Brass that looks like gold (6)
I believe the answer is:
ormolu
'brass that looks like gold' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ormolu that I've seen before include "Gold-coloured decorative alloy" , "Gold leaf" , "Gold-coloured alloy used to paint furniture" , "Gilt brass" , "Gold-like decoration" .)
