Fig. 1From: Evolution of the viscoelastic properties of painting stratigraphies: a moisture weathering and nanoindentation approachRepresentation of the mock-ups prepared for the indentation tests. The behaviours of the three outmost layers were evaluated: the grey ground in Canvas 1, the madder in Canvas 2 and the ultramarine in Canvas 3. The intermediate madder layer in Canvas 3 is also studied by indenting the side of the sample (the studied layers are indicated)Back to article page
