Antique Mirrors

Authenticating an antique mirror begins with the frame. A carved wood core — typically lime or poplar — coated in gesso and then gilded in gold leaf is the hallmark of traditional manufacture predating the twentieth century. Look closely at the gilding: genuine age produces natural wear along the ridges and an uneven, warm patina that no reproduction can convincingly replicate. Gilding that is uniformly bright and flawless almost always signals a recent restoration or an outright copy.

The glass itself is equally revealing. A period mercury glass mirror displays characteristic oxidation spots, a faint grey cast and a softer reflection than modern silvered glass — the tin-mercury amalgam process was abandoned around 1900 in favour of silver-nitrate backing. Antique Venetian mirrors are distinguished by their wheel-engraved decoration, hand-blown bevels and applied Murano glass ornaments. Be wary of perfectly clear plates set in supposedly old frames: the glass has very likely been replaced.

In terms of budget, a sound Napoléon III or Louis-Philippe mirror typically sells for £250–£1,200. A well-proportioned Louis XV carved gilt trumeau of good quality can reach several thousand pounds, while 18th-century engraved Venetian pieces and large château trumeau mirrors command the highest prices. Always check the corner joints for stability, inspect the carved ornaments for losses, and ask whether any provenance documentation — a dealer label, an auction sticker, an estate inventory — accompanies the piece.
