What is an ebonised slip?

An ebonised slip is the dark, blackened inner ring of wood that sits directly against the mirror glass. It provides a stark visual contrast that draws the eye toward the centre of the plate. This dark border separates the reflective surface from the gilded or carved outer frame, a technique commonly found on nineteenth-century convex mirrors.

Why are convex mirrors curved?

Convex mirrors are curved outward to capture a wide-angle, panoramic view of an entire interior space. Historically, this allowed servants to monitor activity across a large room from a single vantage point. Today, they remain popular for the distinct spatial depth and distorted reflection they introduce to hallway and living room walls.

How do I date a convex mirror?

Dating a convex mirror involves examining the construction methods of the pine carcase, the composition of the gesso, and the style of any crests like eagles. Regency examples often feature crisp, high-relief carving and specific classical proportions. Later nineteenth-century and early twentieth-century revivals typically exhibit slight variations in timber preparation, backboards, and the formulation of the gilding.

Where should I hang a convex mirror?

These mirrors suit principal reception rooms, hallways, or above a fireplace mantel where their wide-angle reflection can open up the space. Because they pull light from all corners of an interior, positioning them opposite a window maximises their brightness. Ensure the wall fixings are secure, as the combined weight of the timber frame, gesso, and glass can be substantial.
