Glossary

Terms used in our catalogue descriptions, briefly explained.

Okimono
A Japanese decorative sculpture, literally a 'placed thing' — an ornament for display in an alcove or on a cabinet, most often in bronze, ivory or wood, and a specialty of the Meiji era.
Tomobako
The original fitted wooden box made for a Japanese work of art, frequently inscribed with the title of the piece and signed or sealed by the artist. An important part of a work's documentation.
Meiji era
The reign of Emperor Meiji, 1868–1912 — a period of extraordinary technical brilliance in the Japanese decorative arts, when leading workshops produced metalwork and cloisonné of unmatched refinement for international exhibitions.
Shibuichi
A Japanese alloy of copper and silver, patinating to subtle grey-brown tones. Prized for sword fittings and later for the inlaid surfaces of Meiji metalwork.
Shakudō
An alloy of copper with a small proportion of gold, patinated to a lustrous blue-black. Used with gold and silver inlay to painterly effect in fine Japanese metalwork.
Patina
The surface colour and texture a metal object acquires through deliberate chemical treatment and age. Original patina is fragile and precious — it should never be polished away.
Signature / seal
Japanese works are commonly signed with chiselled characters or inlaid seals, often naming the artist and studio. Signatures are compared against recorded examples as part of cataloguing.
Provenance
The recorded history of a work's ownership — earlier collections, auctions, exhibitions and publications. Documented provenance supports authenticity.
Attribution
Qualified language for authorship: 'signed' means the work bears the artist's signature; 'attributed to' expresses a considered but not certain opinion; 'school of' or 'workshop of' indicates production in the artist's circle.
Bidri ware
Indian metalwork from Bidar in the Deccan: a blackened zinc alloy inlaid with silver or brass in floral and geometric designs, at its finest in the 17th and 18th centuries.
Company School
Indian paintings made for British patrons during the East India Company period, typically watercolours of natural history, trades and topography, blending Indian technique with European taste.
POA
'Price on application' — the price is available on request rather than published. Simply quote the work's stock number when enquiring.
Condition report
A written account of a work's physical state: wear, losses, repairs and restoration. We prepare one for any work on request before purchase.
