Fig. 7From: Understanding and optimizing Evolon® CR for varnish removal from oil paintingsA selection of ATR-FTIR spectra recorded on a zinc-containing oil paint binding medium model system exposed to unwashed Evolon\(^\circledR\) CR loaded with ethanol (no controlled loading) for over 3 h. After about 50 min, a small peak assigned to crystalline zinc soaps (1540 cm\(^{-1}\)) is visible, which continues to increase before stabilising after about 100 minBack to article page
