How do I clean these metal sconces?

Dust gently with a soft, dry brush to prevent accumulation in the recesses of the cast cherubs and foliate scrolls. Avoid abrasive polishes that can strip away the historic gilt bronze or ormolu surface. Keep moisture away from the metal and any older electrical wiring to preserve the patina. A microfiber cloth is usually sufficient for routine maintenance.

How do I distinguish French from Italian pieces?

French pieces often display the refined chasing and precise casting typical of nineteenth-century Parisian ateliers working in the Louis XIV or Rococo Revival manner. Italian examples frequently utilise carved giltwood or Murano glass elements alongside more exuberant Baroque styling. Regional differences also appear in the choice of wood substrates and the composition of the gesso underneath the gilding. Examining the backplate fixings can provide additional clues regarding origin.

What is the difference between brass and ormolu?

Ormolu consists of cast bronze treated with a gold and mercury amalgam, resulting in a deep, warm golden finish with exceptional light-reflecting qualities. Brass is a copper and zinc alloy that tends to have a brighter, yellower metallic tone and is generally associated with later or less costly production. Weight and surface texture help differentiate the two materials upon closer inspection. Ormolu exhibits the finer detail characteristic of chased bronze work.
