Large vase or pot (3)
I believe the answer is:
urn
This clue is a double definition.
'large vase' is the first definition.
(I've seen this before)
'pot' is the second definition.
(I know that urn is a type of pot)
(Other definitions for urn that I've seen before include "Rounded vase" , "Run to get large vase" , "Large vessel for making coffee or tea" , "Vessel for tea or ashes" , "a large vase as for cremation ashes" .)
