文物詮釋下的修護評估──奇美博物館典藏西方十九世紀銀質紀念杯的清潔試驗

Cleaning Test of 19th Century Silver Trophies at Chi Mei Museum, the Consideration from Exhibition Point of View

執行修護前應考量文物的材質天性與劣化機制，除了安全穩定，達到視覺美感上的完整往往是主要訴求。奇美博物館籌備期間，修護人員檢視一批館藏西方十九世紀瑞士地區射擊節的紀念杯。故而本文整理西方十九世紀銀器製作的材質與技藝，分析展示需求如何影響修護處理前的評估。並藉由清潔方式與清潔材料對銀試片的表面影響試驗，建立奇美博物館典藏銀杯修護的參考依據。試驗記錄整理機械式、化學式與電化學式三種清潔方法，達到清潔效果的時間與使用經驗。結果顯示機械式的清潔效果最佳。

It is conservator’s obligation to understand the material nature and the deterioration mechanisms of an object before treatment. Aesthetic issues can be a major factor that influences the conservation assessment, in addition to safety considerations. The techniques and the materials used to produce silverware in the 19th century in western culture are here introduced. The point of view with regards exhibition needs is also discussed in this article. A comparison test of cleaning methods and materials was conduct as a reference before the conservation treatment of Chi Mei Museum’s silver collection. The test results suggest that of three different kinds of cleaning method, mechanical cleaning achieved the better result.
