이성산성 출토 목제칠기 보존

The wooden lacquer wares, which had excavated from the water reservoir in the Isong Sansung Fortress, were applied with vacuum freeze drying method and treated, after they had been substituted with tbutanol, and treated with PEG-pretreatment. The manufacturing technique, which had not been investigated in the past, was examined through the investigation of the wood and the lacquer used for wooden lacquer wares, and the pieces of the lacquer wares, which had been stored for a long time, were restored for the exhibition and conservation. As the result, the wooden lacquer wares were manufactured, using black alder belonging to the group of Alnus, and the lacquer was painted on the bottom-layer by mixing the powdered soil and lacquer, and it was confirmed that the lacquer mixed with the black pigment and the pure lacquer had been painted alternatively over 2 times, and that the wooden lacquer ware had been manufactured through total 5 times of being painted.

이성산성 저수지안에서 출토된 목제칠기는 이미 국립문화재연구소에서 t-부탄올로 치환하여 PEG함침처리 후 진공동결건조법을 적용하여 보존처리되었다. 당시 이루어지지 않은 목제칠기의 수종 및 칠조사를 통해 칠기의 제작기법을 규명하고 여러개의 편으로 보관되어 온 칠기편을 전시 및 보관을 위하여 원형복원하였다. 그 결과 오리나무속(Alnus)중(中) 오리나무류를 사용하여 목제칠기를 제작하였으며 칠은 밑층에 토분과 칠을 혼합하여 칠하였고 칠에 흑색안료를 섞은 흑색칠과 순수한 칠을 2번 교대로 칠하여 총 5회 칠을 올려 제작한 것으로 확인되었다.
