Are original mirror plates common?

Original glass plates survive in select eighteenth and nineteenth-century examples, identifiable by slight distortions, oxidation, and foxing. These authentic panels contribute significantly to the historic character of the object. Replacement glass often appears in pieces that underwent restoration during their working lives. Examining the silvering from the reverse side helps determine the age of the plate.

How do I clean an antique gilt frame?

Dusting requires a very soft, dry brush to remove particles without disturbing delicate gold leaf or gesso surfaces. Moisture and chemical cleaners must be avoided entirely to prevent permanent damage to historical finishes. Professional conservators should handle any deep cleaning or consolidation of flaking gilding. Gentle maintenance preserves the existing patina and historic integrity.

How do I distinguish Georgian from revival pieces?

Authentic Georgian frames exhibit period construction methods, hand-cut joinery, and specific timber ageing characteristics consistent with the eighteenth century. Revival pieces made around nineteen-twenty often show machine assistance or different secondary woods. Comparing the style of the carving and the composition of the backing boards clarifies the date of manufacture. Dealers often specify revival pieces in their descriptions.
