Abstract
Wall paintings have been found in the façade of San Bartolome Church in Seville. The red colour was composed of calcite and iron oxides pigment. Another layer constituted by calcite was deposited over this red layer. Gypsum produced by environmental contamination or previous restoration was present in both layers. In other zones of the façade, the red layer was found without the presence of gypsum; however, cement was detected. In this last case, red colour was probably applied more recently. All studied colour layers were covered by an acrylic resin. The mortars were composed of calcite and quartz. © 2017, Ecozone, OAIMDD. All rights reserved.
