I was just asked if I was Army. No, I am the proud dad of a son who is Army
EOD (Explosive Ordinance Disposal). He is a bomb guy.
 
I am boring by comparison! Spending my nights looking at thin sections.
(Thanks to Jeff Hodges and Greg Hupe, my thin section benefactors)

Cool, The army says HUA (Heard, Understood and Accepted), well HUA.
However, I know the Higgins (famous for slump glass) had all those issues
but were
able to overcome them in many materials. Slow heating and cooling can
solve
a lot.

Please keep in mind I am not vested in this idea, just wondering. Tom

Tom,

I would be very afraid of the olivine cracking (at the least) -- and at
the worst, cracking and crumbling out of the iron, leaving you with a
falling-apart mess sandwiched between two layers of cracked glass. The
glass is likely to crack due to the stress of the heating and cooling too.

Better you should not heat it, but either use the dessicant as suggested in
the article, or perhaps displace the air with a dry, inert gas like
nitrogen, and sealing it in.

That's my 1? cents (allowing for currency conversion fees depending on
where
you are in the world.)
