What is an overmantle mirror?

An overmantle mirror is a wide format glass created to sit directly above a fireplace hearth. These items historically anchored the decorative scheme of a Victorian or Georgian reception room. Their generous dimensions reflect light back into the living space while utilising the architectural focal point of the chimney breast.

How do I clean an antique gilt frame?

Cleaning requires a soft dry brush or feather duster to gently remove surface dust from intricate carved crevices. Moisture and commercial chemical cleaners must be avoided entirely to prevent stripping the delicate gold leaf or softening the gesso underneath. Preserving the original surface patina depends on minimal intervention and gentle handling during routine maintenance.

How can I tell a Victorian mirror from an 18th century one?

Eighteenth-century pieces typically feature hand-carved wooden frames with organic asymmetry and distinct gesso layering beneath gold leaf. Victorian interpretations often incorporate machine-moulded composition ornament and standardised backing construction. Examining the silvering on the glass plate and the construction joints at the corners provides further clues regarding the actual period of manufacture.
