Decorated metal with engraved or embossed work (6)
I believe the answer is:
chased
'decorated metal with engraved or embossed work' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for chased that I've seen before include "Pursued at speed" , "Engraved; rushed" , "Pursued or engraved" , "Decorated metal with engraved or embossed work" , "Pursued, ran after" .)
