Seven glass beads from Bupwha-ri site, Yeongdong dated Joseon dynasty were analyzed with SEM/EDS and X-ray diffraction methods. Six samples were classified to potash glass system(
) with HCA(High CaO and
) and high concentration of MgO suggested raw materials to plant ashes. Especially one sample from tomb no. 8 was highly different concentration of
and MgO with others. It was shown that they were different sources of raw materials. Mostly coloring agents of potash glasses were owing to Fe and Cu. One sample was found to lead glass system(PbO-
) with 12% PbO. The content of PbO was differentiated with other lead glasses since we analyzed so far. It needs more study for compositions of lead glasses with regions and ages.

This study focus on the suggestion of standard legend, the process system on making method of deterioration map, the development of crack index (CI), and the evaluation techniques of surface and 3D deterioration rate for stone cultural heritage. The standard legends of deterioration forms were made using a common graphic program after crack, blistering, scaling, break-out, granular disintegration, and perforation were subdivided. The deterioration map improved accuracy and reliability on deterioration range using 3D digital restoration and high resolution photograph mapping technique. Also, quantitative deterioration evaluation of stone cultural heritage was carried out developing the crack index, and the 3D deterioration rate of a break-out part was calculated by virtual restoration modeling. As a quantitative deterioration evaluation of Magoksa Temple stone pagoda based on the results described above, the north face showed high deterioration rate of bursting crack (1.70), hair crack (1.34), scaling (20.2%) and break out (13.0%), and the 3D deterioration rate of first roof stone was 6.7%.

Traditional paste materials and additives for investigation were selected through careful literature survey. We used the immersed glutinous rice flour, soybean as a traditional paste materials and a yellow wax, alum, and lime as additives. The effect of additives on viscosity, pH, adhesive strength, flexibility, antibacterial activities, mildew resistance, and conservation properties were examined. It was found that there was a relationship between the properties(viscosity, pH, and adhesive strength) and the characteristics of additives. Alum increased flexibilty but decreased viscosity, adhesive strength, and pH. Yellow wax deceased flexibilty, viscosity, adhesive strength, and pH. Lime increased flexibilty, viscosity, adhesive strength, and pH. The conservation properties increased by adding all additive. The present work was therefore carried out with the objective of offering the base datum for keeping traditional papers and textiles using traditional paste.

We have suggested effective P-XRF analysis method for pigment painting layer by calculating penetration depth of X-ray. This experiment calculated that X-ray generated from P-XRF was possible penetration until 1.17mm deep in the pigment painting. Based on the experimental results, analysis for eight color pigments on wall paintings in Ssanggyesa Main Hall, most pigments were painted traditional pigments. However pigments on recently restorated wall painting were used synthetic modern pigments.

The aim of this study is to examine the efficiency of ethylsilicate consolidants on sandstone according to its weathering state for an appropriate application to stone cultural heritage in Yeongyang area. Yeongyang area had sandstone and conglomeratic sandstone cultural heritages which needed conservation intervention due to granular disintegration and scaling on their surface. Hyeonri Three-storied Pagoda having typical stone materials in this area was investigated for the analyses of the material and deterioration. And both in-situ and laboratory applications of consolidants were conducted to the outcrop which had the same characteristics of rock type and weathering grade. As a result of the application, it was concluded that Wacker OH 100 and Remmers 300 showed the most appropriate consolidating effect, and Remmers 300 was the most effective to strengthen the loosen and granular-disintegrated surface of the sandstone.
Archaeomagnetic Dating of Hemp Kiln and Lime Kiln

Journal of Conservation Science, volume 27, issue 3, 2011, Pages 291~300
Archaeomagnetic dating method is used to assign a date to the archaeological remains in which burnt soil is found by measuring the changes in terrestrial magnetism with the thermal remanent magnetization retained in burnt soil. This method, in particular, is quite useful to determine an age of the archaeological remains in which no properties are found, which makes it difficult to assigning a date. Hemp kiln and lime kiln fall under remains of these features, and 21 and 5 archaeomagnetic data from both kilns respectively were obtained by measuring the- remanent magnetization in burnt soil samples that are extracted in hemp kilns and lime kilns in the country. The results of archaeomagnetic dating with these data show the age range of the hemp kilns is between the late 10th century A.D. and the middle of the 19th century, and that of the lime kilns is between the early 16th century A.D. and the middle of the 18th century. The factor that the number of data collected from the hemp kilns was comparatively more than those from the lime kilns might affect the result, however corresponding to the fact that hemp had been used for a long period of time, the period of hemp kiln are widely spread over the chronological table. And the archaeomagnetic dating of lime kiln, in view of archaeological periods, is not only in accord with the late Joseon period when the tombs with lime-soil mixture barrier in trend; this is also telling that its width of archaeological period is comparatively narrow.

