A customer i did some framing for with AR99 glass, decided to dismantle their frames at home and in doing so took out the glass and now i'm at a loss as to which side is which on the pieces that do not have printed text on. Does anyone have a method for telling one side from the other? Thanks.

Scratch the corner with a blade. the coating scratches off.

You can also look at the edges, cutting wheels leave a sawtooth type mark, this will be the side that was scored, and therefore the uncoated side

The side that has the coating on, faces the art, so it is protected when customer (if they ever do) cleans the picture when it hung
