  • The manufacturing technique was studied through the structure and material characteristics of the walls and the painting layers of the Avalokitesvara Bodhisattva mural of Geungnakjeon Hall, Daewonsa Temple. The mural is painted and connected to the earthen wall and the Junggit, and the wall is composed of wooden laths as a frame, the first and middle layers, the finishing layer, and the painting layer. The first layer, middle layer, and finishing layer constituting the wall were made by mixing weathered soil and sand. It was confirmed that the first layer had a high content of loess below silt, and the finishing layer had a high content of fine-sand and very fine sand. For the painting layer, a ground layer was prepared using soil-based mineral pigments, and lead white, white clay, atacamite, minium, and cinnabar (or vermilion) pigments were used on top of it. The Avalokitesvara Bodhisattva mural was confirmed to belong to a category similar to the soil-made buddhist mural paintings of Joseon Dynasty. However, it shows characteristics such as a high content of fine sand in the finishing layer and overlapping over other colors. Such material and structural characteristics can constitute important information for future mural conservation status diagnoses and conservation treatment plans.

  • The buddhistic painting of Song-Kwang temple in Seungjoo-gun, Chonnam, Korea is not known in chronicle, but it could be estimated to works in the early 19th century through it's remaining records and qualities of materials. And it was analysed the qualities of materials consisting of pigment layer, silken-ground layer and support layer in order to preserve buddhistic painting, made back-adherent paper of the support layer proper to it, tested its compatibility, and then concluded as follows. 1. The section structures of buddhistic painting is consisted of the pigment layer, silken-ground layer of silk and the support layer of Korean hand made paper, it could be recognized that buddhistic painting in 19th century was basically composed of the pigment layer, the silken-ground layer and the support layer. Moreover the pigment layer and the silken-ground layer got adhered with glue, and sheets of support layers got back adhered with paste. 2. The support layer of buddhistic painting consisted of 5 layers and two kinds of paper were used for them. The first and second layers were composed of Korean hand made paper made of pure paper mulberry bast fibers, and the rest of them of paper that paper mulberry bast fibers were mixed into recycled hemp fibers. Though it is difficult to assert without the security of more data, finding out the then situation through the qualities of materials, it was presumed that the society in 19th century was suffered from economical difficulties and the operation of the paper industry of temples was rather difficult and so low-qualitative recycled hemp fibers might used for back-adherent paper. 3. Considering tension between silken-ground layers and support layers of this materials, newly made back-adherent paper was used for repair, and then I could conform that it was proper to back-adherent paper for repair.

  • The exterior of Korean traditional wooden buildings have been painted with Danchung of painting method using glue and pigments. However because of losing traditional techniques and materials through the period of colonization and industrialization, many problems are occurring today. Especially after several years from painting, occurrence of scalings and flakings in painting layer is a serious problem. To improve weathering resistance of painting layer caused by stress from the difference of swelling and shrinkage between painting layer and wood plate, was examined by weathering tests. The stress is due to the hydrophilic property of wood, mechanical properties(tensile property and stress relaxation) of painting layer, and priming methods by various binders such as glue, acrylic emulsion(Primal AC-3444), acrylic resin(Paraloid B-72). Because stress relaxation of acrylic emulsion of which glasf transition temperature is below room temperature$(7^{\circ}C)$ is high, painting layers with acrylic emulsion generate no scalings and flakings and are in the most durable state in all weathering tests. Priming method which starts from low concentration to high concentration, is more effective to improve durability than other priming methods.

  • This study examined the production technique of bracket murals in Daeungjeon Hall, Gaeamsa Temple by conducting a analysis of their wall structure, material characteristics, and painting layers. Wall was a single-branch structure with support layer, middle layer, finishing layer, and painting layer. The support layer, middle layer and finishing layer, were produced by mixing sand (quartz, feldspars etc.), and loess. The ratio of above medium sand to below fine sand was approximately 0.7 : 9.3 in the support layer, 4 : 6 in the middle layer and 6 : 4 in the finishing layer, which had a more percentage of above medium sand than the support layer. The analysis of the painting layer showed that natural soil pigment was used to establish a relatively ground layer of up to 50 ㎛, and pigments such as Lead sulfate, atacamite and mercury sulfide were painted on top of the layer. This study's results confirmed that the bracket mural paintings in Gaeamsa Temple are within the category of the production style of murals during the Joseon period. However, the points that the middle layer was formed several times, the significant difference in particle size distribution between the wall, and the absence of chopped straw in the support layer are a feature of bracket mural paintings in Gaeamsa Temple. These properties of murals as material and structure may be viewed for correlation with the degree of damage to wall structure of mural painting and would serve as an important reference to diagnosis the conservation conditions of murals or prepare conservation treatments.

