RT Journal Article T1 Effect of conservation treatments on heritage stone. Characterisation of decay processes in a case study A1 Varas Muriel, María José A1 Pérez-Monserrat, Elena Mercedes A1 Vázquez Calvo, María del Carmen A1 Fort González, Rafael AB Preliminary studies are an imperative when determining the impact of conservation treatments on historical materials. The Romanesque apse on a church at Talamanca de Jarama, Madrid, Spain, whose dolostone was severely decayed by rainwater and salts, was treated in the past with substances that ravaged the restored area. Petrological techniques showed that salts leached out of the cement under the roof onto the stone cornice whose surface had been coated with synthetic resins. During evaporation, the salts precipitated in the stone and underneath the resin, inducing blistering, fissuring, flaking, scaling and detachment of part of the restored decorative elements.
