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.
