Made of baked clay (7)
I believe the answer is:
earthen
'made of baked clay' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for earthen that I've seen before include "(Of pot) made of baked clay" , "Made of baked or fired clay" , "from the ground" , "Like many pots" , "of the soil" .)
