How do I hang a heavy overmantel mirror?

Large overmantel mirrors require professional wall anchoring directly into structural studs or masonry using heavy-duty brackets. Due to their substantial weight, relying on standard picture wire is unsafe. Ensure the hanging mechanism distributes the load evenly across the frame's internal wooden structure. Professional installers can assess the wall composition before mounting.

What is the difference between gesso and carved wood?

Carved wood involves shaping the actual timber foundation with chisel and gouge, while gesso is a plaster mixture applied over wood to build up relief decoration. Many antique frames combine both techniques. Fine details like acanthus leaves were frequently moulded in gesso over a simpler wooden core to achieve high-relief ornamentation efficiently.

Can I date a mirror by its glass plate?

Antique glass plates often exhibit subtle imperfections, uneven thickness, or foxing spots that indicate age. Original mercury glass provides a distinctive, deeper reflection compared to modern float glass. However, mirror plates were frequently replaced during the working life of a frame, so the glass must be evaluated alongside the timber construction and backing boards.
