How do I wire period sconces?

What is the difference between ormolu and gilt bronze?

Ormolu specifically refers to historical mercury gilding on bronze, common in eighteenth and nineteenth-century French workshops. Gilt bronze is a broader term that also encompasses modern electroplated finishes. Both terms describe a gold surface layer applied to a bronze base metal. Visual inspection under magnification often reveals the distinct texture of historical fire gilding.

How should I clean gilded bronze?

Dust the surface regularly with a soft, dry brush to prevent dirt accumulation. Avoid abrasive cloths, commercial metal cleaners, or harsh chemicals that strip the gold layer. Gentle wiping with a damp cloth suffices for routine maintenance. Preserving the original patina protects the historical integrity of the metalwork.
