CONSERVATION AND ENVIRONMENTAL CONDITIONS IN A TEMPORARY STORAGE AREA OF PALAZZO SOLIANO IN ORVIETO

This work concerns a conservative and environmental study of the first floor of Palazzo Soliano, an historical building located next to the Orvieto’s cathedral which is temporarily used as a storage area by the M.O.D.O. (Museo dell’Opera del Duomo di Orvieto). The cultural properties housed in building consist of heterogeneous materials (textile, ceramics, glasses, stone materials, canvas, metals, paper). These objects are preserved in different storage units (racks, shelves and cases). The study of the storage area and of objects conservation conditions was realized by using the Environmental Data Sheet (EDS) and the Collection Data Sheet (CDS), a methodology developed by Istituto Superiore per la Conservazione ed il Restauro. The EDS is a tool that helps to highlight the features of the storage environment, by carrying out seasonal microclimate monitoring, as well as chemical air quality and entomological monitoring campaigns. Through the correlation of all these data with the information collected with the EDS and the CDS, it was possible to evaluate the conditions of the objects in relation with the environmental, structural and architectonic characteristics of the storage area. This study allowed to detect some causes, linked to the main typologies of objects decay.
