The Story Behind This Mirror
Restraint is a decision, not an absence. On a frame like this the carver has only four corners, two side bosses and two shells to work with, and long plain rails in between - which means each carved passage carries far more weight than it would on a densely worked frame. A corner scroll that is slightly shallow, or a shell whose flutes are not evenly spaced, has nothing nearby to distract from it.
The plain rails matter just as much. A polished plain surface under gold shows every ripple, so the rails are worked with scrapers rather than only abrasive, and the mitres are dry-fitted until they close without pressure - a visible joint on a slim frame ruins the outline the whole design depends on.
The shells are shaped from the solid with their flutes standing proud, the oval bosses carved and set into scrolled surrounds, and the corner acanthus undercut so it lifts clear of the rail. The beaded border is run last around the aperture. Then hand-sanding through progressive grits, gold in coats, rubbed back at the beads, shell ridges and scroll tips, and the plate fitted at the end.
