Antique Mirrors: Reflecting Centuries of Decorative Art
Antique mirrors are among the most versatile and enduring categories of decorative antiques, spanning from 17th-century Venetian looking glasses to elaborate Victorian overmantels and mid-century modern designs. Beyond their functional purpose, mirrors served as status symbols, architectural elements, and showcases for the finest gilding, carving, and glassmaking techniques of their eras.
Historical Development
- 17th century: Venetian dominance; costly glass mirrors replaced polished metal
- 18th century: French and English supremacy; Chippendale, Adam, and Hepplewhite styles; gilded frames
- Federal/Empire period (1790-1830): American examples with eagle crests, reverse-painted panels
- Victorian era (1837-1901): Overmantels, pier glasses, cheval mirrors; Renaissance Revival, Rococo Revival
- Art Nouveau/Art Deco (1890-1940): Stylized frames, etched mirror glass, geometric designs
- Mid-century modern (1945-1970): Clean lines, sunburst mirrors, mixed materials
Types and Styles
- Pier mirrors: Tall, narrow mirrors designed to hang between windows
- Overmantel mirrors: Wide horizontal mirrors for above fireplace mantels
- Girandoles: Mirrors with integral candle arms for reflecting light
- Cheval mirrors: Full-length freestanding mirrors on pivoting frames
- Convex mirrors: Circular bull's-eye mirrors with eagle or ornamental crests
- Dressing table mirrors: Small tilting mirrors on box or stand bases

Identification and Dating
- Glass quality: Antique mirror glass shows slight waviness, gray or greenish tint, and foxing (dark spots from mercury deterioration)
- Mercury vs. silver: Pre-1900 mirrors used tin-mercury amalgam; silver nitrate replaced it after 1900
- Construction: Hand-cut glass, wooden backboards, hand-forged nails indicate age
- Gilding: Water gilding (burnished, bright) versus oil gilding (matte); original water gilding is most valuable
- Frame analysis: Composition (compo) ornament over wood was used from the late 18th century onward

Collecting Tips
Federal-period American mirrors with eagle crests and reverse-painted tablets represent a strong collecting category with reliable provenance potential. Convex bull's-eye mirrors remain popular with decorators and collectors alike, supporting steady demand. Original gilding, even when worn, is generally preferred over regilding by serious collectors. Always check for replaced mirror glass by examining edges and backing. Victorian overmantels offer dramatic decorative impact at relatively accessible prices compared to 18th-century examples. Mid-century sunburst mirrors have seen strong appreciation driven by interior design trends. When buying, consider how the mirror's size and style will work in modern interiors, as resale depends partly on practical display appeal.
