Stone again powdered in incense (10)
I believe the answer is:
antagonise
'incense' is the definition.
(to antagonise someone is to annoy or incense them)
'stone again powdered' is the wordplay.
'powdered' indicates an anagram (letters get pulverised or crushed).
'stone'+'again'='stoneagain'
'stoneagain' with letters rearranged gives 'ANTAGONISE'.
'in' is the link.
(Other definitions for antagonise that I've seen before include "Cause opposition" , "Bug" , "Create hostility" , "Make an enemy of" , "Provoke hostility" .)
