Antique Frame Identification: Gilt, Gesso and Why Empty Frames Sell

Dealers whisper it constantly: the frame's the sale. Period frames — especially gilded ones — have their own connoisseurship, market and forgery problems, independent of whatever they hold.

Construction dating

Corners first: mortise-and-tenon or splined hand joints (early) vs machine-mitered-and-nailed (later) vs V-nails (modern); backboards, nail and screw evidence, old hanging hardware and wire types all date. Original back patina — undisturbed oxidation, old labels — versus fresh saw cuts tells renovation history.

Ornament: carved vs compo

Run a fingernail (gently) and look at damage points: carved wood ornament shows grain through the gesso and breaks along wood logic; composition ("compo") — the moulded putty ornament dominating from the late 18th c. — shows cast repetition, shrinkage cracks across the ornament (compo's signature craquelure), and chips revealing brown putty. Both are legitimate and datable; compo enabled the great 19th-century gilt frames, and pressed-brass and gutta-percha corners mark other eras.

Gilding literacy

• Water gilding: gold leaf on gesso-and-bole (look for red/yellow clay at wear points), burnished to mirror highlights — the fine tradition; it can be re-burnished and shows genuine leaf overlaps (faint squares).
• Oil gilding: leaf on size — matte, durable, no burnish.
• Bronze paint "gilding": the repro/refresh tell — brassy, greenish with age, no leaf lines; radiates instant-antique jobs.
• Honest wear gilds the diagnosis: high-point rub to bole on real age vs uniform 'antiqued' rub.

Style eras, fast

Carved Baroque/Rococo swagger → neoclassical restraint (fluting, pearls) → Empire architectural → Victorian compo exuberance and deep 'cove' frames → Eastlake incised gilt → Arts & Crafts quartersawn oak (the era's fingerprint) → Deco geometry → mid-century minimal. Frame era should plausibly pair with the art's era — mismatches are normal (reframing happens) but flag married ensembles sold as original pairs.

The empty-frame market

Good period frames sell bare: standard sizes in honest gilt bring $50–400; big carved/compo showpieces and labeled makers (Newcomb-Macklin, Foster Bros., Stanford White designs) run to thousands. Condition math: original gilt with honest wear beats bronze-painted "restoration" every time (restraint doctrine).

Workflow

Photograph corners (front and back), ornament close, wear points (guide); the Antique Identifier app reads era, ornament type and gilding character; comps by size-style-condition — measured rabbet size included, because frame buyers shop by the hole.

The bottom line

Corners date, chips confess (wood vs compo), bole betrays real leaf, bronze paint betrays everything. Appraise the frame as its own object — it often outbids its occupant.
