A painting on canvas can be treated as a composite of inhomogeneous polymer layers. The key to understanding the deterioration processes is understanding how these layers interact. The first step is a knowledge of the fundamental mechanical properties and a working theoretical framework, verifiable by experiment, which can predict easel painting behaviour. A biaxial tensile tester has been built to investigate easel painting mechanics. A series of experiments have been conducted which demonstrate how each process, in constructing an easel painting, modifies its uniaxial and biaxial mechanical properties. Initial results reported here, concentrate on plain weave cotton-duck as the support, and the application and effect of the size layers. These results are used to test the conventional description of an easel painting as a deformable solid. It is suggested that alternative mechanical models might be more suitable when considering the painting as a whole.
