Re: ATM Corning optical glass

If you can, find any catalogs of glasses that they may have around and see
if you can make copies of it.  There's always the need to find out what some
of this old glass that has been floating about and not much is known about
it anymore as those who had catalogs (professional opticians mostly) have
thrown those catalogs out and there really isn't much of what the glasses
were called or their standard indices were.
As to the catalogs, the specs of the glasses are more important that all the
description of the specs (I don't have to see another copy of how the glass
is speced in temp, melt temps and other such things) are.
I've got a '60 era Bausch and Lomb glass set on my website thanks to one guy
that had it and the one thing that is missing is the common names that the
glasses had (they were all defined by the glass number) and tho I have found
the names for some of them, I hven't gotten that many and thus haven't put
in the names that other makers used for the glass spec.
