Original claim a March girl’s put in for pottery (8)
I believe the answer is:
majolica
'pottery' is the definition.
(I know that majolica is a type of tin-glazed pottery)
'original claim a march girl's put in' is the wordplay.
'original' indicates anagramming the letters.
'march girl' becomes 'Jo' (Jo March, character in the novel Little Women).
'put in' indicates putting letters inside.
'claim'+'a'='claima'
'claima' with letters rearranged gives 'malica'.
'malica' enclosing 'jo' is 'MAJOLICA'.
'for' acts as a link.
(Other definitions for majolica that I've seen before include "Glazed porous pottery" , "Highly-decorated style of earthenware (J, not I)" , "Glazed earthenware - a Clio jam (anag)" , "Highly decorated glazed earthenware" , "Type of highly decorated earthenware" .)
