I have #84 in orange red. On this one I can see a hint of oragnge in the corners. What would cause a color shift like this? Or is it another issue that I have overlooked in Scott? Thanks for your input.
Looks like your stamp sulferized (frequently called "oxidized). That color ink wasn't very stable, so this happened somewhat often. If soaked in hydrogen peroxide (3%, use a new bottle), it will turn the color back to about what it was. The color will likely start changing right away - carefully swirl/move it around a bit with tongs. 30 seconds to a minute or so should do it. If not, put it in a bit longer. Be sure the rinse the stamp in lukewarm clean water a few times, then let it dry in a drying book. Should do the trick!
Thanks for your advice! I have not had the opportunity to get out to buy hydrogen peroxide, but eill let you know when I have tried your advice! Thanks again, Mel
