Are these lamps converted from old vases?

Many pieces use bodies derived from decorative urns or cassolettes, but workshops frequently produced them specifically to house wiring. The distinction lies in whether the bore through the stone was planned from the outset. Examining the underside and the fitting entry points helps clarify how the conversion or original assembly was achieved.

How do I identify Louis XVI style?

Louis XVI style relies on straight lines, classical proportions, architectural swags, and leafy motifs rather than the curved asymmetry of rococo. Look for clean columnar forms and balanced mounts. This aesthetic draws heavily on excavated Roman antiquities popular during the late eighteenth century and revived throughout the nineteenth.

What is the difference between ormolu and gilt bronze?

Ormolu specifically refers to mercury gilding on bronze, a hazardous historical technique producing a distinct lustre. Gilt bronze is a broader term that can include modern electroplating methods. Both serve to enrich the metal components attached to the marble bodies.

How should I clean the marble?

Dust the stone regularly with a dry microfibre cloth and avoid harsh chemical cleaners that can etch the polished surface. Mild soapy water on a damp cloth suits most sealed stone. Keep moisture away from the metal mounts and electrical components during cleaning.
