Are these mirrors original to their glass?

Many nineteenth century and earlier mirrors retain their original silvered glass, which often exhibits subtle foxing and age spots. Replacement glass does occur during restoration, though period glass shows characteristic slight distortions and thickness variations. Examining the backing boards and the fixings holding the glass in place helps determine whether the plate has been changed over time.

How do I clean an antique gilt frame?

Dust giltwood and gesso frames gently with a very soft, dry brush to prevent damage to the delicate gold leaf surface. Avoid using any liquid cleaners, moisture, or chemical sprays, as these can strip the gilding and dissolve the underlying gesso. Professional conservation is recommended if the surface accumulates stubborn grime that dry brushing fails to remove.

How do I tell a Victorian copy from earlier work?

Victorian revival pieces often display machine-assisted elements or standardised carving depths compared to the idiosyncratic chisel marks of seventeenth century work. Tool marks on the reverse of the timber and the composition of the frame joints provide clear indicators of period. Examining the nails, screws, and backboards also reveals the manufacturing technology typical of the Victorian era rather than earlier centuries.
