How do I clean an antique mirror plate?

Use a soft, dry microfibre cloth to remove dust from the glass surface without applying excessive pressure. Avoid standard commercial glass cleaners, as moisture can seep behind the old backing and accelerate the degradation of the silvering. For stubborn marks, apply a minimal amount of distilled water to the cloth rather than directly to the glass. Gently wipe the surface and dry it immediately to protect the historic plate.

What is a foxed mirror plate?

A foxed mirror plate exhibits speckled dark spots and mottled discoloration where the reflective backing has oxidised over time. This chemical reaction occurs naturally as air and moisture interact with the silver or mercury behind the glass. Collectors prize foxed plates for the atmospheric, softened reflection they produce. They indicate genuine age rather than modern artificial distressing.

Can these mirrors be hung safely?

Large mirrors require robust wall fixings anchored directly into structural studs or masonry to support their considerable weight. Professional installation is recommended, particularly for substantial overmantle formats. Check that the original hanging loops or added steel brackets on the wooden frame remain secure before mounting. Distribute the weight evenly using appropriate heavy-duty picture wire or mirror plates.

How do I identify a French antique mirror?

French antique mirrors often feature carved wood and gesso frames styled in French Rococo, Louis Philippe, or provincial designs. The backboards typically consist of wide pine or hardwood planks held together with traditional joinery. Look for nuanced paint patination and characteristic giltwood finishes typical of nineteenth-century workshops. The proportion tends to favour taller vertical formats or wide overmantle designs.
