ceramic market
A market where ceramics and pottery are sold. 瀬戸物 (setomono) is a general term for pottery, named after the Seto region.
I went to the ceramic market on the weekend and bought a new rice bowl.
Refers to pottery or ceramics in general, while 瀬戸物市 specifically means a market where such items are sold.
Also means pottery market, but 陶器 (touki) is a more formal term for ceramics, whereas 瀬戸物 is a colloquial term with historical Seto association.
Compound of 瀬戸物 (setomono, 'pottery', from Seto region + 物 'thing') and 市 (ichi, 'market').
