Tell us already!

Or give us a hint at least. Is it a mineral?

it's a commonly found crystalline solid.

 

[Engineer]

Salt.

By the gods! I'm in a picture in a picture in a picture. Awesome!

:thumbsup:

OP, WHAT IS IT? Since Engineer said salt, I will say it's sugar.

Since salt and sugar have said, I will guess Caffeine.

My other secondary guess was crystalline H2O, but I'm quite confident that is definitely not crystalline water under that microscope.

Really, I don't think it's either NaCl or Sucrose (C12H22O11 or pure C6H12O6) and caffeine is the only other crystalline solid of which I can even think that is solid.

the answer: rust

ice would sublimate under the vacuum in the SEM (unless you were in an ESEM, in which case you'd be OK i think).
