Hi,
This is a 12.5 inch by 2.5 inch pyrex (not plate glass) mirror blank. It was from an old project of mine; and was ground out to F5 but not figured. Unfortunately after dropping it I lost interest.
The drop caused some edge cracking in two places. The cracks are not deep and are around 1 inch square.
They probably cannot be ground out. However the mirror can be re-ground as the back of the glass is in original condition.
It is quite heavy, around 10kg as I remember.
For sale, expressions of interest sought. A new pyrex mirror blank of the same quality would be around $400. Obviously I don't expect this as one side of the blank has some damage. Would post, but pickup would be best.
Open to any offers. Looking at $150.
Cheers
Paul
