Abstract

Conservation re-treatment of dagger and scabbard in Gyeongju National Museum, which were excavated from Gyerim-ro Tomb No. 14 (Treasure No. 635) was carried out after a wide-scale dissembling in order for publishing a report and holding a special exhibition. The interior shape of the iron dagger which was disclosed by ornament plates was confirmed by X-ray investigation. The results of XRF analysis which was used to analyse compositions of the golden ornament plates reveal that having more than 3% of copper distinguishes it from other Silla gold artifacts. The conservation treatment progressed in a way that surface contaminants were removed and insecure areas were consolidated. The original shape of the iron dagger and scabbard was found after adhering and restoration. With the ornament plates staying on the iron dagger, a stand in acrylic for display and storage was made, which is able to place the dagger and scabbard in the safest way.

국립경주박물관 소장 계림로 14호묘 출토 보물 제635호 보검은 보고서 발간과 특별전시를 위해 전면적인 해체 후 재처리를 실시하였다. X-ray 조사를 통해 장식판에 가려져 있던 내부 철검의 형태를 확인하였다. XRF를 이용한 금제장식판의 성분분석 결과 3%이상의 동(Cu) 함량은 신라 금제품과 차별화되는 특징이다. 보존처리는 표면 이물질을 제거하고 취약 부분을 강화하였고, 철검은 접합·복원 후 본래의 형태를 찾았다. 철검 위에 장식판이 장착된 형태를 유지시켜 최대한 안전한 상태로 안착할 수 있는 아크릴 재질의 전시·보관대를 제작하였다.
