Resumen

Las diferentes técnicas de pintura, materiales y métodos de aplicación que caracterizan las obras de arte contemporáneas, con predominio de superficies mate y tonos uniformes, hacen de la reintegración cromática uno de los tratamientos de conservación más complicados, ya que la similitud es el objetivo principal. La intervención de reintegración realizada en Galleria Nazionale d’Arte Moderna e Contemporanea en Roma, en Tempi prospettici (1969), una instalación del artista italiano Carlo Alfano, dio la oportunidad de investigar un método para obtener diferentes valores mate / brillante a través de uso de polímeros naturales como aglutinantes. Los aglutinantes elegidos (diferentes polisacáridos, derivados de celulosa y pegamento de esturión) se analizaron, individualmente y mezclados, utilizando medidas colorimétricas y glosimétricas. La relación pigmento-aglutinante y la adición de sílice también se evaluaron para obtener la modulación de la apariencia mate de las formulaciones de pintura. La comparación de los valores colorimétricos de las muestras de pintura y los de la pintura original condujo a la identificación de la mejor solución para la reintegración de la obra de arte.

Since September 2018, she is coordinator of CoCARe Network with Federica Bressan.

Philip Morelli, Professional for conservation

After a BA in conservation of wall paintings he continued his studies with a five-year course at the School of Higher Education of the Opificio delle Pietre Dure in Florence in the fields of wall painting, stone sculpture and mosaic conservation. He is actively involved in international research projects with public institutions (such as the Galleria Nazionale d’Arte Moderna in Rome) and private firms. Most recently he has worked on the conservation treatment of the Sepulchre of Ramon Llull in Palma de Mallorca (Spain). Philip Kron Morelli’s main research interest is to deepen the knowledge of traditional materials such as adhesive and consolidants for cultural heritage which he presented in several publications and conference papers and to develop new supports for detached wall paintings. Since 2012 he has worked as a professional for conservation projects on several Florentine masterworks by MarioUo di Nardo, Bernardino PocceV, Antonio Rossellino, BenedeUo da Maiano, Alessio BaldovineV and Antonio del Pollaiolo.
