‘Pieta’(1980) by Se Choong Kim required scientific analysis and conservation treatment due to long outdoor exhibitions and paint on surface of bronze sculpture. However, there was a concern that the originality of artwork and ‘moral rights of the artist(the right of integrity)’ could be violated by including conservation treatment methods that were inevitably irreversible, such as removing the old layer and re-patination. Accordingly, the brown color that was mainly used during the artist’s lifetime, was selected as the patination color through collaboration with various stakeholders. As a result of analyzing the making technique of ‘Pieta’, it was found that it was cast in Cu-Zn-Sn-Pb quaternary art bronze. The material, methods, and environment at the time of making artwork were confirmed by comparing the result of scientific analysis of welding, repair, and defects with inerviews with casting engineers. The paint painted on the surface of the bronze sculpture was confirmed as painted twice with metalic paint mixed with polystyrene and copper powder and graphite-based paint. Laser cleaning was applied after a preliminary experiments to stably remove paint, and 95% of the paint layer area was uniformly removed as a result of comparing and analyzing the volume before and after removal through 3D scanning. Brown patina was applied through patination then wax coating to finish.

Gwanghwadang-Wonsam was designated as National Folklore Cultural Heritage No. 52 in 1979, it is in good condition. However, a problem is the attached a phoenix insignia badge that did not exist when it was designated recently. As it became known as the only purple Wonsam artifact with "phoenix insignia", raising the need for its conservation. In this regard, scientific analysis was required to correct misinformation about designated cultural assets and restore the original designated state by analyzing the history of the Gwanghwadang-Wonsam, other relics of the phoenix insignia and its making design patterns. An X-ray fluorescence analysis was used to confirm that the Phoenix insignia's metal threads were titanium-plated silver. Phoenix insignia using titanium-plated gold thread was not identified in Gwanghwadang-Wonsam photographs in 1986, and the TiN-type membrane plating method was used in various industries in the 1990s, which can be estimated to be attached in the early and mid-1990s. Especially, the scientific analysis results from the X-ray fluorescence analysis in this study provide key evidence for conservation processing. This study demonstrates the importance of investigating relics and similar artifacts in the conservation process of inherited relics and as a precedent for restoration that corrects misinformation about designated cultural properties.
