I'm selling a United Lens Company 7740 Pyrex 6-inch mirror blank
that is full thickness of 1 inch. No edge chips of any significance.
The front surface has never been used; however, I used this one
when I was making a 6-inch mirror several years ago to practice
on the side and back of this extra mirror blank using a diamond-tipped pen
to write my name and focal length. There are markings all over-perhaps
they can be blancharded off. You can see some of these in the photograph
of the back side of the mirror. If this doesn't bother you, could
be used for a nice telescope mirror or even a tool. I'm asking
$30.00 and I'll ship to anywhere in the continental United States
via USPS Priority Mail.
Thanks for looking at my advertisement.
