How do I date an old mirror?

Dating relies on examining the construction methods of the wooden frame, the type of timber utilised, and the manufacturing characteristics of the glass plate itself. Older pieces often display hand-cut joinery and subtle irregularities in the glass. Secondary indicators include the style of gesso ornamentation, backboard fixings, and any remnants of historical labels or stamps left by the original cabinetmaker.

What is mercury glass?

Mercury glass refers to double-walled or silvered glass objects manufactured during the nineteenth century using a mercury amalgam. This process gives the reflective surface a deep, misty appearance. Over decades, chemical reactions cause the backing to develop dark spots and foxing, which collectors value as a sign of genuine age.

Where should I hang an overmantel mirror?

Overmantel mirrors traditionally anchor the space directly above a fireplace, reflecting light and creating a focal point in reception rooms. Their substantial horizontal proportions suit wide wall spaces. Ensure the wall fixings are secured into solid masonry or studwork capable of supporting the considerable weight of a heavy wooden and gesso frame.

How do I clean a antique mirror plate?

Cleaning requires a soft, lint-free cloth and a minimal amount of mild, pH-neutral cleaning solution applied to the cloth rather than directly onto the glass. Harsh chemical sprays can seep behind the frame and damage the fragile silvering or mercury backing. Take care near the edges of the plate where the historical backing is most vulnerable to moisture ingress and flaking.
