As a referee I also dislike the word "freezing" but only if improperly
used:
"The crystals were frozen in LN2" is not acceptable because it is the
outside
liquor that is rapidly cooled to cryogenic temperatures.
But the use of "freezing" used as the opposite of "melting" is fine and
does not
imply a crystalline state. Ice is not always crystalline either:
