By examining the mechanical and dimensional behavior of artists’ materials with respect to changes in ambient relative humidity it is possible to identify those materials that are at risk. This workshop will show the results of tensile tests, swelling isotherms, and restrained testing of artists’ linen canvases, hide glues, gessoes, and oil paints. While many of these materials together can act as a composite painting structure, it is possible to show which individual layer is developing either high or low stresses with changes in humidity. It is also possible to show illustrations of actual damaged paintings and relate their damage to specific properties of individual artists’ materials and the environments inducing the damage.
Additionally, from examining the properties and performance of the individual artists’ materials, one can determine the properties required for possible consolidating adhesives in order to properly restructure a damaged painting.
