Kitchen utensil made of old nacre (8)
I believe the answer is:
colander
'kitchen utensil' is the definition.
(I've seen this before)
'made of old nacre' is the wordplay.
'made of' is an anagram indicator.
'old'+'nacre'='oldnacre'
'oldnacre' with letters rearranged gives 'COLANDER'.
(Other definitions for colander that I've seen before include "kitchen utensil" , "One strains" , "Perforated bowl" , "found in the kitchen" , "Culinary strainer" .)