Epoxy resin has superior durability and adhesive strength and proper physical strength so that it is used to diversity materials for multi-purposes. However epoxy resin is hardly removed after hardening specially once it is applied to artefacts, it is difficult to remove them under re-conservation. This paper is an experimental study on removing epoxy resin applied to iron objects using Nd:YAG laser cleaning system. Tests conducted in this study investigated how increasing laser energy and pulses would give effect on samples. The samples were prepared in a way that epoxy resin, itself pure and one which was mixed with pigment and they were applied to iron coupons and corroded iron coupons respectively. As a result of experiment, pure epoxy resin applied to corroded iron coupons was ablated at high laser energy but epoxy resin applied to iron coupons and mixing with pigment were not ablated but discolored and bubbled due to laser-induced heat generation. Results of FT-IR showed no component alteration of shifted resins and no residues on the surfaces ablated by laser irradiation. From SEM-EDS for removed surfaces, the debris from epoxy resin and melting iron was observed. Therefore, this study demonstrated the possibilities and limitations for laser cleaning to remove epoxy resin from iron objects.

The floral wall of Lee Sang-beom's House and Atelier, which is No. 171 of the Registrated Cultural Heritage was conserved. In addition, materials characteristics and manufacturing technique have revealed through the scientific analysis. As a result of the analysis, samples were divided into three sections; the support layer that is made from block bricks, the paint layer and the cement mortar layer on the paint layer for the reinforcement of the construction. The higher layer lies, the finer grains it has. Furthermore, a little it was generated a small quantity of pores and calcium carbonates (
) generated due to aeration of cement mortar. The patterns of letters, animals and plants pattern were expressed in the paint layer by relief and openwork. The results of qualitative analysis of the pigments of the paint layer were detected components of carbon black (C), Fe oxide (
) and oyster shell white (
, or quicklime). On the other hands, as the conservation of the floral wall, stainless frames were set up for the structural stability, the cement mortar were removed from the surface and the partly damaged and cracked areas were filled with KSE Filler A, B.

Microtexture and components of 7 glass bead fragments excavated from Andong tumulus in Gildu-ri, Goheung have been analyzed to determine the characteristics of their weathered condition as well as chemical compositions. Firstly, status of microtexture shows that there is a large quantity of pollutants which were presumably transferred from the buried environment into the surface and the gap of the cracks. The examination has displayed that there are less amount of alkali metal components such as sodium (Na) and potasium (K) in the gap of the cracks than on the surface. The chemical compositions analysis has confirmed that two samples belongs to potash glass group (
), four to soda glass group (
), and one to the mixed alkali glass group. Chromophoric elements of the glass varies by different colours: blue and navy are cobalt (Co); greenish blue is copper (Cu) and iron (Fe); and light brown is Fe respectively. Such kind of scientific analysis of the excavated glass beads will contribute to the understanding of interchange between various local cultures and arts within the southwest region of Korean Peninsula during the 4th and the 5th centuries.

Cleaning of foreign matter and corrosion products on surface among conservation treatment of iron artifacts is an important part for looking up a original form. The sand blaster is the most popular equipment when it removes the foreign matter and corrosion products on iron artifacts surface. Current foreign matter and corrosion products equipment, which mostly uses, is sand blaster. Glass dust which sprayed from sand blaster is harmful and causing environmental pollution. In order to solve these problems, we investigated the
snow cleaning that use a eco-friendly equipment to apply for cleaning foreign matter and corrosion products on surface of iron artifacts. It examined by using sand blaster and
snow cleaning to aged steel coupon and iron artifacts. In case of aged steel coupon, the result showed that the sand blaster and
snow cleaning methods were similar to the degrees of cleaning foreign matter and corrosion products, through surface roughness, color measurement and SEM.
snow cleaning applied to aged steel coupons weren't worn out the surface in comparison with sand blaster by SEM. When applied to the iron artifacts, power nozzle of the
snow cleaning was an excellent cleaning effect that surface wern't worn out in comparison with sand blaster. And, it showed that internal structure change of metal was no found before and after cleaning by X-ray radiography. Consequently, we confirmed that cleaning of the sand blaster and power nozzle of
snow cleaning were similar to the effect. But, it's very careful to use this method because of high outlet pressure of power nozzle for applying to the iron artifacts. As a result of experiments, it could be found that the cleaning methods should be selected depending on internal state of the artifacts.
