From: A holistic view on the role of egg yolk in Old Masters’ oil paints
DSC curves (a) and relative amount Py/GC/MS extracted ion pyrograms (b) of ultramarine blue (UB) and lead white (LW) model paints up to 180 days of natural ageing. Solids content of UB LO, UB PCP, LW LO, and LW PCP are φ = 6, 33, 31, and 29 vol%, respectively, including 12 vol% (UB PCP) and 15 vol% (LW PCP) of EY. b The evolution of the oil polymeric network (m/z 129), the azelaic acid (m/z 317), and the oleic acid (m/z 339) of the different formulations at the same curing time. All DSC curves are normalized to the oil content and all the relative amount of the pyrolysis products to the palmitic acid peak m/z 313. PCP stands for protein-coated pigment paint and LO for oil paint.
