What periods do these dishes come from?

The pieces span the Edwardian era, the nineteen-twenties, and the nineteen-thirties. The vast majority date to the interwar Art Deco period. Production during these decades utilised specialised glass formulae that created the characteristic opalescent light effects.

How were these dishes originally used?

Many functioned as decorative bowls, chargers, sweetmeat dishes, or ashtrays for display in domestic interiors. Their primary role was decorative rather than purely utilitarian. The reflective opalescence made them effective centrepieces on tables and sideboards under interior lighting.

How do I identify Art Deco opalescent glass?

Look for characteristic period motifs such as stylised flowers, fish, birds, and geometric low-relief patterns. The glass itself exhibits a milky blue or amber optical shift. Most pieces from this era bear signatures or registration numbers moulded directly into the glass.

Are these pieces signed by makers?

Many examples feature moulded signatures, etched marks, or registration numbers on the underside or rim. Makers such as René Lalique and Sabino frequently marked their production. Unsigned pieces or those bearing retail marks also appear from period manufacturers.
