Somewhat antiquated, empty oval bowl (6)
I believe the answer is:
oldish
'somewhat antiquated' is the definition.
(I've seen this in another clue)
'empty oval bowl' is the wordplay.
'empty' means to remove the middle letters.
'bowl' becomes 'dish' (a bowl is a type of dish).
'oval' with its middle removed is 'ol'.
'ol'+'dish'='OLDISH'
(Other definitions for oldish that I've seen before include "Fairly ancient" , "Getting on in years, but not too bad" .)
