Abstract

The initial results of a research project on the investigation of problems presented by a collection of oil paintings on paper supports are presented. The project focuses on the effect of the oil medium on the deterioration of cellulose, on the materials and techniques used by the artists and on comprehension of the resulting problems.

Non destructive methodology was used to record the behaviour of the materials when examined in several regions of the electromagnetic spectrum which gives an indication of areas of damage. . Various analytical techniques were applied to investigate the painting materials and supports in original works of art. The increase in rate of the oxidation of cellulose in paper, when the paper is coated in oil, is investigated by analyzing volatile organic compounds emitted during ageing tests.

The assessment of the results obtained will act as a pilot for a more extensive program of research, the ultimate aim of which is the formulation of a recommended methodology as a tool for the evaluation of the condition of these types of works, as well as the determination of conservation and care parameters.
