How to Care for Giltwood Furniture and Frames

Historic gilding may consist of extremely thin gold leaf over gesso and clay bole. A casual wipe can remove high points or detach entire flakes.

Assess before treatment

Examine the surface without touching it. Look for lifting flakes, powdery gesso, cracks, exposed bole, bronze paint and earlier repairs. Water gilding and oil gilding respond differently to moisture and solvents.

Record the present condition in clear photographs. Work in good natural or neutral light and choose a small, inconspicuous test area. Stop immediately if colour, gloss, coating or fibres move onto a cloth or brush.

A conservative method

If the surface is secure, dust lightly with a very soft brush while a screened low-suction vacuum captures loose particles. Handle the object by sound structural wood, never by projecting ornament. Maintain stable humidity and secure wall fixings.

Proceed gradually and reassess after each pass. More treatment is not always better: stable age, wear and patina can be more important than achieving a uniformly new appearance.

What to avoid

Do not use water, metal polish, household sprays, feather dusters or sticky cloths. Never press down a lifting flake. Commercial gold paint and metallic wax can obscure original leaf and detail.

Keep products away from adjacent materials unless their compatibility is known. Labels such as “natural,” “gentle” or “antique safe” do not prove that a product suits a particular historic coating.

Aftercare

Collect any detached fragments in a labelled container. Consolidation, cleaning and compensation of losses are specialist treatments and should remain distinguishable on close inspection.

Record what was used, where and when. Stable temperature, moderate humidity, careful handling and protection from spills usually do more for long-term preservation than frequent polishing or cleaning.

When specialist help is needed

Consult a conservator if the surface is flaking, sticky, severely stained, decorated, gilded, structurally cracked or associated with a documented maker or important provenance. Testing and restraint protect both appearance and historical evidence.
