<<My pieces and my husbands pieces that have this type of glass on it have
lasted wel,l and it's been about four years now since we framed the work.
The pieces that I uni-framed have faded around the edges, but the majority
of the images are bright and true.>>
This also depends on where you live and the quality of light in your
environment. Regardless of UV framing, my framed work (all media, except
acrylic) turns ghostly in a matter of a couple years if I hang them on a
wall. However, I am in Florida and the light is very intense.
