How do I hang a heavy pair safely?

Heavy antique frames require robust fixings secured directly into wall studs or masonry rather than relying solely on plaster. Professional mirror hangers utilise D-rings and steel wire rated well above the combined weight of the timber and glass. Positioning the pair at eye level ensures balanced visual weight across the room. Spacing them correctly maintains the architectural symmetry intended by the original maker.

Can I clean historic mirror glass?

Historic glass requires gentle cleaning with a soft microfibre cloth and a minimal amount of distilled water or mild glass cleaner. Avoid spraying liquid directly onto the glass, as moisture can seep behind the plate and damage vulnerable silvering or mercury backing. Take care to keep moisture away from the giltwood or gesso frame edges. Water causes traditional water gilding and chalk-based gesso to soften and flake off.

Why do antique mirrors look dark?

Older mirrors often utilise silver nitrate or mercury backing that oxidises over long periods. This chemical ageing creates characteristic dark spots, foxing, and a softer, less clinical reflection than modern float glass. Many collectors prize this natural patination as proof of great age and authenticity. The gentle distortion adds historic character that modern reproductions cannot replicate.

How do I spot a matched pair?

Examine the frames side by side under consistent light to compare wood grain, carving depth, and wear patterns. True pairs exhibit identical tool marks and proportionate dimensions that confirm they were carved in tandem. Check the reverse of both frames for matching carpenter marks, stamps, or labels. Discrepancies in construction techniques often indicate a marriage of two separate single mirrors.
