Abstract

An extraction of soluble salts from frescos was performed using sheets of Japanise paper embebbed of ultrapure water. A mixed sampling method, random sampling and purpositive sample design, was adopted in order to obtain significant information about the role of soluble salts in the degradation of a frescoed chapel located in a roman church. Salts were then recovered by the sheets using ultrapure water and the obtained solutions analysed by Ionic Chromatography (IC). Temperature, humidity and drying time were also measured on each sampled zone and all the obtained data were treated by Principal Component Analysis (PCA)
