Manufacture of a green incense (6)
I believe the answer is:
enrage
'incense' is the definition.
(thesaurus)
'manufacture of a green' is the wordplay.
'manufacture of' is an anagram indicator (I've seen this in other clues).
'a'+'green'='agreen'
'agreen' anagrammed gives 'ENRAGE'.
(Other definitions for enrage that I've seen before include "Cause to see red" , "Make violently angry" , "Greatly anger" , "Make someone extremely angry" , "Revolutionary group in Paris" .)
