I'm selling two Pyrex 7740 8-inch mirror blanks that I purchased
many years ago. The first is a Corning molded blank which is tapered
and has a raised lip on the backside and a very slightly raised
lip on the front side about 1/4 inch wide around the perimeter that
will need to be ground off. I'm asking $85 for this one because
of its rarity and condition (never used and new in the original
packing material).

The second is a United Lens blank that has a small chip on the
perimeter of the front side that will not affect the finished
mirror surface. Both front and back sides are flat. A good
portion of the small chip, which is 1/8th of an inch across,
should be eliminated with the required chamfering during the
grinding operation. I'm asking $70 for this one, which is
also new and never used.

Both mirror blanks are full thickness at 1 3/8 inches. Each mirror
blank weighs approximately 5.5 pounds. The asking price for both
includes the cost of shipping to anywhere in the continental United
States via USPS Priority Mail in a Large Flat Rate Box and will be
well packed.

Thanks for looking at my advertisement.
