  • More than 200 objects selected for the newly-opened Kimhae National Museum were treated for conservation. The objects which represent ancient Kaya culture, were mainly composed of metallic such as gilt bronze, silver, copper alloy and iron. The corrosion products on gilt bronze and copper alloy objects were preserved or removed according to their stability. Minimum treatment was done for preserving the original state of the objects. For silver objects and iron objects with silver-plate decorations, silver surfaces were revealed after treatment of corrosion products and treatments to prevent corrosion of silver and iron were done emphatically. For iron objects, which were stabilized, the original shape of objects was restored and acrylic coating was applied to prevent further corrosion. For the objects which were being corroded, 2-step de-chloride treatments were undertaken. The first step was immersing the objects in a solution of 0.3M sodium hydroxide and the second was the pressure de-chloride treatment using borax-distilled water. The main purpose of those treatments was to get rid of the causes of corrosion. Besides, conservation treatments for potteries, making of special mounting board for exhibition and amendment of various modeling were done too.

  • Field experiments for Conservation damage on selected spots were carried out prior to direct conservation treatments for Bangudae Petroglyphs in Ulsan. It was found that there is a big difference in treatment effects according to the treatment technique and application rather than on the treatment material use. Based on the results of this study, a plan for the conservation treatment of Bangudae Petroglyphs will be suggested by providing new materials and application techniques for cracks, adhesive application and consolidation by conducting artificial weathering tests and continued monitoring.

  • For the conservation of wooden coffin from King Muryeong's Tomb we examined weight change, shrinkage rate, color changes, and permeation expansion according to the permeation pretreatment chemicals by producing experimental samples with similar physical properties. The result shows Dammar 2 %(in xylene) as the most excellent treatment for protecting deformation by contraction and strengthening materials which are also maintaining its original colors of wood. Therefore, we could get strengthening conservation treatments of dried wooden coffin materials by using Dammar.

  • Conservation treatments were done for the gilt bronze saddle accessory excavated from Tomb No. 89 in Kyo-dong, Changnyong in Japanese rule period. The saddle accessory, broken into numerous pieces, was mixed with other remains. Principal aims of conservation treatments were to recover original shape of object and stabilize its material. In the process of treatments manufacturing technique of the remain was examined minutely. Thick layers of corrosion substances were peeled off and numerous pieces were pasted together to restore the original shape. And then the saddle accessory was mounted on an acrylic board to be handled and exhibited safely. In this process, it was confirmed that various ancient techniques of metalic crafts such as amalgam gilding, riveting, piercing, line engraving, stamping, chasing etc. had been used to make the saddle accessory.

  • We carried out the effect verification of conservation treatment focusing on basement rock of alkali granite at the Yukjonbul (two-pairs of Buddha Triads) carved on rock cliff of Samneung valley in Namsan mountain of Gyeongju. The conservation treatments were used to ethylsilicate-type rock consolidant and epoxy-type resin. It is treatment method that the epoxy-type resin have been applied one time into the exfoliation area, after rock consolidation treatment have been worked for three times. As the result of measuring ultrasonic velocity, P-wave velocity of the exfoliation area was relatively increased after applied the conservation treatments. The ultrasonic velocity of all area was increased as 27.8%. This result has been proved with consolidation effects by consolidant and filler for stone cultural heritages. The treatment method should be worked about three time to consolidate sufficiently for rocks.

  • Studies were conducted on manufacturing techniques by applying microscopy and conservation treatments on the annals of Joseon dynasty storage box at the National Museum of Korea. The results revealed that lime tree wood(Tilla spp.) was used to make the annals of Joseon dynasty storage box. Lacquering techniques were used to coat the box with a layer of lacquer and bone ash and then cover it with traditional Korean paper. After being covered with traditional Korean paper, more layers were applied in the following sequence: mud ashes, black lacquer, pure lacquer, and black lacquer. Before conservation treatments, some components and lacquer layers were missing in addition wood joint were loose. Therefore, conservation and restoration should be conducted based on the identified wood and by observing the shape of the remaining components.

  • This article is an introduction to : ICCROM PAPERCONSERVATION COURSE 1993" which I participated in, from July 28th 1993 to September 24th. The program was divided into two major sections. The first part deal with scienctific principles of paper conservation, covering structure and composition of paper and related materials, causes of deterioration and guidelines for preservation. It include chemistry for paper conservators and the history and technology of papermaking. Second part of the course emphasize practical conservation ; participants actually work together with specialists. Two weeks are dedicated to the Western approach to paper conservation. A selection of recent conservation treatments are discussed methodologically, demonstrated and performed. The same amount of time are devorted to a seminar on the conservation of fareastern paper objects. The aim is to exporse participants to different approrches and methodologies in paper consevation, to compare and discuss various tendencies and to learn lessons from other experiences that are applicable to one's own work.

  • General aspects of the scientific conservation of buried cultural properties were reviewed. Thus, instrumental survey of buried cultural properties, scientific conservation of excavated artifacts, (especially. the first aid treatments of the excavated artifacts at the excavation site) and scientific conservation of the excavated remains (conservation at the site or at transition sites) were treated in outline.

  • Precise scientific-diagnosis for preserving stone cultural properties has been well-advanced, but research on proper methods for conservation, restoration and repair is still in early stage. Accordingly it is quite difficult to establish conservation treatment methods compatible to unique characteristics and environments of each cultural property. We tried to select most compatible conservation materials through thorough assessment of conservation materials in current use. This research is focused on conservation and restoration materials except cleaner, which are used as adhesive, filler, repellent and consolidant. Conservation treatments for stone cultural properties were first tested in 1960's and have been carried out by various methods under relevant organizations and conservation treatment companies since. We investigated present status of conservation materials being used for cultural properties. Based on these data, we will look through types and properties of the conservation materials to figure out existing problems. Among many kinds of resins, the ratio of conservation materials used in cultural properties is very low. Therefore, new conservation materials equipped with proved long-term stability should be developed as soon as possible.

  • 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.
