Curse a broken piece of crockery (6)
I believe the answer is:
saucer
'piece of crockery' is the definition.
(saucer is a type of crockery item)
'curse a broken' is the wordplay.
'broken' is an anagram indicator.
'curse'+'a'='cursea'
'cursea' with letters rearranged gives 'SAUCER'.
(Other definitions for saucer that I've seen before include "Piece of crockery, mysterious when flying" , "part of the service" , "Small dish, goes with cup" , "flying, perhaps?" , "Cup rest" .)
