Stamps R Art

Here's a question for you...

If you expose a typical 19th century stamp for 8 hours a day under the lights of a typical room/office, how many years before the stamp will begin to show signs of fading?

Mark Wardas has got the answer to that and a lot more on his Stamps R Art Web site.

Devoted to the education of stamp collectors on issues of philatelic preservation and care, the site offers a lots of good information on the other 4 Ps in Philately -Paper, Plastic, Preciptiation, and Photons.

According to Mark, the answer to the above questions depends on how much previous exposure to UV and VISIBLE light the stamp has already experienced. In extreme cases the stamp could begin to fade with very little further illumination. If the stamp had never been exposed to UV or VISIBLE light, it probably would not begin to fade until it had been illuminated for about 10 years.
