Gaffer Glass blows these bowls or whatever you want with their photosensitive glass formula. Look at the above attachments.
my 1000 f degree oven is on the fritz, otherwise, i found this interesting!

I live just down the road from Gaffer Glass and apparently I'm the only one who buys it.
They only ever made one batch of photosensitive and I've just bought the rest of what they had left.
I guess it is how one determines what "durable" means. Glass is pretty fragile, compared to the typical film base.
Can it survive a nuclear strike or large meteor earth collision? If not, it is no more durable than a photographic print produced just before the disaster.
