A study of conservation technology for the glass bowl unearthed from the underground palace of the Bao'en Temple in Nanjing

明代大报恩寺皇家建筑基址及北宋长干寺地宫的考古发掘是"2010年度十大考古新发现"之一,地宫出土的众多珍贵文物具有重大科学研究价值。本文以地宫内出土的一件编号为TN5的玻璃盏为保护研究对象,在前期分析研究的基础上,筛选了玻璃盏的黏接和灌注材料,并从表面清洗、碎片黏接以及裂缝灌注和修补三个方面,对玻璃盏实施了保护修复。修复后的玻璃盏基本保留了其原始形貌和负载的历史信息,取得了比较满意的效果。

Archaeological excavations of the Bao＇en Temple and the underground palace of the North Song Dynasty was one of the ten greatest archaeological discoveries in 2010. Many artefacts were unearthed from the underground palace, which have profound historical sig- nificance. This paper studies how one glass bowl （TN5） was ~paired based on the results of initial research and screening materials test. The bonding materials used for TN5 are Paraloid B72, and pouring material is a kind of epoxide resin （Araldite 2020#）. After the conservation and restoration, the glass bowl restores its original appearance and reserves its historical information to the great extent.
