Made of baked clay (7)
I believe the answer is:
earthen
'made of baked clay' is the definition.
(I've seen this in another clue)
This is all the 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" .)
