This study presents an investigation into the conservation process of an iron dagger and scabbard, which are a lacquered scabbard and a dagger inserted in it, excavated in the Daho-ri relic of Changwon by Gimhae National Museum. The bronze dagger whose condition was poor due to corrosion was coated with Incralac, an intensifier, to reveal the surface patterns through a microscope. The lacquered scabbard was removed of foreign substances on the surface and coated with HPC 2%(in water) to protect the film. Applied onto the surface from which foreign substances were removed was Caparol Binder 5%(in water) two to three times to form a protective film and then faced with Korean paper. Once it was fixed in a polyurethane foam in a stable manner, it was turned over to receive the same process on the back. Three layers of Korean paper were attached to the back of the scabbard to support the thin artifact. HPC 2%(in water), which was applied to the scabbard, was also applied to the iron dagger inside for cementing effect. After all the processes were completed, the artifact was put in a transparent acrylic box for future display.

Twelve bronze artifacts and silver earring from Kimhae Yangdong-ri Site were treated by B.T.A(Benzotriazole) for the stabilization of copper alloys and impregnated with Incralac for consolidation. Bronze artifacts were analyzed qualitatively by X-rayfluorescence. It was found that elemental composition of bronze artifacts were Cu-Sn-Pbsystem wint some impurities such as Bi, As, Fem Sb, and Ag.

The flower type ornament of the gilt bronze palace-type sarira reliquary among those sarira reliquaries of the East Pagoda at the Gameunssa Temple Site, which is the Treasure No. 1359 owned by the National Museum of Korea, was separated from the sarira reliquary in November 2010, thus conducting conservation treatments to be done on two items including the gilt bronze palace-type sarira reliquary during the period of March-October 2011. Those conservation treatments were carried out by following the process of removing the coated areas having excessive gross and bubbles, re-coating with Incralac, and then strengthening both the cracked areas and the separated flower-type ornaments with woven glass fiber after rejoining. For those areas where removal of gloss and bubbles at the coating and adhesive areas was not possible, the gloss and bubbles were made less perceivable through matting treatment and coloring.

The purpose of this paper is to select the suitable resin as changed in environmental and ingredients, in the conservation of metallic objects. Disposal way of metallic objects were used to various resin and grease which will must be well selected in the nature of relics. The contents of this report are summed up as follows ; The resins of Incralac, Ruscoat, wash primer, Amerlock-400 wrer coated on the slice of ironware (5% saltspray test on the view of nature & Adherence). After the coating, add increasing speed to a corrosion rate, and then the adherence of resins were tested. In this study corrosion test, 0.10-0.25% Amerlock-400 jis proved to be a rare one of corrosion rate and 1.0-2.5% Wash primer is found to be a plenty one of corrosion area.

The gold crown unearthed from the ancient tombs at Imdang-dong, Kyongsan-gun, Kyongsangbuk-do was in a state of severe corrosion that its original pattern couldn't be identified. Therefore, for the conservation of the relics, the following methods are employed :1. With 10% formic acid are used for the elimination of the bronze-rust and then plated them with gold.2. As a rust-proof treatment, 1% Benzotriazole is used for stem corrosion as well3. For protection and reinforcement of the surface of the relics, 30% incralac agentsare used.4. Pieces of fragments are bonded together by cyanoacrylate and on the backside are coated partially with Araldite for the reinforcement of the glass-wool.5. Silica-gels are kept into the acryl box for perfect maintenance.
