China or Chile on the outside breaking clear (9)
I believe the answer is:
porcelain
'china' is the definition.
(I've seen this before)
'or chile on the outside breaking clear' is the wordplay.
'on the outside' suggests removing the centre.
'breaking' means one lot of letters goes inside another.
'clear' becomes 'plain' (synonyms).
'chile' with its middle removed is 'ce'.
'or'+'ce'='orce'
'orce' placed within 'plain' is 'PORCELAIN'.
(Other definitions for porcelain that I've seen before include "Fine earthenware" , "Crockery" , "Fine white ceramic" , "Fine ceramic ware" , "Form of ceramic" .)
