Fig. 8From: The use of ground glass in red glazes: structural 3D imaging and mechanical behaviour using optical coherence tomography and nanoindentationStorage and loss moduli of the sample B1 (with no glass particles) at an indentation depth of 2 µm measured for a frequency sweep of 5 measurements from 1 to 10 Hz at an amplitude of A = 0.05 μm; the increase of the moduli with the frequency indicates the viscoelastic behaviourBack to article page
