[meteorite-list] Slump glass meteorite protection/display

[STARSANDSCOPES at aol.com]

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 1½ cents  (allowing for currency conversion fees depending on where 
you are in the  world.)
