    Abstract
    Glazed porous ceramic tiles are used for wall tiling due to their high humidity absorption, which produces deformations in them. These tiles have a good surface appearance due to its glazed layer, and polishing is not required. However, some manufacturers proceed to its subsequent polishing, obtaining high-gloss tiles. Nevertheless, the polishing process of these parts is complex because it is very difficult to obtain pieces with the flatness required for polishing, due to different contraction coefficients between the ceramic base and the glazed surface layer. In addition, during the polishing process the parts absorb water used in the process, which produces a change in its geometry, causing a decrease in productivity and a high number of defective parts. In this work a study of the geometry evolution of these pieces according to humidity content and elapsed time is carried out, and a strategy of parts pretreatment prior to polishing is proposed, which allows increasing the productivity by improving the flatness.