  • The manufacturing techniques were studied by investigating a precise analysis on wall structure, features of materials and the painting layer of the bracket mural paintings at Daeungbojeon Hall in Naesosa temple. The wall frame is a single-branch structure, and The mural paintings are composed of 3 layers which are a support layer, a finishing layer and a painting layer. The support layer and the finishing layer are an earth wall that sand and clay such as Quartz, Feldspar, and etc. are mixed. The support and the finishing layers have a combination of medium particle sand and smaller than fine particle sand in the approximate ratios of 0.8:9.2 and 6:4, respectively. Therefore, the aforementioned ratio of sand with medium or large particles is relatively higher in the finishing layer than the support layer. As a result of a precise analysis on the painting layer, it has a relatively thick ground layer for painting which is maximum $456.15{\mu}m$ by using Celadonite or Glauconite and the paintings were colored by using pigments such as Atacamite, Kaolinite or Halloysite, Oxidized steel, and etc. on it. The manufacturing style and the painting techniques of an earth wall are included in the category of the Joseon Dynasty style that have been studied up to now, but the facts that the finishing layer has a high content of sand and a middle layer and chopped straw have not been identified. These are remarkable points in terms of structure and materials, and can be crucial in the evaluation of the state of conservation of mural paintings or preparation of a conservation plan.

  • 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.

  • The pigments composition and structure of the mural painting at Pongjongsa Kuknakjon is discussed. The structure of inner wall is consisited of Paint layer, Ground divided two layers of yellow and white pigments, Support. In case of outer wall, it is consisted of Paint layer, Ground divided three layers of yellow and green pigments, a layer mixed green pigments and paint layer, Support. As a result of compositon analysis of mural painting pigments at Pongjongsa Kuknakjon using Micro-area X-ray diffraction system, the red pigment on inner wall is consisted of Heamatite($Fe_2O_3$), Magnetite($Fe_3O_4$)of deep black pigment, and Chalcocite($Cu_2S$) of light black pigment. The white pigment on outer wall is consisted of Anglesite($PbSO_4$) and Atacamite($Cu_2CI(OH)_3$) of green pigment. We found out that natural pigments painted in the mural painting at Pongjongsa Kuknakjon has kept up its own color for a long time due to using the natural pigment not to artificial synthetic pigment.

  • Painting is well regarded as a stratified structure by the conservators and restorers. Hence, the scientific methods have been developed for the study of the interal layer of paintings. Examples of such methods are X-ray, infra-red, and ultra-violet photography. A more direct method is to look at the painting in cross section under the microscope and to analyze pigments using an electron probe X-ray micro analyzer(EPMA).In this research, I study and analyze twenty two Korean paintings of self-portraits including the first oil painting of Hui Dong Koh's self-portrait stored in the museum of Tokyo National University of Fine Arts and Music, employing these scientific techniques. The small fragments taken from the ground layers of the early oil paintings(1915∼1942)are analyzed using the EPMA. According to their main materials, the ground layers can be classified into five types ; 1. Lead white layer and double layer of calcium carbonate and lead white, 2. Zinc white with some mixiture of lead white, 3.Titanium white with some barium white, 4. Barium white, 5.Double layer of titanium white and zinc white.

  • The first priority we face in the conservation of wall paintings, is the conservation of painting layer. The 'painting layer' is sometimes called the pigment layer, and refers to the painted surface. For the consolidation of this painting layer we use 'fixative'. Fixative is a common adhesive which has been used in various field and conservators have made up for the weak points in the consolidation of wall paintings. In my thesis, I will summarise the range of use, standards of selection, and results of research on the use of fixative in the conservation of European paintings. In addition, I will describe various kinds of our traditional fixatives. As synthetic resins have proved that it is not ideal as a fixative for wall painting, conservators have studied to find an alternative. Same as European conservators, Asian scientists has researched to find alternative fixative which is more suitable to the wall paintings in Asia based on their traditional techniques and materials. Therefore, 1 have studied to find an adequate fixative for our own wall paintings and I could conclude that we can consider traditional fixative which is made of 'seaweeds' as an alternative and it is very important to proceed research and experiment on this material.

  • The painting layer of Payathonzu temple mural paintings in the ruins of Bagan Myanmar has been damaged due to various reasons. In this study, the applicability of Neem resin, a traditional Myanmar adhesive, as a fixative on the painting layer was examined. Cow glue and Paraloid B-72 were selected as fixatives in the comparison group, and pseudo-specimens with conditions similar to the original mural paintings were produced to examine the changes before and after applying the fixatives and according to the deterioration experiments. As a result of conducting the experiments and comparing the fixatives, it was found that changes on the surface such as smudge, yellowing and gloss are greater with the application of higher concentration of Neem resin than with other fixatives. However, such changes were relatively small under the condition of 4% concentration. It was also confirmed that chromaticity and glossiness vary greatly between before- and after-application of the fixatives but that such discrepancies tend to decrease at 4% concentration compared to other concentrations. As for fixation strength, it was found that the fixation capacity of Neem resin on the base and painting layers is overall higher than other fixatives as the concentration is increased. Therefore, the applicability of 4% concentration of Neem resin as a fixative on the painting layer was confirmed considering the low surface changes according to environmental factors, low color discrepancy and glossiness, and characteristics of excellent fixation strength. It is believed that the findings of this study could be used as basic data for the preservation of Payathonzu temple mural paintings in the future.
