Are these mirrors original to their glass?

Many nineteenth-century frames retain their original mercury glass plates, identifiable by soft, mottled oxidation and dark speckling. Replacement plates often appear clearer, flatter and lack the characteristic historical imperfections of antique silvering. Inspect the backing boards and fixings to understand whether the mirror plate has been swapped over time. Older plates typically secure into the frame with traditional wooden slips and iron nails.

How do I hang a heavy overmantel mirror?

Secure heavy timber and giltwood mirrors directly into structural wall studs using appropriate masonry fixings or steel brackets. Relying solely on plasterboard leads to failure under the substantial weight of carved wood and glass. Distribute the load across multiple fixing points or a heavy-duty mirror chain attached securely to the frame's original hanging rings. Professional installation is recommended for large pieces exceeding standard weights.

How do I distinguish eighteenth-century pieces?

Early pieces from the seventeen-hundreds display hand-carved pine or fruitwood beneath the gesso, showing tool marks and construction methods consistent with period joinery. The carving style leans toward organic, flowing asymmetry without the heavier, more symmetrical revival tendencies of the later Victorian era. Examine the construction of the corners, the composition of the gesso ground, and the wear patterns on the gilding. Archival clues and timber shrinkage over centuries help confirm genuine period age.
