How do I identify a true bronze lamp from spelter?

True bronze is heavier, colder to the touch, and exhibits a more resonant sound when gently tapped than zinc-based spelter. Additionally, bronze permits sharper chased details that do not blur. Examining the underside or concealed interior areas often reveals the distinct reddish-brown tone of bronze compared to the greyish metal visible beneath worn plating on spelter pieces.

What periods do these lamps usually come from?

The pieces span the nineteenth century through to the mid-twentieth century, encompassing Victorian, Edwardian, art nouveau, and art deco movements. Mid-nineteenth-century items often favour ornate revival styles. Later twentieth-century examples shift towards stylised figures and streamlined marble or onyx combinations reflecting changing modern tastes.

Are these lamps wired for modern use?

Many period lamps have been re-wired at various points in their history to comply with contemporary electrical standards. Buyers should inspect the internal wiring upon acquisition to ensure safety. Original brass lamp holders are sometimes retained for authenticity, though modern flexible cords and plugs are standard additions for everyday domestic use.

How should I clean a vintage bronze lamp?

Dusting gently with a dry, soft microfibre cloth is sufficient for routine maintenance of patinated bronze surfaces. Avoid aggressive commercial metal polishes that strip away historical patination. Marble or onyx bases can be wiped down with a damp cloth and dried immediately to prevent moisture rings on porous stone.
