Abstract
The mineral composition of pigments from mural paintings of the 12th and 13th centuries in the grotto monasteries of Bertubani and Udabno (David-Caredga) were investigated. Apart from traditional pigments, many examples of brown-black plattnerite (PbO2) were found. They were generated by bacteriological oxidation of white lead. This oxidation process has caused great damage to the original painting color. It is necessary to investigate and to remember the potential influence of bacteria on painting pigments while conducting conservation and restoration as well as art historical analysis. -- CAL -- CAL
