How are blue moulded art glass vases dated?

Dating relies on stylistic markers associated with Art Nouveau and Art Deco movements, alongside known production spans for specific named models. Signature styles and registry marks provide additional chronological anchors. Changes in glass chemistry, such as the formulation of specific opalescent effects prevalent in the nineteen-twenties, further help place a piece within its decade of manufacture.

What is opalescent glass?

Opalescent glass displays a milky blue appearance under direct surface illumination while shifting to warm amber tones when light passes directly through it. This dual characteristic stems from microscopic particles suspended evenly throughout the cooled material. Designers utilised this optical property to accentuate the high-relief motifs characteristic of twentieth-century moulded vessels and figurines.

How were perfume bottles and powder boxes used?

These vanity items served as functional containers for cosmetics and fragrances on dressing tables throughout the Edwardian and Art Deco eras. Their elaborate moulded designs transformed everyday toiletries into decorative focal points. Many incorporated intricate stoppers or fitted lids featuring figural or floral subjects, combining practical sealing functions with sculptural presence.

Where was most moulded art glass produced?

Production was concentrated primarily in France, where specialised glasshouses and independent artists developed advanced moulding and casting techniques. Regional workshops in Britain also contributed notable pressed glass designs during the nineteen-thirties. French ateliers dominated the luxury market, employing skilled sculptors to model complex figurative and botanical vessels.
