It has an interesting link with pottery (4)
I believe the answer is:
'pottery' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'it has an interesting link' is the wordplay.
'link' can be anagrammed to 'KILN'.
But, I am not clear how this is indicated.
'with' acts as a link.
Can you help me to learn more?
(Other definitions for kiln that I've seen before include "Pottery furnace" , "Kind of oven" , "Furnace for firing bricks" , "Oven for burning lime" , "Oven for firing pottery" .)
