摘要

The structural analysis of multi-layered paint using embedded cross-sections has become standard practice for conservators and conservation scientists since the 1950s. Various methods and materials for the embedding of samples have been described since then, commonly using Polyester- or Acrylic resins. A rather new embedding-material is the light-curing single-component acrylic resin Technovit® 2000 LC. This article describes a suitable method for the correct sampling, embedding, processing and successful analysis of cross-sections using Technovit® 2000 LC and will show several examples of practical application of cross-section analysis on Taiwanese artifacts.

自從一九五零年代以來，使用鑲嵌式橫斷面分析來進行多層次塗料之結構分析已成為文物保存人員與保存科學家的標準作業。從那時起，種類繁多之樣本鑲嵌方法與材料陸續發表，而大部分皆使用聚酯或丙烯酸樹酯。一項嶄新之鑲嵌材料就是光固化之單組成之丙烯酸樹酯：Technovit® 2000 LC。本文將會以Technovit® 2000 LC來進行適當之作業，包括正確之取樣方式，鑲嵌，製程與橫斷面分析。並會展示在數件台灣藝術品上的實作橫斷面分析之成果。
