How were these dishes used originally?

These vessels served as decorative centrepieces, fruit bowls, and vanity accessories on dressing tables. Many functioned as shallow serving dishes or ashtrays in fashionable interwar interiors. Larger chargers and salvers were primarily decorative, displayed on sideboards to showcase the play of light through the opalescent material.

How do I identify Art Deco pieces?

Art Deco examples feature stylised floral motifs, symmetrical geometric patterns, and structured repeating borders. The lines tend to be cleaner and more architectural than earlier organic designs. Plates and bowls from this movement often incorporate bold animal or human figures rendered in high relief.

What causes the blue glow in the glass?

The milky-blue effect results from the inclusion of specific minerals and chemicals in the molten batch that scatter light waves. When the glass cools unevenly in the mould, it catches the light to produce this characteristic opalescence. Different viewing angles alter the colour intensity between blue tones and warm yellows.

How should I display them at home?

Place these glass vessels where natural light can pass through the body to activate the opalescent properties. Open bowls and chargers look best on flat surfaces near windows or illuminated display cabinets. Avoid stacking them, as the heavy moulded glass and raised relief require independent space to prevent surface rubbing.
