Instructions
Cut the portion of the envelope to which the stamp is adhered, usually the upper right-hand corner of the envelope.
Fill a small pan with warm water. Place the selected portion of the envelope in the water with the stamp side facing down.
Allow the envelope to soak until the stamp detaches from the envelope and falls to the bottom of the pan. This process usually takes 10 minutes or longer.
Continue to soak the stamp for an additional one to two minutes to dissolve any remaining glue from the stamp.
Using a pair of tongs or tweezers, carefully lift the stamp out of the pan.
