Buying guide
What makes an ornate frame valuable
Frame value comes down to three things: whether the ornament was carved by hand or cast from moulding compound, whether the gold is real gilding or paint, and whether anyone has “restored” it since. A hand-carved, water-gilded period frame in honest condition can be worth several times the painting inside it. A Victorian compo frame that someone has gone over with bronze paint is worth almost nothing.
Carved wood versus composition
Until the late eighteenth century, ornament on a good frame was carved into wood — usually limewood or pine — then covered in gesso and gilded. From the 1770s onwards the trade increasingly used composition, or “compo”: a putty of chalk, resin, glue and linseed oil pressed into carved boxwood moulds, applied to a plain wooden carcass while still pliable. It is not a fake — compo frames are period objects too — but it is faster, cheaper and repeatable, and the market prices it accordingly.
Telling them apart, in order of reliability:
- Repetition. Cast ornament repeats exactly. Find two instances of the same motif along a rail and compare them closely: if every leaf vein and every flaw matches, it came out of the same mould. Hand-carving varies, always.
- Undercutting. A carver can cut in behind a leaf so it stands free of the ground, with a real shadow gap you can get a fingernail into. Moulded compo cannot do this — it has to release from the mould, so the ornament tapers outward and sits on the surface.
- Shrinkage cracks. Compo shrinks as its oils dry over decades, producing a characteristic fine crazing across the ornament, and often cracks running with the grain of the timber beneath. Carved wood does not craze like this.
- Losses. When compo breaks off you see a putty-coloured layer and then plain carcass wood underneath, with no carving. When carved ornament chips, the wood underneath is shaped.
Water gilding, oil gilding and gold paint
This is the biggest single value determinant, and it is visible to the naked eye once you know the tells.
- Water gilding is the best. Gold leaf laid onto a coloured clay bole over gesso, then burnished with an agate to a mirror finish. The giveaway is a contrast between glowing burnished highlights and matt recesses on the same frame, and a warm red, orange or grey bole showing through where the leaf has worn on the high points. That wear pattern is the honest, desirable kind — it follows the places a frame actually gets handled and dusted.
- Oil gilding is leaf laid on an oil size. It cannot be burnished, so it has an even, slightly duller sheen throughout, with no burnish-versus-matt contrast. Perfectly respectable, generally worth less.
- Bronze powder and gold paint are not gilding. They tarnish to a brown-green with age, sit as a continuous skin over the ornament's detail, and often pool visibly in the recesses. Under magnification you see metallic flakes in a binder rather than a continuous leaf surface with tiny overlap lines.
Gold leaf is laid in squares of roughly 8cm, so a genuinely gilded surface shows faint parallel overlap lines in a grid where the sheets met. Look for those in a raking light. Paint has no such lines.
What destroys value
The single most common way a good frame becomes a cheap one is overpainting. A previous owner decides the worn gilding looks shabby and goes over the whole thing with gold radiator paint. This is close to irreversible in economic terms: removing it without damaging the leaf beneath is skilled, slow work that routinely costs more than the frame is worth afterwards.
Other things the trade marks down hard:
- Wholesale regilding. A uniformly bright, unworn surface on an obviously old frame usually means it has been redone. Original surface — even worn, even with losses — is worth more than a fresh regild.
- Cut-down rails. Frames get resized to fit a different picture. Check the mitres at all four corners: mismatched ornament, a motif that runs off mid-repeat, or one rail whose pattern spacing differs from its opposite means it has been shortened.
- Replaced ornament. Modern compo repairs in a period frame are normal and acceptable in moderation. Look for slightly crisper detail and a different colour under the gilding on repaired sections.
- Woodworm in structure. Old flight holes in the carcass are common and usually fine. Fresh, pale holes with frass mean active infestation, which needs treating before it goes anywhere near other furniture.
Period and style
You do not need to be an expert to place a frame roughly, and roughly is enough to know whether to look harder. Broad British and European families you will meet on the marketplaces:
- Seventeenth-century. Dark, architectural, often carved oak or ebonised pearwood with ripple mouldings. Sober rather than gilded.
- Louis XIII, XIV and XV. Increasingly exuberant carved and gilded ornament — acanthus, shells, pierced corners and centres. Genuine examples are properly valuable; nineteenth-century revivals in compo are common.
- Maratta. The workhorse British eighteenth-century picture frame: a stepped profile with a leaf-and-shield or acanthus outer edge. Still the default for hanging old master paintings, so demand is steady.
- Victorian gilt compo. Heavy, deep, ornament-covered, often enormous. Made in vast numbers. Value sits mostly in size and condition, and the very large ones sell because big period frames are hard to find.
- Watts and Whistler frames. Late nineteenth-century artist- designed frames — reeded, restrained, sometimes with incised decoration. Sought after well beyond what their plainness suggests.
- Arts and Crafts. Hand-beaten, hammered gesso, or plain oak with visible joinery. A strong and rising market.
When the frame is the find
This is the part worth internalising: a nineteenth-century painting of no particular merit in a good period frame is frequently listed at the value of the painting, because the seller is looking at the picture. Framers and dealers buy these deliberately.
The practical consequence is that the rebate size matters commercially. A frame with an internal opening close to a standard size, and especially a large one, has a ready market. An awkward small size has much less. Measure the rebate — the recess the picture sits in — not the outside.
Look also for makers' labels and stamps on the back of the rails. British framers frequently labelled their work, and a legible label from a known firm both dates the frame and adds to it. Photograph any label before it is disturbed; it feeds directly into researching the artist, since a framer's address often places a picture in a city and a decade.
Checking a frame from a listing photograph
Ask the seller for:
- A raking-light shot along one rail, which reveals both gilding type and losses.
- A close-up of one corner mitre and of the same motif in two places.
- The back of the frame, including any labels and the joinery at the corners.
- The rebate measurement, and whether the frame is currently holding glass.
If the painting is the part you actually care about, the companion piece to this is how to tell if a painting is a print or an original, since a good frame around a reproduction is an extremely common combination.
Getting a real opinion
Frame conservation is its own specialism, and gilding in particular is skilled work. An accredited conservator will tell you what the surface is, whether it has been overpainted, and what it would cost to put right — usually far more usefully than a valuation would. The UK routes are listed in where to get a painting authenticated in the UK, which includes the accredited conservator registers.
One piece of practical advice that costs nothing: do not clean a gilded frame. Water dissolves the glue size under water gilding, and a damp cloth can take the gold off in a single wipe. Dust it with a soft dry brush and leave everything else to someone who does it for a living.
