碩士 === 臺南藝術學院 === 古物維護研究所 === 92 === Developed with 5 chapters, this research aims at proper conservations of lead white darkening by exampling two problematic oriental paintings that has lead white darkening on it. This study contains recovery process, causal analysis and appropriate conservation. Besides theoretical discussion, the thesis presents an actual case as a technique exercise. Before we explore the issue, first of all we ought to establish a basic knowledge over lead white, in a word, the historical review, including: the history of lead white, lead white utilities in the East and West, lead white chemistry and causal analysis of lead white darkening made by modern conservationists. The recovery of lead white darkening is discussed by competitive studies of ancient / modern conservationists'''' handling and lessons from current major conservation institutes. As for the applied substances and recovery & cleansing, this research adopts viewpoints from Esthetics and Ethical Principles, along with scientific experiments and preservation procedures, in order to formulate the optimal material and treatment. In this study, traditional portraying is replaced by digital images modification, we see every possibility before and after varied recovering methods. Chemical reactions upon lead white darkening actually belong to preservation science. Limited within my field base, I collect literatures and outcomes from domestic and foreign scientific research as references. Finally the conservation project was achieved with minimized harm for the object. Hopefully this thesis would contribute to the lead white darkening management in the future.
