Hi list, I would think the best way to uncurl old photo's would be to soak them in clean water until they go limp and then dry them again with care between acid free blotters. I think you may find if you try to uncurl them while dry the emulsion may well crack but a water bath shouldn't do them any harm as long as the water is clean and pH neutral ( this would have been their last chemical bath anyway when they were printed). I would however caution that you try one or two of the less important or damaged ones first and as has already been said don't rush it and let them dry slowly. A quick look in my "Life library of photography", "Caring for Photographs" book they say that uncurling an old a brittle print may be beyond the amateur and that an expert should be sort. However it does give a method that may be used and should be safe as long as the materials used are all acid and chemical free. 1. Place print face down on to a clean surface 2. Gradually flatten the print out, on the back, with a damp sponge. 3. Place the flattened print between clean blotters and press it with a heavy object larger than the print and allow to dry. 4. When dry inspect the print and if required repeat the process. Please note the sponge as well as any blotters will need to be chemical free and pH neutral so you may need to get them from a good photographic store. Good luck and if you have a go please get back to the list and let us know how you went. TTFN Colin ;o)
