Sparkle you can see in silver vessel (5)
I believe the answer is:
verve
'sparkle' is the definition.
(thesaurus)
'you can see in silver vessel' is the wordplay.
'you can see in' indicates a hidden word.
'VERVE' is hidden within 'silver vessel'.
(Other definitions for verve that I've seen before include "Life" , "Sparkling enthusiasm" , "Great liveliness or enthusiasm" , "Dashing enthusiasm" , "Animation" .)
