How do I date a gilt mirror?

Dating relies on examining the frame construction, backboards, and the type of glass used. Eighteenth-century pieces often feature pinned construction and hand-beveled plates, while Victorian examples utilise machine-rolled glass and heavier gesso mouldings. Secondary clues include assembly marks, screw types, and the stylistic vocabulary of the carving, such as Rococo scrolls versus Neoclassical symmetry.

Where should I hang an overmantel mirror?

These mirrors traditionally sit directly above a fireplace mantelpiece, anchored securely to wall studs due to their considerable weight. They can also function as leaner mirrors placed directly on the floor against a wall. Placement should account for what the glass reflects, positioning the piece opposite a window to maximise natural light or facing a focal point in the room.

What is mercury glass?

Mercury glass is a double-walled blown glass object or mirror plate silvered between the layers with a liquid mercury amalgam. It produces a distinctive speckled, dark reflection with age. This historical manufacturing method gives antique mirrors their characteristic foxed appearance, separating them from modern uniform silvering.
