Abstract Mechanical properties—modulus of elasticity and strain at break, water vapour sorption, hygroscopic expansion selected egg tempera distemper paints were determined as a function relative humidity (RH) filling in this way critical gap the knowledge required for analysis fracturing processes paintings. The experimental work was made possible by preparation several paints, mimicking historical materials, form large specimens. Lead white, azurite, yellow ochre pigments, yolk rabbit skin...
Abstract Understanding canvas paintings as physical systems is fundamental to develop evidence-based environmental specifications for museums. A number of tests were carried out determine mechanical properties canvas, sized with animal glue and glue-based ground layer (gesso) a function relative humidity (RH). The the samples tested exhibited an anisotropy dependent on measurement direction, being stiffness corresponding weft direction greater than warp diagonal ones. Sizing significantly...
