One lad taken in by copy of such enamel work (9)
I believe the answer is:
cloisonne
'enamel work' is the definition.
(I've seen this in another clue)
'one lad taken in by copy' is the wordplay.
'one' becomes 'i' (Roman numeral).
'lad' becomes 'son' (lad can informally mean a young boy).
'taken in by' means one lot of letters goes inside another.
'copy' becomes 'clone' (cloning is a kind of copying).
'i'+'son'='ison'
'ison' going inside 'clone' is 'CLOISONNE'.
'of such' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cloisonne that I've seen before include "Enamel work" , "Sort of design" , "enamelware" , "Panelled enamelwork" .)
