What defines Art Deco glassware?

Art Deco glassware relies on stylised natural forms, geometric symmetry, and strong sculptural relief. Pieces from this movement often combine clear glass with frosted or stained highlights. The aesthetic prioritises bold decorative impact over delicate fragility, making these objects both functional and sculptural.

How do I care for opalescent glass?

Clean opalescent glass gently using lukewarm water and a mild, non-abrasive soap. Avoid harsh chemical cleaners and ultrasonic baths that can damage delicate surfaces or added colour stains. Dry the piece immediately with a soft, lint-free cloth to prevent water spots from forming on the textured areas.

Are these pieces signed?

Many items feature signature marks etched, moulded, or engraved directly into the base or side. These signatures identify the maker or workshop responsible for the production. Signatures vary from simple block capitals to cursive script, depending on the specific studio and production date.

How can I tell frosted from clear glass?

Frosted glass has a textured, matte appearance that diffuses light rather than allowing a clear view through the material. It is achieved through acid-etching or mechanical sandblasting. Clear glass remains transparent and polished, often contrasting directly against frosted relief sections on the same object.
