How do I date a brass column lamp?

Examine the construction methods, base weights, and switch mechanisms used on the fitting. Earlier nineteenth-century examples often show hand-finishing marks beneath the base. Stylistic shifts also help narrow the period, moving from heavy Georgian proportions toward ornate Victorian silver plating and later Edwardian simplicity.

Were these originally electric lamps?

Almost none of these pieces started life with electric wiring. The majority began as oil lamps, heavy candlesticks, or fluid lamps before later conversion. Conversion work is standard for lighting of this age, allowing period columns to function safely with modern electrical standards.

What is the difference between brass and ormolu?

Brass is an alloy of copper and zinc, polished to a warm metallic sheen that darkens naturally over time if left unlacquered. Ormolu involves a layer of gold applied to bronze. Ormolu provides a brighter, more luxurious golden finish associated with French Empire pieces, whereas standard brass offers a domestic utility aesthetic.

How do I clean a silver-plated lamp base?

Silver plate requires gentle treatment with a non-abrasive cloth and specialist polish to preserve the thin metal layer over the base brass. Avoid harsh scrubbing that wears away the plating at high points. Leave a light patina in recessed fluting to maintain the antique character of the column.
