How do I date a marble lamp?

Examine the wiring, mounts, and overall style to establish an approximate period. Art Deco pieces from the 1930s often feature geometric steps and figural novelties, whereas nineteenth-century examples lean towards classical columns and urns. The type of metal mounting and the finish of the bronze or brass components also offer clues to the workshop's active era.

Are these lamps safe for daily use?

Most older lamps require professional rewiring to meet modern electrical safety standards. A qualified electrician can replace aged internal cords while preserving the original stone and metal exterior. Check that the brass fittings and weighted bases remain secure before plugging them in.

How should I clean the marble base?

Dust the stone regularly with a soft, dry cloth to prevent grime accumulation. Avoid harsh chemical cleaners or abrasive pads that can scratch the polished surface. For stubborn marks, use a damp cloth with mild soap, then dry the stone immediately.
