In the recent past, the Stichting Restauratie Atelier Limburg (SRAL) developed a method for removing varnish from the surface of paintings by employing tissues saturated with simple solvent gels (comprising organic solvent and cellulose ether gelling agents only). Initially conceived for treating paintings in the Oranjezaal, Huis ten Bosch, the Netherlands, the use of solvents gelled and applied in this manner proved to have several advantages over their use as free solvents. The technique outlined here, with adaptations to the individual requirements of the painting, has since been employed in a variety of projects at SRAL. A fuller description of this technique can be found elsewhere.
