Frost formed by the freezing of supercooled water droplets in fog onto solid objects (4)

I believe the answer is:

rime

(Other definitions for rime that I've seen before include "Ancient Mariner produced?" , "dated poetry" , "Type of frost" , "Hoarfrost" , "''The ... of the Ancient Mariner'' (Coleridge)" .)

I've seen this clue in The Mirror.
