. . will steam vapor destroy stamp if used for
loosening gum ?
Only if the stamp's ink is water-based or aniline (check catalogue or ask here) Some old stamps use this type of ink and it will run or fade away in water or steam.
Steam vapor can scald you or burn you . It was used (and maybe still is0 to remove stamps without ruining / ripping apart envelopes, possibly so as to steal the stamp and sell it (years ago) without opening the mail.
Steam can remove a stamp but will wilt the paper envelope, leave gum still on the stamp and/or envelope/paper, be dangerous to work with, and be totally unnecessary really.
If you want the stamp for collecting purposes then just snip around the stamp and soak the paper in warm water or use the modern chemical methods (also dangerous for the unwary by the way).
I think that it would release the stamp from teh paper for sure, the combination of heat and moisture doing the trick, but possibly the heat would damage new ink and printings, and, as mentioned before, still not remove the gum or adhesive.
Lose/lose situation I think.
Patience is the key. See also fishing without electronics.
Rant and rave over.
