How do I identify original mercury glass?

Original mercury glass reveals a deeper, softer reflection compared to modern silver nitrate mirrors. Look for characteristic dark patches, mottling, and imperfections behind the glass. These natural signs of ageing develop as the metallic backing reacts to air and moisture over centuries. Modern replacements lack this specific historic depth and uneven foxing pattern.

What is a trumeau mirror?

A trumeau mirror incorporates a decorative wooden panel mounted directly above the glass plate. These architectural fittings were built to integrate seamlessly wall panel panelling in grand rooms. They often feature painted scenes or carved neoclassical reliefs within the upper section. The combination of art and reflection served to brighten and visually expand period interiors.

How should I clean antique glass frames?

Cleaning requires a soft, dry cloth to remove dust from delicate giltwood and carved wooden surfaces. Avoid using commercial sprays or water near gilded areas to protect the gold leaf. For the glass plate itself, apply a minimal amount of gentle cleaner directly to the cloth rather than the mirror. This prevents moisture from seeping behind the plate and accelerating damage to the silvered backing.

What distinguishes Louis XV from Louis XVI mirrors?

Louis XV mirrors showcase asymmetric Rococo curves, C-scrolls, and organic floral motifs. The overall aesthetic feels fluid, theatrical, and dynamic. Louis XVI pieces introduce straight lines, symmetry, classical urns, and rectangular geometry derived from Neoclassical taste. The frames become more restrained and architectural in their decorative vocabulary.
