Carbon black (4)

Ross

I believe the answer is:

soot

'carbon black' is the definition.
(synonyms)

This is all the clue.

(Other definitions for soot that I've seen before include "Carbon dust from fire" , "Black chimney powder" , "Residue from burning" , "Something stuck down the chimney" , "Deposited carbon" .)

I've seen this clue in The Guardian.
