How do I clean alabaster lamps?

Dust alabaster gently with a dry, soft cloth to prevent moisture damage to the porous stone surface. Avoid harsh chemical cleaners that strip the natural mineral finish. For stubborn marks, use a barely damp cloth followed immediately by dry buffing. Keep electrical components away from water during any maintenance.

Are these lights wired for modern use?

Many vintage fixtures retain older wiring that requires professional rewiring to meet current safety standards. A qualified electrician can replace internal cords while preserving original sockets and switches. Check the lamp base for access holes where wires pass through the stone body. Ensure the weight of the stone is properly supported by appropriate table surfaces and heavy-duty ceiling hooks.

How do I date an onyx lamp?

Examine the metal mounts, switches, and plug types for manufacturing clues associated with art deco or mid-century design periods. Neoclassical and Victorian columns often feature heavier bronze trim and distinct patination. Compare the turned shape of the onyx body against documented styles from the early twentieth century. Maker marks stamped onto internal brass fittings also provide chronological reference points.
