What is a convex mirror?

A convex mirror uses a curved glass plate to reflect a wide panoramic view of a room. These round looking glasses were historically used by butlers to monitor staff or guests discreetly. Today, they serve primarily as decorative focal points that add depth and ambient light to hallways and reception rooms.

How do I hang a heavy mirror safely?

Heavy circular frames require robust wall fixings secured directly into masonry or solid wall studs. Professional mirror hangers use rated brackets that match the weight of the timber and glass. Check the integrity of the original hanging loops on the frame before installation to ensure the piece is fully supported.

What is mirror foxing?

Foxing refers to the dark spots and mottled patches that develop behind the glass over decades. Moisture and chemical reactions cause the silvering to degrade in a characteristic pattern. Collectors prize genuine foxing because it proves the antiquity of the glass plate rather than being a modern replacement.

How do I date an antique mirror?

Dating relies on examining the construction methods of the frame, the type of wood, and the characteristics of the glass plate. Regency frames often feature distinct gesso balls and convex glass, while Art Deco pieces show geometric framing or etching. Comparing the backing boards, fixings, and overall style against documented period examples helps confirm the age.
