What is a convex mirror used for?

Historically, a convex mirror provided servants with a wide-angle view of a dining room or parlour to anticipate the needs of guests. In modern interiors, these pieces function primarily as decorative focal points that bounce natural light across a room and create an illusion of expanded space.

How do I date an ebonised convex mirror?

Dating relies upon examining the construction techniques of the wooden frame, the composition of the gesso, and the characteristics of the mirror glass itself. Regency examples often feature deep circular mouldings and elaborate crests, while Victorian and Edwardian pieces show subtle variations in scale and secondary woods. Checking the reverse of the frame for original backing boards and old fixings also helps establish the correct period of manufacture.

Why are they called sorcerers mirrors?

The curved glass produces a distorted, wide-angle reflection that captures an entire room within a single circular frame. This optical effect earned the pieces the colloquial title of sorcerer's mirrors or convex butler's mirrors during the nineteenth century. Such descriptors highlight their dual role as optical novelties and sophisticated wall furnishings.

Where should I hang a convex mirror?

These mirrors command attention and work best hung at eye level on a principal wall where the curved glass can capture passing light and activity. Placing them opposite a window or fireplace maximises their ability to illuminate darker corners of a room. Due to their weight, particularly those with heavy gesso and wooden frames, they require secure fixings anchored directly into structural wall supports.
