Modern Wedding Invitations and Invites | Love vs Design. Doggelganger. Closer to Van Eyck. The panels of the Ghent Altarpiece are coated with layers of varnish. Varnish serves as a protective coating for paint layers and has important optical functions, since it saturates a painting's colors and creates a more even surface. However, most varnishes gradually degrade over time, getting brittle and opaque, and becoming a darkened and yellowed layer that can dramatically impact the perception of a painting's colors and tonal values.
Since a degraded varnish will make the dark areas appear lighter, it will also affect our perception of the rendering of volume and space. Applying a new layer of varnish over a degraded one can sometimes improve the situation for a time, but restorers routinely remove and replace old varnish layers. During the 2010 urgent conservation treatment of the Ghent Altarpiece, cleaning tests were performed to establish the condition, compounds used, and solubility of the varnish layers.
