Came with my 10x10 Fotar enlarger. Slight texture on one side so I believe it's anti-newton glass. Measures 10x10 but the corners are clipped so far that an entire 8x10 neg can't be projected! They came from a lab that specialized in automotive work before photoshop came along. WTF?
I have a bunch of these in 4x5 size as well.

Might be a diffuser for the light source, my Eastman 5x7 had one.
Or it could be heat-absorbing glass, if it came from just below the light source.
I know it's not a diffuser but I don't understand why they'd clip the corners so far in!
Is it because car shooters never used the full frame?
It has to be AN glass. Heat absorbing glass is thicker and totally clear and placed immediately under the light source. The AN glass is used with the texture in contact with the negative.
Pin registration system that uses holes in the film itself?
The neg carrier does have registration pins but i couldn't pullmit frommthe machine since it is currently stored in a giant plywood box. Still doesn't explain why the corners are clipped so far in. Makes me angry.
