How do I tell Art Nouveau from Art Deco pieces?

Art Nouveau items feature flowing, asymmetrical lines inspired by natural forms such as flowers, vines, and insects. The decoration often wraps organically around the contours of the vase. Art Deco pieces emphasise symmetry, bold geometric patterns, and stylised motifs. The overall form tends to be more structured and architectural.

What is opalescent glass?

Opalescent glass is a type of glass that exhibits a milky, translucent quality with shifting tones depending on the light source. It often glows with blue or amber highlights. This optical effect was achieved through specific chemical additions during the melting process, making it particularly prized by twentieth-century designers.

Were these vases used for holding water?

Many of these vessels were designed primarily as decorative display pieces or centrepieces rather than functional flower holders. Their sculptural forms and delicate cameo surfaces meant owners often displayed them empty. When water was used, owners exercised caution to protect interior surfaces and any delicate enamel or acid-etched details from mineral deposits.
