JL. look at the post on mounting a medal at the pinned area. The colors are not 100% stable. If you place under a glass or plexiglass use UV ultra violet glass, or plexiglass. Make sure the material backing is archival safe to use not a plastic or a wood backing. Paul

Do light bulbs produce any significant quantity of UV's?
I have put the flag between two pieces of regular glass, with a recently printed photo of the original owner also between the pieces of glass. I have put the pieces of glass in a dark area of presentation case, in a room with no direct sunlight (sheets over all windows). Do you think it is safe?
I cant post a photo as my membership ran out, but an old photo of the display case where the flag is, is visible here, in post 14 http://dev.wehrmacht-awards.com/foru...highlight=fssf

IMO use the UV light class if you can see the frame and what is in it with daylight or artificial light then some UV is hitting it, these things are very sensitive and well worth the price of the protective glass to protect.

Jean. All light both artificial and natural light emit some amounts of UV rays. Some rays are shorter and not as bright as others light sources. The weaker UV rays would take a bit longer in time to damage an item. It’s always best to use either UV glass, or UV Plexiglas it a bit more expensive than plain old window glass. I hope that you did not sandwich the flag between to pieces of glass with out a space between the flag and glass? You could be trapping moisture if there is no barrier. Yes, jhodgson is correct even ambiant light will damage items.
If you have ever gone into a museums gallery, and it dark. Some times the gallery 's light goes on when a person enters a gallery. This is done to limit light exposure to an item. PaulLast edited by Paul R.; 09-17-2008, 07:14 AM.Comment

Where can this UV glass usualy be bought? I have never seen any here in France. The two pieces of glass I used are from two picture frames I bought at the supermarket.
The flag is sandwiched between the two pieces of glass, but there is a small space as the flag is rather thick, and nothing closing the sides of my improvised frame, so I doubt humidity should be a problem.

You may want to try art/picture frame shops, or any art supply shops. Also try hobby stores or online companies. PaulComment

Thanks for the hints. I will try finding some, and will put a piece of paper in front of the flag in the meatime to keep it in the dark.
Is this anti UV glass really effective though?

Jean. Yes, the UV glass is very effective. Of course no class works 100% UV glass is rated about 98%. Most art museums that use glass covering for some of there art us the plexi UV glass. Make sure the paper around the flag is a acidfree material. PaulComment
