中文摘要 | 本試驗主要以糖醇法、聚乙二醇法、溶劑-單體浸漬法,依據實際操作之過程及加固後之尺寸變化情形和處理結果進行探討,提供文化資產保存修復人員參考。本試驗試材為考古遺址周邊發掘出土之木材,以探針測試表面鬆軟而中心部分尚留有強度,平均含水率500%以上,屬嚴重劣損程度。(1)本試驗結果在尺寸安定性方面,飽水木質遺物經PEG400+4000、PEG4000處理後尺寸安定性較佳,而糖醇法在不同試材和處理程序上結果差異大,而溶劑—單體浸漬法尺寸安定性較差,可能為試驗設備侷限所造成。各種保存處理方法於處理過程及處理後之乾燥過程均頇密切監控及進行調整措施,方可取得最佳之加固效果及外觀。保存處理後亦頇進行必要之清潔處理,方能有可接受之外觀形態、色澤和質感,但加固材料造成之質感變異則無法由清潔工作改善。(2)本試驗採用之試驗操作以依試驗條件完成加固程序為主,取得試材之尺寸變化情形,但就教育推廣而言,處理後之外觀等,難以呈現乾燥木材之質感、色澤。如本試驗使用聚乙二醇和溶劑—單體浸漬法處理後呈現半透明之蠟質感,視覺上已脫離民眾對木材外觀之認知,在日後展示處理時恐無法讓民眾對該物件與木材有共同的意象,而出現感官的落差。 |
英文摘要 | This study focuses on the assessment of the consolidations of waterlogged archaeological wood with different impregnation treatment methods, including lactitol method, polyethylene glycol (PEG) method, and solvent-monomer soaking method. A series experiments were conducted to assess the stability of the preservation methods with different solutions and different operating procedures. The specimens, waterlogged archaeological woods, were excavated from the archaeological site, have a soft and spongy exterior change surface layer and a relatively hard core according to the pin test. The average moisture content of the specimens is above 500%, therefore the specimens are considered as being in a serious state of decay. (1) The dimensions of specimens prior to and after treated with solutions were measured. The results show that the shrinkage of specimens treated with PEG 400 + 4000 and PEG 4000 are very small; meanwhile, the shrinkage of specimens treated with lactitol is quite different from those treated with solvent-monomer soaking method due to the substances and operating procedures. In addition, the specimens treated with solvent-monomer soaking method are seen as more instable than those treated with other solutions as discussed in this study, due to the limitation of experimental equipments. No matter using what preservation methods to preserve the waterlogged wood, the drying process should be continuously monitored and adjusted carefully during and after the preservation process if the conservators want to obtain the best consolidation and proper exterior change of the specimens. In addition, after the consolidation, the surface cleaning of the specimens is necessary for acquiring the proper and acceptable exterior change, color tones and texture. However the texture variation associated with the consolidating solution cannot be totally modified by the surface cleaning. (2) The main objective of this study is to evaluate and discuss the stability of specimens treated with different solutions. However, after the treatment, no matter what solution or operating procedures we used, the textures of the preserved waterlogged archaeological woods were different from the ordinary dry woods. For example, the specimens treated with PEG and solvent-monomer soaking method would have translucent wax texture. Thus, it should be noted that the preserved woods may not be suitable for the purpose of exhibition and promotion. |
