Rare Val Saint Lambert (VSL) "Oignon de Jemeppe" Vase – Art Nouveau Electroformed Copper on Glass – c. 1900-1920

Description:
A fascinating and historically significant antique vase, known by the model name "Oignon de Jemeppe" , attributed to the Art Nouveau production era of Val Saint Lambert (VSL), Belgium. This piece belongs to a rare series of glassware produced using the sophisticated Galvanoplastie (Electroforming) technique, where a layer of metal (likely copper or bronze) is electrically deposited onto the glass form before being treated with a dark patina.

Historical Context:
Origin: The style is associated with the Jemeppe glassworks, which was acquired by Val Saint Lambert in 1883. Pieces from this era combine VSL glass with metallic art finishes.
Style: Art Nouveau (Early 20th Century). The smooth, organic "onion" shape of the foot transitioning into a slim, straight neck, combined with the stylized engraved details (likely bamboo leaves) on the metallic surface, is characteristic of the period.

Specifications:
Material: Glass/Crystal core with Electroplated (Galvanoplastie) Copper/Bronze finish.
Colour: Dark patinated metallic finish (bronze/copper tone).

Authenticity: Unsigned , which is common for pieces finished with this galvanoplastic process.
