ABSTRACT
The purpose of this work was to carry out the diagnosis and vulnerability analysis of the ceramic and glazed terracotta tombs of Omnium Sanctorum church (Seville, Spain) by non-destructive techniques such as X-Ray fluorescence (XRF) for chemical analyses of tiles, and 3D digitization to identify the main weathering forms. Efflorescence, detachment, cracks and loss of glazed materials were detected by 3D digitization and compared with the results obtained by in situ inspection, while XRF analysis discovered the composition of tiles without sampling. The combination of these non-destructive techniques allowed to know the composition of the materials and to establish that dampness by capillarity may be the main cause of weathering.
