本項計畫針對國立台灣歷史博物館籌備處(以下簡稱台史博)所提供的五十一件文物進行調查研究。有關繪畫技法、基底材與顏料運用、形式分析及保存建議,可提供未來此類文物的保存修護基礎,輔以科學設備儀器分析顏料,了解設色技法及繪製過程,例如大部分祖宗畫像其紅色顏料為使用朱砂或辰砂(HgS),經由X射線螢光元素分析(XRF)結果,除其含有汞(Hg)元素之外,另有鉛(Pb)元素的發現,其於底部都有以鉛丹(Pb3O4)打底,此發現將古典或已失傳的技藝記載下來,對於未來相關保存研究工作有其重要性。有關普魯士藍的發現是本研究計畫的另一項收穫,並經檢測分析結果,最少可認定台灣在九十年(1914)前即已有使用普魯士藍的記錄,而此一記錄對文物年代的鑑定有其參考性,因此未來是否能經由其他類似研究將台灣普魯士藍的使用歷史再往前推進是值得期待。運用文資中心的科學設備儀器、專業修護空間及人力對祖先畫像所作之顏料層檢測分析雖有一些成果,但由於每一畫像的相關歷史大都不可考,且又考證困難,因此較無法結合歷史研究與科學分析之利,進而降低了此一檢測分析的價值性,以及資料庫建立之困難度。 This project will conduct survey and research of fifty glue-color artifacts from the National Museum of Taiwan History. The survey includes analyzing the techniques of painting, their soporte and the usage as well as the form of pigments, which can offer basis for future conservation of glue-color artifact. By the assistance of scientific equipments, we can analysis the condition of the artworks and the reason of damage and deterioration, or bequeath as well as document ancient or lost skills. For instance, we found that most red pigments used on the paintings are HgS after XRF analysis. This study can also benefit to represent traditional skills and related preservation research in the future. By the assistance of scientific equipments, professional facilities and specialties of the NCRPCP, we conducted analysis of pigments used on the glue-color ancestor portrait paintings. However, because it is very difficult to research the history of each portrait, the value of this analysis is reduced. Moreover, it raises the difficulty when building the database.
