By the hand of Teresa Cortez we are escorted to a motif which we deem very special, a subject we address with great delight – the tile mural. This is undoubtedly a peculiar form of expression, a form that differentiates itself even in its production process, which we consider as endlessly creative: piece by piece, tile by tile, the creation is invariably marked by difference, in a process genuinely averse to any attempt at normalisation or mere reproduction; in short, no two pieces are exactly identical. The tile is subject to a whole process of artistic production which is inevitably linked to the multiplicity of its variables: some of them more contingent on the author (her style, the modelling, the painted chromatic values and the firing times), others, more difficult to control (reaction of materials to different temperatures and among themselves – some blend together, others overlap one another; some become more glazed; others more or less dull). This is an extensive and very significant work in the context of ceramics and national public art.
