[ATM] interferomitry testing the plate glass Dan Casaro sells

[Joseph Johnston <usc@sover.net>]

Hey List,

     I have a question for those that remember the plate glass that was 
available from a gentleman in Florida several years ago and VERY cheep I 
might add. Dan bought most if not all of the 7/8" X 2 ft X 2 ft plates 
from him. This is what some if not all of his plate glass mirror kits 
are derived from. I know that there are many list members that own some 
of this exact glass and have made mirrors already. What I'm looking for 
is info about this glass. Are there any interferometric ,(spelling), 
test results out there. Someone must have tested this glass by now. What 
I have heard early on was that is of fairly high quality. But NO 
numerical figures.

     If no one has done any testing yet, is there anyone on the list 
that has the ability and would be willing to test this glass. I am 
making a lens and will continue until it's finished even if I don't get 
any figures, but it SURE would be a big help. I can supply a good test 
piece if needed.

     ANY information would be GREATLY appreciated and would be shared 
with the list. If responders wish, they may contact me off list 
initially and I'll post any results later. Thanks in advance folks.
