For the last grain in your presentation MS G619, you mention that there is some temperature cycling. Do you know what causes the temperature to fluctuate?

G506 seems have more sub-grains with different polytypes, similar to the X grains, but the other two mainstream grains are much more uniform in structure. What might cause this?

Can you predict how the subgrains, defects, voids, etc., affect the IR spectra, knowing how they affect the Raman spectra? Could this be modeled given how unsystematic the Raman spectra effects appeared?

Very nice and clear talk. Some of your early described subgrains were very angular and looked like sharp fragments. Would you care to comment on such morphology and what it might tell you?

In your grains with voids and lots of stacking faults, what exactly does "rapid crystallization" mean in the context of an expanding supernova shell? How fast is fast?
