Egg tempera is a painting technique that was used by great artists through the centuries as it gives great plasticity and color brilliance to whichever artwork is used. Pigments can be natural or synthetic, inorganic and organic, grounded into fine powders. The green pigments, to which this study is focused, such as malachite or verdigris, are used since ancient times but are very problematic and unstable colors [1]. Determining the degradation mechanisms of these materials helps a conservator to plan the methods of preventive and interventive conservation of works of art, which has aesthetic aims and also leads to prolonging life expectancy as well as better exhibition and storage conditions in the future [2]. The present analysis is part of a comprehensive study of the artificial aging of pigments in different painting techniques and focuses on different green pigments (malachite, verdigris, viridian, green earths etc) mixed with egg yolk as a medium. The samples were aged artific...
