|Abstract:||The consolidation treatment of azulejos is indispensable when there is a debilitated or disaggregated ceramic biscuit and/or one wishes to reestablish a weakened glaze-ceramic adherence. In this communication the impregnation profiles obtained via mass consolidation on ceramics conservation are presented. An acrylic resin, an ethyl silicate and a nanolime were used to determine the micro-drilling relevance for the evaluation of consolidation treatments applied on ceramics. This technique allowed to observe the impregnation patterns which cannot be determined by the mechanical strength tests (flexural and compression) commonly used to evaluate the consolidation effect.|
