Image: Solubility tests on painted bark cloth from Tonga
This image shows a conservator carrying out solubility spot testing on a painted bark cloth from Tonga. A cotton swab dampened with distilled water is rolled over a small section of paint under a microscope to see if water will solubilise the paint or dye. This is necessary to ensure treatments that use water, such as humidifcation treatments, will not cause bleeding or migration of the painted surface.
