[JMS] Grinding crystals? Is an acid etch possible?

[Joe Rubin]

Maybe the quartz blank is not uniform in crystalline structure. (more 
pororous in microscopic spots than others0. We need to forward this inquiry 
to the James Millen National Laboratory  for Atomic Crystalline Structures 
or maybe a "cut and try" method. Be extremely careful when using these acids 
as some materials will act violently to immersion in acid. I can absolutely 
assure you that what I say is true even though I have no expertise in this 
field !  73  Joe  W4CBJ
