A baluster vase with purple clematis on a creamy ground, signed Gallé. The finest glass of art nouveau, and also the most copied. Read only the signature and skip the rest, and you can easily pay hundreds of euros for decorative glass worth fifty.

Topic of the week

Emile Gallé (1846-1904) of Nancy was a glass artist, furniture designer and passionate botanist. In 1901 he co-founded the École de Nancy, the collective that shaped French art nouveau. His most famous technique is cameo glass: two to four layers of coloured glass, with the decoration etched out using hydrofluoric acid and, on the best pieces, finished on the wheel.

After his death in 1904 the firm continued production into the 1930s. That factory output is fully collectable glass. The trouble lies with what came later: Romanian TIP glass with the mark ground off, and modern reproductions carrying a fake signature.

Object of the week

The type you will meet most often: a baluster vase of 25 to 35 centimetres, three layers of glass, clematis or hydrangea decoration in purple and aubergine on a cream to salmon ground, signed Gallé in cameo relief. These were the so-called vases de commerce, the workshop's standard production, made in series even in their own day.

Such vases surface weekly on Catawiki, at Flemish auction houses such as Bernaerts and at flea markets. That is exactly why copyists love them: the model is familiar, demand is high, and buyers often look no further than the name.

Five checks on a Gallé vase

The signature. A genuine Gallé signature is worked into the glass, in relief or engraved, and matches the style of the decoration. A star before the name means factory production between 1904 and around 1914. If TIP appears next to it, you are looking at Romanian decorative glass.
Raking light on the signature area. Tilt the vase against the light. A dull, ground patch next to or above the name often betrays a removed TIP mark. This is the most common Gallé deception.
Count the layers. Real cameo glass consists of two to four layers of coloured glass. At the edge of the decoration you can feel and see a clear relief step. Painted or enamelled decoration on a single layer is not cameo.
The decoration itself. Gallé was a botanist. Flowers and insects are anatomically right, with depth and tonal transitions in the etching. Copies are stiff, symmetrical and flat.
Weight and finish. Many modern copies are thick and heavy, with coarse bubbles and a rough base. Study the foot rim: age wear should be fine and irregular, not machine-even.

Did you know

The star before the signature was not a trick but an honest statement: between 1904 and around 1914 the firm used it to show that the master himself no longer took part. A star is therefore not a sign of forgery, it is a dating aid. Collectors treat star Gallé as a category of its own.

Deeper dive

The TIP story deserves nuance. In the 1970s and 1980s Romanian workshops made cameo glass after Gallé models and marked it honestly with TIP, short for type. Legitimate decorative glass in itself, often competently made. The fraud only starts when a seller grinds off the TIP mark and offers the piece as an original.

On top of that comes a steady stream of modern reproductions, often from Asian workshops, with a fake Gallé signature moulded straight in. You recognise them by the combination: thick, heavy glass, loud colours without transitions, stiff decoration and a signature that sits too large and too prominently on the body.

Market & value

Standard vases de commerce fetch roughly 400 to 3,000 euros, depending on size, decoration, colour contrast and condition. Catawiki and Bonhams show results in that band every week. Star Gallé sits in the same range; with good decoration the star barely lowers the price.

The top segment is another world: marqueterie de verre and the mould-blown vases with rhododendron or wisteria decoration reach tens of thousands of euros and more at Christie's and Sotheby's. Romanian TIP glass with its mark intact is honest decorative glass and usually stays under 200 euros.

Question of the week

“My vase is signed Gallé, but there is a small star before the name. Is it a copy?”

No. The star means factory production between 1904 and around 1914, after Emile Gallé's own death. It is not a forgery but an honest dating mark, and such vases are fully collectable. The five checks above still apply: star vases get copied too.
