I tried 1/5 teaspoon of Kosher salt (no anti-caking additive) into 1/3 cup filter water (~ 3% saline), and one capsule of Pacreatin. It helped a bit, though it could also be that these stamps have seen quite a bit of soak time. Still acouple of stamps scrolled up, but they weren't as difficult to flatten and get = from blotter to drying book, I am out of 'problem' stamps so whether a higher saline concentration helps (or maybe it makes little difference at all)... will have to wait a while. Fortunately I don't see this issue with all early Austrian stamps. Stan, our FORUM chemist  |

Batch of 30-40 nice 1980s Brunei soaking this am. Clipped from FDC unsold on eBay after 4 months. Going to try club circuit packet.
20 mins in tepid water in a Pyrex glass bowl . Dry face down on kitchen towel .
Amazed how cloudy milky the water has turned presumably some starchy constituent of the paper or the gum.
