Hello, I am working on a Roman glass vessel suffering from delamination of the iridescent patina. The patina is limited to one side of the object and it is quite fragile. It has flaked off easily. I attempted consolidation with 10% Paraloid B72 w/v in 50:50 ims:acetone as well as 12% Paraloid B72 w/v in acetone. For some reason the areas where the consolidant was applied became white. I think this is due to the space between the delaminating layer and the substrate. When I applied acetone to remove these white spots the area went white before the solvent evaporated. I am wondering whether anyone has experienced a situation like this and if there are any recommendations for consolidating such an object in light of the difficulty I mentioned above.
