- Résumé
- Zinc oxide has been incorporated into oil paints since the 19th century, initially used in commercial applications followed by the adoption of zinc white into artist’s materials in the 1900s. The zinc oxide content in oil paint has been associated with the deterioration of paintings, with in-depth research into the chemical and physical aging processes examining the pathways of damage. Conservation issues include the formation and effects of zinc soaps and the physical drying processes of zinc oxide in oil paint resulting in brittle paint films. These have led to questions surrounding the long-term effects of even the most basic conservation treatments. The 1967 oil painting Nu Féminin, by Canadian artist Jori Smith, is an example of a mid-century painting exhibiting severe deterioration. Showing overall delamination of the paint layers from the ground and support structure, Nu Féminin has undergone extensive analysis to investigate the cause of the damage. High levels of zinc found at the delamination interface as well as within the paint layers has been hypothesized as the leading cause of the deterioration. This research examines the practical aspects of treating a fragile and delaminating paint film, such as deciding upon appropriate adhesives and application methods, while also probing the ethical considerations a conservator must balance regarding intervention. In addition, the documented treatment of a work of art with known zinc oil paint content will add to the greater body of research on the long and short-term effects of materials and methods relating to similar paint structures. Cracking and delamination of the paint layer similar to others with high concentrations of zinc within the paint layer, as well as continued analysis of the paint film and delamination interface confirmed that zinc within the oil paint was the major cause of the paint cleavage and delamination. The final procedure for flattening and consolidating the paint layer eschewed the use of water, relying on heat alone to soften the paint film, gentle heated pressure to press the cupping paint flat, and to reactivate previously applied BEVA 371, resulting in a passable final consolidation outcome.
