초록
Scientific analysis and conservation treatment were conducted on a wooden plow excavated from Area 1 of the wooden-walled reservoir at Mongchontoseong. The plow, consisting of six fragmented pieces, was found in a decayed and cracked condition. Prior to conservation treatment, 3D scanning was performed to record baseline data, which was used throughout the subsequent process. Wood species identification revealed that the plow blade and body were Fraxinus (Oleaceae), whereas the remaining components belonged to Quercus spp., subgenus Lepidobalanus (Cerris group), Fagaceae. Examination of tool marks on the surface indicates that Plow No. 2 was manufactured using various implements, including axes, adzes, chisels, knives, and either a sickle or a plane. Conservation treatment followed the sequence of preliminary condition assessment, cleaning, consolidation, and vacuum freeze-drying. Consolidation employed PEG 4000 (aqueous solution), impregnated to a final concentration of 40%. Bonding simulations based on 3D data confirmed that the most stable configuration involved attaching the plow blade to Sul, and bonding and restoration were performed accordingly based on this configuration. The restored sections were subsequently color-matched to complete the treatment.
