Ceramicist to tinker about unhurriedly (6)

I believe the answer is:
potter
'ceramicist' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for potter that I've seen before include "Craftsman - dawdle - Harry!" , "One who makes ceramic objects" , "One who works with clay" , "dramatist and > author of children's books" , "wizard > snooker player" .)
