Things You'll Need
Instructions
Remove stamps from envelopes, leaving a 1/2-inch to 1-inch border of paper around the stamp.
Sort stamps by gum type. Water-soluble stamps are likely to be from 2000 or earlier, and the perforations on the sides are rounded indentations. Self-adhesive stamps' "perforations" vary in shape.
Sort out any stamps on envelope paper colors other than white. Red paper can bleed into the water and turn all the stamps in the pan pinkish; stamps on cardboard can take a long time to soak off, if corrugated; and stamps that came on envelopes filled with recycled newsprint in the inside should also be done separately. They're a mess.
Fill a shallow pan, such as a pie plate, broiler pan or 9-by-13-inch pan, with warm water for water-soluble stamps and hot water for self-adhesives. Boiling water will fade them, however.
Place a single layer of one type of stamp in the pan.
Stir the stamps in the water. Use the stamp tongs to pick up lick-and-stick stamps that have floated free, and move them to a paper towel, face down. Some stamps may need to have their paper gently lifted off. Self-adhesive stamps may not come off the paper at all, no matter how long they sit there. Some may come off the paper but retain their glue. Don't fuss with them until at least five minutes have passed. If you have to tug at the paper, the front will likely crack.
Blot the freed stamps with a piece of paper towel.
Move the stamps, face up, to a glossy drying book page. Work back to front in the book. When a page is full, prevent stamps from curling by lowering the next page on top.
Close the drying book, and place a heavy book on top of it until tomorrow, when your stamps will be crisp, flat and ready to archive in an album or storage envelope.
