Abstract Green pigments in micro-samples taken from three late-medieval painted objects from Norwegian churches have been investigated with the aim to characterize their constituents and understand how they relate to damages observed in passages containing green paints. The cross-sections were analyzed by optical microscopy under visible and UV light, Scanning Electron Microscopy coupled with Energy Dispersive X-Ray Spectrometry and vibrational spectroscopies (Raman, ATR-FTIR). In addition, Gas Chromatography coupled with Mass Spectrometry was employed for the characterization of binding media, using a derivatization methodology recently developed for the detection of metal soaps in paint samples. This extensive characterization aided the identification of the individual constituents and the stratigraphy of green paints. It also builds the foundation for future ageing studies that can provide better insights into the mechanisms of the processes at stake in selective delamination of paints containing copper complexes.

中世纪晚期挪威教堂彩绘翅膀中绿色颜料和粘合剂的鉴定

摘要 对取自挪威教堂的三个中世纪晚期彩绘物体的微型样品中的绿色颜料进行了研究，目的是表征它们的成分并了解它们与在包含绿色颜料的段落中观察到的损坏之间的关系。在可见光和紫外光下通过光学显微镜、扫描电子显微镜与能量色散 X 射线光谱法和振动光谱法（拉曼，ATR-FTIR）分析横截面。此外，气相色谱与质谱联用被用于表征结合介质，使用最近开发的衍生化方法来检测油漆样品中的金属皂。这种广泛的表征有助于识别绿色涂料的各个成分和地层。
