| Abstract | 本研究以魯土司衙門晚期建築塔爾殿和早期建築萬歲殿壁畫為例,採用多光譜成像、便攜式X-熒光儀(XRF)、便攜式近紅外光譜儀(NIR)、便攜式數碼顯微鏡等無損分析技術,在遺址現場對壁畫的製作材料、工藝、歷史幹預等進行調查研究。多光譜攝影調查發現塔爾殿壁畫所用顏料成份復雜。萬歲殿主殿壁畫局部有重繪現象,迴廊壁畫沒有發現重繪和修改的現象,屬明代早期原繪壁畫。採用XRF結合NIR原位-無損分析相互提供佐證信息,可以確定絕大部分顏料,並經室內XRD分析驗證。壁畫的主要顏料紅色為鉛丹、硃砂,綠色為巴黎綠、氯銅礦、石綠,藍色為人造群青、石青,黃色為雌黃、金,白色以鉛白、石灰為主。部分顏料如黃色、藍色,使用有機顏料可能性極大。氯銅礦和石青只發現於萬歲殿迴廊。壁畫顏料使用時代特徵明顯。四種原位-無損分析方法結合,可以應用於壁畫類不可移動文物製作材料分析、價值認知、幹預歷史調查等方面並取得良好的效果。
This study has chosen imperial offices as case studies, namely the Wansui Palace built in the early period of Chieftain Lu and the Taer Palace from a later period. The nondestructive analysis techniques of multispectral imaging, portable X-ray fluorescence spectrometer( XRF), portable near infrared spectrometer(NIR), and portable digital microscopes were used for the in-situ investigation of the production materials and technologies and the historical alteration of the wall paintings. A result of particular note is that the multi-spectral imaging suggests that the pigments used in the Taer Temple are of a highly complicated chemical nature that will require further analysis. The wall paintings in the main hall of the Wansui Temple have been partly repainted but those in the cloister remain untouched, showing that the paintings in the latter are original artworks dating from the early Ming dynasty. The vast majority of pigments have been identified by using XRF together with NIR and verified by laboratory XRD analysis. The results show that the main pigments of the wall paintings, which exhibit obvious temporal characteristics requiring further understanding, contain lead tetraoxide,cinnabar, emerald green, atacamite, malachite, artificial ultramarine, azurite, gold, orpiment, white lead, and calcite. It should be noted that some pigments, those used for yellow and blue coloring for example, are very likely to be organic pigments; also, atacamite and azurite were only found in the corridor of the Wansui Temple. The combined use of these four in-situ nondestructive research methods is very promising for application to the analysis of immovable relics and it is hoped that this approach can be applied to other delicate cultural objects with similar success. |
