I have the paper so if anyone actually wants to specify an actual firing temp. A test can be performed.

I would think that the glaze will stick to the fiber for exactly the same reasons it sticks to a kiln shelf.  I cannot imagine anything in the fiber paper that would prevent that.  Glaze will stick to every other fiber product I know of, so I do not see how the paper would be different.  If glass is slumped on a kiln shelf or over a high-silica refractory form, it does not stick unless it is overheated and becomes tacky, and glazes always become tacky in a normal firing.

I know I have to check out the temperature that it will hold up under, but only if people have had success firing with fiber paper.
