What is a convex mirror used for?

Historically, convex mirrors offered butlers a discreet panoramic view of a dining room to monitor guests without intruding. They also served as decorative focal points that flooded darker corners with reflected daylight. In modern interiors, they function primarily as striking optical art pieces that expand the perceived depth of a hallway or living room.

How do I clean antique mirror glass?

Clean antique glass gently using a soft microfibre cloth and a mild, ammonia-free solution applied to the cloth rather than directly onto the surface. Avoid harsh commercial glass cleaners that can seep behind the frame and damage vulnerable historical silvering. Exercise caution around areas of foxing or original backing to preserve the natural patina and prevent further degradation of the plate.

How do I date a round antique mirror?

Dating relies on examining the frame style, construction techniques, and the characteristics of the mirror glass itself. Regency pieces typically feature ebonised reeded slips and gilt balls, while Art Deco examples favor geometric simplicity or frameless designs. Inspect the reverse of the frame for original timber backboards, old paper labels, and hand-cut screws which offer further clues regarding the period of manufacture.
