  • This study conducted conservation treatment of a briefcase used by a soldier who fought in the Korean War as a member of the United Nations Forces. The zooid characteristics of its main material, leather, were analyzed in collaboration with the researchers at the National Palace Museum of Korea who have conducted relevant research. A plan for conservation treatment was established based on the results of this analysis. The briefcase was made of leather with a wooden frame. The many densely arranged tiny pores in different patterns on the leather's surface suggests calf leather. The wooden frame and leather had suffered deformation over long years of deterioration and thus required conservation treatment to enhance their structural stability. The conservation treatment began with the removal of contaminants from the exterior and interior of the briefcase. The stiffened leather was softened through humidification, and torn or separated areas were restored using cowhide glue. It is expected that the results of this conservation treatment and analysis of the leather material will serve as useful sources for basic research on leather items as well as wartime and military items.

  • This study references preceding studies to examine the history of paint application techniques using various paints in the past, with the aim to contribute to the long-term preservation of large military cultural heritage assets situated outdoors. To this end, the study compared the findings of preceding research with the findings of an analysis conducted on a H-13 helicopter housed at the War Memorial of Korea. Upon collecting and analyzing samples from three grounded WWII aircraft from above-ground by preceding studies, it was confirmed from each sample that the various chemical properties of chrome ensured the effectiveness of the protective coating. The compound was first tested as a corrosion-inhibiting pigment in the early 1940s and proved its excellent moisture-resistant properties over the course of 80 years, despite the deterioration of the paint layer and long-term exposure to the natural environment. For this reason, it has been widely used as a corrosion inhibitor for aluminum alloys in the aviation industry. In other word, the most widely-used material for preventing corrosion was an organic primer containing chromate. In this study, based on the paint analysis of a H-13 helicopter operated in the Korean War, it was shown that the second layer, consisting of the primer, contains chromium oxide (Cr2O3). In addition, it was estimated that red lead tetraoxide (Pb3O4) was used for the vehicle. Analysis results and data from previous studies can help to confirm the continued effectiveness of corrosion prevention function provided by chromate. Meanwhile, the result of infrared spectroscopy analysis confirmed the use of alkyd resin. In the future, comparisons with a more diverse range of artifacts will allow the identification of changes in the manufacturing technology of paints used to protect alloys from corrosion.
