Were these candelabra converted to electricity?

Some historical examples are adapted into table lamps by running wiring through the central column. This conversion was often carried out later in the twentieth century to suit modern domestic lighting needs. Checking the base or underside reveals whether the original threading or candle sockets remain unaltered. Unconverted pieces retain their original configuration for holding wax candles.

How do I date a nineteenth-century piece?

Examine the weight, casting method, and decorative style to narrow down the decade of production. Nineteenth-century items often display characteristics of specific revivals such as Louis XVI, Rococo, or Gothic styles. Look for assembly marks, screw types, and wear patterns on the underside of the base. Hand-cut threads and heavy bronze casting generally point towards earlier Victorian or French manufacture.

What is the difference between brass and ormolu?

Brass is an alloy of copper and zinc, possessing a natural yellowish metallic tone throughout its structure. It forms the solid structural base for many utilitarian and decorative objects. Ormolu refers specifically to gilt bronze where a gold mixture is bonded to the surface of the bronze metal. This creates a deeper, more lustrous golden appearance distinct from standard polished brass.
