Abstract
As part of the first work stage that considered the evaluation of the feasibility to restore the sculpture of the Virgen del Carmen, the Cncr Analysis and Monuments laboratories carried out studies on the materials, which served to orient in the intervention of the image. These studies focused on two main areas: the analysis of the image, which led to the characterization of the damages, and the study of possible materials and intervention techniques that could be used. The damage characterization considered evaluating the depth of the burns by collecting micro-samples of carbonized areas up to the wood, determining its state through optical microscopic analysis. Results indicated that the carbonized layer of the image of the Virgin reached a thickness of 7 mm while for the image of the Child, reached levels of 12 mm. Meanwhile, the studies conducted to determine the most appropriate materials and intervention techniques, consisted on preparing models of burnt wood and consolidating the carbonized areas with solutions of PVA-AYAF and Paraloid B72 in ethyl acetate at different concentrations. Then layers of calcium carbonate and sulphate preparations were applied. The models were subjected to successive stages of controlled changes in temperature, humidity and sun-equivalent radiation, in addition to mechanical resistance testing. Throughout the entire process, the models were systematically followed up to evaluate any macroscopic and microscopic observable change of the surface. The best results were obtained with a 5% and 10% concentrate of Paraloid B72 solution.;(A.A.)
