The Wooden Seated Amitabha Buddha Triad and Altarpiece have not been the subjects of definitive species identification and scientific analysis. In this study, visual investigation, portable X-ray fluorescence (p-XRF), species identification, and lacquer layer observations were carried out to determine the original materials and conservation status. Cracks, exfoliation and discoloration were detected during the visual investigation. The p-XRF data indicated that chrome oxide green, malachite, gold, cadmium red, cinnabar, minium, hematite, lead white, ink stick (Carbon), and copper were used for pigments and the coronet accessory. Tilia spp., Abies spp., and Pinus spp. were identified from both the Buddha Triad and Altarpiece. Finally, lacquer layer analyses of the base layer, lacquer layer, orange pigment layer, and gold leaf layer observed modern synthetic pigments likely used in previous conservation. As the Korean Cultural Heritage Charter and the International Charter for the Conservation and Restoration of Monuments and Sites clearly state that objects of cultural heritage must be conserved using their original materials, future conservation of these objects should utilize the data obtained in this study to employ traditional materials. Furthermore, a deterioration map diagnosis can be applied together with the obtained analysis data to understand the conservation status of and inform an appropriate and authentic conservation treatment for the Buddha Triad and Altarpiece.

A C-46 transport aircraft, which can be thought of as a large cultural heritage item from the modern period, was subjected to paint analysis and conservation treatment in preparation for its exhibition. The C-46 is the first aircraft ever dispatched to overseas combat zones by the Korean Air Force and carried out missions during the Vietnam War. The aircraft is mainly made of aluminum and shows signs of corrosion on its surface, including pitting and etching, as well as gray and white powdery attachments. In the analysis of the paint, diatomite(SiO₂·nH₂O) was confirmed in the red paint, titanium dioxide(TiO₂) was identified in the white paint, black iron oxide(Fe₃O₄) was detected in the black paint, and colcothar(Fe₃O₄) mixed with putty was confirmed in the blue paint. Infrared spectroscopy revealed the use of alkyd resin in the paint on the main body and nitrocellulose in the Taegeuk pattern. During the conservation treatment, mechanical cleaning, such as sanding, was conducted to remove paint and varnish from the surface. Corrosion was removed by sanding and cleaning with chemical solvents, and new paints and varnishes were applied. Through the paint analysis and conservation treatment, the aircraft was made available for exhibition in a stable condition.

No one can tell when, exactly, the conservation of potteries & ceramics began, however, according to the documents, it has a long history. Among the materials discovered up to the present, organic adhesives extracted from animals and plants such as bitumen were mainly used and resin, in 19th century, as well. As for inorganic adhesives, clay, lime and plaster were used as well as rivet, as one of mechanical methods. According to the conservation case studies in Korea, lacquer and gilding powdered gold were applied as treatment methods in some ceramics, but, in general, plaster and resins were used widely.

The Geumran-gasa (Kasaya) and Jangsam of the monk Samyeong are historical relics and were designated as object No.29, a Buddhist costume of the Joseon Dynasty, by the National Folklore Cultural Heritage, in 1973. In 1984, after being treated for the purposes of washing and preserving the shape of the garments, the object was kept in the Temple Museum of Pyochungsa, as their holding institution. However, regular inspection conducted by the Cultural Heritage Administration in 2013 determined the need for a re-treatment. The Geumran-gasa had been originally made with 25 strips, but it had been separated into two parts and many pieces were lost. A part of the collar in the Jangsam was lost as well. Therefore, both relics needed to be restored. The re-treatment process involved pre-investigation, washing, reinforcement fabric dyeing, restoration, and fumigation. In particular, we focused on reinforcing the damaged parts and restoring the missing parts by applying advanced materials and methods in order to restore the original form as much as possible. This conservation is the result of the re-treatment of the cultural properties by replacing the old material used in past treatments and applying advanced methods under the basic principle of reversibility in conservation treatment.

For safe conservation treatment of damaged accessory relics that were unearthed, the quality of the material should be accurately identified through a nondestructive analysis and failure analysis. This study provides the basic conservational scientific data regarding material analyses and conservation treatment that were conducted for 11 relics, including amber and agate that were discovered during the repair of Geumsansa Temple's Hall of Maitreya Buddha and Left Attendant Buddhas in June 2008. An ultraviolet analysis, SEM-EDS analysis and FT-IR microscope analysis revealed that the physical and chemical characteristics of the 11 relics are the same as those of amber. It is inferred that the cracks and exfoliation of the surface of most amber relics is attributable to darkening of the color due to C=C bond oxidation. It is also assumed that cracks and exfoliation occurred from the weathered layer on the amber surface. As such, it is appropriate to engage in conservation treatment of the damaged amber relics by using $Paraloid^{(R)}$ B67 reinforcing agent that is diluted in nonpolar solvent. The greatest care is needed for future handling of organic artifacts.

The bronze bowl with lid excavated from Eunnyeongchong Tumulus in Gyeongju had been united in the past and then damaged. We removed deteriorated adhesive and other impurities from it and reunited it. Some fragments of the artifact has been lost; in particular, only half of the whole main body remains. Therefore, it needed restoration treatment for exhibition and conservation. The lid, relatively much part of which remains, was treated with the method that could easily detach the restored part; the main body with much restored part was united using epoxy resin so that the restored part could well bear the weight of the artifact.
