What is the difference between a cassolette and a censer?

A cassolette is a reversible vessel that acts as either a covered urn or an incense burner, often made of marble mounted with gilt bronze. A censer is specifically designed to hold burning incense, usually featuring a pierced cover and a stable bowl form without the dual-purpose reversible function.

How do I distinguish French and Asian burners?

French pieces from the nineteenth century frequently utilise ormolu mounts paired with coloured marble, onyx, or patinated bronze, often reflecting neoclassical revival styles. Asian pieces rely on cast bronze bodies decorated with cloisonne enamel, champleve, or hardstone inlays, following distinct cultural traditions such as the Meiji period or Qing dynasty.

Were these items meant to be used?

While originally created to burn incense or perfume interior spaces, many surviving examples served primarily as decorative garniture sets and mantel ornaments. Their physical condition often reflects this ornamental role, preserving delicate gilding and enamel work that might otherwise show heavy wear from frequent functional use.

How should I care for gilt bronze and marble?

Dust surfaces gently with a soft, dry cloth to prevent the accumulation of grit on the delicate gilt bronze and polished stone. Avoid using abrasive cleaners, polishes, or chemical solvents, as these can strip the gold leaf or damage the underlying patination and marble.
