Abstract

Albumen, silver gelatin and chromogenic prints are found abundantly among photographic collections in Egypt. Due to the uncontrolled environment in archives and libraries, this precious visual heritage with its high protein and cellulose content provides the right culture medium required for fungal growth. Many essential oils have been proven to have antibacterial and antifungal properties. Essential oils offer a safe alternative to other common disinfection methods; however, their effect on the properties of photographs have not received much study. This paper studies the effect of vapors of anise, cinnamon, clove, lavender and thyme oils on albumen, silver gelatin and chromogenic prints, to find a proper disinfection method that is user-friendly and environmentally safe and respects the nature of photographic materials. Essential oils were provided by the National Research Center (NRC) in Cairo, Egypt. Artificially aged albumen prints, and naturally aged silver gelatin and chromogenic prints were exposed in desiccators to the selected essential oils in the vapor phase for a period of 5 days. All samples were artificially aged at a temperature of 80°C and 65% RH for a period of 5 days to study the long-term effects of the tested treatments. Treatments were evaluated using several techniques including visual inspection, microscopic inspection, colorimetric measurements, and attenuated total reflectance Fourier transform infrared spectroscopy. Results showed that all tested essential oils had a very slight effect on the tested photographic samples; however lavender oil was found to be the best option, specifically in terms of preserving the chemical properties of the photographic surfaces.

五种精油作为绿色消毒剂对选定照片的消毒效果实验研究

在埃及的摄影收藏中发现了大量的白蛋白、银明胶和显色照片。由于档案和图书馆中不受控制的环境，这种珍贵的视觉遗产具有高蛋白和纤维素含量，为真菌生长提供了合适的培养基。许多精油已被证明具有抗菌和抗真菌的特性。精油是其他常见消毒方法的安全替代品;然而，它们对照片性质的影响还没有得到很多研究。本文研究了大茴香、肉桂、丁香、薰衣草和百里香油的蒸气对蛋白、银明胶和显色照片的影响，以寻找一种对用户友好、对环境安全且尊重摄影材料性质的适当消毒方法。精油由埃及开罗国家研究中心(NRC)提供。将人工陈化的蛋白照片、自然陈化的银明胶照片和显色照片在干燥器中暴露于所选精油的气相中5天。所有样品在80°C和65% RH的温度下人工老化5天，以研究所测试处理的长期效果。使用目视检查、显微检查、比色测量和衰减全反射傅立叶变换红外光谱等几种技术对治疗进行评估。结果表明，所有被测试的精油对被测试的照片样品有非常轻微的影响;然而，薰衣草油被发现是最好的选择，特别是在保护摄影表面的化学性质方面。

期刊介绍： Conservation Science in Cultural Heritage is an international peer reviewed journal which continues Quaderni di Scienza della Conservazione. Main topics of publication: • Study of the system: artifact-environment-biota • Historical-artistic knowledge of cultural heritage (i.e. author, art movement, period of realization, techniques, society and cultural characteristics, socio-economic context, commissioning, financing, interested public) • History, diagnosis, restoration, maintenance, conservation, valorization, prevention • Document research • Book, codex, and manuscript production in its historical context • Appropriate methodologies and analytical techniques used for the characterization of historical artifacts and evaluation of the conservation state • Environmental monitoring: assessment of atmospheric pollution and correlated degradation of monuments and historical-artistic sites • Micro and macroclimatic monitoring in confined areas (i.e. museums, libraries, archives, churches, galleries…) • Art diagnostics and evaluation of the authentication of art works • Art market and auction houses • Experiences in cultural heritage conservation • Evaluation of the suitability of products for restoration, conservation, and maintenance of works of art • Information science and cultural heritage: data processing and cataloguing methods • Virtual re-elaboration and use of historical artifacts and environments • Study, valorization and digitalization of archive and library heritage • Environmental context and technical-conservative issues related to historic architecture • Virtual or traditional conservation, cataloguing and processing of photographs • Various other topics including education, safeguard, education, legislation, economics, social aspects, management, marketing, interdisciplinarity, internationalization, etc.
