description
Sterzing marble, a crystalline white marble used in the late-Baroque garden sculptures of Schoenbrunn Palace in Vienna, was studied by means of thin-section and scanning electron microscopy in order to obtain a better understanding of its surface decay caused by atmospheric weathering. Following the classification of distinct phenomena of deterioration by visual on-site inspection, the micro-structural features including surface erosion, micro-cracking, soiling, black crust formation, and microbiological infestation are exemplified by microscopical images and briefly discussed. The results proved useful for evaluating and understanding the various types of marble decay for creating a safer basis for establishing the procedural principles aimed at conservation and maintenance of the sculptures.
