Hot pot spot? (4)
I believe the answer is:
kiln
'hot pot spot?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for kiln that I've seen before include "Industrial furnace" , "Industrial oven" , "Large oven for baking pottery" , "Hops or pottery cooker?" , "Large oven, for potters say" .)
