How do I date a mirror?

Dating relies on combining the timber species, framing style, and the manufacturing technique of the glass plate itself. Earlier pieces often display hand-beveled edges combined with heavy oak or gilt gesso frames typical of Victorian and Edwardian production. Later interwar pieces lean towards geometric art deco lines, sometimes featuring etched motifs or coloured glass panels. Examining the original backing boards and fixings also provides reliable clues to the decade of manufacture.

Are these mirrors heavy to hang?

Many pieces possess substantial weight due to thick timber frames and heavy glass plates used in the nineteenth and early twentieth centuries. Solid oak and giltwood constructions require sturdy wall fixings secured directly into studs or masonry. Checking the original hardware on the reverse indicates how the maker intended the object to bear its own load safely. Professional mirror hangers often recommend using split battens or heavy-duty D-rings for larger wall-mounted items.

How should I clean the glass?

Cleaning requires a soft microfiber cloth and a mild, ammonia-free glass cleaner sprayed onto the cloth rather than directly onto the surface. This prevents moisture from seeping behind the frame and damaging the aged silver backing. Special care must be taken around the bevelled edges and any foxed areas where the original silvering has thinned over the decades. Harsh chemical sprays or abrasive pads will permanently scratch both the glass and the surrounding wooden or gilt frame.

What is foxing on a mirror?

Foxing refers to the small spots, dots, or cloud-like patches that develop in the reflective silver coating behind the glass over many decades. Moisture and atmospheric exposure gradually break down the metallic layers, creating this distinctive aged appearance. Many collectors view light foxing as a desirable sign of authenticity and age rather than a fault. It proves the glass plate is genuinely antique rather than a modern replacement.
