Summary

MARTINOVIC MEDJERAL PAVLEKAThe main focus of this presentation is on materials used in conservation of wall paintings, which were presented on various conservation workshops held during 2013.
The presentation summarizes workshop experiences and highlights the importance of utilization of thus gained knowledge. It is divided into three basic chapters. The first part provides basic information on wall painting conservation materials and their characteristics, used for pre/consolidation, cleaning and desalination of wall paintings. The second part gives a concise overview of materials' presentation on various workshops. The last part of the presentation describes the subsequent application of the discussed conservation materials in the OKIRU wall painting studio. The characteristics of inogranic materials for wall painting conservation were ascertained through practical work and execution of empirical probes.
The assessed inorganic materials were the following: ammonium carbonate, barium hydroxide, EDTA tetrasodic, AB 57, various nanolimes, Nanoestel 2000 and cation exchange resin. The results have been critically evaluated and compared with expected outcomes.
