How do I identify an 18th-century frame?

Eighteenth-century frames typically utilise solid walnut or mahogany with hand-cut fretwork and subtle gilding on specific carved highlights. Examining the backboards and construction fixings reveals the age of the joinery. Older mirror plates often exhibit minor distortions and silvering degradation that differ markedly from modern machine-rolled glass.

What is the difference between walnut and mahogany frames?

Walnut frames dominate the earlier Georgian periods, often featuring rich grain patterns beneath partial gilding. Mahogany frames tend to appear in later eighteenth-century designs and nineteenth-century revivals. Both timbers provide stable foundations for intricate hand carving and fretwork piercing.

How do I care for antique gilt surfaces?

Antique gilt and parcel gilt surfaces require gentle dusting with a soft dry brush rather than liquid cleaners or chemical polishes. Moisture can damage the underlying gesso and lift fragile gold leaf. Keeping mirrors away from direct sunlight and damp environments preserves both the timber frame and the historic glass plate.
