I don't know the age of this censor but I would say anywhere from the early 1800s back to the Sung dynasty (960-1279 A.D.) when there was a renewed interest in the antique bronze forms. The white porcelaneous stoneware body has been fired to give a vitreous surface and then the outside was cold painted (by hand) in blues, tans, and pinkish red. The form mimics the bronze censors (Tings or Dings) of 1000 B.C. with molded fretwork geometrics in low relief around the body. The most striking and unusual touch is the feet- figural representations of an old man's head with his long beard forming the base. The top has the classic two U-shaped handles.
The vessel stands 6" (15 cm) high to the top of the handles and is 4" (10 cm) at its widest. Weight is 1.8 lbs. Condition issues include wear of the paint especially on the edges and high spots and there is a very tight hairline crack on the inside near one of the handles, hardly noticeable and I just saw it now while examining the piece with a loupe.
This piece may have once been intended for a scholar's desk.
