Feature most of porcelain articles (4)
I believe the answer is:
chin
'feature' is the definition.
(facial feature)
'most of porcelain articles' is the wordplay.
'most of' means to remove the last letter.
'porcelain articles' becomes 'china' (I've seen this before).
'china' with its final letter taken off is 'CHIN'.
(Other definitions for chin that I've seen before include "Could be a double feature" , "Facial feature" , "Jutting part of lower jaw" , "Bottom part of jaw" , "Part of the face (on which one may have to take it?)" .)
