How can I tell if an Art Nouveau vase is authentic?

Look for a signature that is integral to the piece — wheel-engraved, acid-etched or inlaid — from makers such as Gallé, Daum, Legras or Loetz. Naturalistic motifs should be worked into the material itself, not simply painted on. For high-value pieces, an independent specialist appraisal is the surest guarantee.

What do Art Nouveau antiques typically cost from a dealer?

Prices vary widely by maker and condition. Expect £500–3,000 for an unsigned workshop chair or occasional table, £5,000–30,000 for a stamped Majorelle sideboard, and considerably more for a documented exhibition piece or large signed Gallé lamp with original shade.

How should I care for Art Nouveau marquetry furniture?

Avoid direct sunlight and sudden changes in humidity, both of which are damaging to veneers and inlays. Clean with a thin coat of uncoloured beeswax, applied and buffed gently. For any restoration work, use a cabinetmaker who specialises in period furniture to preserve original bronzes and inlaid decoration.

Can Art Nouveau antiques be shipped internationally?

Yes. Most professional dealers on the portal offer shipping across Europe and worldwide. Glassware and ceramics are packed in custom crates with specialist foam. For high-value items, ad valorem transit insurance is strongly recommended — ask your dealer to arrange this before dispatch.

Is Art Nouveau exclusively a French style?

Not at all. The movement was international: alongside the École de Nancy and Guimard, notable producers include Austrian Loetz glassworks, Belgian Boch Frères ceramics, René Lalique jewellery and the Catalan school in Barcelona. This portal focuses primarily on French-made or French-provenance pieces.
