Paper Abstract

Varnishes used for the protection of paintings are also key factors influencing the appearance of paintings, since they are able to provide more gloss and saturated colors. In order to give a stable appearance to a painting, varnishes must have stable or reversible optical characteristics (color, refractive index) even in the presence of different environmental conditions. This work describes how optical fibers can be used to monitor temperature effects on the varnish refractive index.
