Abstract

The aim of this study is to highlight the appearance of deterioration resulting from weathering effects on the beech wood used in the ornamentation of wooden window grilles (Mashrabiya) in the Mosque of Prince Hassan, in Akhmim-Sohag and in the Mosque of Khawand Asalbay, in Fayoum, Egypt. This wood was accurately examined with a Digital microscope and Scanning Electron Microscope (SEM) to diagnose the deterioration processes on the surface of the wood. Fourier transform infrared (FTIR) was used to identify the changes in the main components of the beech wood resulting from weathering factors. The chromatic change of the beech wood surface was measured by spectrophotometer and the results were calculated by using the CIE-L*a*b* system. Results showed the physical and chemical changes that had occurred in the degraded beech wood. The results helped to develop a treatment plan using already experimented materials that do not harm the wooden artifacts.

户外山毛榉木材的风化及保护方法

这项研究的目的是强调在Akhmim-Sohag的哈桑王子清真寺和在法尤姆的Khawand Asalbay清真寺的木窗格栅(Mashrabiya)装饰中使用的山毛榉木材的风化作用所造成的劣化现象。用数码显微镜和扫描电子显微镜(SEM)对木材进行了精确的检查，以诊断木材表面的劣化过程。利用傅里叶变换红外(FTIR)技术对山毛榉木材主要成分在风化作用下的变化进行了分析。用分光光度计测定了山毛榉木材表面的色度变化，并用CIE-L*a*b*体系计算了结果。结果表明，退化后的山毛榉木材发生了理化变化。研究结果有助于制定一项治疗计划，使用已经试验过的材料，不会伤害木制文物。
