Artificial aging and deterioration of oil‐painted Fabriano paper and cardboard paper supports

Fabriano paper and cardboard are commonly used for oil paintings as paper supports. There are different practices for oil painting. Sometimes, painters paint directly on paper supports. They may also impregnate paper supports with linseed oil before painting to prevent the absorption of the binder from the oil‐based paint by the paper, or they may apply a background (e.g., animal glue and calcium carbonate) on the paper supports and then paint their drawings. The effects of aging by heat or ultraviolet light on the mechanical properties (tensile strength, tensile elongation, and tearing resistance), optical properties (changes in color indices), and pH of Fabriano paper and cardboard painted with the aforementioned practices were studied. In addition, the thermal stability of paper painted with these practices was studied with thermogravimetric analysis.
