Trying to find out what type of horse / animal / junk glue Austria used on the Franz Josef "head" issues, among others. This gum (if you want to call it that) is so nasty, you can clean it, clean it and still clean it some more.
They had different perfs by the score, different paper types, and plenty of different gums (urrrggghhh) that one could take a lifetime to sort them all out. Michel and Netto do a pretty good job at distinguishing between them in their catalogs.
What did they use for that glue gum? About 1/3 or more I have were just nasty that I've had to go through. I collect them because I've been able to get large numbers of them - many on the cheap. I have put them on stock sheets until I have a few months to spend on them alone. They are sorted by face type and varnish bars but other than that, no doubt I'll have a good portion of the catalog differences.
A friend told me to use something like an exacto knife to scrape the nasty glue off them but am afraid of ruining that elusive perf 9.x by 10.x by 11.X by 12.X stamp. hehehehehehe... Believe me, the different combination perfs will drive you nuts. They are as bad the glue gum itself!
Any ideas, anyone?

As far as I know, they used a glue made from animal bones and/or hides. Similar stuff is used in joinery and sets almost as hard as bone, depending on the raw material. Chemically, it is denatured protein. If exposed to warm water, it swells and softens, so that glued parts can be separated, but it is difficult to wash off completely as you have noticed. Sometimes it really seeps into the paper, and then there is little one can do.

Thank you for confirming a notion I had about the gum on those old Austrian stamps. Not only postage, but the revenues of the day used it. It can be washed off to a point and sometimes the stamp comes out fine with the look of gum on the back, but it has been cleaned. Mint ones, I wouldn't state original gum, because that would defraud the person I'm dealing with. Used ones would have to be noted they are not CTO. I have seen some fresh gum on some "used" stamps, but I would soak them if they are about to curl and bend into a disaster.
Have a good day... Tracy

I use a microwave oven to soften gum on tape, when I can't get the tape to unroll. It softens the gum then it unrolls like it was new.
5 or 10 seconds works for me.
