Ice Bucket

Silver & Metalwork

An Ice Bucket is a lidded vessel, typically silver, silver plate or glass, used from the 19th century onward to keep bottled wine or champagne chilled at the table. Antique examples are often campaign-style with carrying handles or fitted with tongs.

Ice Glass

Glass

Ice Glass, also called craquelle glass, has a deliberately crackled surface texture achieved by plunging hot glass into cold water before reheating and shaping, giving it a frosted, ice-like appearance popular in 19th-century decorative glassware.

Imari Porcelain

Ceramics & Pottery

Imari Porcelain is Japanese export porcelain, named after the port of Imari, decorated in a distinctive palette of underglaze blue with overglaze iron-red and gilt. Produced from the late 17th century, it was widely imitated by European factories including Worcester and Derby.

Import Marks

Collecting & Buying Guides

Import Marks are stamps applied to goods entering a country, such as "Made in England" or country-of-origin marks required by 19th and 20th-century trade legislation. They help collectors date and authenticate ceramics, silver and other antiques.

Inkstand

Silver & Metalwork

An Inkstand is a desk accessory, often silver, brass or pottery, combining inkwells, a pen tray and sometimes a taper stick or pounce pot on a shared tray or base. Georgian and Victorian examples are especially prized by collectors of desk antiques.

Inkwell

Silver & Metalwork

An Inkwell is a small vessel for holding ink, made in materials ranging from glass and pottery to silver and bronze. Antique inkwells were often fitted with hinged lids to prevent evaporation and frequently formed part of a larger inkstand.

Inlaid Furniture

Furniture

Inlaid Furniture is decorated with pieces of contrasting wood, metal, ivory, mother-of-pearl or other materials set into the surface to form patterns or pictorial scenes. The technique flourished in cabinet-making across the 17th to 19th centuries.

Inlay

FurnitureMaterials

Inlay is a decorative technique in which material is set into a recess cut into a wooden or metal surface, flush with the surrounding surface, to create pattern or ornament. It differs from marquetry, in which the whole veneer surface is built from applied pieces.

Inro

Decorative Arts

An Inro is a small, multi-compartment Japanese case, traditionally lacquered, worn suspended from a kimono sash and secured with a carved toggle known as a netsuke. Antique inro are collected for their fine lacquer and inlay work.

Intaglio

Decorative Arts

Intaglio describes a design cut or engraved into a hard surface, most commonly a gemstone or seal, so the image lies below the surface plane, the reverse of a cameo. Antique intaglio seals and rings were used both decoratively and for sealing documents.

Intarsia

Furniture

Intarsia is an Italian Renaissance form of wood inlay in which shaped pieces of veneer are fitted together like a mosaic to create pictorial or geometric designs, often depicting architectural perspectives, still lifes or landscapes on cabinet doors and panels.

Ionic Order

Architecture

The Ionic Order is one of the classical orders of architecture, identified by the scroll-like volutes of its column capitals. It appears frequently in Georgian and Neoclassical furniture and architectural detailing, including pediments, columns and fire surrounds.

Iridescent Glass

Glass

Iridescent Glass has a rainbow-like surface sheen created by treating glass with metallic oxide fumes while still hot. The technique was popularised by Tiffany's Favrile glass and by makers of Carnival Glass in the early 20th century.

Ironstone China

Ceramics & Pottery

Ironstone China is a dense, durable earthenware developed in early 19th-century England as a hard-wearing alternative to porcelain. Patented by Charles James Mason in 1813, it was widely used for dinner services and remains popular with collectors for its weight and strength.

Islamic Ceramics

Ceramics & Pottery

Islamic Ceramics encompass pottery traditions from the Middle East and North Africa, celebrated for lustreware, cobalt-blue underglaze painting and geometric or calligraphic decoration. These techniques strongly influenced European maiolica and Iznik-inspired wares.

Italianate Style

Ivorine is an early synthetic imitation of ivory, made from cellulose compounds, used from the late 19th century for piano keys, cutlery handles and small decorative items as a cheaper, legally unrestricted alternative to genuine ivory.

Ivory

Materials

Ivory is the dense dentine material from the tusks of elephants and other animals, historically carved into figures, netsuke, fans, piano keys and furniture inlay. Trade in antique ivory is now heavily restricted by law, and provenance and age documentation are essential for sale.

Ivory Carving

Decorative ArtsMaterials

Ivory Carving is the art of shaping ivory into figures, reliefs and decorative objects, practised across many cultures from medieval Europe to Qing dynasty China and Edo period Japan. Fine antique carvings are valued for their intricacy and age-related patina.

Iznik Pottery

Ceramics & Pottery

Iznik Pottery is Ottoman Turkish ceramic ware produced from the 15th to 17th centuries in the town of Iznik, prized for its vivid underglaze cobalt, turquoise and sealing-wax red floral designs on a white ground. It strongly influenced later European decorative ceramics.
