[meteorite-list] Baking a fresh meteorite

[MexicoDoug at aol.com]

Marco,

For an unknown meteorite that has got to be terrible advice, wouldn't you 
think?  The mindset of "a stone" vs. an unknown sample of the universe, is 
probably part of the problem.  All the "natural" lighter components would be 
volatilized, and there is alway the risk of microscopic sintering.

I doubt NASA treats their returned samples blindly like this, perhaps the 
best advice would be to seal, with the minimum of air, as hermetically possible 
and put in the coldest freezer available ... to simulate the best shot at outer 
space conditions ... like most biological and chemical analyses require.

I remember reading about Bob Haag picking up an organic meteorite in 
Murchison Australia in Rocks from Space by Richard Norton, about a smart woman who had 
sealed it in a pickle jar or something like that, and everyone was very 
impressed by the odors that were captured.

Now if the meteorite is known to be an common OC and fell through the roof 
into a fish tank, perhaps such a scenario might lend to a little baking...

Saludos, Doug
