I've not ever heard of the glass your all talking 
about..I may consider it though but I've had mine 
in "normal" glas frames for a year(Two of them)
and only experienced a little line fadeing from 
my tenchi cel..though on my slayers one I've 
noticed little or next to none and they've been 
up for a year..

but I framed these when i knew VERY little about 
cel collecting..

I like to enjoy my cels though..not leave them in 
a book to collect dust..:/ i orry about line 
fades though now..Eff..But my room is very light 
and it has a constant tempture through the 
seasons..maybe thats why the two i had in frames 
didn't have much damage over the year.
