How do I date an antique mirror?

Dating relies on examining the construction of the wooden frame, the backing boards, and the characteristics of the glass plate itself. Older plates often display slight distortions and hand-bevelled edges that differ from machine-made modern equivalents. Style indicators like Regency mahogany or Art Deco geometry also place the piece within a specific era. Comparing the joinery and hardware to known period examples confirms the age of the frame.

What is an overmantel mirror?
