What is mercury glass?

Mercury glass is an early nineteenth-century mirror plate made by sealing a reflective amalgam behind glass, creating a deep, dark reflection. Over time, the silvering naturally deteriorates to form spots and clouds known as foxing. This ageing process gives vintage pieces their distinct character and proves the glass is contemporary with the older frames. Modern replacements lack this unique optical depth.

How do I clean an antique gilt frame?

Dust giltwood and gesso frames gently with a dry, soft brush or a feather duster to prevent dislodging delicate raised ornamentation. Avoid all commercial cleaning sprays, water, and abrasive cloths, which strip gold leaf and soften gesso. Water can penetrate cracks in the old finish and cause the underlying wood to swell or warp. Regular, gentle dusting is all a stable antique surface requires.

Can an overmantel be placed on a floor?

Many large overmantels are heavy enough to rest securely on a mantel shelf while being anchored to the wall for safety. Placing them directly on the floor as leaners creates a relaxed, contemporary interior effect while retaining period scale. When leaning a mirror, secure the top frame to wall anchors to prevent tipping. This method suits rooms with high ceilings where standard hanging height places the glass too high.
