. The surface was often coated with mercury in a process known as mercury-polishing. The present mirrors showed that all these techniques were in fact practiced, not only on the reflective surface but, in some cases, on the decorative surface. The detection of mercury played a crucial role in the assessment of a specific technique applied in each mirror. Mercury often remained in the substrate in the form of sulfide and thereby allowed the method of surface treatment to be estimated even when the coated layer was completely lost. The future study is expected to uncover the regional and temporal variation of the surface treatments to the better understanding of bronze mirrors with respect to provenance and chronology.

Han, Kyeong-Soon ; Lim, Kwon-Woong ;
Journal of Conservation Science, volume 22, 2008, Pages 99~108
This research aimed to provide a scientific methodology for removing white and black/brown coloured stains on the wall paintings of tombs of Jinpari No 1 and No 4. in the Democratic People's Republic of Korea. For the analysis of chemical composition of stains of the samples from the wall paintings, a microscope and SEM/EDX were used. The analysis confirmed that the fomula of white coloured stains should be
and the black/brown coloured stains should be
with soil deposition. Because of the difficulties of testing several cleaning solutions on sample patches of large area of the painting, the author considered a risk-free cleaning solution as being the most appropriate one, with Ammonium bicarbonate and Anion exchange resin showing satisfactory cleaning effect without visible side effects. For the removal of dense layer of stains, the research suggested that physical cleaning should be followed by applying a cleaning solution.

Understanding the whole knowledge of ceramics is essential for a person in charge of conservation of ceramics since their methods of manufacturing or materialistic features have very close relationship with their damaging process. Also, various executions of repair and restoration dealing with any damage in use have to be looked into. The information attained through those studies finds damaging causes of ceramics, which becomes a critical element when choosing a proper conservation treatment method and utilizes as indispensable data for permanent preservation. As part of scrutinizing materials of repair and restoration, this study examines the purpose, date, and the constituents of the materials used in metal bound rims adhered to the brim of ceramics. Among the subjected ceramics, the metal bound rims possible to scientific analysis were gone through element analyses with Portable
-XRF Spectrometer and SEM-EDS while the ingredients of the ceramics difficult to analyze were inferred by eye inspection of exhibition catalogues. The results of this study confirm that metal bound rims consisted of diverse materials were adhered to the brim of ceramics.

Do, Jin-Young ; Lim, Kwon-Woong ;
Journal of Conservation Science, volume 22, 2008, Pages 121~134
The mechanism of stone exfoliation and its cause in relation to chemical weathering by soluble salt were studied. Chemical, mineralogical and physical analysis was performed in exfoliation samples from stone monuments. The representative salt is gypsum in the exfoliation samples. In order to understand the salt reaction, stone samples(tuff and granite) were treated with two type of the salt, gypsum and sodium sulfate, which have different solubility. The capillary water uptakes are slight increased in impregnated with Na2SO4 and weathering simulation of two rock types. It means that the rock is deteriorated in the near of the surface by
bring out the thicker exfoliation than
because it is penetrated into the deeper zone and amount of accumulated salt is more abundant in the inner part than in the near of the surface. The exfoliation was formed in the tuff by salt treatment and 30cycle of weathering simulation, but there are not significant symptoms of exfoliation in the granite by same condition. This result was caused by the different capillary water uptakes and porosity of the rocks. In the tuff, salt solutions are penetrated into the inner part due to its high capillary water uptakes and porosity but the granite, which has low value relatively, can be formed thinner exfoliation.
