How to Care for Ormolu and Gilt-Bronze Mounts

Ormolu usually refers to fire-gilded bronze, though the term is often used broadly. Historic gilding is thin and cannot withstand routine metal polishing.

Why the material is vulnerable

Abrasives remove gold and soften chasing. Moisture and cleaning residues collect behind mounts, while loose fixings can tear veneer.

What to inspect

Identify gilding, lacquer or later paint.
Look for copper-alloy corrosion.
Inspect mount edges and fixings.
Record redundant holes and replacements.
Check whether movement comes from the carcase.

Photograph condition and identify every material before cleaning. Check hidden and protected areas; damage often begins at edges, fixings and interfaces between unlike materials.

Safe care

Dust with a soft brush only when stable. Handle by the furniture, not mounts. Loose or corroding elements require coordinated metal and furniture conservation.

Start with environmental correction and the least interventive method. Use clean barriers, soft tools and controlled suction only where the surface is stable. Stop if colour, flakes, fibres or corrosion products move.

Avoid

Brass polish or ammonia.
Removing mounts unnecessarily.
Tightening screws against fragile veneer.
Re-gilding without documentation.
Scrubbing recesses.

Monitoring and specialist help

Inspect frequently handled and projecting mounts. Maintain stable, dry conditions.

Seek a conservator for active flaking, mould, structural failure, rare materials, protected wildlife products or uncertain earlier treatments.
