Fair market value$400 – $1,100
Mid-point of Japanese suiban auction results ($250–$750) and current retail asking ($845). The weight, the dark even patina and the cast seal push it toward the upper half. The value is open-ended upward only if a specialist reads the mark as a genuine early Chinese foundry seal.
This is the biggest and heaviest piece in the collection, and the "big heavy bronze base". It isn't a base, though: it's a vessel. It is a long, shallow rectangular basin with straight sides. A rolled, slightly everted lip sits over a band of about twenty raised round bosses (stud or "rice-grain" ornament) on a finely diapered ground. The ends carry stylised kui-dragon C-scroll handles, and it stands on four bracket feet shaped like ruyi clouds.
Outside, the patina is smooth chocolate-brown, darker on the high spots, the kind Japanese founders applied chemically and then waxed. Inside, the surface is paler and golden with green verdigris where water has stood (P05, P14). That is a good sign: the basin was actually used for flowers or bonsai.
In Japan a vessel of this shape is a suiban (水盤) or doban (銅盤). It is a water basin for ikebana in the moribana style, where flowers stand in a pin-holder in shallow water. It is equally a display tray for bonsai or suiseki (viewing stones). Westerners have always called them "jardinières" or "planters", and in the trade they sell as "bonsai pots". The boss band and the dragon handles copy Chinese Ming-dynasty bronze censers, and Japanese buyers of the period prized that Chinese literati look.
The important feature is underneath. Cast into the base is a raised square seal of four characters in seal script, in two columns (P04, shown enlarged in the second and third images). Turned and enlarged, the right-hand column reads best as 宣 over 德 and the left as 年 over 製. That gives 宣德年製, "made in the Xuande reign". The Xuande emperor (reigned 1426–1435) is legendary for the bronze censers cast in his reign, and Chinese and Japanese founders put his mark on bronzes for the next five hundred years as homage. A Xuande mark on a vessel like this is almost never a date; it is a statement of style. It is an "apocryphal" mark, honest by the conventions of the time, and should be catalogued as "Xuande mark, later". The reading itself is only medium-confidence.
Why we lean Japanese rather than Chinese: the casting is very even and sharp, the exterior patina is uniform and applied rather than accumulated, the seal plaque is flat and crisp, and the proportions (long, low, with small separate feet) are typical of Takaoka export suiban that borrowed a Chinese reign mark. A Chinese late-Qing censer of this form would more likely be squarer, deeper and heavier-walled. A small paper or foil label shows on the side in the night photographs. Keep it, because old dealer labels add provenance.
Other things it could be
- Chinese late-Qing or Republic rectangular censer or jardinière with an apocryphal Xuande mark, copying a Ming fangding
- The seal may be a Japanese foundry seal in a square cartouche (e.g. a Takaoka maker) rather than a reign mark
- Mid-20th-century Japanese export copy, worth about half as much
What points that way
- Rolled rim over a boss band on a diaper ground
- C-scroll kui-dragon end handles; four ruyi-cloud bracket feet
- Four-character seal-script mark in a raised square, cast on the base
- Smooth applied brown patina outside; water staining and verdigris inside
- Very heavy for its size, so cast bronze rather than spelter
Check in person
- Photograph the base mark straight down in raking light, and ask a Chinese reader or an Asian-art auction house to confirm 宣德年製
- Measure length × width × height and weigh it; serious suiban of 18–24 in weigh 15–30 lb
- Check whether the seal is cast in one with the base or set in as a separate plaque
- Do not polish or scrub; the patina is the value
