How do I hang a heavy cushion mirror?

Due to the substantial timber and gesso construction of these pieces, secure wall fixing requires heavy-duty mirror plates or French cleats screwed directly into wall studs or masonry. Professional installation is strongly recommended for large overmantle formats. Ensure the hanging wire or integrated brackets distribute the considerable weight evenly across the structural frame rather than relying on decorative crests or moulding joints.

How should I clean the antique glass?

Clean the glass surface gently using a soft microfibre cloth and a mild, ammonia-free glass cleaner sprayed onto the cloth rather than directly onto the mirror. This prevents moisture from seeping behind the plate. Take care around the edges of bevelled and mercury glass where the silvering is older and more vulnerable to moisture ingress.

Are these mirrors suitable for bathrooms?

Bathrooms subject these delicate antique materials to fluctuating humidity and steam that can damage historic gesso, gilding, and the backing of old glass plates. Dry living areas, hallways, and reception rooms provide a much safer environment. If placed in a room with intermittent moisture, ensure adequate ventilation and keep the frame well away from direct water contact.
