Potter about before armistice arranged (10)

I believe the answer is:

ceramicist

'potter' is the definition.
('ceramicist' can be a synonym of 'potter')

'about before armistice arranged' is the wordplay.
'about' becomes 'c' (abbreviation for 'circa'**).
'before' means one lot of letters go next to another.
'arranged' indicates anagramming the letters.
'armistice' is an anagram of 'eramicist'.
'c'+'eramicist'='CERAMICIST'

I've seen this clue in The Telegraph.
