How are these vases cleaned safely?

Wash the glass gently in lukewarm water using a mild, non-abrasive detergent and a soft cloth. Avoid harsh scrubbing that might disturb original surface patinas or stains. Dry the vessel thoroughly with a lint-free towel to prevent water spots from settling on the textured surfaces.

What periods do these designs represent?

The listed items date from the 1920 and 1930 decades. This timeframe covers the height of the Art Deco movement in decorative glass. Designs from this era frequently combine stylised natural forms with modern industrial moulding techniques.

How can I tell different models apart?

Identify individual models by studying the specific motifs moulded into the glass body, such as birds, fish, or botanical arrangements. Named pieces like Ceylan or Rampillon feature distinct sculptural reliefs recorded in period catalogues. Comparing the overall silhouette and the placement of the decorative bands clarifies the specific design.

Where should I display these pieces?

Place the glass where natural or artificial light can pass through the body to activate the opalescent and frosted properties. Locations near windows or illuminated shelving allow the shifting tones to become visible. Ensure the surface is stable and secure to support the heavy weight of thick moulded glass.
