The present research concerns the Roman wall paintings preserved at Insula del Centenario (IX, 8), the important Pompeian block situated in the Regio IX, along Via di Nola.
The aims of this research are two: to verify the presence of lipidic and proteinaceous material to spread the pigments, and to identify organic matter in painting materials owing to previous restoration works. The samples collected from the wall paintings of different rooms have been investigated by Fourier Transform Infrared Spectroscopy (FT-IR), and Gas Chromatography/ Mass Spectrometry (GC/MS).
The analytical results show that these Roman wall paintings were realized without the use of lipidic and proteinaceous materials, supposedly in fresco technique. Moreover, it was detected that wax, egg, and animal glue were used in previous restoration works for protective purpose and to restore the wall paintings to their original brilliant colours.
本研究关注保存在百年纪念街区(IX,8)的罗马壁画,该重要的庞贝街区位于第九区,沿着诺拉大道。
本研究有两个目的:验证用于传播颜料的脂质和蛋白质材料的存在,以及由于先前的修复工作确定绘画材料中的有机物。从不同房间的壁画中采集的样本已通过傅里叶变换红外光谱(FT-IR)和气相色谱/质谱(GC/MS)进行了研究。
分析结果表明,这些罗马壁画的绘制未使用脂质和蛋白质材料,推测采用的是湿壁画技法。此外,检测到在先前的修复工作中使用了蜡、鸡蛋和动物胶,用于保护目的并使壁画恢复其原来的鲜艳色彩。
