| Sumario: | [EN] One of the most aggressive agents of deterioration that can affect the colors of a painting easel, is the damage caused by extreme heat. This type of alteration is manifested as blisters, extreme stiffness and loss of elasticity of pictorial materials, is extremely complicate the processing of color fixation. In this paper, the fundamental elements that come into play in these exothermic reactions are analyzed. The original paint layers performance and the consolidating materials suitability was considered too. The study methodology was divided into three main stages. First, a study of the physical - mechanical behavior of oil paintings on canvas commercial primer (used routinely by the artists) when they are subjected to extreme temperatures was performed. Later, we analyzed the types and degrees of alteration proceeded to the experimental laboratory, by comparative of different materials consolidating. Finally we proceeded to the elaboration of a specific methodological guideline, to facilitate this complex treatment. |
