The artifacts of Admiral Yi Sun-sin (Treasure No.326) consist of six items with two long swords, a jade decoration, a belt and two peach-shaped cups. In commemoration of the opening of Chungmugong Yi sun-sin Memorial Museum (April 28, 2011), there were conservation treatments for those artifacts at the beginning of 2011. At that time, from the result of non-destructive surface analysis on pigments in blood-colored grooves of the two long swords, it was presumed to be synthetic resin paints. This study shows the accurate identification on pigments which was presumed as synthetic resin paints and its removal. To identify pigments in blood-colored grooves, the optical microscope, scanning electron microscope, Micro-XRF, XRD and FT-IR were used for the analysis. The results turned out that the thickness of in a single layer was measured. And major components containing Pb and Cr and lead chromium molybdenum oxide were identified and to identify components of adhesives from the analysis by FT-IR, it turned out to be alkyd resin, which can be presumed that they were recently colored with synthetic paints. The synthetic paints easily react with most of the organic solvents. And it is so easy to handle without the effect on metal that it was removed with acetone. While removing synthetic paints, all of paints on it were collected for identifying whether there is traditional pigment but nothing was identified.
