If anybody has silver mirrored tempered glass let me know if there were any problems with it.I just finished a small job and had some stain spots show up.I am thinking it had something to do with the tempering.My tests on regular glass came out fine.

The main problem with mirroring tempered glass is that in the tempering process the glass can warp, causing you to get a carnival mirror. I woudn't think there would be any contaminants on tempered glass that wouldn't be removed with the normal cleaning process used for mirroring...but I don't know...

Roderick,
I have noticed that tempered glass can tend to have contamination from the atmosphere of the oven baked into it's surface. Often it has what seems to be the combusted residue of an oily vapor deposited into the surfaces.
After cleaning off that residue, you can hold the glass at an extreme angle to a light source and still see a rainbow like effect reflected on its surface.
Also, unless the glass is "tong tempered" you will see faint indentations where the heated glass passed over the conveyor rollers of the oven.
