Mode of swelling in binary solvent mixtures of benzene–n-hexane and acetone–isooctane, reproduced from Stolow [87]. Film (i): vacuum stand oil and 0.5% lead naphthenate, 7 weeks at 32 \(^\circ \text {C}\); film (ii): vacuum stand oil and 0.5% lead naphthenate, 72 h at 80 \(^\circ \text {C}\); film (iii): alkali refined linseed oil and 0.5% lead naphthenate, 72 h at 80 \(^\circ \text {C}\); film (iv): open pot stand oil and white lead pigment, 18 weeks at 32 \(^\circ \text {C}\). All films were pre-leached in acetone (film i–iii) or methanol (film iv). Swelling capacity expressed as volume change (\(\Delta V/V_{0}\)) corrected for initial film density \(\rho\) (density before the experiment)
