Some pottery pieces (4)
I believe the answer is:
urns
'some pottery pieces' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for urns that I've seen before include "Funereal vases" , "Large containers for tea" , "Grecian vases" , "Runs to get funeral vases" , "Tall vases" .)
