Made of clay from Teheran (7)
I believe the answer is:
earthen
'made of clay' is the definition.
(I've seen this before)
'from teheran' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'teheran' with letters rearranged gives 'EARTHEN'.
(Other definitions for earthen that I've seen before include "Made of baked clay, perhaps ware" , "from the ground" , "that's thrown in clay" , "Made of baked or fired clay" , "of the soil" .)
